You are bidding on the exact item pictured, provided with a Certificate of Authenticity and Lifetime Guarantee of Authenticity.  The military of ancient Rome, according to Titus Livius, one of the more illustrious historians of Rome over the centuries, was a key element in the rise of Rome over "above seven hundred years" from a small settlement in Latium to the capital of an empire governing a wide region around the shores of the Mediterranean, or, as the Romans themselves said, mare nostrum, "our sea."
Titus Flavius Josephus, a contemporary historian, sometime high-ranking officer in the Roman army, and commander of the rebels in the Jewish revolt, describes the Roman people as if they were "born ready armed." At the time of the two historians, Roman society had already evolved an effective military and had used it to defend itself against the Etruscans, the Italics, the Greeks, the Gauls, the maritime empire of Carthage, and the Macedonian kingdoms. In each war it acquired more territory until, when civil war ended the Roman Republic, nothing was left for the first emperor, Augustus, to do except declare it an empire and defend it.  The militarys campaign history stretched over 1300 years and saw Roman armies campaigning as far east as Parthia (modern-day Iran), as far south as Africa (modern-day Tunisia) and Aegyptus (modern-day Egypt) and as far north as Britannia (modern-day England, south Scotland, and Wales). The makeup of the Roman military changed substantially over its history, from its early history as an unsalaried citizen militia to a later professional force, the Imperial Roman army. The equipment used by the military altered greatly in type over time, though there were very few technological improvements in weapons manufacture, in common with the rest of the classical world. For much of its history, the vast majority of Romes forces were maintained at or beyond the limits of its territory, in order to either expand Romes domain, or protect its existing borders. Expansions were infrequent, as the emperors, adopting a strategy of fixed lines of defense, had determined to maintain existing borders. For that purpose they constructed extensive walls and created permanent stations that became cities.

Constantine was the son of Flavius Valerius Constantius, a Roman army officer, and his consort Helena. His father became Caesar, the deputy emperor in the west in 293AD. Constantine was sent east, where he rose through the ranks to become a military tribune under the emperors Diocletian and Galerius. In 305, Constantius was raised to the rank of Augustus, senior western emperor, and Constantine was recalled west to campaign under his father in Britannia (Britain). Acclaimed as emperor by the army at Eboracum (modern-day York) after his fathers death in 306AD, Constantine emerged victorious in a series of civil wars against the emperors Maxentius and Licinius to become sole ruler of both west and east by 324AD.
As emperor, Constantine enacted many administrative, financial, social, and military reforms to strengthen the empire. The government was restructured and civil and military authority separated. A new gold coin, the solidus, was introduced to combat inflation. It would become the standard for Byzantine and European currencies for more than a thousand years. The first Roman emperor to claim conversion to Christianity, Constantine played an influential role in the proclamation of the Edict of Milan in 313, which decreed tolerance for Christianity in the empire. He called the First Council of Nicaea in 325, at which the Nicene Creed was professed by Christians. In military matters, the Roman army was reorganised to consist of mobile field units and garrison soldiers capable of countering internal threats and barbarian invasions. Constantine pursued successful campaigns against the tribes on the Roman frontiers-the Franks, the Alamanni, the Goths, and the Sarmatians-even resettling territories abandoned by his predecessors during the Crisis of the Third Century. The age of Constantine marked a distinct epoch in the history of the Roman Empire. He built a new imperial residence at Byzantium and renamed the city Constantinople after himself (the laudatory epithet of "New Rome" came later, and was never an official title). It would later become the capital of the Empire for over one thousand years; for which reason the later Eastern Empire would come to be known as the Byzantine Empire. His more immediate political legacy was that, in leaving the empire to his sons, he replaced Diocletians tetrarchy with the principle of dynastic succession. His reputation flourished during the lifetime of his children and centuries after his reign. The medieval church upheld him as a paragon of virtue while secular rulers invoked him as a prototype, a point of reference, and the symbol of imperial legitimacy and identity. Beginning with the Renaissance, there were more critical appraisals of his reign due to the rediscovery of anti-Constantinian sources. Critics portrayed him as a tyrant. Trends in modern and recent scholarship attempted to balance the extremes of previous scholarship. Constantine is a significant figure in the history of Christianity. The Church of the Holy Sepulchre, built on his orders at the purported site of Jesus tomb in Jerusalem, became the holiest place in Christendom. The Papal claim to temporal power in the High Middle Ages was based on the supposed Donation of Constantine. He is venerated as a saint by Eastern Orthodox, Byzantine Catholics, and Anglicans. SourcesConstantine was a ruler of major historical importance, and he has always been a controversial figure. The fluctuations in Constantines reputation reflect the nature of the ancient sources for his reign. These are abundant and detailed, but have been strongly influenced by the official propaganda of the period, and are often one-sided. There are no surviving histories or biographies dealing with Constantines life and rule. The nearest replacement is Eusebius of Caesareas Vita Constantini, a work that is a mixture of eulogy and hagiography. Written between 335AD and circa 339AD, the Vita extols Constantines moral and religious virtues. The Vita creates a contentiously positive image of Constantine, and modern historians have frequently challenged its reliability. The fullest secular life of Constantine is the anonymous Origo Constantini. A work of uncertain date, the Origo focuses on military and political events, to the neglect of cultural and religious matters. Lactantius De Mortibus Persecutorum, a political Christian pamphlet on the reigns of Diocletian and the Tetrarchy, provides valuable but tendentious detail on Constantines predecessors and early life. The ecclesiastical histories of Socrates, Sozomen, and Theodoret describe the ecclesiastic disputes of Constantines later reign. Written during the reign of Theodosius II (408-50AD), a century after Constantines reign, these ecclesiastic historians obscure the events and theologies of the Constantinian period through misdirection, misrepresentation and deliberate obscurity. The contemporary writings of the orthodox Christian Athanasius and the ecclesiastical history of the Arian Philostorgius also survive, though their biases are no less firm. The epitomes of Aurelius Victor (De Caesaribus), Eutropius (Breviarium), Festus (Breviarium), and the anonymous author of the Epitome de Caesaribus offer compressed secular political and military histories of the period. Although not Christian, the epitomes paint a favorable image of Constantine, but omit reference to Constantines religious policies. The Panegyrici Latini, a collection of panegyrics from the late third and early fourth centuries, provide valuable information on the politics and ideology of the tetrarchic period and the early life of Constantine. Contemporary architecture, such as the Arch of Constantine in Rome and palaces in Gamzigrad and Córdoba, epigraphic remains, and the coinage of the era complement the literary sources. Early life

Flavius Valerius Constantinus, as he was originally named, was born in the city of Naissus, (today Niš, Serbia) part of the Dardania province of Moesia on 27 February, probably c. 272AD. His father was Flavius Constantius, an Illyrian, and a native of Dardania province of Moesia (later Dacia Ripensis). Constantine probably spent little time with his father who was an officer in the Roman army, part of the Emperor Aurelians imperial bodyguard. Being described as a tolerant and politically skilled man, Constantius advanced through the ranks, earning the governorship of Dalmatia from Emperor Diocletian, another of Aurelians companions from Illyricum, in 284 or 285. Constantines mother was Helena, possibly a Bithynian woman of low social standing. It is uncertain whether she was legally married to Constantius or merely his concubine. It is unclear if Constantine could speak Thracian, his main language being Latin, and during his public speeches he needed Greek translators.

In July 285AD, Diocletian declared Maximian, another colleague from Illyricum, his co-emperor. Each emperor would have his own court, his own military and administrative faculties, and each would rule with a separate praetorian prefect as chief lieutenant. Maximian ruled in the West, from his capitals at Mediolanum (Milan, Italy) or Augusta Treverorum (Trier, Germany), while Diocletian ruled in the East, from Nicomedia (İzmit, Turkey). The division was merely pragmatic: the Empire was called "indivisible" in official panegyric, and both emperors could move freely throughout the Empire. In 288, Maximian appointed Constantius to serve as his praetorian prefect in Gaul. Constantius left Helena to marry Maximians stepdaughter Theodora in 288 or 289. Diocletian divided the Empire again in 293AD, appointing two Caesars (junior emperors) to rule over further subdivisions of East and West. Each would be subordinate to their respective Augustus (senior emperor) but would act with supreme authority in his assigned lands. This system would later be called the Tetrarchy. Diocletians first appointee for the office of Caesar was Constantius; his second was Galerius, a native of Felix Romuliana. According to Lactantius, Galerius was a brutal, animalistic man. Although he shared the paganism of Romes aristocracy, he seemed to them an alien figure, a semi-barbarian. On 1 March, Constantius was promoted to the office of Caesar, and dispatched to Gaul to fight the rebels Carausius and Allectus. In spite of meritocratic overtones, the Tetrarchy retained vestiges of hereditary privilege, and Constantine became the prime candidate for future appointment as Caesar as soon as his father took the position. Constantine went to the court of Diocletian, where he lived as his fathers heir presumptive.

Constantine received a formal education at Diocletians court, where he learned Latin literature, Greek, and philosophy. The cultural environment in Nicomedia was open, fluid and socially mobile, and Constantine could mix with intellectuals both pagan and Christian. He may have attended the lectures of Lactantius, a Christian scholar of Latin in the city. Because Diocletian did not completely trust Constantius-none of the Tetrarchs fully trusted their colleagues-Constantine was held as something of a hostage, a tool to ensure Constantiuss best behavior. Constantine was nonetheless a prominent member of the court: he fought for Diocletian and Galerius in Asia, and served in a variety of tribunates; he campaigned against barbarians on the Danube in 296AD, and fought the Persians under Diocletian in Syria (297AD) and under Galerius in Mesopotamia (298-299AD). By late 305AD, he had become a tribune of the first order, a tribunus ordinis primi. Constantine had returned to Nicomedia from the eastern front by the spring of 303AD, in time to witness the beginnings of Diocletians "Great Persecution", the most severe persecution of Christians in Roman history. In late 302, Diocletian and Galerius sent a messenger to the oracle of Apollo at Didyma with an inquiry about Christians. Constantine could recall his presence at the palace when the messenger returned, when Diocletian accepted his courts demands for universal persecution. On 23 February 303AD, Diocletian ordered the destruction of Nicomedias new church, condemned its scriptures to the flames, and had its treasures seized. In the months that followed, churches and scriptures were destroyed, Christians were deprived of official ranks, and priests were imprisoned. It is unlikely that Constantine played any role in the persecution. In his later writings he would attempt to present himself as an opponent of Diocletians "sanguinary edicts" against the "worshippers of God", but nothing indicates that he opposed it effectively at the time. Although no contemporary Christian challenged Constantine for his inaction during the persecutions, it remained a political liability throughout his life. On 1 May 305AD, Diocletian, as a result of a debilitating sickness taken in the winter of 304-305AD, announced his resignation. In a parallel ceremony in Milan, Maximian did the same. Lactantius states that Galerius manipulated the weakened Diocletian into resigning, and forced him to accept Galerius allies in the imperial succession. According to Lactantius, the crowd listening to Diocletians resignation speech believed, until the very last moment, that Diocletian would choose Constantine and Maxentius (Maximians son) as his successors. It was not to be: Constantius and Galerius were promoted to Augusti, while Severus and Maximinus Daia, Galerius nephew, were appointed their Caesars respectively. Constantine and Maxentius were ignored. Some of the ancient sources detail plots that Galerius made on Constantines life in the months following Diocletians abdication. They assert that Galerius assigned Constantine to lead an advance unit in a cavalry charge through a swamp on the middle Danube, made him enter into single combat with a lion, and attempted to kill him in hunts and wars. Constantine always emerged victorious: the lion emerged from the contest in a poorer condition than Constantine; Constantine returned to Nicomedia from the Danube with a Sarmatian captive to drop at Galerius feet. It is uncertain how much these tales can be trusted. In the WestConstantine recognized the implicit danger in remaining at Galeriuss court, where he was held as a virtual hostage. His career depended on being rescued by his father in the west. Constantius was quick to intervene. In the late spring or early summer of 305AD, Constantius requested leave for his son to help him campaign in Britain. After a long evening of drinking, Galerius granted the request. Constantines later propaganda describes how he fled the court in the night, before Galerius could change his mind. He rode from post-house to post-house at high speed, hamstringing every horse in his wake. By the time Galerius awoke the following morning, Constantine had fled too far to be caught. Constantine joined his father in Gaul, at Bononia (Boulogne) before the summer of 305AD.

From Bononia they crossed the Channel to Britain and made their way to Eboracum (York), capital of the province of Britannia Secunda and home to a large military base. Constantine was able to spend a year in northern Britain at his fathers side, campaigning against the Picts beyond Hadrians Wall in the summer and autumn. Constantiuss campaign, like that of Septimius Severus before it, probably advanced far into the north without achieving great success. Constantius had become severely sick over the course of his reign, and died on 25 July 306 in Eboracum (York). Before dying, he declared his support for raising Constantine to the rank of full Augustus. The Alamannic king Chrocus, a barbarian taken into service under Constantius, then proclaimed Constantine as Augustus. The troops loyal to Constantius memory followed him in acclamation. Gaul and Britain quickly accepted his rule; Iberia, which had been in his fathers domain for less than a year, rejected it. Constantine sent Galerius an official notice of Constantiuss death and his own acclamation. Along with the notice, he included a portrait of himself in the robes of an Augustus. The portrait was wreathed in bay. He requested recognition as heir to his fathers throne, and passed off responsibility for his unlawful ascension on his army, claiming they had "forced it upon him". Galerius was put into a fury by the message; he almost set the portrait on fire. His advisers calmed him, and argued that outright denial of Constantines claims would mean certain war. Galerius was compelled to compromise: he granted Constantine the title "Caesar" rather than "Augustus" (the latter office went to Severus instead). Wishing to make it clear that he alone gave Constantine legitimacy, Galerius personally sent Constantine the emperors traditional purple robes. Constantine accepted the decision, knowing that it would remove doubts as to his legitimacy. Early ruleConstantines share of the Empire consisted of Britain, Gaul, and Spain. He therefore commanded one of the largest Roman armies, stationed along the important Rhine frontier. After his promotion to emperor, Constantine remained in Britain, driving back the tribes of the Picts and secured his control in the northwestern dioceses. He completed the reconstruction of military bases begun under his fathers rule, and ordered the repair of the regions roadways. He soon left for Augusta Treverorum (Trier) in Gaul, the Tetrarchic capital of the northwestern Roman Empire. The Franks, after learning of Constantines acclamation, invaded Gaul across the lower Rhine over the winter of 306-307AD. Constantine drove them back beyond the Rhine and captured two of their kings, Ascaric and Merogaisus. The kings and their soldiers were fed to the beasts of Triers amphitheater in the adventus (arrival) celebrations that followed. 
Public baths (thermae) built in Trier by Constantine. More than 100 metres (328ft) wide by 200 metres (656ft) long, and capable of serving several thousands at a time, the baths were built to rival those of Rome.
Constantine began a major expansion of Trier. He strengthened the circuit wall around the city with military towers and fortified gates, and began building a palace complex in the northeastern part of the city. To the south of his palace, he ordered the construction of a large formal audience hall, and a massive imperial bathhouse. Constantine sponsored many building projects across Gaul during his tenure as emperor of the West, especially in Augustodunum (Autun) and Arelate (Arles). According to Lactantius, Constantine followed his father in following a tolerant policy towards Christianity. Although not yet a Christian, he probably judged it a more sensible policy than open persecution, and a way to distinguish himself from the "great persecutor", Galerius. Constantine decreed a formal end to persecution, and returned to Christians all they had lost during the persecutions. Because Constantine was still largely untried and had a hint of illegitimacy about him, he relied on his fathers reputation in his early propaganda: the earliest panegyrics to Constantine give as much coverage to his fathers deeds as to those of Constantine himself. Constantines military skill and building projects soon gave the panegyrist the opportunity to comment favorably on the similarities between father and son, and Eusebius remarked that Constantine was a "renewal, as it were, in his own person, of his fathers life and reign". Constantinian coinage, sculpture and oratory also shows a new tendency for disdain towards the "barbarians" beyond the frontiers. After Constantines victory over the Alemanni, he minted a coin issue depicting weeping and begging Alemannic tribesmen-"The Alemanni conquered"-beneath the phrase "Romans rejoicing". There was little sympathy for these enemies. As his panegyrist declared: "It is a stupid clemency that spares the conquered foe." Maxentius rebellion
Dresden bust of Maxentius
Following Galerius recognition of Constantine as caesar, Constantines portrait was brought to Rome, as was customary. Maxentius mocked the portraits subject as the son of a harlot, and lamented his own powerlessness. Maxentius, envious of Constantines authority, seized the title of emperor on 28 October 306AD. Galerius refused to recognize him, but failed to unseat him. Galerius sent Severus against Maxentius, but during the campaign, Severus armies, previously under command of Maxentius father Maximian, defected, and Severus was seized and imprisoned. Maximian, brought out of retirement by his sons rebellion, left for Gaul to confer with Constantine in late 307AD. He offered to marry his daughter Fausta to Constantine, and elevate him to Augustan rank. In return, Constantine would reaffirm the old family alliance between Maximian and Constantius, and offer support to Maxentius cause in Italy. Constantine accepted, and married Fausta in Trier in late summer 307AD. Constantine now gave Maxentius his meagre support, offering Maxentius political recognition. Constantine remained aloof from the Italian conflict, however. Over the spring and summer of 307AD, he had left Gaul for Britain to avoid any involvement in the Italian turmoil; now, instead of giving Maxentius military aid, he sent his troops against Germanic tribes along the Rhine. In 308AD, he raided the territory of the Bructeri, and made a bridge across the Rhine at Colonia Agrippinensium (Cologne). In 310AD, he marched to the northern Rhine and fought the Franks. When not campaigning, he toured his lands advertising his benevolence, and supporting the economy and the arts. His refusal to participate in the war increased his popularity among his people, and strengthened his power base in the West. Maximian returned to Rome in the winter of 307-308AD, but soon fell out with his son. In early 308AD, after a failed attempt to usurp Maxentius title, Maximian returned to Constantines court. On 11 November 308AD, Galerius called a general council at the military city of Carnuntum (Petronell-Carnuntum, Austria) to resolve the instability in the western provinces. In attendance were Diocletian, briefly returned from retirement, Galerius, and Maximian. Maximian was forced to abdicate again and Constantine was again demoted to Caesar. Licinius, one of Galerius old military companions, was appointed Augustus in the western regions. The new system did not last long: Constantine refused to accept the demotion, and continued to style himself as Augustus on his coinage, even as other members of the Tetrarchy referred to him as a Caesar on theirs. Maximinus Daia was frustrated that he had been passed over for promotion while the newcomer Licinius had been raised to the office of Augustus, and demanded that Galerius promote him. Galerius offered to call both Maximinus and Constantine "sons of the Augusti", but neither accepted the new title. By the spring of 310AD, Galerius was referring to both men as Augusti. Maximians rebellionIn 310AD, a dispossessed Maximian rebelled against Constantine while Constantine was away campaigning against the Franks. Maximian had been sent south to Arles with a contingent of Constantines army, in preparation for any attacks by Maxentius in southern Gaul. He announced that Constantine was dead, and took up the imperial purple. In spite of a large donative pledge to any who would support him as emperor, most of Constantines army remained loyal to their emperor, and Maximian was soon compelled to leave. Constantine soon heard of the rebellion, abandoned his campaign against the Franks, and marched his army up the Rhine. At Cabillunum (Chalon-sur-Saône), he moved his troops onto waiting boats to row down the slow waters of the Saône to the quicker waters of the Rhone. He disembarked at Lugdunum (Lyon). Maximian fled to Massilia (Marseille), a town better able to withstand a long siege than Arles. It made little difference, however, as loyal citizens opened the rear gates to Constantine. Maximian was captured and reproved for his crimes. Constantine granted some clemency, but strongly encouraged his suicide. In July 310AD, Maximian hanged himself. In spite of the earlier rupture in their relations, Maxentius was eager to present himself as his fathers devoted son after his death. He began minting coins with his fathers deified image, proclaiming his desire to avenge Maximians death. Constantine initially presented the suicide as an unfortunate family tragedy. By 311AD, however, he was spreading another version. According to this, after Constantine had pardoned him, Maximian planned to murder Constantine in his sleep. Fausta learned of the plot and warned Constantine, who put a eunuch in his own place in bed. Maximian was apprehended when he killed the eunuch and was offered suicide, which he accepted. Along with using propaganda, Constantine instituted a damnatio memoriae on Maximian, destroying all inscriptions referring to him and eliminating any public work bearing his image. The death of Maximian required a shift in Constantines public image. He could no longer rely on his connection to the elder emperor Maximian, and needed a new source of legitimacy. In a speech delivered in Gaul on 25 July 310AD, the anonymous orator reveals a previously unknown dynastic connection to Claudius II, a 3rd Century emperor famed for defeating the Goths and restoring order to the empire. Breaking away from tetrarchic models, the speech emphasizes Constantines ancestral prerogative to rule, rather than principles of imperial equality. The new ideology expressed in the speech made Galerius and Maximian irrelevant to Constantines right to rule. Indeed, the orator emphasizes ancestry to the exclusion of all other factors: "No chance agreement of men, nor some unexpected consequence of favor, made you emperor," the orator declares to Constantine. The oration also moves away from the religious ideology of the Tetrarchy, with its focus on twin dynasties of Jupiter and Hercules. Instead, the orator proclaims that Constantine experienced a divine vision of Apollo and Victory granting him laurel wreaths of health and a long reign. In the likeness of Apollo Constantine recognized himself as the saving figure to whom would be granted "rule of the whole world", as the poet Virgil had once foretold. The orations religious shift is paralleled by a similar shift in Constantines coinage. In his early reign, the coinage of Constantine advertised Mars as his patron. From 310AD on, Mars was replaced by Sol Invictus, a god conventionally identified with Apollo. There is little reason to believe that either the dynastic connection or the divine vision are anything other than fiction, but their proclamation strengthened Constantines claims to legitimacy and increased his popularity among the citizens of Gaul. Civil warsSee also: Civil wars of the TetrarchyWar against MaxentiusBy the middle of 310AD, Galerius had become too ill to involve himself in imperial politics. His final act survives: a letter to the provincials posted in Nicomedia on 30 April 311AD, proclaiming an end to the persecutions, and the resumption of religious toleration. He died soon after the edicts proclamation, destroying what little remained of the tetrarchy. Maximinus mobilized against Licinius, and seized Asia Minor. A hasty peace was signed on a boat in the middle of the Bosphorus. While Constantine toured Britain and Gaul, Maxentius prepared for war. He fortified northern Italy, and strengthened his support in the Christian community by allowing it to elect a new Bishop of Rome, Eusebius. Maxentius rule was nevertheless insecure. His early support dissolved in the wake of heightened tax rates and depressed trade; riots broke out in Rome and Carthage; and Domitius Alexander was able to briefly usurp his authority in Africa. By 312AD, he was a man barely tolerated, not one actively supported, even among Christian Italians. In the summer of 311AD, Maxentius mobilized against Constantine while Licinius was occupied with affairs in the East. He declared war on Constantine, vowing to avenge his fathers "murder". To prevent Maxentius from forming an alliance against him with Licinius, Constantine forged his own alliance with Licinius over the winter of 311-312AD, and offered him his sister Constantia in marriage. Maximin considered Constantines arrangement with Licinius an affront to his authority. In response, he sent ambassadors to Rome, offering political recognition to Maxentius in exchange for a military support. Maxentius accepted. According to Eusebius, inter-regional travel became impossible, and there was military buildup everywhere. There was "not a place where people were not expecting the onset of hostilities every day". Constantines advisers and generals cautioned against preemptive attack on Maxentius; even his soothsayers recommended against it, stating that the sacrifices had produced unfavorable omens. Constantine, with a spirit that left a deep impression on his followers, inspiring some to believe that he had some form of supernatural guidance, ignored all these cautions. Early in the spring of 312AD, Constantine crossed the Cottian Alps with a quarter of his army, a force numbering about 40,000. The first town his army encountered was Segusium (Susa, Italy), a heavily fortified town that shut its gates to him. Constantine ordered his men to set fire to its gates and scale its walls. He took the town quickly. Constantine ordered his troops not to loot the town, and advanced with them into northern Italy. At the approach to the west of the important city of Augusta Taurinorum (Turin, Italy), Constantine met a large force of heavily armed Maxentian cavalry. In the ensuing battle Constantines army encircled Maxentius cavalry, flanked them with his own cavalry, and dismounted them with blows from his soldiers iron-tipped clubs. Constantines armies emerged victorious. Turin refused to give refuge to Maxentius retreating forces, opening its gates to Constantine instead. Other cities of the north Italian plain sent Constantine embassies of congratulation for his victory. He moved on to Milan, where he was met with open gates and jubilant rejoicing. Constantine rested his army in Milan until mid-summer 312AD, when he moved on to Brixia (Brescia). Brescias army was easily dispersed, and Constantine quickly advanced to Verona, where a large Maxentian force was camped. Ruricius Pompeianus, general of the Veronese forces and Maxentius praetorian prefect, was in a strong defensive position, since the town was surrounded on three sides by the Adige. Constantine sent a small force north of the town in an attempt to cross the river unnoticed. Ruricius sent a large detachment to counter Constantines expeditionary force, but was defeated. Constantines forces successfully surrounded the town and laid siege. Ruricius gave Constantine the slip and returned with a larger force to oppose Constantine. Constantine refused to let up on the siege, and sent only a small force to oppose him. In the desperately fought encounter that followed, Ruricius was killed and his army destroyed. Verona surrendered soon afterwards, followed by Aquileia, Mutina (Modena), and Ravenna. The road to Rome was now wide open to Constantine. 
The Milvian Bridge (Ponte Milvio) over the Tiber, north of Rome, where Constantine and Maxentius fought in the Battle of the Milvian Bridge
Maxentius prepared for the same type of war he had waged against Severus and Galerius: he sat in Rome and prepared for a siege. He still controlled Romes praetorian guards, was well-stocked with African grain, and was surrounded on all sides by the seemingly impregnable Aurelian Walls. He ordered all bridges across the Tiber cut, reportedly on the counsel of the gods, and left the rest of central Italy undefended; Constantine secured that regions support without challenge. Constantine progressed slowly along the Via Flaminia, allowing the weakness of Maxentius to draw his regime further into turmoil. Maxentius support continued to weaken: at chariot races on 27 October, the crowd openly taunted Maxentius, shouting that Constantine was invincible. Maxentius, no longer certain that he would emerge from a siege victorious, built a temporary boat bridge across the Tiber in preparation for a field battle against Constantine. On 28 October 312AD, the sixth anniversary of his reign, he approached the keepers of the Sibylline Books for guidance. The keepers prophesied that, on that very day, "the enemy of the Romans" would die. Maxentius advanced north to meet Constantine in battle.

Maxentius organized his forces-still twice the size of Constantines-in long lines facing the battle plain, with their backs to the river. Constantines army arrived at the field bearing unfamiliar symbols on either its standards or its soldiers shields. According to Lactantius, Constantine was visited by a dream the night before the battle, wherein he was advised "to mark the heavenly sign of God on the shields of his soldiers... by means of a slanted letter X with the top of its head bent round, he marked Christ on their shields." Eusebius describes another version, where, while marching at midday, "he saw with his own eyes in the heavens a trophy of the cross arising from the light of the sun, carrying the message, In Hoc Signo Vinces or "with this sign, you will conquer"; in Eusebiuss account, Constantine had a dream the following night, in which Christ appeared with the same heavenly sign, and told him to make a standard, the labarum, for his army in that form. Eusebius is vague about when and where these events took place, but it enters his narrative before the war against Maxentius begins. Eusebius describes the sign as Chi (Χ) traversed by Rho (Ρ): ☧, a symbol representing the first two letters of the Greek spelling of the word Christos or Christ. In 315AD a medallion was issued at Ticinum showing Constantine wearing a helmet emblazoned with the Chi Rho, and coins issued at Siscia in 317/318AD repeat the image. The figure was otherwise rare, however, and is uncommon in imperial iconography and propaganda before the 320s. Constantine deployed his own forces along the whole length of Maxentius line. He ordered his cavalry to charge, and they broke Maxentius cavalry. He then sent his infantry against Maxentius infantry, pushing many into the Tiber where they were slaughtered and drowned. The battle was brief: Maxentius troops were broken before the first charge. Maxentius horse guards and praetorians initially held their position, but broke under the force of a Constantinian cavalry charge; they also broke ranks and fled to the river. Maxentius rode with them, and attempted to cross the bridge of boats, but he was pushed by the mass of his fleeing soldiers into the Tiber, and drowned. In Rome

Constantine entered Rome on 29 October 312. He staged a grand adventus in the city, and was met with popular jubilation. Maxentius body was fished out of the Tiber and decapitated. His head was paraded through the streets for all to see. After the ceremonies, Maxentius disembodied head was sent to Carthage; at this, Carthage would offer no further resistance. Unlike his predecessors, Constantine neglected to make the trip to the Capitoline Hill and perform customary sacrifices at the Temple of Jupiter. He did, however, choose to honor the Senatorial Curia with a visit, where he promised to restore its ancestral privileges and give it a secure role in his reformed government: there would be no revenge against Maxentius supporters. In response, the Senate decreed him "title of the first name", which meant his name would be listed first in all official documents, and acclaimed him as "the greatest Augustus". He issued decrees returning property lost under Maxentius, recalling political exiles, and releasing Maxentius imprisoned opponents. An extensive propaganda campaign followed, during which Maxentius image was systematically purged from all public places. Maxentius was written up as a "tyrant", and set against an idealized image of the "liberator", Constantine. Eusebius, in his later works, is the best representative of this strand of Constantinian propaganda. Maxentius rescripts were declared invalid, and the honors Maxentius had granted to leaders of the Senate were invalidated. Constantine also attempted to remove Maxentius influence on Romes urban landscape. All structures built by Maxentius were re-dedicated to Constantine, including the Temple of Romulus and the Basilica of Maxentius. At the focal point of the basilica, a stone statue of Constantine holding the Christian labarum in its hand was erected. Its inscription bore the message the statue had already made clear: By this sign Constantine had freed Rome from the yoke of the tyrant. Where he did not overwrite Maxentius achievements, Constantine upstaged them: the Circus Maximus was redeveloped so that its total seating capacity was twenty-five times larger than that of Maxentius racing complex on the Via Appia. Maxentius strongest supporters in the military were neutralized when the Praetorian Guard and Imperial Horse Guard (equites singulares) were disbanded. The tombstones of the Imperial Horse Guard were ground up and put to use in a basilica on the Via Labicana. On November 9, 312AD, barely two weeks after Constantine captured the city, the former base of the Imperial Horse Guard was chosen for redevelopment into the Lateran Basilica. The Legio II Parthica was removed from Alba (Albano Laziale), and the remainder of Maxentius armies were sent to do frontier duty on the Rhine. Wars against LiciniusIn the following years, Constantine gradually consolidated his military superiority over his rivals in the crumbling Tetrarchy. In 313, he met Licinius in Milan to secure their alliance by the marriage of Licinius and Constantines half-sister Constantia. During this meeting, the emperors agreed on the so-called Edict of Milan, officially granting full tolerance to Christianity and all religions in the Empire. The document had special benefits for Christians, legalizing their religion and granting them restoration for all property seized during Diocletians persecution. It repudiates past methods of religious coercion and used only general terms to refer to the divine sphere-"Divinity" and "Supreme Divinity", summa divinitas. The conference was cut short, however, when news reached Licinius that his rival Maximin had crossed the Bosporus and invaded European territory. Licinius departed and eventually defeated Maximin, gaining control over the entire eastern half of the Roman Empire. Relations between the two remaining emperors deteriorated, as Constantine suffered an assassination attempt at the hands of a character that Licinius wanted elevated to the rank of Caesar; Licinius, for his part had Constantines statues in Emona destroyed. In either 314 or 316 the two Augusti fought against one another at the Battle of Cibalae, with Constantine being victorious. They clashed again at the Battle of Mardia in 317, and agreed to a settlement in which Constantines sons Crispus and Constantine II, and Licinius son Licinianus were made caesars. After this arrangement, Constantine ruled the dioceses of Pannonia and Macedonia and took residence at Sirmium, whence he could wage war on the Goths and Sarmatians in 322, and on the Goths in 323. In the year 320, Licinius allegedly reneged on the religious freedom promised by the Edict of Milan in 313 and began to oppress Christians anew, generally without bloodshed, but resorting to confiscations and sacking of Christian office-holders. Although this characterization of Licinius as anti-Christian is somewhat doubtful, the fact is that he seems to have been far less open in his support of Christianity than Constantine. Therefore, Licinius was prone to see the Church as a force more loyal to Constantine than to the Imperial system in general - the explanation offered by the Church historian Sozomen. This dubious arrangement eventually became a challenge to Constantine in the West, climaxing in the great civil war of 324. Licinius, aided by Goth mercenaries, represented the past and the ancient Pagan faiths. Constantine and his Franks marched under the standard of the labarum, and both sides saw the battle in religious terms. Outnumbered, but fired by their zeal, Constantines army emerged victorious in the Battle of Adrianople. Licinius fled across the Bosphorus and appointed Martius Martinianus, the commander of his bodyguard, as Caesar, but Constantine next won the Battle of the Hellespont, and finally the Battle of Chrysopolis on 18 September 324. Licinius and Martinianus surrendered to Constantine at Nicomedia on the promise their lives would be spared: they were sent to live as private citizens in Thessalonica and Cappadocia respectively, but in 325 Constantine accused Licinius of plotting against him and had them both arrested and hanged; Liciniuss son (the son of Constantines half-sister) was also killed. Thus Constantine became the sole emperor of the Roman Empire. Later ruleFoundation of Constantinople
Coin struck by Constantine I to commemorate the founding of Constantinople
Licinius defeat came to represent the defeat of a rival center of Pagan and Greek-speaking political activity in the East, as opposed to the Christian and Latin-speaking Rome, and it was proposed that a new Eastern capital should represent the integration of the East into the Roman Empire as a whole, as a center of learning, prosperity, and cultural preservation for the whole of the Eastern Roman Empire. Among the various locations proposed for this alternative capital, Constantine appears to have toyed earlier with Serdica (present-day Sofia), as he was reported saying that "Serdica is my Rome". Sirmium and Thessalonica were also considered. Eventually, however, Constantine decided to work on the Greek city of Byzantium, which offered the advantage of having already been extensively rebuilt on Roman patterns of urbanism, during the preceding century, by Septimius Severus and Caracalla, who had already acknowledged its strategic importance. The city was thus founded in 324, dedicated on 11 May 330 and renamed Constantinopolis ("Constantines City" or Constantinople in English). Special commemorative coins were issued in 330 to honor the event. The new city was protected by the relics of the True Cross, the Rod of Moses and other holy relics, though a cameo now at the Hermitage Museum also represented Constantine crowned by the tyche of the new city. The figures of old gods were either replaced or assimilated into a framework of Christian symbolism. Constantine built the new Church of the Holy Apostles on the site of a temple to Aphrodite. Generations later there was the story that a divine vision led Constantine to this spot, and an angel no one else could see, led him on a circuit of the new walls. The capital would often be compared to the old Rome as Nova Roma Constantinopolitana, the "New Rome of Constantinople".

Constantine was the first emperor to stop Christian persecutions and to legalise Christianity along with all other religions and cults in the Roman Empire. In February 313, Constantine met with Licinius in Milan, where they developed the Edict of Milan. The edict stated that Christians should be allowed to follow the faith without oppression. This removed penalties for professing Christianity, under which many had been martyred previously, and returned confiscated Church property. The edict protected from religious persecution not only Christians but all religions, allowing anyone to worship whichever deity they chose. A similar edict had been issued in 311 by Galerius, then senior emperor of the Tetrarchy; Galerius edict granted Christians the right to practise their religion but did not restore any property to them. The Edict of Milan included several clauses which stated that all confiscated churches would be returned as well as other provisions for previously persecuted Christians. Scholars debate whether Constantine adopted his mother St. Helenas Christianity in his youth, or whether he adopted it gradually over the course of his life. Constantine possibly retained the title of pontifex maximus, a title emperors bore as heads of the ancient Roman religion priesthood until Gratian (r. 375-383) renounced the title. According to Christian writers, Constantine was over 40 when he finally declared himself a Christian, writing to Christians to make clear that he believed he owed his successes to the protection of the Christian High God alone. Throughout his rule, Constantine supported the Church financially, built basilicas, granted privileges to clergy (e.g. exemption from certain taxes), promoted Christians to high office, and returned property confiscated during the Diocletianic persecution. His most famous building projects include the Church of the Holy Sepulchre, and Old Saint Peters Basilica. Apparently Constantine did not patronize Christianity alone. After gaining victory in the Battle of the Milvian Bridge (312), a triumphal arch-the Arch of Constantine-was built (315) to celebrate his triumph. The arch is decorated with images of the goddess Victoria. At the time of its dedication, sacrifices to gods like Apollo, Diana, and Hercules were made. Absent from the Arch are any depictions of Christian symbolism. However, as the Arch was commissioned by the Senate, the absence of Christian symbols may reflect the role of the Curia at the time as a pagan redoubt. In 321, he legislated that the venerable day of the sun should be a day of rest for all citizens. In the year 323, he issued a decree banning Christians from participating in state sacrifices Furthermore, Constantines coinage continued to carry the symbols of the sun. After the pagan gods had disappeared from his coinage, Christian symbols appeared as Constantines attributes: the chi rho between his hands or on his labarum, as well on the coin itself. The reign of Constantine established a precedent for the position of the emperor as having great influence and ultimate regulatory authority within the religious discussions involving the early Christian councils of that time, e.g., most notably the dispute over Arianism. Constantine himself disliked the risks to societal stability that religious disputes and controversies brought with them, preferring where possible to establish an orthodoxy. His influence over the early Church councils was to enforce doctrine, root out heresy, and uphold ecclesiastical unity; what proper worship and doctrines and dogma consisted of was for the Church to determine, in the hands of the participating bishops. Most notably, from 313 to 316 bishops in North Africa struggled with other Christian bishops who had been ordained by Donatus in opposition to Caecilian. The African bishops could not come to terms and the Donatists asked Constantine to act as a judge in the dispute. Three regional Church councils and another trial before Constantine all ruled against Donatus and the Donatism movement in North Africa. In 317 Constantine issued an edict to confiscate Donatist church property and to send Donatist clergy into exile. More significantly, in 325 he summoned the Council of Nicaea, effectively the first Ecumenical Council (unless the Council of Jerusalem is so classified), most known for its dealing with Arianism and for instituting the Nicene Creed. Constantine enforced the prohibition of the First Council of Nicaea against celebrating the Lords Supper on the day before the Jewish Passover (14 Nisan) (see Quartodecimanism and Easter controversy). This marked a definite break of Christianity from the Judaic tradition. From then on the Roman Julian Calendar, a solar calendar, was given precedence over the lunisolar Hebrew Calendar among the Christian churches of the Roman Empire. Constantine made some new laws regarding the Jews, but while some of his edicts were unfavorable towards Jews, they were not harsher than those of his predecessors. It was made illegal for Jews to seek converts or to attack other Jews who had converted to Christianity. They were forbidden to own Christian slaves or to circumcise their slaves. On the other hand, Jewish clergy were given the same exemptions as Christian clergy. Administrative reforms.JPG/170px-0_Constantinus_I_-_Palazzo_dei_Conservatori_(2).JPG)

Beginning in the mid-3rd century the emperors began to favor members of the equestrian order over senators, who had had a monopoly on the most important offices of state. Senators were stripped of the command of legions and most provincial governorships (as it was felt that they lacked the specialized military upbringing needed in an age of acute defense needs), such posts being given to equestrians by Diocletian and his colleagues-following a practice enforced piecemeal by their predecessors. The emperors, however, still needed the talents and the help of the very rich, who were relied on to maintain social order and cohesion by means of a web of powerful influence and contacts at all levels. Exclusion of the old senatorial aristocracy threatened this arrangement. In 326, Constantine reversed this pro-equestrian trend, raising many administrative positions to senatorial rank and thus opening these offices to the old aristocracy, and at the same time elevating the rank of already existing equestrians office-holders to senator, degrading the equestrian order -at least as a bureaucratic rank -in the process, so that by the end of the 4th century the title of perfectissimus was granted only to mid-low officials. By the new Constantinian arrangement, one could become a senator, either by being elected praetor or (in most cases) by fulfilling a function of senatorial rank: from then on, holding of actual power and social status were melded together into a joint imperial hierarchy. At the same time, Constantine gained with this the support of the old nobility, as the Senate was allowed itself to elect praetors and quaestors, in place of the usual practice of the emperors directly creating new magistrates (adlectio). In one inscription in honor of city prefect (336-337) Ceionius Rufus Albinus, it was written that Constantine had restored the Senate "the auctoritas it had lost at Caesars time". The Senate as a body remained devoid of any significant power; nevertheless, the senators, who had been marginalized as potential holders of imperial functions during the 3rd century, could now dispute such positions alongside more upstart bureaucrats. Some modern historians see in those administrative reforms an attempt by Constantine at reintegrating the senatorial order into the imperial administrative elite to counter the possibility of alienating pagan senators from a Christianized imperial rule; however, such an interpretation remains conjectural, given the fact that we do not have the precise numbers about pre-Constantine conversions to Christianity in the old senatorial milieu-some historians suggesting that early conversions among the old aristocracy were more numerous than previously supposed. Constantines reforms had to do only with the civilian administration: the military chiefs, who since the Crisis of the Third Century had risen from the ranks, remained outside the senate, in which they were included only by Constantines children. Monetary reformsAfter the runaway inflation of the third century, associated with the production of fiat money to pay for public expenses, Diocletian had tried unsuccessfully to re establish trustworthy minting of silver and billon coins. The failure of the various Diocletianic attempts at the restoration of a functioning silver coin resided in the fact that the silver currency was overvalued in terms of its actual metal content, and therefore could only circulate at much discounted rates. Minting of the Diocletianic "pure" silver argenteus ceased, therefore, soon after 305, while the billon currency continued to be used until the 360s. From the early 300s on, Constantine forsook any attempts at restoring the silver currency, preferring instead to concentrate on minting large quantities of good standard gold pieces-the solidus, 72 of which made a pound of gold. New (and highly debased) silver pieces would continue to be issued during Constantines later reign and after his death, in a continuous process of retariffing, until this bullion minting eventually ceased, de jure, in 367, with the silver piece being de facto continued by various denominations of bronze coins, the most important being the centenionalis. These bronze pieces continued to be devalued, assuring the possibility of keeping fiduciary minting alongside a gold standard. The anonymous author of the possibly contemporary treatise on military affairs De Rebus Bellicis held that, as a consequence of this monetary policy, the rift between classes widened: the rich benefited from the stability in purchasing power of the gold piece, while the poor had to cope with ever-degrading bronze pieces. Later emperors like Julian the Apostate tried to present themselves as advocates of the humiles by insisting on trustworthy mintings of the bronze currency. Constantines monetary policy were closely associated with his religious ones, in that increased minting was associated with measures of confiscation-taken since 331 and closed in 336-of all gold, silver and bronze statues from pagan temples, who were declared as imperial property and, as such, as monetary assets. Two imperial commissioners for each province had the task of getting hold of the statues and having them melded for immediate minting-with the exception of a number of bronze statues who were used as public monuments for the beautification of the new capital in Constantinople. Executions of Crispus and FaustaOn some date between 15 May and 17 June 326, Constantine had his eldest son Crispus, by Minervina, seized and put to death by "cold poison" at Pola (Pula, Croatia). In July, Constantine had his wife, the Empress Fausta, killed in an over-heated bath. Their names were wiped from the face of many inscriptions, references to their lives in the literary record were erased, and the memory of both was condemned. Eusebius, for example, edited praise of Crispus out of later copies of his Historia Ecclesiastica, and his Vita Constantini contains no mention of Fausta or Crispus at all. Few ancient sources are willing to discuss possible motives for the events; those few that do, offer unconvincing rationales, are of later provenance, and are generally unreliable. At the time of the executions, it was commonly believed that the Empress Fausta was either in an illicit relationship with Crispus, or was spreading rumors to that effect. A popular myth arose, modified to allude to Hippolytus-Phaedra legend, with the suggestion that Constantine killed Crispus and Fausta for their immoralities. One source, the largely fictional Passion of Artemius, probably penned in the eighth century by John of Damascus, makes the legendary connection explicit. As an interpretation of the executions, the myth rests on only "the slimmest of evidence": sources that allude to the relationship between Crispus and Fausta are late and unreliable, and the modern suggestion that Constantines "godly" edicts of 326 and the irregularities of Crispus are somehow connected rests on no evidence at all. Although Constantine created his apparent heirs "Caesars", following a pattern established by Diocletian, he gave his creations a hereditary character, alien to the tetrarchic system: Constantines Caesars were to be kept in the hope of ascending to Empire, and entirely subordinated to their Augustus, as long as he was alive. Therefore, an alternative explanation for the execution of Crispus was, perhaps, Constantines desire to keep a firm grip on his prospective heirs, this-and Faustas desire for having her sons inheriting instead of their half-brother-being reason enough for killing Crispus; the subsequent execution of Fausta, however, was probably meant as a reminder to her children that Constantine would not hesitate in "killing his own relatives when he felt this was necessary". Later campaigns

Constantine considered Constantinople his capital and permanent residence. He lived there for a good portion of his later life. He rebuilt Trajans bridge across the Danube, in hopes of reconquering Dacia, a province that had been abandoned under Aurelian. In the late winter of 332, Constantine campaigned with the Sarmatians against the Goths. The weather and lack of food cost the Goths dearly: reportedly, nearly one hundred thousand died before they submitted to Rome. In 334, after Sarmatian commoners had overthrown their leaders, Constantine led a campaign against the tribe. He won a victory in the war and extended his control over the region, as remains of camps and fortifications in the region indicate. Constantine resettled some Sarmatian exiles as farmers in Illyrian and Roman districts, and conscripted the rest into the army. Constantine took the title Dacicus maximus in 336. In the last years of his life Constantine made plans for a campaign against Persia. In a letter written to the king of Persia, Shapur, Constantine had asserted his patronage over Persias Christian subjects and urged Shapur to treat them well. The letter is undatable. In response to border raids, Constantine sent Constantius to guard the eastern frontier in 335. In 336, prince Narseh invaded Armenia (a Christian kingdom since 301) and installed a Persian clien" />

The military of ancient Rome, according to Titus Livius, one of the more illustrious historians of Rome over the centuries, was a key element in the rise of Rome over "above seven hundred years" from a small settlement in Latium to the capital of an empire governing a wide region around the shores of the Mediterranean, or, as the Romans themselves said, mare nostrum, "our sea." Titus Flavius Josephus, a contemporary historian, sometime high-ranking officer in the Roman army, and commander of the rebels in the Jewish revolt, describes the Roman people as if they were "born ready armed." At the time of the two historians, Roman society had already evolved an effective military and had used it to defend itself against the Etruscans, the Italics, the Greeks, the Gauls, the maritime empire of Carthage, and the Macedonian kingdoms. In each war it acquired more territory until, when civil war ended the Roman Republic, nothing was left for the first emperor, Augustus, to do except declare it an empire and defend it. The militarys campaign history stretched over 1300 years and saw Roman armies campaigning as far east as Parthia (modern-day Iran), as far south as Africa (modern-day Tunisia) and Aegyptus (modern-day Egypt) and as far north as Britannia (modern-day England, south Scotland, and Wales). The makeup of the Roman military changed substantially over its history, from its early history as an unsalaried citizen militia to a later professional force, the Imperial Roman army. The equipment used by the military altered greatly in type over time, though there were very few technological improvements in weapons manufacture, in common with the rest of the classical world. For much of its history, the vast majority of Romes forces were maintained at or beyond the limits of its territory, in order to either expand Romes domain, or protect its existing borders. Expansions were infrequent, as the emperors, adopting a strategy of fixed lines of defense, had determined to maintain existing borders. For that purpose they constructed extensive walls and created permanent stations that became cities.

Constantine was the son of Flavius Valerius Constantius, a Roman army officer, and his consort Helena. His father became Caesar, the deputy emperor in the west in 293AD. Constantine was sent east, where he rose through the ranks to become a military tribune under the emperors Diocletian and Galerius. In 305, Constantius was raised to the rank of Augustus, senior western emperor, and Constantine was recalled west to campaign under his father in Britannia (Britain). Acclaimed as emperor by the army at Eboracum (modern-day York) after his fathers death in 306AD, Constantine emerged victorious in a series of civil wars against the emperors Maxentius and Licinius to become sole ruler of both west and east by 324AD. As emperor, Constantine enacted many administrative, financial, social, and military reforms to strengthen the empire. The government was restructured and civil and military authority separated. A new gold coin, the solidus, was introduced to combat inflation. It would become the standard for Byzantine and European currencies for more than a thousand years. The first Roman emperor to claim conversion to Christianity, Constantine played an influential role in the proclamation of the Edict of Milan in 313, which decreed tolerance for Christianity in the empire. He called the First Council of Nicaea in 325, at which the Nicene Creed was professed by Christians. In military matters, the Roman army was reorganised to consist of mobile field units and garrison soldiers capable of countering internal threats and barbarian invasions. Constantine pursued successful campaigns against the tribes on the Roman frontiers-the Franks, the Alamanni, the Goths, and the Sarmatians-even resettling territories abandoned by his predecessors during the Crisis of the Third Century. The age of Constantine marked a distinct epoch in the history of the Roman Empire. He built a new imperial residence at Byzantium and renamed the city Constantinople after himself (the laudatory epithet of "New Rome" came later, and was never an official title). It would later become the capital of the Empire for over one thousand years; for which reason the later Eastern Empire would come to be known as the Byzantine Empire. His more immediate political legacy was that, in leaving the empire to his sons, he replaced Diocletians tetrarchy with the principle of dynastic succession. His reputation flourished during the lifetime of his children and centuries after his reign. The medieval church upheld him as a paragon of virtue while secular rulers invoked him as a prototype, a point of reference, and the symbol of imperial legitimacy and identity. Beginning with the Renaissance, there were more critical appraisals of his reign due to the rediscovery of anti-Constantinian sources. Critics portrayed him as a tyrant. Trends in modern and recent scholarship attempted to balance the extremes of previous scholarship. Constantine is a significant figure in the history of Christianity. The Church of the Holy Sepulchre, built on his orders at the purported site of Jesus tomb in Jerusalem, became the holiest place in Christendom. The Papal claim to temporal power in the High Middle Ages was based on the supposed Donation of Constantine. He is venerated as a saint by Eastern Orthodox, Byzantine Catholics, and Anglicans. SourcesConstantine was a ruler of major historical importance, and he has always been a controversial figure. The fluctuations in Constantines reputation reflect the nature of the ancient sources for his reign. These are abundant and detailed, but have been strongly influenced by the official propaganda of the period, and are often one-sided. There are no surviving histories or biographies dealing with Constantines life and rule. The nearest replacement is Eusebius of Caesareas Vita Constantini, a work that is a mixture of eulogy and hagiography. Written between 335AD and circa 339AD, the Vita extols Constantines moral and religious virtues. The Vita creates a contentiously positive image of Constantine, and modern historians have frequently challenged its reliability. The fullest secular life of Constantine is the anonymous Origo Constantini. A work of uncertain date, the Origo focuses on military and political events, to the neglect of cultural and religious matters. Lactantius De Mortibus Persecutorum, a political Christian pamphlet on the reigns of Diocletian and the Tetrarchy, provides valuable but tendentious detail on Constantines predecessors and early life. The ecclesiastical histories of Socrates, Sozomen, and Theodoret describe the ecclesiastic disputes of Constantines later reign. Written during the reign of Theodosius II (408-50AD), a century after Constantines reign, these ecclesiastic historians obscure the events and theologies of the Constantinian period through misdirection, misrepresentation and deliberate obscurity. The contemporary writings of the orthodox Christian Athanasius and the ecclesiastical history of the Arian Philostorgius also survive, though their biases are no less firm. The epitomes of Aurelius Victor (De Caesaribus), Eutropius (Breviarium), Festus (Breviarium), and the anonymous author of the Epitome de Caesaribus offer compressed secular political and military histories of the period. Although not Christian, the epitomes paint a favorable image of Constantine, but omit reference to Constantines religious policies. The Panegyrici Latini, a collection of panegyrics from the late third and early fourth centuries, provide valuable information on the politics and ideology of the tetrarchic period and the early life of Constantine. Contemporary architecture, such as the Arch of Constantine in Rome and palaces in Gamzigrad and Córdoba, epigraphic remains, and the coinage of the era complement the literary sources. Early life
Remains of the luxurious residence palace of Mediana, erected by Constantine I near his birth town of Naissus
Flavius Valerius Constantinus, as he was originally named, was born in the city of Naissus, (today Niš, Serbia) part of the Dardania province of Moesia on 27 February, probably c. 272AD. His father was Flavius Constantius, an Illyrian, and a native of Dardania province of Moesia (later Dacia Ripensis). Constantine probably spent little time with his father who was an officer in the Roman army, part of the Emperor Aurelians imperial bodyguard. Being described as a tolerant and politically skilled man, Constantius advanced through the ranks, earning the governorship of Dalmatia from Emperor Diocletian, another of Aurelians companions from Illyricum, in 284 or 285. Constantines mother was Helena, possibly a Bithynian woman of low social standing. It is uncertain whether she was legally married to Constantius or merely his concubine. It is unclear if Constantine could speak Thracian, his main language being Latin, and during his public speeches he needed Greek translators.

In July 285AD, Diocletian declared Maximian, another colleague from Illyricum, his co-emperor. Each emperor would have his own court, his own military and administrative faculties, and each would rule with a separate praetorian prefect as chief lieutenant. Maximian ruled in the West, from his capitals at Mediolanum (Milan, Italy) or Augusta Treverorum (Trier, Germany), while Diocletian ruled in the East, from Nicomedia (İzmit, Turkey). The division was merely pragmatic: the Empire was called "indivisible" in official panegyric, and both emperors could move freely throughout the Empire. In 288, Maximian appointed Constantius to serve as his praetorian prefect in Gaul. Constantius left Helena to marry Maximians stepdaughter Theodora in 288 or 289. Diocletian divided the Empire again in 293AD, appointing two Caesars (junior emperors) to rule over further subdivisions of East and West. Each would be subordinate to their respective Augustus (senior emperor) but would act with supreme authority in his assigned lands. This system would later be called the Tetrarchy. Diocletians first appointee for the office of Caesar was Constantius; his second was Galerius, a native of Felix Romuliana. According to Lactantius, Galerius was a brutal, animalistic man. Although he shared the paganism of Romes aristocracy, he seemed to them an alien figure, a semi-barbarian. On 1 March, Constantius was promoted to the office of Caesar, and dispatched to Gaul to fight the rebels Carausius and Allectus. In spite of meritocratic overtones, the Tetrarchy retained vestiges of hereditary privilege, and Constantine became the prime candidate for future appointment as Caesar as soon as his father took the position. Constantine went to the court of Diocletian, where he lived as his fathers heir presumptive. In the East

Constantine received a formal education at Diocletians court, where he learned Latin literature, Greek, and philosophy. The cultural environment in Nicomedia was open, fluid and socially mobile, and Constantine could mix with intellectuals both pagan and Christian. He may have attended the lectures of Lactantius, a Christian scholar of Latin in the city. Because Diocletian did not completely trust Constantius-none of the Tetrarchs fully trusted their colleagues-Constantine was held as something of a hostage, a tool to ensure Constantiuss best behavior. Constantine was nonetheless a prominent member of the court: he fought for Diocletian and Galerius in Asia, and served in a variety of tribunates; he campaigned against barbarians on the Danube in 296AD, and fought the Persians under Diocletian in Syria (297AD) and under Galerius in Mesopotamia (298-299AD). By late 305AD, he had become a tribune of the first order, a tribunus ordinis primi. Constantine had returned to Nicomedia from the eastern front by the spring of 303AD, in time to witness the beginnings of Diocletians "Great Persecution", the most severe persecution of Christians in Roman history. In late 302, Diocletian and Galerius sent a messenger to the oracle of Apollo at Didyma with an inquiry about Christians. Constantine could recall his presence at the palace when the messenger returned, when Diocletian accepted his courts demands for universal persecution. On 23 February 303AD, Diocletian ordered the destruction of Nicomedias new church, condemned its scriptures to the flames, and had its treasures seized. In the months that followed, churches and scriptures were destroyed, Christians were deprived of official ranks, and priests were imprisoned. It is unlikely that Constantine played any role in the persecution. In his later writings he would attempt to present himself as an opponent of Diocletians "sanguinary edicts" against the "worshippers of God", but nothing indicates that he opposed it effectively at the time. Although no contemporary Christian challenged Constantine for his inaction during the persecutions, it remained a political liability throughout his life. On 1 May 305AD, Diocletian, as a result of a debilitating sickness taken in the winter of 304-305AD, announced his resignation. In a parallel ceremony in Milan, Maximian did the same. Lactantius states that Galerius manipulated the weakened Diocletian into resigning, and forced him to accept Galerius allies in the imperial succession. According to Lactantius, the crowd listening to Diocletians resignation speech believed, until the very last moment, that Diocletian would choose Constantine and Maxentius (Maximians son) as his successors. It was not to be: Constantius and Galerius were promoted to Augusti, while Severus and Maximinus Daia, Galerius nephew, were appointed their Caesars respectively. Constantine and Maxentius were ignored. Some of the ancient sources detail plots that Galerius made on Constantines life in the months following Diocletians abdication. They assert that Galerius assigned Constantine to lead an advance unit in a cavalry charge through a swamp on the middle Danube, made him enter into single combat with a lion, and attempted to kill him in hunts and wars. Constantine always emerged victorious: the lion emerged from the contest in a poorer condition than Constantine; Constantine returned to Nicomedia from the Danube with a Sarmatian captive to drop at Galerius feet. It is uncertain how much these tales can be trusted. In the WestConstantine recognized the implicit danger in remaining at Galeriuss court, where he was held as a virtual hostage. His career depended on being rescued by his father in the west. Constantius was quick to intervene. In the late spring or early summer of 305AD, Constantius requested leave for his son to help him campaign in Britain. After a long evening of drinking, Galerius granted the request. Constantines later propaganda describes how he fled the court in the night, before Galerius could change his mind. He rode from post-house to post-house at high speed, hamstringing every horse in his wake. By the time Galerius awoke the following morning, Constantine had fled too far to be caught. Constantine joined his father in Gaul, at Bononia (Boulogne) before the summer of 305AD.

From Bononia they crossed the Channel to Britain and made their way to Eboracum (York), capital of the province of Britannia Secunda and home to a large military base. Constantine was able to spend a year in northern Britain at his fathers side, campaigning against the Picts beyond Hadrians Wall in the summer and autumn. Constantiuss campaign, like that of Septimius Severus before it, probably advanced far into the north without achieving great success. Constantius had become severely sick over the course of his reign, and died on 25 July 306 in Eboracum (York). Before dying, he declared his support for raising Constantine to the rank of full Augustus. The Alamannic king Chrocus, a barbarian taken into service under Constantius, then proclaimed Constantine as Augustus. The troops loyal to Constantius memory followed him in acclamation. Gaul and Britain quickly accepted his rule; Iberia, which had been in his fathers domain for less than a year, rejected it. Constantine sent Galerius an official notice of Constantiuss death and his own acclamation. Along with the notice, he included a portrait of himself in the robes of an Augustus. The portrait was wreathed in bay. He requested recognition as heir to his fathers throne, and passed off responsibility for his unlawful ascension on his army, claiming they had "forced it upon him". Galerius was put into a fury by the message; he almost set the portrait on fire. His advisers calmed him, and argued that outright denial of Constantines claims would mean certain war. Galerius was compelled to compromise: he granted Constantine the title "Caesar" rather than "Augustus" (the latter office went to Severus instead). Wishing to make it clear that he alone gave Constantine legitimacy, Galerius personally sent Constantine the emperors traditional purple robes. Constantine accepted the decision, knowing that it would remove doubts as to his legitimacy. Early ruleConstantines share of the Empire consisted of Britain, Gaul, and Spain. He therefore commanded one of the largest Roman armies, stationed along the important Rhine frontier. After his promotion to emperor, Constantine remained in Britain, driving back the tribes of the Picts and secured his control in the northwestern dioceses. He completed the reconstruction of military bases begun under his fathers rule, and ordered the repair of the regions roadways. He soon left for Augusta Treverorum (Trier) in Gaul, the Tetrarchic capital of the northwestern Roman Empire. The Franks, after learning of Constantines acclamation, invaded Gaul across the lower Rhine over the winter of 306-307AD. Constantine drove them back beyond the Rhine and captured two of their kings, Ascaric and Merogaisus. The kings and their soldiers were fed to the beasts of Triers amphitheater in the adventus (arrival) celebrations that followed.
Public baths (thermae) built in Trier by Constantine. More than 100 metres (328ft) wide by 200 metres (656ft) long, and capable of serving several thousands at a time, the baths were built to rival those of Rome.
Constantine began a major expansion of Trier. He strengthened the circuit wall around the city with military towers and fortified gates, and began building a palace complex in the northeastern part of the city. To the south of his palace, he ordered the construction of a large formal audience hall, and a massive imperial bathhouse. Constantine sponsored many building projects across Gaul during his tenure as emperor of the West, especially in Augustodunum (Autun) and Arelate (Arles). According to Lactantius, Constantine followed his father in following a tolerant policy towards Christianity. Although not yet a Christian, he probably judged it a more sensible policy than open persecution, and a way to distinguish himself from the "great persecutor", Galerius. Constantine decreed a formal end to persecution, and returned to Christians all they had lost during the persecutions. Because Constantine was still largely untried and had a hint of illegitimacy about him, he relied on his fathers reputation in his early propaganda: the earliest panegyrics to Constantine give as much coverage to his fathers deeds as to those of Constantine himself. Constantines military skill and building projects soon gave the panegyrist the opportunity to comment favorably on the similarities between father and son, and Eusebius remarked that Constantine was a "renewal, as it were, in his own person, of his fathers life and reign". Constantinian coinage, sculpture and oratory also shows a new tendency for disdain towards the "barbarians" beyond the frontiers. After Constantines victory over the Alemanni, he minted a coin issue depicting weeping and begging Alemannic tribesmen-"The Alemanni conquered"-beneath the phrase "Romans rejoicing". There was little sympathy for these enemies. As his panegyrist declared: "It is a stupid clemency that spares the conquered foe." Maxentius rebellion
Dresden bust of Maxentius
Following Galerius recognition of Constantine as caesar, Constantines portrait was brought to Rome, as was customary. Maxentius mocked the portraits subject as the son of a harlot, and lamented his own powerlessness. Maxentius, envious of Constantines authority, seized the title of emperor on 28 October 306AD. Galerius refused to recognize him, but failed to unseat him. Galerius sent Severus against Maxentius, but during the campaign, Severus armies, previously under command of Maxentius father Maximian, defected, and Severus was seized and imprisoned. Maximian, brought out of retirement by his sons rebellion, left for Gaul to confer with Constantine in late 307AD. He offered to marry his daughter Fausta to Constantine, and elevate him to Augustan rank. In return, Constantine would reaffirm the old family alliance between Maximian and Constantius, and offer support to Maxentius cause in Italy. Constantine accepted, and married Fausta in Trier in late summer 307AD. Constantine now gave Maxentius his meagre support, offering Maxentius political recognition. Constantine remained aloof from the Italian conflict, however. Over the spring and summer of 307AD, he had left Gaul for Britain to avoid any involvement in the Italian turmoil; now, instead of giving Maxentius military aid, he sent his troops against Germanic tribes along the Rhine. In 308AD, he raided the territory of the Bructeri, and made a bridge across the Rhine at Colonia Agrippinensium (Cologne). In 310AD, he marched to the northern Rhine and fought the Franks. When not campaigning, he toured his lands advertising his benevolence, and supporting the economy and the arts. His refusal to participate in the war increased his popularity among his people, and strengthened his power base in the West. Maximian returned to Rome in the winter of 307-308AD, but soon fell out with his son. In early 308AD, after a failed attempt to usurp Maxentius title, Maximian returned to Constantines court. On 11 November 308AD, Galerius called a general council at the military city of Carnuntum (Petronell-Carnuntum, Austria) to resolve the instability in the western provinces. In attendance were Diocletian, briefly returned from retirement, Galerius, and Maximian. Maximian was forced to abdicate again and Constantine was again demoted to Caesar. Licinius, one of Galerius old military companions, was appointed Augustus in the western regions. The new system did not last long: Constantine refused to accept the demotion, and continued to style himself as Augustus on his coinage, even as other members of the Tetrarchy referred to him as a Caesar on theirs. Maximinus Daia was frustrated that he had been passed over for promotion while the newcomer Licinius had been raised to the office of Augustus, and demanded that Galerius promote him. Galerius offered to call both Maximinus and Constantine "sons of the Augusti", but neither accepted the new title. By the spring of 310AD, Galerius was referring to both men as Augusti. Maximians rebellionIn 310AD, a dispossessed Maximian rebelled against Constantine while Constantine was away campaigning against the Franks. Maximian had been sent south to Arles with a contingent of Constantines army, in preparation for any attacks by Maxentius in southern Gaul. He announced that Constantine was dead, and took up the imperial purple. In spite of a large donative pledge to any who would support him as emperor, most of Constantines army remained loyal to their emperor, and Maximian was soon compelled to leave. Constantine soon heard of the rebellion, abandoned his campaign against the Franks, and marched his army up the Rhine. At Cabillunum (Chalon-sur-Saône), he moved his troops onto waiting boats to row down the slow waters of the Saône to the quicker waters of the Rhone. He disembarked at Lugdunum (Lyon). Maximian fled to Massilia (Marseille), a town better able to withstand a long siege than Arles. It made little difference, however, as loyal citizens opened the rear gates to Constantine. Maximian was captured and reproved for his crimes. Constantine granted some clemency, but strongly encouraged his suicide. In July 310AD, Maximian hanged himself. In spite of the earlier rupture in their relations, Maxentius was eager to present himself as his fathers devoted son after his death. He began minting coins with his fathers deified image, proclaiming his desire to avenge Maximians death. Constantine initially presented the suicide as an unfortunate family tragedy. By 311AD, however, he was spreading another version. According to this, after Constantine had pardoned him, Maximian planned to murder Constantine in his sleep. Fausta learned of the plot and warned Constantine, who put a eunuch in his own place in bed. Maximian was apprehended when he killed the eunuch and was offered suicide, which he accepted. Along with using propaganda, Constantine instituted a damnatio memoriae on Maximian, destroying all inscriptions referring to him and eliminating any public work bearing his image. The death of Maximian required a shift in Constantines public image. He could no longer rely on his connection to the elder emperor Maximian, and needed a new source of legitimacy. In a speech delivered in Gaul on 25 July 310AD, the anonymous orator reveals a previously unknown dynastic connection to Claudius II, a 3rd Century emperor famed for defeating the Goths and restoring order to the empire. Breaking away from tetrarchic models, the speech emphasizes Constantines ancestral prerogative to rule, rather than principles of imperial equality. The new ideology expressed in the speech made Galerius and Maximian irrelevant to Constantines right to rule. Indeed, the orator emphasizes ancestry to the exclusion of all other factors: "No chance agreement of men, nor some unexpected consequence of favor, made you emperor," the orator declares to Constantine. The oration also moves away from the religious ideology of the Tetrarchy, with its focus on twin dynasties of Jupiter and Hercules. Instead, the orator proclaims that Constantine experienced a divine vision of Apollo and Victory granting him laurel wreaths of health and a long reign. In the likeness of Apollo Constantine recognized himself as the saving figure to whom would be granted "rule of the whole world", as the poet Virgil had once foretold. The orations religious shift is paralleled by a similar shift in Constantines coinage. In his early reign, the coinage of Constantine advertised Mars as his patron. From 310AD on, Mars was replaced by Sol Invictus, a god conventionally identified with Apollo. There is little reason to believe that either the dynastic connection or the divine vision are anything other than fiction, but their proclamation strengthened Constantines claims to legitimacy and increased his popularity among the citizens of Gaul. Civil warsSee also: Civil wars of the TetrarchyWar against MaxentiusBy the middle of 310AD, Galerius had become too ill to involve himself in imperial politics. His final act survives: a letter to the provincials posted in Nicomedia on 30 April 311AD, proclaiming an end to the persecutions, and the resumption of religious toleration. He died soon after the edicts proclamation, destroying what little remained of the tetrarchy. Maximinus mobilized against Licinius, and seized Asia Minor. A hasty peace was signed on a boat in the middle of the Bosphorus. While Constantine toured Britain and Gaul, Maxentius prepared for war. He fortified northern Italy, and strengthened his support in the Christian community by allowing it to elect a new Bishop of Rome, Eusebius. Maxentius rule was nevertheless insecure. His early support dissolved in the wake of heightened tax rates and depressed trade; riots broke out in Rome and Carthage; and Domitius Alexander was able to briefly usurp his authority in Africa. By 312AD, he was a man barely tolerated, not one actively supported, even among Christian Italians. In the summer of 311AD, Maxentius mobilized against Constantine while Licinius was occupied with affairs in the East. He declared war on Constantine, vowing to avenge his fathers "murder". To prevent Maxentius from forming an alliance against him with Licinius, Constantine forged his own alliance with Licinius over the winter of 311-312AD, and offered him his sister Constantia in marriage. Maximin considered Constantines arrangement with Licinius an affront to his authority. In response, he sent ambassadors to Rome, offering political recognition to Maxentius in exchange for a military support. Maxentius accepted. According to Eusebius, inter-regional travel became impossible, and there was military buildup everywhere. There was "not a place where people were not expecting the onset of hostilities every day". Constantines advisers and generals cautioned against preemptive attack on Maxentius; even his soothsayers recommended against it, stating that the sacrifices had produced unfavorable omens. Constantine, with a spirit that left a deep impression on his followers, inspiring some to believe that he had some form of supernatural guidance, ignored all these cautions. Early in the spring of 312AD, Constantine crossed the Cottian Alps with a quarter of his army, a force numbering about 40,000. The first town his army encountered was Segusium (Susa, Italy), a heavily fortified town that shut its gates to him. Constantine ordered his men to set fire to its gates and scale its walls. He took the town quickly. Constantine ordered his troops not to loot the town, and advanced with them into northern Italy. At the approach to the west of the important city of Augusta Taurinorum (Turin, Italy), Constantine met a large force of heavily armed Maxentian cavalry. In the ensuing battle Constantines army encircled Maxentius cavalry, flanked them with his own cavalry, and dismounted them with blows from his soldiers iron-tipped clubs. Constantines armies emerged victorious. Turin refused to give refuge to Maxentius retreating forces, opening its gates to Constantine instead. Other cities of the north Italian plain sent Constantine embassies of congratulation for his victory. He moved on to Milan, where he was met with open gates and jubilant rejoicing. Constantine rested his army in Milan until mid-summer 312AD, when he moved on to Brixia (Brescia). Brescias army was easily dispersed, and Constantine quickly advanced to Verona, where a large Maxentian force was camped. Ruricius Pompeianus, general of the Veronese forces and Maxentius praetorian prefect, was in a strong defensive position, since the town was surrounded on three sides by the Adige. Constantine sent a small force north of the town in an attempt to cross the river unnoticed. Ruricius sent a large detachment to counter Constantines expeditionary force, but was defeated. Constantines forces successfully surrounded the town and laid siege. Ruricius gave Constantine the slip and returned with a larger force to oppose Constantine. Constantine refused to let up on the siege, and sent only a small force to oppose him. In the desperately fought encounter that followed, Ruricius was killed and his army destroyed. Verona surrendered soon afterwards, followed by Aquileia, Mutina (Modena), and Ravenna. The road to Rome was now wide open to Constantine.
The Milvian Bridge (Ponte Milvio) over the Tiber, north of Rome, where Constantine and Maxentius fought in the Battle of the Milvian Bridge
Maxentius prepared for the same type of war he had waged against Severus and Galerius: he sat in Rome and prepared for a siege. He still controlled Romes praetorian guards, was well-stocked with African grain, and was surrounded on all sides by the seemingly impregnable Aurelian Walls. He ordered all bridges across the Tiber cut, reportedly on the counsel of the gods, and left the rest of central Italy undefended; Constantine secured that regions support without challenge. Constantine progressed slowly along the Via Flaminia, allowing the weakness of Maxentius to draw his regime further into turmoil. Maxentius support continued to weaken: at chariot races on 27 October, the crowd openly taunted Maxentius, shouting that Constantine was invincible. Maxentius, no longer certain that he would emerge from a siege victorious, built a temporary boat bridge across the Tiber in preparation for a field battle against Constantine. On 28 October 312AD, the sixth anniversary of his reign, he approached the keepers of the Sibylline Books for guidance. The keepers prophesied that, on that very day, "the enemy of the Romans" would die. Maxentius advanced north to meet Constantine in battle.

The Battle of the Milvian Bridge by Giulio Romano
Maxentius organized his forces-still twice the size of Constantines-in long lines facing the battle plain, with their backs to the river. Constantines army arrived at the field bearing unfamiliar symbols on either its standards or its soldiers shields. According to Lactantius, Constantine was visited by a dream the night before the battle, wherein he was advised "to mark the heavenly sign of God on the shields of his soldiers... by means of a slanted letter X with the top of its head bent round, he marked Christ on their shields." Eusebius describes another version, where, while marching at midday, "he saw with his own eyes in the heavens a trophy of the cross arising from the light of the sun, carrying the message, In Hoc Signo Vinces or "with this sign, you will conquer"; in Eusebiuss account, Constantine had a dream the following night, in which Christ appeared with the same heavenly sign, and told him to make a standard, the labarum, for his army in that form. Eusebius is vague about when and where these events took place, but it enters his narrative before the war against Maxentius begins. Eusebius describes the sign as Chi (Χ) traversed by Rho (Ρ): ☧, a symbol representing the first two letters of the Greek spelling of the word Christos or Christ. In 315AD a medallion was issued at Ticinum showing Constantine wearing a helmet emblazoned with the Chi Rho, and coins issued at Siscia in 317/318AD repeat the image. The figure was otherwise rare, however, and is uncommon in imperial iconography and propaganda before the 320s. Constantine deployed his own forces along the whole length of Maxentius line. He ordered his cavalry to charge, and they broke Maxentius cavalry. He then sent his infantry against Maxentius infantry, pushing many into the Tiber where they were slaughtered and drowned. The battle was brief: Maxentius troops were broken before the first charge. Maxentius horse guards and praetorians initially held their position, but broke under the force of a Constantinian cavalry charge; they also broke ranks and fled to the river. Maxentius rode with them, and attempted to cross the bridge of boats, but he was pushed by the mass of his fleeing soldiers into the Tiber, and drowned. In Rome
Colossal head of Constantine, from a seated statue: a youthful, classicising, other-worldly official image (Metropolitan Museum of Art)
Constantine entered Rome on 29 October 312. He staged a grand adventus in the city, and was met with popular jubilation. Maxentius body was fished out of the Tiber and decapitated. His head was paraded through the streets for all to see. After the ceremonies, Maxentius disembodied head was sent to Carthage; at this, Carthage would offer no further resistance. Unlike his predecessors, Constantine neglected to make the trip to the Capitoline Hill and perform customary sacrifices at the Temple of Jupiter. He did, however, choose to honor the Senatorial Curia with a visit, where he promised to restore its ancestral privileges and give it a secure role in his reformed government: there would be no revenge against Maxentius supporters. In response, the Senate decreed him "title of the first name", which meant his name would be listed first in all official documents, and acclaimed him as "the greatest Augustus". He issued decrees returning property lost under Maxentius, recalling political exiles, and releasing Maxentius imprisoned opponents. An extensive propaganda campaign followed, during which Maxentius image was systematically purged from all public places. Maxentius was written up as a "tyrant", and set against an idealized image of the "liberator", Constantine. Eusebius, in his later works, is the best representative of this strand of Constantinian propaganda. Maxentius rescripts were declared invalid, and the honors Maxentius had granted to leaders of the Senate were invalidated. Constantine also attempted to remove Maxentius influence on Romes urban landscape. All structures built by Maxentius were re-dedicated to Constantine, including the Temple of Romulus and the Basilica of Maxentius. At the focal point of the basilica, a stone statue of Constantine holding the Christian labarum in its hand was erected. Its inscription bore the message the statue had already made clear: By this sign Constantine had freed Rome from the yoke of the tyrant. Where he did not overwrite Maxentius achievements, Constantine upstaged them: the Circus Maximus was redeveloped so that its total seating capacity was twenty-five times larger than that of Maxentius racing complex on the Via Appia. Maxentius strongest supporters in the military were neutralized when the Praetorian Guard and Imperial Horse Guard (equites singulares) were disbanded. The tombstones of the Imperial Horse Guard were ground up and put to use in a basilica on the Via Labicana. On November 9, 312AD, barely two weeks after Constantine captured the city, the former base of the Imperial Horse Guard was chosen for redevelopment into the Lateran Basilica. The Legio II Parthica was removed from Alba (Albano Laziale), and the remainder of Maxentius armies were sent to do frontier duty on the Rhine. Wars against LiciniusIn the following years, Constantine gradually consolidated his military superiority over his rivals in the crumbling Tetrarchy. In 313, he met Licinius in Milan to secure their alliance by the marriage of Licinius and Constantines half-sister Constantia. During this meeting, the emperors agreed on the so-called Edict of Milan, officially granting full tolerance to Christianity and all religions in the Empire. The document had special benefits for Christians, legalizing their religion and granting them restoration for all property seized during Diocletians persecution. It repudiates past methods of religious coercion and used only general terms to refer to the divine sphere-"Divinity" and "Supreme Divinity", summa divinitas. The conference was cut short, however, when news reached Licinius that his rival Maximin had crossed the Bosporus and invaded European territory. Licinius departed and eventually defeated Maximin, gaining control over the entire eastern half of the Roman Empire. Relations between the two remaining emperors deteriorated, as Constantine suffered an assassination attempt at the hands of a character that Licinius wanted elevated to the rank of Caesar; Licinius, for his part had Constantines statues in Emona destroyed. In either 314 or 316 the two Augusti fought against one another at the Battle of Cibalae, with Constantine being victorious. They clashed again at the Battle of Mardia in 317, and agreed to a settlement in which Constantines sons Crispus and Constantine II, and Licinius son Licinianus were made caesars. After this arrangement, Constantine ruled the dioceses of Pannonia and Macedonia and took residence at Sirmium, whence he could wage war on the Goths and Sarmatians in 322, and on the Goths in 323. In the year 320, Licinius allegedly reneged on the religious freedom promised by the Edict of Milan in 313 and began to oppress Christians anew, generally without bloodshed, but resorting to confiscations and sacking of Christian office-holders. Although this characterization of Licinius as anti-Christian is somewhat doubtful, the fact is that he seems to have been far less open in his support of Christianity than Constantine. Therefore, Licinius was prone to see the Church as a force more loyal to Constantine than to the Imperial system in general - the explanation offered by the Church historian Sozomen. This dubious arrangement eventually became a challenge to Constantine in the West, climaxing in the great civil war of 324. Licinius, aided by Goth mercenaries, represented the past and the ancient Pagan faiths. Constantine and his Franks marched under the standard of the labarum, and both sides saw the battle in religious terms. Outnumbered, but fired by their zeal, Constantines army emerged victorious in the Battle of Adrianople. Licinius fled across the Bosphorus and appointed Martius Martinianus, the commander of his bodyguard, as Caesar, but Constantine next won the Battle of the Hellespont, and finally the Battle of Chrysopolis on 18 September 324. Licinius and Martinianus surrendered to Constantine at Nicomedia on the promise their lives would be spared: they were sent to live as private citizens in Thessalonica and Cappadocia respectively, but in 325 Constantine accused Licinius of plotting against him and had them both arrested and hanged; Liciniuss son (the son of Constantines half-sister) was also killed. Thus Constantine became the sole emperor of the Roman Empire. Later ruleFoundation of Constantinople
Coin struck by Constantine I to commemorate the founding of Constantinople Licinius defeat came to represent the defeat of a rival center of Pagan and Greek-speaking political activity in the East, as opposed to the Christian and Latin-speaking Rome, and it was proposed that a new Eastern capital should represent the integration of the East into the Roman Empire as a whole, as a center of learning, prosperity, and cultural preservation for the whole of the Eastern Roman Empire. Among the various locations proposed for this alternative capital, Constantine appears to have toyed earlier with Serdica (present-day Sofia), as he was reported saying that "Serdica is my Rome". Sirmium and Thessalonica were also considered. Eventually, however, Constantine decided to work on the Greek city of Byzantium, which offered the advantage of having already been extensively rebuilt on Roman patterns of urbanism, during the preceding century, by Septimius Severus and Caracalla, who had already acknowledged its strategic importance. The city was thus founded in 324, dedicated on 11 May 330 and renamed Constantinopolis ("Constantines City" or Constantinople in English). Special commemorative coins were issued in 330 to honor the event. The new city was protected by the relics of the True Cross, the Rod of Moses and other holy relics, though a cameo now at the Hermitage Museum also represented Constantine crowned by the tyche of the new city. The figures of old gods were either replaced or assimilated into a framework of Christian symbolism. Constantine built the new Church of the Holy Apostles on the site of a temple to Aphrodite. Generations later there was the story that a divine vision led Constantine to this spot, and an angel no one else could see, led him on a circuit of the new walls. The capital would often be compared to the old Rome as Nova Roma Constantinopolitana, the "New Rome of Constantinople". Religious policyFurther information: Constantine I and Christianity, Constantine I and paganism, and Constantine the Great and Judaism
Constantine the Great, mosaic in Hagia Sophia, c. 1000
Constantine was the first emperor to stop Christian persecutions and to legalise Christianity along with all other religions and cults in the Roman Empire. In February 313, Constantine met with Licinius in Milan, where they developed the Edict of Milan. The edict stated that Christians should be allowed to follow the faith without oppression. This removed penalties for professing Christianity, under which many had been martyred previously, and returned confiscated Church property. The edict protected from religious persecution not only Christians but all religions, allowing anyone to worship whichever deity they chose. A similar edict had been issued in 311 by Galerius, then senior emperor of the Tetrarchy; Galerius edict granted Christians the right to practise their religion but did not restore any property to them. The Edict of Milan included several clauses which stated that all confiscated churches would be returned as well as other provisions for previously persecuted Christians. Scholars debate whether Constantine adopted his mother St. Helenas Christianity in his youth, or whether he adopted it gradually over the course of his life. Constantine possibly retained the title of pontifex maximus, a title emperors bore as heads of the ancient Roman religion priesthood until Gratian (r. 375-383) renounced the title. According to Christian writers, Constantine was over 40 when he finally declared himself a Christian, writing to Christians to make clear that he believed he owed his successes to the protection of the Christian High God alone. Throughout his rule, Constantine supported the Church financially, built basilicas, granted privileges to clergy (e.g. exemption from certain taxes), promoted Christians to high office, and returned property confiscated during the Diocletianic persecution. His most famous building projects include the Church of the Holy Sepulchre, and Old Saint Peters Basilica. Apparently Constantine did not patronize Christianity alone. After gaining victory in the Battle of the Milvian Bridge (312), a triumphal arch-the Arch of Constantine-was built (315) to celebrate his triumph. The arch is decorated with images of the goddess Victoria. At the time of its dedication, sacrifices to gods like Apollo, Diana, and Hercules were made. Absent from the Arch are any depictions of Christian symbolism. However, as the Arch was commissioned by the Senate, the absence of Christian symbols may reflect the role of the Curia at the time as a pagan redoubt. In 321, he legislated that the venerable day of the sun should be a day of rest for all citizens. In the year 323, he issued a decree banning Christians from participating in state sacrifices Furthermore, Constantines coinage continued to carry the symbols of the sun. After the pagan gods had disappeared from his coinage, Christian symbols appeared as Constantines attributes: the chi rho between his hands or on his labarum, as well on the coin itself. The reign of Constantine established a precedent for the position of the emperor as having great influence and ultimate regulatory authority within the religious discussions involving the early Christian councils of that time, e.g., most notably the dispute over Arianism. Constantine himself disliked the risks to societal stability that religious disputes and controversies brought with them, preferring where possible to establish an orthodoxy. His influence over the early Church councils was to enforce doctrine, root out heresy, and uphold ecclesiastical unity; what proper worship and doctrines and dogma consisted of was for the Church to determine, in the hands of the participating bishops. Most notably, from 313 to 316 bishops in North Africa struggled with other Christian bishops who had been ordained by Donatus in opposition to Caecilian. The African bishops could not come to terms and the Donatists asked Constantine to act as a judge in the dispute. Three regional Church councils and another trial before Constantine all ruled against Donatus and the Donatism movement in North Africa. In 317 Constantine issued an edict to confiscate Donatist church property and to send Donatist clergy into exile. More significantly, in 325 he summoned the Council of Nicaea, effectively the first Ecumenical Council (unless the Council of Jerusalem is so classified), most known for its dealing with Arianism and for instituting the Nicene Creed. Constantine enforced the prohibition of the First Council of Nicaea against celebrating the Lords Supper on the day before the Jewish Passover (14 Nisan) (see Quartodecimanism and Easter controversy). This marked a definite break of Christianity from the Judaic tradition. From then on the Roman Julian Calendar, a solar calendar, was given precedence over the lunisolar Hebrew Calendar among the Christian churches of the Roman Empire. Constantine made some new laws regarding the Jews, but while some of his edicts were unfavorable towards Jews, they were not harsher than those of his predecessors. It was made illegal for Jews to seek converts or to attack other Jews who had converted to Christianity. They were forbidden to own Christian slaves or to circumcise their slaves. On the other hand, Jewish clergy were given the same exemptions as Christian clergy. Administrative reforms

Beginning in the mid-3rd century the emperors began to favor members of the equestrian order over senators, who had had a monopoly on the most important offices of state. Senators were stripped of the command of legions and most provincial governorships (as it was felt that they lacked the specialized military upbringing needed in an age of acute defense needs), such posts being given to equestrians by Diocletian and his colleagues-following a practice enforced piecemeal by their predecessors. The emperors, however, still needed the talents and the help of the very rich, who were relied on to maintain social order and cohesion by means of a web of powerful influence and contacts at all levels. Exclusion of the old senatorial aristocracy threatened this arrangement. In 326, Constantine reversed this pro-equestrian trend, raising many administrative positions to senatorial rank and thus opening these offices to the old aristocracy, and at the same time elevating the rank of already existing equestrians office-holders to senator, degrading the equestrian order -at least as a bureaucratic rank -in the process, so that by the end of the 4th century the title of perfectissimus was granted only to mid-low officials. By the new Constantinian arrangement, one could become a senator, either by being elected praetor or (in most cases) by fulfilling a function of senatorial rank: from then on, holding of actual power and social status were melded together into a joint imperial hierarchy. At the same time, Constantine gained with this the support of the old nobility, as the Senate was allowed itself to elect praetors and quaestors, in place of the usual practice of the emperors directly creating new magistrates (adlectio). In one inscription in honor of city prefect (336-337) Ceionius Rufus Albinus, it was written that Constantine had restored the Senate "the auctoritas it had lost at Caesars time". The Senate as a body remained devoid of any significant power; nevertheless, the senators, who had been marginalized as potential holders of imperial functions during the 3rd century, could now dispute such positions alongside more upstart bureaucrats. Some modern historians see in those administrative reforms an attempt by Constantine at reintegrating the senatorial order into the imperial administrative elite to counter the possibility of alienating pagan senators from a Christianized imperial rule; however, such an interpretation remains conjectural, given the fact that we do not have the precise numbers about pre-Constantine conversions to Christianity in the old senatorial milieu-some historians suggesting that early conversions among the old aristocracy were more numerous than previously supposed. Constantines reforms had to do only with the civilian administration: the military chiefs, who since the Crisis of the Third Century had risen from the ranks, remained outside the senate, in which they were included only by Constantines children. Monetary reformsAfter the runaway inflation of the third century, associated with the production of fiat money to pay for public expenses, Diocletian had tried unsuccessfully to re establish trustworthy minting of silver and billon coins. The failure of the various Diocletianic attempts at the restoration of a functioning silver coin resided in the fact that the silver currency was overvalued in terms of its actual metal content, and therefore could only circulate at much discounted rates. Minting of the Diocletianic "pure" silver argenteus ceased, therefore, soon after 305, while the billon currency continued to be used until the 360s. From the early 300s on, Constantine forsook any attempts at restoring the silver currency, preferring instead to concentrate on minting large quantities of good standard gold pieces-the solidus, 72 of which made a pound of gold. New (and highly debased) silver pieces would continue to be issued during Constantines later reign and after his death, in a continuous process of retariffing, until this bullion minting eventually ceased, de jure, in 367, with the silver piece being de facto continued by various denominations of bronze coins, the most important being the centenionalis. These bronze pieces continued to be devalued, assuring the possibility of keeping fiduciary minting alongside a gold standard. The anonymous author of the possibly contemporary treatise on military affairs De Rebus Bellicis held that, as a consequence of this monetary policy, the rift between classes widened: the rich benefited from the stability in purchasing power of the gold piece, while the poor had to cope with ever-degrading bronze pieces. Later emperors like Julian the Apostate tried to present themselves as advocates of the humiles by insisting on trustworthy mintings of the bronze currency. Constantines monetary policy were closely associated with his religious ones, in that increased minting was associated with measures of confiscation-taken since 331 and closed in 336-of all gold, silver and bronze statues from pagan temples, who were declared as imperial property and, as such, as monetary assets. Two imperial commissioners for each province had the task of getting hold of the statues and having them melded for immediate minting-with the exception of a number of bronze statues who were used as public monuments for the beautification of the new capital in Constantinople. Executions of Crispus and FaustaOn some date between 15 May and 17 June 326, Constantine had his eldest son Crispus, by Minervina, seized and put to death by "cold poison" at Pola (Pula, Croatia). In July, Constantine had his wife, the Empress Fausta, killed in an over-heated bath. Their names were wiped from the face of many inscriptions, references to their lives in the literary record were erased, and the memory of both was condemned. Eusebius, for example, edited praise of Crispus out of later copies of his Historia Ecclesiastica, and his Vita Constantini contains no mention of Fausta or Crispus at all. Few ancient sources are willing to discuss possible motives for the events; those few that do, offer unconvincing rationales, are of later provenance, and are generally unreliable. At the time of the executions, it was commonly believed that the Empress Fausta was either in an illicit relationship with Crispus, or was spreading rumors to that effect. A popular myth arose, modified to allude to Hippolytus-Phaedra legend, with the suggestion that Constantine killed Crispus and Fausta for their immoralities. One source, the largely fictional Passion of Artemius, probably penned in the eighth century by John of Damascus, makes the legendary connection explicit. As an interpretation of the executions, the myth rests on only "the slimmest of evidence": sources that allude to the relationship between Crispus and Fausta are late and unreliable, and the modern suggestion that Constantines "godly" edicts of 326 and the irregularities of Crispus are somehow connected rests on no evidence at all. Although Constantine created his apparent heirs "Caesars", following a pattern established by Diocletian, he gave his creations a hereditary character, alien to the tetrarchic system: Constantines Caesars were to be kept in the hope of ascending to Empire, and entirely subordinated to their Augustus, as long as he was alive. Therefore, an alternative explanation for the execution of Crispus was, perhaps, Constantines desire to keep a firm grip on his prospective heirs, this-and Faustas desire for having her sons inheriting instead of their half-brother-being reason enough for killing Crispus; the subsequent execution of Fausta, however, was probably meant as a reminder to her children that Constantine would not hesitate in "killing his own relatives when he felt this was necessary". Later campaigns

Constantine considered Constantinople his capital and permanent residence. He lived there for a good portion of his later life. He rebuilt Trajans bridge across the Danube, in hopes of reconquering Dacia, a province that had been abandoned under Aurelian. In the late winter of 332, Constantine campaigned with the Sarmatians against the Goths. The weather and lack of food cost the Goths dearly: reportedly, nearly one hundred thousand died before they submitted to Rome. In 334, after Sarmatian commoners had overthrown their leaders, Constantine led a campaign against the tribe. He won a victory in the war and extended his control over the region, as remains of camps and fortifications in the region indicate. Constantine resettled some Sarmatian exiles as farmers in Illyrian and Roman districts, and conscripted the rest into the army. Constantine took the title Dacicus maximus in 336. In the last years of his life Constantine made plans for a campaign against Persia. In a letter written to the king of Persia, Shapur, Constantine had asserted his patronage over Persias Christian subjects and urged Shapur to treat them well. The letter is undatable. In response to border raids, Constantine sent Constantius to guard the eastern frontier in 335. In 336, prince Narseh invaded Armenia (a Christian kingdom since 301) and installed a Persian clien" />
