Crises of the Roman Empire
The Crisis of the Third Century was a period in which the Roman Empire nearly collapsed under the combined pressures of invasion, civil war, plague, and economic depression.
Describe the problems afflicting the Roman Empire during the third century
- The situation of the Roman Empire became dire in 235 CE, when emperor Alexander Severus was murdered by his own troops after defeat by Germanic tribes.
- In the years following the emperor's death, generals of the Roman army fought each other for control of the Empire, and neglected their duties of defending the empire from invasion. As a result, various provinces became victims of frequent raids.
- By 268, the Empire had split into three competing states: the Gallic Empire, including the Roman provinces of Gaul, Britannia, and Hispania; the Palmyrene Empire, including the eastern provinces of Syria Palaestina and Aegyptus; and the Italian-centered and independent Roman Empire proper.
- One of the most profound and lasting effects of the Crisis of the Third Century was the disruption of Rome 's extensive internal trade network under the Pax Romana.

The Crisis of the Third Century, also known as Military Anarchy or the Imperial Crisis, (235-284 CE) was a period in which the Roman Empire nearly collapsed under the combined pressures of invasion, civil war, plague, and economic depression. The Crisis began with the assassination of Emperor Severus Alexander by his own troops in 235, initiating a 50-year period in which there were at least 26 claimants to the title of Emperor, mostly prominent Roman army generals, who assumed imperial power over all or part of the Empire. Twenty-six men were officially accepted by the Roman Senate as emperor during this period, and thus became legitimate emperors.
By 268, the Empire had split into three competing states: the Gallic Empire, including the Roman provinces of Gaul, Britannia, and (briefly) Hispania; the Palmyrene Empire, including the eastern provinces of Syria Palaestina and Aegyptus; and the Italian-centered and independent Roman Empire proper, between them. Later, Aurelian (270-275) reunited the empire; the Crisis ended with the ascension and reforms of Diocletian in 284.
The Crisis resulted in such profound changes in the Empire's institutions, society, economic life, and, eventually, religion, that it is increasingly seen by most historians as defining the transition between the historical periods of classical antiquity and late antiquity.

History of the Crisis
The situation of the Roman Empire became dire in 235 CE, when Emperor Alexander Severus was murdered by his own troops. Many Roman legions had been defeated during a campaign against Germanic peoples raiding across the borders, while the emperor was focused primarily on the dangers from the Sassanid Persian Empire. Leading his troops personally, Alexander Severus resorted to diplomacy and paying tribute, in an attempt to pacify the Germanic chieftains quickly. According to Herodian, this cost him the respect of his troops, who may have felt they should be punishing the tribes who were intruding on Rome's territory.
In the years following the emperor's death, generals of the Roman army fought each other for control of the Empire and neglected their duties of defending the empire from invasion. Provincials became victims of frequent raids along the length of the Rhine and Danube rivers, by such foreign tribes as the Carpians, Goths, Vandals, and Alamanni, and attacks from Sassanids in the east. Climate changes and a rise in sea levels ruined the agriculture of what is now the Low Countries, forcing tribes to migrate. Additionally, in 251, the Plague of Cyprian (possibly smallpox) broke out, causing large-scale death, and possibly weakened the ability of the Empire to defend itself.
After the loss of Valerian in 260, the Roman Empire was beset by usurpers, who broke it up into three competing states. The Roman provinces of Gaul, Britain, and Hispania broke off to form the Gallic Empire. After the death of Odaenathus in 267, the eastern provinces of Syria, Palestine, and Aegyptus became independent as the Palmyrene Empire, leaving the remaining Italian-centered Roman Empire proper in the middle.
An invasion by a vast host of Goths was defeated at the Battle of Naissus in 268 or 269. This victory was significant as the turning point of the crisis, when a series of tough, energetic soldier-emperors took power. Victories by Emperor Claudius II Gothicus over the next two years drove back the Alamanni and recovered Hispania from the Gallic Empire. When Claudius died in 270 of the plague, Aurelian, who had commanded the cavalry at Naissus, succeeded him as the emperor and continued the restoration of the Empire.
Aurelian reigned (270-275) through the worst of the crisis, defeating the Vandals, the Visigoths, the Palmyrenes, the Persians, and then the remainder of the Gallic Empire. By late 274, the Roman Empire was reunited into a single entity, and the frontier troops were back in place. More than a century would pass before Rome again lost military ascendancy over its external enemies. However, dozens of formerly thriving cities, especially in the Western Empire, had been ruined, their populations dispersed and, with the breakdown of the economic system, could not be rebuilt. Major cities and towns, even Rome itself, had not needed fortifications for many centuries; many then surrounded themselves with thick walls.
Finally, although Aurelian had played a significant role in restoring the Empire's borders from external threat, more fundamental problems remained. In particular, the right of succession had never been clearly defined in the Roman Empire, leading to continuous civil wars as competing factions in the military, Senate, and other parties put forward their favored candidate for emperor. Another issue was the sheer size of the Empire, which made it difficult for a single autocratic ruler to effectively manage multiple threats at the same time. These continuing problems would be radically addressed by Diocletian, allowing the Empire to continue to survive in the West for over a century, and in the East for over a millennium.
One of the most profound and lasting effects of the Crisis of the Third Century was the disruption of Rome's extensive internal trade network. Ever since the Pax Romana, starting with Augustus, the Empire's economy had depended in large part on trade between Mediterranean ports and across the extensive road systems to the Empire's interior. Merchants could travel from one end of the Empire to the other in relative safety within a few weeks, moving agricultural goods produced in the provinces to the cities, and manufactured goods produced by the great cities of the East to the more rural provinces.
With the onset of the Crisis of the Third Century, however, this vast internal trade network broke down. The widespread civil unrest made it no longer safe for merchants to travel as they once had, and the financial crisis that struck made exchange very difficult with the debased currency. This produced profound changes that, in many ways, foreshadowed the very decentralized economic character of the coming Middle Ages.
Large landowners, no longer able to successfully export their crops over long distances, began producing food for subsistence and local barter. Rather than import manufactured goods from the Empire's great urban areas, they began to manufacture many goods locally, often on their own estates, thus beginning the self-sufficient "house economy" that would become commonplace in later centuries, reaching its final form in the Middle Ages' manorialism. The common free people of the Roman cities, meanwhile, began to move out into the countryside in search of food and better protection.
Made desperate by economic necessity, many of these former city dwellers, as well as many small farmers, were forced to give up hard-earned, basic civil rights in order to receive protection from large land-holders. In doing so, they became a half-free class of Roman citizen known as coloni
. They were tied to the land, and in later Imperial law their status was made hereditary. This provided an early model for serfdom, the origins of medieval feudal society and of the medieval peasantry.
Diocletian and the Tetrarchy
Facing the pressures of civil war, plague, invasion, and economic depression, Diocletian was able to stabilize the Roman Empire for another hundred years through economic reform and the establishment of the Tetrarchy.
Describe the change in attitudes towards Christians and their statuses within the Roman Empire
- Diocletian secured the empire's borders and purged it of all threats to his power. He separated and enlarged the empire's civil and military services, and reorganized the empire's provincial divisions, establishing the largest and most bureaucratic government in the history of the empire.
- Diocletian also restructured the Roman government by establishing the Tetrarchy, a system of rule in which four men shared rule over the massive Roman Empire. The empire was effectively divided in two, with an Augustus and a subordinate Caesar in each half.
- Diocletian established administrative capitals for each of the Tetrarchs, which were located closer to the empire's borders. Though Rome retained its unique Prefect of the City, it was no longer the administrative capital.
- By 313, therefore, there remained only two emperors: Constantine in the west and Licinius in the east. The tetrarchic system was at an end, although it took until 324 for Constantine to finally defeat Licinius, reunite the two halves of the Roman Empire, and declare himself sole Augustus.
- Diocletian: Roman emperor from 284 to 305 CE. Established the tetrarchy and instituted economic and tax reforms to stabilize the Roman Empire.
- tetrarchy: A form of government in which power is divided between four individuals. In ancient Rome, a system of government instituted by Diocletian that split power between two rulers in the east, and two rulers in the west.
Diocletian and the Stabilization of the Roman Empire
Diocletian was Roman emperor from 284 to 305 CE. Born to a family of low status in the Roman province of Dalmatia, Diocletian rose through the ranks of the military to become cavalry commander to the Emperor Carus. After the deaths of Carus and his son Numerian on campaign in Persia, Diocletian was proclaimed emperor. Diocletian's reign stabilized the empire, and marked the end of the Crisis of the Third Century. He appointed fellow officer, Maximian, as Augustus, co-emperor, in 286. Diocletian delegated further in 293, appointing Galerius and Constantius as caesars, junior co-emperors. Under this "tetrarchy," or "rule of four," each emperor would rule over a quarter-division of the empire. Diocletian further secured the empire's borders and purged it of all threats to his power.
He separated and enlarged the empire's civil and military services and reorganized the empire's provincial divisions, establishing the largest and most bureaucratic government in the history of the empire. He established new administrative centers in Nicomedia, Mediolanum, Antioch, and Trier, closer to the empire's frontiers than the traditional capital at Rome had been. Building on third-century trends towards absolutism, he styled himself an autocrat, elevating himself above the empire's masses with imposing forms of court ceremonies and architecture. Bureaucratic and military growth, constant campaigning, and construction projects increased the state's expenditures and necessitated a comprehensive tax reform. From at least 297 on, imperial taxation was standardized, made more equitable, and levied at generally higher rates.

While it is referred to as a "palace" because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
The first phase of Diocletian's government restructuring, sometimes referred to as the diarchy ("rule of two"), involved the designation of the general Maximian as co-emperor—first as Caesar (junior emperor) in 285, then Augustus in 286. This reorganization allowed Diocletian to take care of matters in the eastern regions of the empire, while Maximian similarly took charge of the western regions, thereby halving the administrative work required to oversee an empire as large as Rome's. In 293, feeling more focus was needed on both civic and military problems, Diocletian, with Maximian's consent, expanded the imperial college by appointing two Caesars (one responsible to each Augustus)—Galerius and Constantius Chlorus.
In 305, the senior emperors jointly abdicated and retired, allowing Constantius and Galerius to be elevated in rank to Augusti. They in turn appointed two new Caesars—Severus II in the west under Constantius, and Maximinus in the east under Galerius—thereby creating the second tetrarchy.
The four tetrarchs based themselves not at Rome but in other cities closer to the frontiers, mainly intended as headquarters for the defense of the empire against bordering rivals. Although Rome ceased to be an operational capital, it continued to be the nominal capital of the entire Roman Empire, not reduced to the status of a province, but under its own, unique Prefect of the City (praefectus urbis
Zones of Influence in the Roman Tetrarchy:
This map shows the four zones of influence under Diocletian's tetrarchy.
In terms of regional jurisdiction, there was no precise division between the four tetrarchs, and this period did not see the Roman state actually split up into four distinct sub-empires. Each emperor had his zone of influence within the Roman Empire, but this influence mainly applied to the theater of war. The tetrarch was himself often in the field, while delegating most of the administration to the hierarchic bureaucracy headed by his respective Praetorian Prefect. The Praetorian Prefect was the title of a high office in the Roman Empire, originating as the commander of the Praetorian Guard, the office gradually acquired extensive legal and administrative functions, with its holders becoming the emperor's chief aides.
Demise of the Tetrarchy
When, in 305, the 20-year term of Diocletian and Maximian ended, both abdicated. Their Caesares, Galerius and Constantius Chlorus, were both raised to the rank of Augustus, and two new Caesares were appointed: Maximinus (Caesar to Galerius) and Flavius Valerius Severus (Caesar to Constantius). These four formed the second tetrarchy.
However, the system broke down very quickly thereafter. When Constantius died in 306, Galerius promoted Severus to Augustus while Constantine, Constantius' son, was proclaimed Augustus by his father's troops. At the same time, Maxentius, the son of Maximian, who also resented being left out of the new arrangements, defeated Severus before forcing him to abdicate and then arranging his murder in 307. Maxentius and Maximian both then declared themselves Augusti. By 308, there were therefore no fewer than four claimants to the rank of Augustus (Galerius, Constantine, Maximian and Maxentius), and only one to that of Caesar (Maximinus).
In 308, Galerius, together with the retired emperor Diocletian and the supposedly retired Maximian, called an imperial "conference" at Carnuntum on the River Danube. The council agreed that Licinius would become Augustus in the West, with Constantine as his Caesar. In the East, Galerius remained Augustus, and Maximinus remained his Caesar. Maximian was to retire, and Maxentius was declared an usurper. This agreement proved disastrous: by 308 Maxentius had become de facto ruler of Italy and Africa even without any imperial rank, and neither Constantine nor Maximinus—who had both been Caesares since 306 and 305, respectively—were prepared to tolerate the promotion of the Augustus Licinius as their superior.
After an abortive attempt to placate both Constantine and Maximinus with the meaningless title filius Augusti
("son of the Augustus," essentially an alternative title for Caesar), they both had to be recognized as Augusti in 309. However, four full Augusti all at odds with each other did not bode well for the tetrarchic system.
Between 309 and 313, most of the claimants to the imperial office died or were killed in various civil wars. Constantine forced Maximian's suicide in 310. Galerius died naturally in 311. Maxentius was defeated by Constantine at the Battle of the Milvian Bridge in 312, and subsequently killed. Maximinus committed suicide at Tarsus in 313, after being defeated in battle by Licinius.
By 313, therefore, there remained only two emperors: Constantine in the west and Licinius in the east. The tetrarchic system was at an end, although it took until 324 for Constantine to finally defeat Licinius, reunite the two halves of the Roman Empire, and declare himself sole Augustus.
The Rise of Christianity
Though the early Christians were persecuted under some emperors, such as Nero and Diocletian, the religion continued to thrive and grow, eventually becoming the official religion of the Roman Empire under Constantine.
Describe the challenges Christians faced in the Roman Empire
- Christians suffered from sporadic and localized persecutions over a period of two and a half centuries, as their refusal to participate in Imperial Cult of Rome was considered an act of treason, and was thus punishable by execution.
- The Diocletianic, or Great Persecution, was the last and most severe persecution of Christians in the Roman Empire, which lasted from 302-311 CE. Galerius issued an edict of toleration in 311, which granted Christians the right to practice their religion, but did not restore any taken property back to them.
- The Edict of Milan in 313 made the empire officially neutral with regard to religious worship; it neither made the traditional religions illegal nor made Christianity the state religion.
- the Great Persecution: The last and most severe persecution of Christians in the Roman Empire.
- Edict of Milan: An agreement in 313 CE by Constantine and Licinius to treat Christians benevolently within the Roman Empire.
Persecution of Early Christians
Christianity posed a serious threat to the traditional Romans. The idea of monotheism was considered offensive against the polytheistic Roman pantheon, and came into further conflict with the Imperial Cult, in which emperors and some members of their families were worshipped as divine. As such, Christianity was considered criminal and was punished harshly.
The first recorded official persecution of Christians on behalf of the Roman Empire was in 64 CE, when, as reported by the Roman historian Tacitus, Emperor Nero blamed Christians for the Great Fire of Rome. According to Church tradition, it was during the reign of Nero that Peter and Paul were martyred in Rome. However, modern historians debate whether the Roman government distinguished between Christians and Jews prior to Nerva's modification of the Fiscus Judaicus in 96, from which point practicing Jews paid the tax and Christians did not.
The Diocletianic or Great Persecution was the last and most severe persecution of Christians in the Roman Empire, which lasted from 302-311 CE. In 303, the emperors Diocletian, Maximian, Galerius, and Constantius issued a series of edicts rescinding the legal rights of Christians and demanding that they comply with traditional Roman religious practices. Later edicts targeted the clergy and ordered all inhabitants to sacrifice to the Roman gods (a policy known as universal sacrifice). The persecution varied in intensity across the empire—it was weakest in Gaul and Britain, where only the first edict was applied, and strongest in the Eastern provinces. Persecutory laws were nullified by different emperors at different times, but Constantine and Licinius's Edict of Milan (313) has traditionally marked the end of the persecution.
During the Great Persecution, Diocletian ordered Christian buildings and the homes of Christians torn down, and their sacred books collected and burned during the Great Persecution. Christians were arrested, tortured, mutilated, burned, starved, and condemned to gladiatorial contests to amuse spectators. The Great Persecution officially ended in April of 311, when Galerius, senior emperor of the Tetrarchy, issued an edict of toleration which granted Christians the right to practice their religion, though it did not restore any property to them. Constantine, Caesar in the western empire, and Licinius, Caesar in the east, also were signatories to the edict of toleration. It has been speculated that Galerius' reversal of his long-standing policy of Christian persecution has been attributable to one or both of these co-Caesars.
The Rise of Christianity
The Diocletianic persecution was ultimately unsuccessful. As one modern historian has put it, it was simply "too little and too late." Christians were never purged systematically in any part of the empire, and Christian evasion continually undermined the edicts' enforcement. Although the persecution resulted in death, torture, imprisonment, or dislocation for many Christians, the majority of the empire's Christians avoided punishment. Some bribed their way to freedom or fled. In the end, the persecution failed to check the rise of the church. By 324, Constantine was sole ruler of the empire, and Christianity had become his favored religion.
By 324, Constantine, the Christian convert, ruled the entire empire alone. Christianity became the greatest beneficiary of imperial largesse. The persecutors had been routed. As the historian J. Liebeschuetz has written: "The final result of the Great Persecution provided a testimonial to the truth of Christianity, which it could have won in no other way." After Constantine, the Christianization of the Roman empire would continue apace. Under Theodosius I (r. 378-395), Christianity became the state religion. By the 5th century, Christianity was the empire's predominant faith, and filled the same role paganism had at the end of the 3rd century. Because of the persecution, however, a number of Christian communities were riven between those who had complied with imperial authorities (traditores
) and those who had refused. In Africa, the Donatists, who protested the election of the alleged traditor, Caecilian, to the bishopric of Carthage, continued to resist the authority of the central church until after 411. The Melitians in Egypt left the Egyptian Church similarly divided.
The Edict of Milan
In 313, Constantine and Licinius announced in the Edict of Milan "that it was proper that the Christians and all others should have liberty to follow that mode of religion which to each of them appeared best," thereby granting tolerance to all religions, including Christianity. The Edict of Milan went a step further than the earlier Edict of Toleration by Galerius in 311, and returned confiscated Church property. This edict made the empire officially neutral with regard to religious worship; it neither made the traditional religions illegal, nor made Christianity the state religion (as did the later Edict of Thessalonica in 380 CE). The Edict of Milan did, however, raise the stock of Christianity within the empire, and it reaffirmed the importance of religious worship to the welfare of the state.
Constantine the Great was a Roman Emperor from 306 to 337 CE; he adopted Christianity and declared it the religion of the Roman Empire.

Constantine the Great was a Roman Emperor from 306-337 CE. 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 293 CE. 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 (modern Great Britain). Acclaimed as emperor by the army at Eboracum (modern-day York) after his father's death in 306 CE, 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 324 CE.
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. As 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 reorganized 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.
Constantine's reputation flourished during the lifetime of his children and for 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. One of his major political legacies, aside from moving the capital of the empire to Constantinople, was that, in leaving the empire to his sons, he replaced Diocletian's tetrarchy with the principle of dynastic succession.
The Battle of the Milvian Bridge
Eusebius of Caesarea, and other Christian sources, record that Constantine experienced a dramatic event in 312 at the Battle of the Milvian Bridge, after which Constantine claimed the emperorship in the west, and converted to Christianity. The Battle of the Milvian Bridge took place between the Roman Emperors, Constantine I and Maxentius, on October 28, 312. It takes its name from the Milvian Bridge, an important route over the Tiber. Constantine won the battle and started on the path that led him to end the tetrarchy and become the sole ruler of the Roman Empire. Maxentius drowned in the Tiber during the battle, and his body was later taken from the river and decapitated.
According to chroniclers, such as Eusebius of Caesarea and Lactantius, the battle marked the beginning of Constantine's conversion to Christianity. Eusebius of Caesarea recounts that Constantine looked up to the sun before the battle and saw a cross of light above it, and with it the Greek words Ἐν Τούτῳ Νίκα
("in this sign, conquer!"), often rendered in a Latin version, "in hoc signo vinces
." Constantine commanded his troops to adorn their shields with a Christian symbol (the Chi-Rho), and thereafter they were victorious. The Arch of Constantine, erected in celebration of the victory, certainly attributes Constantine's success to divine intervention; however, the monument does not display any overtly Christian symbolism, so there is no scholarly consensus on the events' relation to Constantine's conversion to Christianity.

Following the battle, Constantine ignored the altars to the gods prepared on the Capitoline, and did not carry out the customary sacrifices to celebrate a general's victorious entry into Rome, instead heading directly to the imperial palace. Most influential people in the empire, however, especially high military officials, had not been converted to Christianity, and still participated in the traditional religions of Rome; Constantine's rule exhibited at least a willingness to appease these factions. The Roman coins minted up to eight years after the battle still bore the images of Roman gods. The monuments he first commissioned, such as the Arch of Constantine, contained no reference to Christianity.
Constantine and Christianity
While the Roman Emperor Constantine the Great reigned (306-337 CE), Christianity began to transition to the dominant religion of the Roman Empire. Historians remain uncertain about Constantine's reasons for favoring Christianity, and theologians and historians have argued about which form of Early Christianity he subscribed to. There is no consensus among scholars as to whether he adopted his mother Helena's Christianity in his youth, or (as claimed by Eusebius of Caesarea) encouraged her to convert to the faith himself. Some scholars question the extent to which he should be considered a Christian emperor: "Constantine saw himself as an 'emperor of the Christian people.' If this made him a Christian is the subject of debate," although he allegedly received a baptism shortly before his death.
Constantine's decision to cease the persecution of Christians in the Roman Empire was a turning point for early Christianity, sometimes referred to as the Triumph of the Church, the Peace of the Church, or the Constantinian Shift. In 313, Constantine and Licinius issued the Edict of Milan, decriminalizing Christian worship. The emperor became a great patron of the Church and set a precedent for the position of the Christian emperor within the Church, and the notion of orthodoxy, Christendom, ecumenical councils, and the state church of the Roman Empire, declared by edict in 380. He is revered as a saint and isapostolos in the Eastern Orthodox Church and Oriental Orthodox Church for his example as a "Christian monarch."
The Shift East
Constantine built a new imperial residence in Byzantium and renamed the city Constantinople after himself; the city eventually became the capital of the empire for over one thousand years.
Explain why Constantine moved the capital of the empire to Constantinople, and the consequences that had for the empire as a whole
- After defeating Maxentius and his rebellion, Constantine gradually consolidated his military superiority over his rivals in the crumbling Tetrarchy, in particular Licinius.
- Eventually, Constantine defeated Licinius, making him the sole emperor of the empire, thereby ending the tetrarchy.
- Licinius' defeat came to represent the defeat of a rival center of Pagan and Greek-speaking political activity in the east, and it was proposed that a new eastern capital should represent the integration of the east into the Roman Empire as a whole; Constantine chose Byzantium.
- The city was thus founded in 324, dedicated on May 11, 330, and renamed Constantinople.
- The Byzantine Empire considered Constantine its founder, and the Holy Roman Empire reckoned him among the venerable figures of its tradition.
- Byzantium: An ancient Greek colony on the site that later became Constantinople, and eventually Istanbul.
- Byzantine Empire: Also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the east during Late Antiquity and the Middle Ages, when the empire's capital city was Constantinople.
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 this reason the later Eastern Empire would come to be known as the Byzantine Empire.
Background: War With Licinius
After defeating Maxentius, 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 Constantine's 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. 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.
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
Chi-Rho, and both sides saw the battle in religious terms. Outnumbered, but fired by their zeal, Constantine's 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 September 18, 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. Licinius's son (the son of Constantine's half-sister) was also killed. Thus, Constantine became the sole emperor of the Roman Empire.
Foundation 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 May 11, 330, and renamed Constantinopolis
("Constantine's 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." Constantinople was a superb base from which to guard the Danube River, and it was reasonably close to the eastern frontiers. Constantine also began the building of the great fortified walls, which were expanded and rebuilt in subsequent ages.

Historian J.B. Bury asserts that "the foundation of Constantinople [...] inaugurated a permanent division between the Eastern and Western, the Greek and the Latin, halves of the empire—a division to which events had already pointed—and affected decisively the whole subsequent history of Europe."
The Byzantine Empire considered Constantine its founder, and the Holy Roman Empire reckoned him among the venerable figures of its tradition. In the later Byzantine state, it had become a great honor for an emperor to be hailed as a "new Constantine." Ten emperors, including the last emperor of the Eastern Roman Empire, carried the name. Monumental Constantinian forms were used at the court of Charlemagne to suggest that he was Constantine's successor and equal. Constantine acquired a mythic role as a warrior against "heathens."
The Decline and Fall of the Roman Empire
The Fall of the Western Roman Empire was the period of decline during which the empire disintegrated and split into numerous successor states.
Analyze, broadly, the causes of the fall of the Roman Empire
- Throughout the 5th century, the empire's territories in western Europe and northwestern Africa, including Italy, fell to various invading or indigenous peoples, in what is sometimes called the Migration Period.
- By the late 3rd century, the city of Rome no longer served as an effective capital for the emperor, and various cities were used as new administrative capitals. Successive emperors, starting with Constantine, privileged the eastern city of Byzantium, which he had entirely rebuilt after a siege.
- In 476, after being refused lands in Italy, Odacer and his Germanic mercenaries took Ravenna, the Western Roman capital at the time, and deposed Western Emperor Romulus Augustus. The whole of Italy was quickly conquered, and Odoacer 's rule became recognized in the Eastern Empire.
- Four broad schools of thought exist on the decline and fall of the Roman Empire: decay owing to general malaise, monocausal decay, catastrophic collapse, and transformation.
- Odoacer: A soldier, who came to power in the Western Roman Empire in 476 CE. His reign is commonly seen as marking the end of the Western Roman Empire.
- Migration Period: Also known as the period of the Barbarian Invasions, it was a period of intensified human migration in Europe from about 400 to 800 CE, during the transition from Late Antiquity to the Early Middle Ages.
The Fall of the Western Roman Empire was the process of decline during which the empire failed to enforce its rule, and its vast territory was divided into several successor polities. The Roman Empire lost the strengths that had allowed it to exercise effective control; modern historians mention factors including the effectiveness and numbers of the army, the health and numbers of the Roman population, the strength of the economy, the competence of the emperor, the religious changes of the period, and the efficiency of the civil administration. Increasing pressure from barbarians outside Roman culture also contributed greatly to the collapse. The reasons for the collapse are major subjects of the historiography of the ancient world, and they inform much modern discourse on state failure.
By 476 CE, when Odoacer deposed Emperor Romulus, the Western Roman Empire wielded negligible military, political, or financial power and had no effective control over the scattered western domains that could still be described as Roman. Invading "barbarians" had established their own polities on most of the area of the Western Empire. While its legitimacy lasted for centuries longer and its cultural influence remains today, the Western Empire never had the strength to rise again.
It is important to note, however, that the so-called fall of the Roman Empire specifically refers to the fall of the Western
Roman Empire, since the Eastern Roman Empire, or what became known as the Byzantine Empire, whose capital was founded by Constantine, remained for another 1,000 years. Theodosius was the last emperor who ruled over the whole empire. After his death in 395, he gave the two halves of the empire to his two sons, Arcadius and Honorius; Arcadius became ruler in the east, with his capital in Constantinople, and Honorius became ruler in the west, with his capital in Milan, and later Ravenna.
Rome in the 5th Century CE
Throughout the 5th century, the empire's territories in western Europe and northwestern Africa, including Italy, fell to various invading or indigenous peoples in what is sometimes called the Migration Period, also known as the Barbarian Invasions, from the Roman and South European perspective. The first migrations of peoples were made by Germanic tribes, such as the Goths, Vandals, Angles, Saxons, Lombards, Suebi, Frisii, Jutes and Franks; they were later pushed westwards by the Huns, Avars, Slavs, and Bulgars.
Although the eastern half still survived with borders essentially intact for several centuries (until the Muslim conquests), the Empire as a whole had initiated major cultural and political transformations since the Crisis of the Third Century, with the shift towards a more openly autocratic and ritualized form of government, the adoption of Christianity as the state religion, and a general rejection of the traditions and values of Classical Antiquity.
The reasons for the decline of the Empire are still debated today, and are likely multiple. Historians infer that the population appears to have diminished in many provinces (especially western Europe), judging from the diminishing size of fortifications built to protect the cities from barbarian incursions from the 3rd century on. Some historians even have suggested that parts of the periphery were no longer inhabited, because these fortifications were restricted to the center of the city only. By the late 3rd century, the city of Rome no longer served as an effective capital for the emperor, and various cities were used as new administrative capitals. Successive emperors, starting with Constantine, privileged the eastern city of Byzantium, which he had entirely rebuilt after a siege. Later renamed Constantinople, and protected by formidable walls in the late 4th and early 5th centuries, it was to become the largest and most powerful city of Christian Europe in the Early Middle Ages. Since the Crisis of the Third Century, the empire was intermittently ruled by more than one emperor at once (usually two), presiding over different regions.
The Latin-speaking west, under dreadful demographic crisis, and the wealthier Greek-speaking east, also began to diverge politically and culturally. Although this was a gradual process, still incomplete when Italy came under the rule of barbarian chieftains in the last quarter of the 5th century, it deepened further afterward, and had lasting consequences for the medieval history of Europe.
In 476, after being refused lands in Italy, Orestes' Germanic mercenaries, under the leadership of the chieftain Odoacer, captured and executed Orestes and took Ravenna, the Western Roman capital at the time, deposing Western Emperor Romulus Augustus. The whole of Italy was quickly conquered, and Odoacer's rule became recognized in the Eastern Empire. Meanwhile, much of the rest of the Western provinces were conquered by waves of Germanic invasions, most of them being disconnected politically from the east altogether, and continuing a slow decline. Although Roman political authority in the west was lost, Roman culture would last in most parts of the former western provinces into the 6th century and beyond.

Theories on the Decline and Fall
The various theories and explanations for the fall of the Roman Empire in the west may be very broadly classified into four schools of thought (although the classification is not without overlap):
- Decay owing to general malaise
- Monocausal decay
- Catastrophic collapse
The tradition positing general malaise goes back to the historian, Edward Gibbon, who argued that the edifice of the Roman Empire had been built on unsound foundations from the beginning. According to Gibbon, the fall was—in the final analysis—inevitable. On the other hand, Gibbon had assigned a major portion of the responsibility for the decay to the influence of Christianity, and is often, though perhaps unjustly, seen as the founding father of the school of monocausal explanation. On the other hand, the school of catastrophic collapse holds that the fall of the empire had not been a pre-determined event and need not be taken for granted. Rather, it was due to the combined effect of a number of adverse processes, many of them set in motion by the Migration Period, that together applied too much stress to the empire's basically sound structure. Finally, the transformation school challenges the whole notion of the 'fall' of the empire, asking instead to distinguish between the fall into disuse of a particular political dispensation, anyway unworkable towards its end; and the fate of the Roman civilization that under-girded the empire. According to this school, drawing its basic premise from the Pirenne thesis, the Roman world underwent a gradual (though often violent) series of transformations, morphing into the medieval world. The historians belonging to this school often prefer to speak of Late Antiquity, instead of the Fall of the Roman Empire.
