The Roman Empire is the term conventionally used to describe the Roman state in the centuries following its reorganization under the leadership of Caesar Augustus. Although Rome possessed a collection of tribute-states for centuries before the autocracy of Augustus, the pre-Augustan state is conventionally described as the Roman Republic. The difference between the Roman Empire and the Roman Republic lies primarily in the governing bodies and their relationship to each other. For many years historians made a distinction between the Principate, the period from Augustus until the Crisis of the Third Century, and the Dominate, the period from Diocletian until the end of the Empire in the West. According to this theory, during the Principate (from the Latin word princeps, meaning "the first", the only title Augustus would permit himself) the realities of dictatorship were concealed behind Republican forms; while during the Dominate (from the word dominus, meaning "Master") imperial power showed its naked face, with golden crowns and ornate imperial ritual. We now know that the situation was far more nuanced: certain historical forms continued until the Byzantine period, more than one thousand years after they were created, and displays of imperial majesty were common from the earliest days of the Empire.
The provinces of the Roman Empire.
Over the course of its history the Roman Empire controlled all of the Hellenized states that bordered the Mediterranean Sea, as well as the Celtic regions of Western Europe. The administration of the Roman Empire eventually evolved into separate Eastern and Western halves, more or less following this cultural division. They are respectively known as the Eastern Roman Empire and the Western Roman Empire. By the time that Odoacer took power of the West in 476 the Western half was clearly evolving in new directions, with the Church absorbing much of the administrative and charitable roles previously filled by the secular government. The Eastern half of the Empire, centered around Constantinople, the city of Constantine the Great, remained the heartland of the Roman state until 1453 when the Byzantine Empire fell to the Ottoman Turks.
The Roman Empire's influence on government, law, and monumental architecture, as well as many other aspects of Western life remains inescapable. Roman titles of power were adopted by successor states and other entities with imperial pretensions, including the Frankish kingdom, the Holy Roman Empire, the first and second Bulgarian empires(see List of Bulgarian monarchs), the Russian/Kiev dynasties (see czars), and the German Empire (see Kaiser).

As a matter of convenience, the Roman Empire is held to have begun with the constitutional settlement following the Battle of Actium in 31 BC. In fact the Republican institutions at Rome had been destroyed over the preceding century and Rome had been effectively under one-man rule since the time of Sulla.
The reign of Augustus marks an important turning point, though. By the time of Actium, there was no one left alive who could recall functional Republican institutions or a time when there was no civil war in Rome. Forty-five years later, at Augustus's death, there would have been few living who could recall a time before Augustus himself. The average Roman had a life expectancy of only forty years. The long, peaceful and consensual reign of Augustus allowed a generation to live and die knowing no other form of rule, or indeed no other ruler. This was critically important to creating a mindset that would allow hereditary monarchy to exist in a Rome that had killed Julius Caesar for his regal pretensions. Whether or not the people of Rome welcomed one-man rule, in the Age of Augustus, it was all they knew, and so it would remain for many centuries. During his reign trade links developed with regions as far as India and China.
Augustus's reign was notable for several long-lasting achievements that would define the Empire:
- Creating a hereditary office, which we refer to as Emperor of Rome.
- Fixing the payscale. Duration of Roman military service marked the final step in the evolution of the Roman Army from a citizen army to a professional one.
- Creating the Praetorian Guard, which would make and unmake emperors for centuries.
- Expansion to the natural borders of the Empire. The borders reached upon Augustus's death remained the limits of Empire, with minimal exceptions, for the next four hundred years.
- Creating a civil service outside of the Senatorial structure, leading to a continuous weakening of Senatorial authority.
- The lex Julia of 18 BC and the lex Papia Poppaea of AD 9, which rewarded childbearing and penalized celibacy.
- Promulgation of the cult of the Deified Julius Caesar throughout the Empire, and the encouragement of a quasi-godlike status for himself in his own lifetime in the Hellenist East. This tradition lasted until the time of Constantine, who was made both a Roman god and "the Thirteenth Apostle" upon his death.
Main article: Roman culture
The Augustan period saw a tremendous outpouring of cultural achievement in the areas of poetry, history, sculpture and architecture.
The Age of Augustus is paradoxically far more poorly documented than the Late Republican period that preceded it. While Livy wrote his magisterial history during Augustus's reign and his work covered all of Roman history through 9 BC, only epitomes survive of his coverage of the Late Republican and Augustan periods. Our important primary sources for this period include the:
Though primary accounts of this period are few, works of poetry, legislation and engineering from this period provide important insights into Roman life. Archeology, including maritime archeology, aerial surveys, epigraphic inscriptions on buildings, and Augustan coinage, has also provided valuable evidence about economic, social and military conditions.
Secondary sources on the Augustan Age include Tacitus, Dio Cassius, Plutarch and Suetonius. Josephus's Jewish Antiquities is the important source for Judea in this period, which became a province during Augustus's reign.
Julio-Claudian dynasty: Augustus' heirs
Augustus's strategy of intermarriage between the Julii and Claudii resulted in a combination of family and political relationships known as the Julio-Claudian dynasty.
The early years of Tiberius' reign were peaceful and relatively benign. Tiberius secured the power of Rome and enriched the treasury. However, Tiberius's reign soon became characterized by paranoia and slander. In 19, he was blamed for the death of his nephew, the popular Germanicus. In 23 his own son Drusus died. More and more, Tiberius retreated into himself. He began a series of treason trials and executions. He left power in the hands of the commander of the guard, Aelius Sejanus. Tiberius himself retired to live at his villa on the island of Capri in 26, leaving Sejanus in charge. Sejanus carried on the persecutions with relish. He also began to consolidate his own power; in 31 he was named co-consul with Tiberius and married Livilla, the emperor's niece. At this point he was hoisted by his own petard: the Emperor's paranoia, which he had so ably exploited for his own gain, was turned against him. Sejanus was put to death, along with many of his cronies, the same year. The persecutions continued apace until Tiberius's death in 37.
At the time of Tiberius's death most of the people who might have succeeded him had been brutally murdered. The logical successor (and Tiberius's own choice) was his grandnephew, Germanicus's son Gaius (better known as Caligula). Caligula started out well, by putting an end to the persecutions and burning his uncle's records. Unfortunately, he quickly lapsed into illness. The Caligula that emerged in late 37 may have suffered from epilepsy, and was more probably insane. He ordered his soldiers to invade Britain, but changed his mind at the last minute and had them pick sea shells on the northern end of France instead. It is believed he carried on incestuous relations with his sisters. He had ordered a statue of himself to be erected in the Temple at Jerusalem, which would have undoubtedly led to revolt had he not been dissuaded. In 41, Caligula was assassinated by the commander of the guard Cassius Chaerea. The only member left of the imperial family to take charge was another nephew of Tiberius's, Tiberius Claudius Drusus Nero Germanicus, better known as the emperor Claudius.
Claudius had long been considered a weakling and a fool by the rest of his family. He was, however, neither paranoid like his uncle Tiberius, nor insane like his nephew Caligula, and was therefore able to administer the empire with reasonable ability. He improved the bureaucracy and streamlined the citizenship and senatorial rolls. He also proceeded with the conquest and colonization of Britain (in 43), and incorporated more Eastern provinces into the empire. In Italy, he constructed a winter port at Ostia, thereby providing a place for grain from other parts of the Empire to be brought in inclement weather.
On the home front, Claudius was less successful. His wife Messalina cuckolded him; when he found out, he had her executed and married his niece, Agrippina the younger. She, along with several of his freedmen, held an inordinate amount of power over him, and very probably killed him in 54. Claudius was deified later that year. The death of Claudius paved the way for Agrippina's own son, the 16-year-old Lucius Domitius, or, as he was known by this time, Nero.
Initially, Nero left the rule of Rome to his mother and his tutors, particularly Lucius Annaeus Seneca. However, as he grew older, his desire for power increased; he had his mother and tutors executed. During Nero's reign, there were a series of riots and rebellions throughout the Empire: in Britain, Armenia, Parthia, and Judaea. Nero's inability to manage the rebellions and his basic incompetence became evident quickly and in 68, even the Imperial guard renounced him. Nero committed suicide, and the year 69 (known as the Year of the Four Emperors) was a year of civil war, with the emperors Galba, Otho, Vitellius, and Vespasian ruling in quick succession. By the end of the year, Vespasian was able to solidify his power as emperor of Rome.
Vespasian was a remarkably successful Roman general who had been given rule over much of the eastern part of the Roman Empire. He had supported the imperial claims of Galba; however, on his death, Vespasian became a major contender for the throne. After the suicide of Otho, Vespasian was able to hijack Rome's winter grain supply, placing him in a good position to defeat his remaining rival, Vitellius. On December 20, 69, some of Vespasian's partisans were able to occupy Rome. Vitellius was murdered by his own troops, and the next day, Vespasian was confirmed as Emperor by the Senate.
Vespasian was quite the autocrat, and gave much less credence to the Senate than his Julio-Claudian predecessors. This was typified by his dating his accession to power from July 1, when his troops proclaimed him emperor, instead of December 21, when the Senate confirmed his appointment. He would, in later years, expel dissident senators.
Vespasian was able to liberate Rome from the financial burdens placed upon it by Nero's excesses and the civil wars. By increasing tax rates dramatically (sometimes as much as doubling them) he was able to build up a surplus in the treasury and embark on public works projects. It was he who first commissioned the Roman Colosseum; he also built a forum whose centerpiece was a temple to Peace.
Vespasian was also an effective emperor for the provinces. His generals quelled rebellions in Syria and Germany. In fact, in Germany he was able to expand the frontiers of the empire, and a great deal more of Britain was brought under Roman rule. He also extended Roman citizenship to the inhabitants of Spain.
Another example of his monarchical tendencies was his insistence that his sons Titus and Domitian would succeed him; the imperial power was not seen as hereditary at this point. Titus, who had some military successes early in Vespasian's reign, was seen as the heir presumptive to the throne; Domitian was seen as somewhat less disciplined and responsible. Titus joined his father in the offices of censor and consul and helped him reorganize the senatorial rolls. Upon Vespasian's death in 79, Titus was immediately confirmed as Emperor.
Titus' short reign was marked by disaster: in 79, Vesuvius erupted in Pompeii, and in 80, a fire decimated much of Rome. His generosity in rebuilding after these tragedies made him very popular. Titus was very proud of his work on the vast amphitheater begun by his father. He held the opening ceremonies in the still unfinished edifice during the year 80, celebrating with a lavish show that featured 100 gladiators and lasted 100 days. However, it was during Domitian's reign that the Colosseum was completed. Titus died in 81, at the age of 41; it was rumored that his brother Domitian murdered him in order to become his successor.
Domitian did not live up to the good name left for the family by his father and elder brother. While his offenses may have been exaggerated by hostile later generations, it is clear that he did not like to share power. It had become accepted by Domitian's time that the emperor would simultaneously hold many of the magistracies established during Republican times (for instance the censorship and the tribunate), but it was still customary for other politicians to have those powers as well. Domitian wanted to claim authority for himself alone, causing him to alienate the Senate as well as the people.
Roman empire at its maximal extent (AD 117)
The next century came to be known as the period of the "Five Good Emperors", in which the successions were peaceful though not dynastic, and the Empire was prosperous. The emperors were Nerva, Trajan, Hadrian, Antoninus Pius, and Marcus Aurelius.
Under Trajan, the Empire's borders briefly achieved their maximum extension with provinces created in Mesopotamia.
The period of the "five good emperors" was brought to an end by the reign of Commodus from 180 to 192. Commodus was the son of Marcus Aurelius. He was co-emperor with his father from 177. When he became sole emperor upon the death of his father in 180, it was at first seen as a hopeful sign by the people of the Roman Empire. Nevertheless, as generous and magnanimous as his father was, Commodus turned out to be just the opposite.
Commodus is often thought to have been insane, and he was certainly given to excess. He began his reign by making an unfavorable peace treaty with the Marcomanni, who had been at war with Marcus Aurelius. Commodus also had a passion for gladiatoral combat, which he took so far as to take to the arena himself, dressed as a gladiator. In 190, a part of the city of Rome burned, and Commodus took the opportunity to "re-found" the city of Rome in his own honor, as Colonia Commodiana. The months of the calendar were all renamed in his honor, and the senate was renamed as the Commodian Fortunate Senate. The army became known as the Commodian Army. Commodus was strangled in his sleep in 192, a day before he planned to march into the Senate dressed as a gladiator to take office as a consul. Upon his death, the Senate passed damnatio memoriae on him and restored the proper name to the city of Rome and its institutions. The popular movies The Fall of the Roman Empire (1964) and Gladiator (2000) were loosely based on the career of the emperor Commodus, although they should not be taken as an accurate historical depictions of his life.
The Severan dynasty includes the increasingly troubled reigns of Septimius Severus (193-211), Caracalla (211-217), Macrinus (217-218), Elagabalus (218-222), and Alexander Severus (222-235). The founder of the dynasty, Lucius Septimius Severus, belonged to a leading native family of Leptis Magna in Africa who allied himself with a prominent Syrian family by his marriage to Julia Domna. Their provincial background and cosmopolitan alliance, eventually giving rise to imperial rulers of Syrian background, Elagabalus and Alexander Severus, testifies to the broad political franchise and economic development of the Roman empire that had been achieved under the Antonines. A generally successful ruler, Septimius Severus cultivated the army's support with substantial remuneration in return for total loyalty to the emperor and substituted equestrian officers for senators in key administrative positions. In this way, he successfully broadened the power base of the imperial administration throughout the empire. Abolishing the regular standing jury courts of Republican times, Septimius Severus was likewise able to transfer additional power to the executive branch of the government, of which he was decidedly the chief representative.
Septimius Severus' son, Marcus Aurelius Antoninus - nicknamed Caracalla - removed all legal and political distinction between Italians and provincials, enacting the Constitutio Antoniniana in 212 which extended full Roman citizenship to all free inhabitants of the empire. Caracalla was also responsible for erecting the famous Baths of Caracalla in Rome, their design serving as an architectural model for many subsequent monumental public buildings. Increasingly unstable and autocractic, Caracalla was assassinated by the praetorian prefect Macrinus in 217, who succeeded him briefly as the first emperor not of senatorial rank. The imperial court, however, was dominated by formidable women who arranged the succession of Elagabalus in 218, and Alexander Severus, the last of the dynasty, in 222. In the last phase of the Severan principate, the power of the Senate was somewhat revived and a number of fiscal reforms were enacted. Despite early successes against the Sassanian Empire in the East, Alexander Severus' increasing inability to control the army led eventually to its mutiny and his assassination in 235. The death of Alexander Severus ushered in a subsequent period of soldier-emperors and almost a half-century of civil war and strife.
Crisis of the 3rd Century (235AD-275AD)
The Crisis of the 3rd Century is a commonly applied name for the crumbling and near collapse of the Roman Empire between 235 and 275. During this period, Rome was ruled by more than 35 individuals, most of them prominent generals who assumed Imperial power over all or part of the empire, only to lose it by defeat in battle, murder, or death. After 35 years of this, the Empire was on the verge of death, and only the military skill of Aurelian, one of Rome's greatest emperors, restored the empire to its natural boundaries.
The transition from a single united empire to the later divided Western and Eastern empires was a gradual transformation. In July, 285, Diocletian defeated rival Emperor Carinus and briefly became sole emperor of the Roman Empire.
Diocletian felt that the system of Roman imperial government was unsustainable in the face of internal pressures and military threats on two fronts. He gave Maximian the title of Caesar, which was the traditional manner by which an emperor (Augustus) designated his successor. However Diocletian made Maximian an Augustus as well. Imperial power was therefore divided between two people. Diocletian's sphere of influence was the East, Maximian's the West.
In 293 authority was further divided when each Augustus took a Caesar to aid him in administrative matters; Diocletian was assisted by Galerius and Maximian by Constantius Chlorus. This constituted what was called in Latin a quadrumvirate and in Greek a Tetrarchy; the leadership of four. The system allowed the peaceful succession of the Augusti. On May 1, 305 Diocletian and Maximian abdicated in favor of their Caesars ; apparently choosing retirement to death in office. Galerius named the two new Caesars: his nephew Maximinus for himself and Flavius Valerius Severus for Constantius.
The Tetrarchy would effectively collapse with the death of Constantius Chlorus on July 25, 306. Constantius' troops in Eboracum immediately ploclaimed his son Constantine the Great an Augustus. In August, 306, Galerius promoted Severus to the position of Augustus. A revolt in Rome supported another claimant to the same title: Maxentius, son of Maximian, who was proclaimed Augustus on October 28, 306. His election was supported by the Praetorian Guard. This left the Empire with four Augusti (Galerius, Constantine, Severus and Maxentius) and a sole Caesar (Maximinus).
The year 307 saw the return of Maximian to the role of Augustus alongside his son. Galerius and Severus campaigned against them in Italy. Severus was killed under command of Maxentius on September 16, 307. The two Augusti of Italy also managed to ally themselves with Constantine by having Constantine marry Fausta, the daughter of Maximian and sister of Maxentius. The end of 307 saw the Empire with four Augusti (Maximian, Galerius, Constantine and Maxentius) and a sole Caesar (Maximinus).
The five were briefly joined by another Augustus in 308, Domitius Alexander, vicarius of the Roman province of Africa under Maxentius, proclaimed himself Augustus. Before long he was captured by Rufus Volusianus and Zenas. Alexander ended his life in captivity in 309. The current situation of conflict between the various rivalrous Augusti was resolved in the Congress of Carnuntum with the participation of all four Augusti and the Caesar. The final decisions were taken on November 11, 308:
- Galerius remained Augustus of the Eastern Roman Empire.
- Maximinus remained Caesar of the Eastern Roman Empire.
- Maximian was forced to abdicate.
- Maxentius received official recognition as Augustus of the Western Roman Empire.
- Constantine received official recognition but was demoted to Caesar of the Western Roman Empire.
- Licinius replaced Maximian as Augustus of the Western Roman Empire.
Problems however continued. Maximinus demanded to be promoted to Augustus. He proclaimed himself to be one on May 1, 310. Maximian similarly proclaimed himself an Augustus for a third and final time. He was killed by his son-in-law Constantine in July, 310. The end of the year again found the Empire with four Augusti (Galerius, Maximinus, Maxentius and Licinius) and a sole Caesar (Constantine).
Galerius died in May 311 leaving Maximinus sole ruler of the Eastern Roman Empire. Meanwhile Maxentius declared a war on Constantine under the pretext of avenging his executed father. He was among the casualties of the Battle of Milvian Bridge on October 28, 312. Constantine was promoted to Augustus.
This left the Empire in the hands of the three remaining Augusti, Maximinus, Constantine and Licinius. Licinius allied himself with Constantine, cementing the alliance by marriage to his younger half-sister Constantia in March 313 and joining open conflict with Maximinus. In August 313 Maximinus met his death at Tarsus in Cilicia. The two remaining Augusti divided the Empire again in the pattern established by Diocletian, Constantine becoming Augustus of the Western Roman Empire and Licinius Augustus of the Eastern Roman Empire.
This division continued until 324. A final war between the last two remaining Augusti ended with the deposition of Licinius and the elevation of Constantine to sole Emperor of the Roman Empire. Deciding that the empire needed a new capital, Constantine chose the site of Byzantium for the new city. He refounded it as Nova Roma, but it was popularly called Constantinople: Constantine's City.
Christian Empire (324AD-395AD)
The beginning of the Roman Empire as a Christian empire lies in 313 AD, with the Edict of Milan. The edict was signed under the reign of Constantine I. The edict made Christianity one of the official religions of Rome.
Christianity became the single official religion of Rome under Theodosius (r. 379-395 AD). Initially the emperor had control over the church. During Theodosius' reign he randomly slaughtered a village. Upon his return to Rome the Bishop Ambrose refused to let Theodosius enter the church until he made a public repentance. Theodosius did and from then on the church's powers grew. Eventually the church would gain enough power that it would outlast the empire in the west.
Late Antiquity in the West (395AD-476AD)
In popular history, the year 476 is generally accepted as the end of the Western Roman Empire. In that year, Odoacer disposed of his puppet Romulus Augustus (475-476), and for the first time did not bother to induct a successor, choosing instead to rule as a representative of the Eastern Emperor (although Julius Nepos, the emperor deposed by Romulus Augustulus, continued to rule Illyricum until his death in 480, at which point Odoacer annexed the remainder of the Western Empire to his Italian kingdom). The last Emperor who ruled from Rome, however, had been Theodosius, who removed the seat of power to Mediolanum (Milan). Edward Gibbon, in writing The History of the Decline and Fall of the Roman Empire knew not to end his narrative at 476. The great corpse continued to twitch, into the 6th century.
On the other hand, in 409, with the Emperor of the West fled from Milan to Ravenna and all the provinces wavering in loyalties, the Goth Alaric I, in charge at Rome, came to terms with the senate, and with their consent set up a rival emperor and invested the prefect of the city, a Greek named Priscus Attalus, with the diadem and the purple robe. In the following year when the Goths rampaged in the City, local power was in the hands of the Bishop of Rome. The transfer of power to Christian pope and military dux had been effected: the Western Empire was effectively dead, though no contemporary knew it.
The next seven decades played out as aftermath. Theodoric the Great as King of the Goths, couched his legitimacy in diplomatic terms as being the representative of the Emperor of the East. Consuls were appointed regularly through his reign: a formula for the consular appointment is provided in Cassiodorus' Book VI. The post of consul was last filled in the west under Theodoric's successor, Athalaric, until he died in 534. Ironically the Gothic War in Italy, which was meant as the reconquest of a lost province for the Emperor of the East and a re-establishment of the continuity of power, actually caused more damage and cut more ties of continuity with the Antique world than the attempts of Theodoric and his minister Cassiodorus to meld Roman and Gothic culture within a Roman form.
In essence, the "fall" of the Roman Empire to a contemporary depended a great deal on where they were and their status in the world. On the great villas of the Italian Campagna, the seasons rolled on without a hitch. The local overseer may have been representing an Ostrogoth, then a Lombard duke, then a Christian bishop, but the rhythm of life and the horizons of the imagined world remained the same. Even in the decayed cities of Italy consuls were still elected. In Auvergne, at Clermont, the Gallo-Roman poet and diplomat Sidonius Apollinaris, bishop of Clermont, realized that the local "fall of Rome" came in 475, with the fall of the city to the Visigoth Euric. In the north of Gaul the Franks could not be taken for Roman, but in Hispania the last Arian Visigothic king Leovigild considered himself the heir of Rome. In Alexandria, dreams of a "Christian Empire" with genuine continuity were shattered when a rampaging mob of Christians were encouraged to sack and destroy the Serapeum in 392. Hispania Baetica was still essentially Roman when the Moors came in 711, but in the northwest, the invasion of the Suevi broke the last frail links with Roman culture in 409. In Aquitania and Provence, cities like Arles were not abandoned, but Roman culture in Britain collapsed in waves of violence after the last legions evacuated: the final legionary probably left Britain in 409. In Athens the end came for some in 529, when the Emperor Justinian closed the Neoplatonic Academy and its remaining members fled east for protection under the rule of Sassanid king Khosrau I; for other Greeks it had come long before, in 396, when Christian monks led Alaric I to vandalize the site of the Eleusinian Mysteries.
Finally to footnote, the Romans didn't share all their knowledge. An example is cement. (See Bridge: History.) After the "fall" of Rome the technology for cement was "lost."
From Roman to Byzantine in the East
Under Constantine (330AD-337AD) and his sons (337AD-361AD)
Constantinople would serve as the capital of Constantine the Great from May 11, 330 to his death on May 22, 337. The Empire was parted again among his three surviving sons.The Western Roman Empire was divided among the eldest son Constantine II and the youngest son Constans. The Eastern Roman Empire along with Constantinople were the share of middle son Constantius II.
Constantine II was killed in conflict with his youngest brother in 340. Constans was himself killed in conflict with army proclaimed Augustus Magnentius on January 18, 350. Magnentius was at first opposed in the city of Rome by self-proclaimed Augustus Nepotianus, a paternal first cousin of Constans. Nepotianus was killed alongside his mother Eutropia. His other first cousin Constantia convinced Vetriano to proclaim himself Caesar in opposition to Magnentius. Vetriano served a brief term from March 1 to December 25, 350. He was then forced to abdicate by the legitimate Augustus Constantius. The usurper Magnentius would continue to rule the Western Roman Empire till 353 while in conflict with Constantius. His eventual defeat and suicide left Constantius as sole Emperor.
Constantius rule would however be opposed again in 360. He had named his paternal half-cousin and brother-in-law Julian as his Caesar of the Western Roman Empire in 355. During the following five years, Julian had a series of victories against invading Germanic tribes, including the Alamanni. This allowed him to secure the Rhine frontier. His victorious Gallic troops thus ceased campaigning. Constantius send orders for the troops to be transferred to the east as reinforcements for his own currently unsuccessful campaign against Shapur II of Persia. This order led the Gallic troops to an insurrection. They proclaimed their commanding officer Julian to be an Augustus. Both Augusti were not ready to lead their troops to another Roman Civil War. Constantius' timely demise on November 3, 361 prevented this war from ever occuring.
Under Julian (361AD-363AD) & Jovian (363AD-364AD)
Julian would serve as the sole Emperor for two years. He had received his baptism as a Christian years before. But apparently no longer considered himself one. His reign would see the ending of restriction and persecution of paganism introduced by his uncle and father-in-law Constantine the Great and his cousins and brother-in-laws Constantine II, Constans and Constantius II. He instead placed similar restrictions and unofficial persecution of Christianism. His edict of tolerance in 362 ordered the reopening of pagan temples, the reinstitution of alienated temple properties. And more problematic for the Christian Church, the recalling of previously exiled Christian bishops. Returning Orthodox and Arian bishops resumed their conflicts thus further weakening the Church as a whole.
Julian himself was not a traditional pagan. His personal beliefs were largely influenced by Neoplatonism and Theurgy. He produced works of philosophy arguing his beliefs. His brief renaissance of paganism would however end with his death. Julian eventually resumed the war against Shapur II of Persia. He received a mortal wound in battle and died on June 26, 363. An ironic fate for someone who reportedly believed himself a reincarnation of Alexander the Great. He was considered a hero by pagan sources of his time and a villain by Christian ones. Later historians have treated him as a controversial figure.
Julian died childless and with no designated successor. The officers of his army elected the rather obscure officer Jovian as an Augustus. He is remembered for signing an unfavorable peace treaty with Persia and restoring the privileges of Christianity. He is considered a Christian himself though little is known of his beliefs. Jovian himself died on February 17, 364.
Valentinian Dynasty (364AD-392AD)
The role of choosing a new Augustus fell again to army officers. On February 28, 364, Pannonian officer Valentinian I was elected Augustus in Nicaea, Bithynia. The army however had twice been left leaderless in less than a year. The officers demanded for Valentinian to choose a co-ruler. On March 28, 364, Valentinian chose his own younger brother Valens. The two new Augusti would part the Empire in the pattern established by Diocletian. Valentinian would administer the Western Roman Empire while Valens received the Eastern Roman Empire.
Valens' election would soon be disputed.
