Flavius Claudius Iulianus, known also as Julianus, Julian, Julian the Apostate or Julian the Philosopher (331/332[1] – 26 June 363, Greek: Ιουλιανός), was Roman Emperor (Caesar, November 355 to February 360; Augustus, February 360 to June 363), last of the Constantinian dynasty. Julian was a man of "unusually complex character": he was "the military commander, the theosophist, the social reformer, and the man of letters".[2]
Julian was the last non-Christian ruler of the Roman Empire and it was his desire to bring the empire back to its ancient Roman values in order to save it from "dissolution".[3] He purged the top-heavy state bureaucracy and attempted to revive traditional Roman religious practices at the cost of Christianity. His rejection of Christianity in favour of Neoplatonic paganism caused him to be called Julian the Apostate by the church, as Edward Gibbon wrote:
The triumph of the party which he deserted and opposed has fixed a stain of infamy on the name of Julian; and the unsuccessful apostate has been overwhelmed with a torrent of pious invectives, of which the signal was given by the sonorous trumpet of Gregory Nazianzen.

In 363, after a reign of only 19 months as absolute ruler of the Roman Empire, Julian was killed in Persia during a campaign against the Sassanid Empire.
Flavius Claudius Julianus, born in May or June 332[5] or 331 in Constantinople, was the son of Julius Constantius (consul in 335), half brother of Emperor Constantine I, and his second wife, Basilina, both Christians. His paternal grandparents were Western Roman Emperor Constantius Chlorus and his second wife, Flavia Maximiana Theodora. His maternal grandfather was Julius Julianus, praetorian prefect of the East under emperor Licinius from 315 to 324 and consul after 325.[6] The name of Julian's maternal grandmother is unknown.
In the turmoil after the death of Constantine in 337, in order to establish himself as sole emperor, Julian's zealous Arian Christian cousin Constantius II led a massacre of Julian's family. Constantius II ordered the murders of many descendants from the second marriage of Constantius Chlorus and Theodora, leaving only Constantius and his brothers Constantine II and Constans I, and their cousins, Julian and Gallus (Julian's half-brother), as the surviving males related to Emperor Constantine. Constantius II, Constans I, and Constantine II were proclaimed joint emperors, each ruling a portion of Roman territory. Julian and Gallus were excluded from public life and given a strictly Arian Christian education.
Initially growing up in Bithynia, raised by his maternal grandmother, at the age of seven he was under the guardianship of Eusebius of Nicomedia, the semi-Arian Christian Bishop of Nicomedia, and taught by Mardonius, a Gothic eunuch, whom Julian wrote warmly of later. After Eusebius died in 342, both Julian and Gallus were exiled to the imperial estate of Macellum in Cappadocia. Here Julian met the Christian bishop George of Cappadocia, who lent him books from the classical tradition. At the age of 18, the exile was lifted and he dwelt briefly in Constantinople and Nicomedia.[7]
He became a lector, a minor office in the Christian church, and his later writings show a detailed knowledge of the Bible, likely acquired in his early life.[8] (Looking back on his life in 362, Julian wrote, in his thirty-first year, that he had spent twenty years in the way of Christianity and twelve in the true way (i.e. the way of Helios).[9])
Julian studied Neoplatonism in Asia Minor in 351, at first under Aedesius, the philosopher, and then Neoplatonic theurgy from Aedesius' student, Maximus of Ephesus. He was summoned to Constantius' court in Milan in 354 and kept there for a year; in the summer and fall of 355, he was permitted to study in Athens. While there, Julian became acquainted with two men who later became both bishops and saints: Gregory of Nazianzus and Basil the Great; in the same period, Julian was also initiated into the Eleusinian Mysteries, which he would later try to restore.
Constantine II died in 340 when he attacked his brother Constans. Constans in turn fell in 350 in the war against the usurper Magnentius. This left Constantius II as the sole remaining emperor. In need of support, in 351 he made Julian's half-brother, Gallus, Caesar of the East, while Constantius II himself turned his attention westward to Magnentius, whom he defeated decisively that year. In 354 Gallus, who had imposed a rule of terror over the territories under his command, was executed. Julian was summoned to court, and held for a year, under suspicion of treasonable intrigue, first with his brother and then with Claudius Silvanus; he was cleared, in part because the Empress Eusebia intervened on his behalf, and he was sent to Athens. (Julian expresses his gratitude to the empress Eusebia in his third oration.[10])
After dealing with the rebellions of Magnentius and Sylvanus, Constantius felt he needed a permanent representative in Gaul. Julian was thus summoned to appear before the emperor in Mediolanum (Milan) and, on 6 November, 355, he was made Caesar of the West and married Constantius' sister, Helena. Constantius, after his experience with Gallus, intended his representative to be more a figurehead than an active participant in events, so he packed Julian off to Gaul with a small retinue and Constantius' prefects in Gaul would keep him in check. Julian, however, had other ideas, taking every opportunity to involve himself in the affairs of Gaul.[11] In the following years Julian learned how to lead and then run an army, through a series of campaigns against the Germanic tribes that had settled on both sides of the Rhine.
In 356 during his first campaign he led an army to the Rhine, engaged the barbarians and won back several towns that had fallen into Frankish hands, including Colonia Agrippina (Cologne). With success under his belt he withdrew for the winter to Gaul, distributing his forces to protect various towns, and choosing the small town of Senon near Verdun to await the spring.[12] This turned out to be a tactical error, for he was left with insufficient forces to defend himself when a large contingent of Franks besieged the town and Julian was virtually held captive there for several months, until his general Marcellus deigned to lift the siege. Relations between Julian and Marcellus seem to have been poor. Constantius accepted Julian's report of events and Marcellus was replaced as magister equitum by Severus.[13][14]
The following year saw a combined operation planned by Constantius to regain control of the Rhine from the Germanic tribes that had spilt across the river onto the west bank. From the south his magister peditum Barbatio was to come from Milan and amass forces at Augst (near the Rhine bend), then set off north with 25,000 soldiers; Julian with 13,000 troops would move east from Reims. However, while Julian was in transit, a group of Laeti attacked Lyon ("Lugdunum") and Julian was delayed in order to deal with them. This left Barbatio unsupported and deep in Alamanni territory, so he felt obliged to withdraw, retracing his steps. Thus ended the coordinated operation against the Germanic tribes.[15][16]
With Barbatio safely out of the picture, King Chnodomarius led a confederation of Alamanni forces against Julian and Severus in a battle that took place in the vicinity of Strasbourg. The Romans were heavily outnumbered[17] and during the heat of battle a group of 600 horsemen on the right wing deserted,[18] yet, taking full advantage of the limitations of the terrain, the Romans were overwhelmingly victorious. The enemy was routed and driven into the river. King Chondmar was captured and later sent to Constantius in Milan.[19][20] Ammianus, who was a participant in the battle, portrays Julian in charge of events on the battlefield[21] and describes how the soldiers, because of this success, acclaimed Julian attempting to make him Augustus, an acclamation he rejected, rebuking them. He later rewarded them for their valor.[22]
Rather than chase the routed enemy across the Rhine, Julian now proceeded to follow the Rhine north, the route he followed the previous year on his way back to Gaul, but at the Mainz bridge he crossed over and made a sudden foray into Alamanni territory, where Roman forces had not been seen for many years, forcing three kings to submit. This action showed the Alamanni that Rome was once again present and active in the area. On his way back to winter quarters in Paris he dealt with a band of Franks that had taken control of some abandoned forts along the Meuse River.[20][23]
In 358, Julian gained victories over the Salian Franks on the Lower Rhine, settling them in Toxandria in the Roman Empire, north of today's city of Tongeren, and over the Chamavi, who were expelled back to Hamaland.
At the end of 357 Julian, with the prestige of his victory over the Alamanni to give him confidence, prevented a tax increase by the Gallic praetorian prefect Florentius and personally took charge of the province of Belgica Secunda. This was Julian's first experience with civil administration. Properly it was a role that belonged to the praetorian prefect. However, Florentius and Julian often clashed over the administration of Gaul. Julian's first priority, as Caesar and nominal ranking commander in Gaul, was to drive out the barbarians who had breached the Rhine frontier. However, he sought to win over the support of the civil population, which was necessary for his operations in Gaul and also to show his largely Germanic army the benefits of Imperial rule. He therefore felt it was necessary to rebuild stable and peaceful conditions in the devastated cities and countryside. For this reason, Julian clashed with Florentius over the latter's support of tax increases, as mentioned above, and Florentius's own corruption in the bureaucracy.
