Julian was a son of Julius Constantius, half-brother of Constantine I (emperor 306 - 337 CE). Three sons of Constantine I -- Constantius II, Constantine II, and Constans -- began to rule the Roman empire after the death of their father. Royal family politics have been awkward throughout much of history, and it seems that two uncles and six cousins of Constantius II were massacred shortly after the death of Constantine I, leaving only the three ruling brothers, together with Gallus, Julian and Nepotianus as surviving male relatives of Constantine I. By 340 CE, Constantine II was also dead. Constans was overthrown in 350 CE; around the same time, Nepotianus managed to rule as emperor in Rome for about a month before being killed. In 351 CE, Constantius II appointed Gallus as Caesar, but had him executed in 354 and eventually appointed Julian as replacement. Family harmony, alas, did not persist forever, and in 361 CE the cousins prepared for war against each other, which was averted only by the sudden illness and death of Constantius II. Julian thus became emperor (361 - 363 CE). Although Julian had been raised a Christian under his grandmother's influence, somewhere around 351 CE he had become a devotee of the sun god, Helios; he nevertheless gave Constantius II a Christian burial in Constantinople. As a pagan, Julian hoped to restore paganism, and Arsacius was his appointment in Galatia. Julian died in his campaign against the Sassanids
Here is his letter (c. 362 CE) to Arsacius:
The charge of "atheism" here springs from the fact that the Jewish temple contained no visible idol to worship and that the Christians had followed this Jewish custom
