Constantius II

Constantius II was the second son of Constantine I and one of the longest-reigning emperors of the fourth century, ruling the eastern half of the empire from 337 and the whole empire from 353 until his death in 361. He reunified the empire by 353 after defeating the usurper Magnentius at the Battle of Mursa Major in 351. Constantius II was a committed Arian Christian, using his imperial authority aggressively to promote Arianism. He appointed his cousin Julian as Caesar in 355 to manage the western provinces. When Constantius attempted to redeploy Julian's troops eastward in 360, the army proclaimed Julian Augustus. As Constantius marched west to confront this usurpation, he fell ill and died in Cilicia in November 361 at the age of forty-four.
