SUCCESSORS OF CONSTANTINE.--Constantine left his empire to his three unworthy sons. _Constantine_, the eldest, had the Western provinces for his share. He endeavored to wrest Italy from his brother _Constans_, but was slain at _Aquileia_ (340). This event left Constans the master of the entire West. He took up his abode in Gaul, where he was slain by _Magnentius_, the leader of a mutinous body of soldiers (350). _Constantius_ was at _Edessa_, engaged in war against the Persians. He marched westward, and routed Magnentius at _Mursia_, in Pannonia. This rival fled to Gaul, and was there attacked and destroyed. _Gallus_, the cousin of Constantius, was put to death for the murder of one of the emperor's officers (354). _Julian_, the brother of Gallus, was the sole remaining survivor of the family from which the emperor sprung. _Constantius_, under whom the whole empire was now for a few years (357-361) united, made a triumphal visit to Rome. He was the defender of the Arians, but he found it impossible to coerce the Roman Christians into the adoption of his opinion. The orthodox bishop whom he had banished, was restored. _Constantius_ was succeeded by his cousin _Julian_ (361-363), commonly called the _Apostate_.
