Constantius II in Roman Biography Constantius [Fr. Constance, k6N'stdNs'] H., (Flavius Julius,) the third son of Constantine I., Emperor of Rome, was born at Sirmium in 317 A.D. By his father's will he inherited the Asiatic provinces and Egypt in 337. It is said that he ordered or permitted the massacre of his father's nephews, brother, etc. at the time of his accession. During nearly all his reign he was at war with the Persians, by whom he was often defeated. In 350 the revolt of Magnentius resulted in the death of Constans, Emperor of the West. Constantius turned his arms against Magnentius, whom he defeated at Mursa, on the Drave, in 351, and in Gaul in 353, after which he was master of the whole empire. In 355 he appointed his cousin Julian, Caesar and commander in Gaul, and in 357 visited Rome for the first time. He favoured the Arians, and banished the orthodox bishops. Julian having been proclaimed emperor by his army in Gaul, Constantius was marching to attack him, when he died near Tarsus in 361, and was succeeded by Julian. His reputation is not high either for talents or for virtue. See Eusebius, " Vita Constantii :" Tiixemont, "Histoire des Empereurs ;" Gibbon, " Decline and Fall of the Roman Empire."

The second son of Constantine I and Fausta, he ascended to the throne with his brothers Constantine II and Constans upon their father's death. In 340, Constantius' brothers fought over the western provinces of the empire. Constans defeated his brother and ruled the west for a decade until the usurper Magnentius rebelled in 350. Constans was promptly assassinated, leaving Constantius as the only surviving son of Constantine. After defeating Magnentius at the Battle of Mursa Major and Mons Seleucus, his subsequent suicide left Constantius sole ruler of the empire. His military campaigns against Germanic tribes were successful: he defeated the Alamanni in 354, and campaigned across the Danube against the Quadi and Sarmatians in 357. In the east however, he fought the Sassanids for two decades with mixed success. Constantius elevated his cousin Julian to co-emperor in 355, but by spring 361 the two emperors were at war. However, Constantius died before the two could face each other in battle, naming Julian his successor...
