Julius Constantius

Julius Constantius (died September 337) was a politician of the Roman Empire and a member of the Constantinian dynasty, being a son of Emperor Constantius Chlorus and his second wife Flavia Maximiana Theodora, a younger half-brother of Emperor Constantine I and the father of Emperor Julian.

Julius Constantius was born after 289, the son of Constantius Chlorus and his wife Theodora, adoptive daughter of emperor Maximian. He had two brothers, Dalmatius and Hannibalianus, and three sisters, Constantia, Anastasia and Eutropia. Emperor Constantine I was his half-brother, as he was the son of Constantius and Helena. Despite this illustrious kinship Julius Constantius was never himself emperor or co-emperor; Constantine, however, gave him the title of Patricius.

Julius Constantius was married twice. With his first wife, Galla, sister of the later consuls Vulcacius Rufinus and Neratius Cerealis, he had two sons and a daughter. His eldest son, whose name is not recorded, was murdered in 337 together with his father. His second son Constantius Gallus, was appointed Caesar by his cousin Constantius II. His daughter was the first wife of Constantius II. It has been proposed that Galla and Julius had another daughter, born between 324 and 331 and married to Justus, mother of Justina, whose daughter, wife of Emperor Theodosius I, was called Galla.
