Roman Emperor - Jovian
Jovian, full name Flavius Claudius Jovianus (AD 331-64) was Roman Emperor from 363-64.
He was prefect of the praetorian guards under Emperor Julian (reigned from 361 to 363), accompanying him on the disastrous campaign against the Persians in which Julian lost his life.
Jovian escaped with the army to the Tigris, and was soon chosen as his successor. He was obliged to conclude a humiliating peace with the Persian king, Shapur II, ceding all Roman territory west of the Tigris River.
A Christian, Jovian revoked Julian's edicts against Christianity, and supported the orthodox (Nicene) creed against the Arian Christians. He rescued from exile Bishop Athanasius, a strong opponent of both paganism and Arianism. At the same time, Jovian protected those who wished to continue in their pagan beliefs.
He had reigned for a little more than seven months when he died from unknown causes at Dadastana, Galatia, on February 17, 364, while he was on his way to Constantinople.
