Theodosius I was Roman emperor of the East from 379 until 395. He was born in 346 at Cauca, Spain and died in 395. The son of the general Theodosius, he served in the army under his father in Britain, and as commander-in-chief at Moesia, defeating the Sarmatians in 374. In 379 he was called to the eastern throne by Gratian, the emperor of the West, just after the defeat of the Romans by the Goths at Adrianople, where the eastern emperor, Valens, had himself been killed. Theodosius I cleared the Balkan peninsular of the Goths. The remainder of his reign was involved with civil war within the Roman empire and the suppression of pagan religion. Research Theodosius I
