  • John F. Matthews


Theodosius I, the son of count *Theodosius(1), was born c. 346 ce. He was promoted early, serving as *dux of *Moesia Superior in 374. On his father's sudden disgrace and execution in 376 he retired to the family properties at Cauca but in 378, after the defeat and death of *Valens at Adrianople, *Gratian appointed him *magister militum to fight the *Goths, and shortly afterwards (19 January 379) proclaimed him Augustus of the eastern parts, including the dioceses of *Dacia and *Macedonia. For the next few years Theodosius conducted campaigns against the Goths, basing himself at first at Thessalonica (379–80), then at Constantinople. Failing to eject the Goths from the empire, on 3 October 382 he signed a treaty with them, recognizing them as federates and assigning them lands in *Thrace and Lower Moesia. In 386 he signed a treaty with Persia, whereby the long-disputed kingdom of Armenia was partitioned between the two empires.
