Theodosius proclaimed his two sons, Arcadius and Honorius, ''augusti'' earlier during his life, and with his death Arcadius became emperor of the eastern half of the empire and Honorius emperor of the western half. Theodosius died in Milan on [[January 17]], 395. St [[Ambrose of Milan|Ambrose]], with whom Theodosius had a close relationship, preached his funeral oration ("De obitu Theodosii", P. L., XVI, 1385). With the division of the empire between his sons, his death was a milestone in history: The Roman world was never again to be united.
