Theodosius I., the Great

Roman emperor; was the son of Theodosius the Elder, a noted general, whose campaigns in Britain and elsewhere he participated in; marked out for distinction by his military prowess he, in 379, was invited by the Emperor Gratian to become emperor in the East, that he might stem the advancing Goths; in this Theodosius was successful; the Goths were defeated, conciliated, had territory conceded to them, and became in large numbers Roman citizens; rebellions in the Western Empire and usurpations of the throne compelled Theodosius to active interference, which led to his becoming sole head of the empire (394), after successfully combating the revolutionaries, Franks and others; was a zealous Churchman, and stern suppressor of the "Arian Heresy"; the close of his reign marks the beginning of the end of the Roman Empire, for his death opened the floodgates of barbarian invasion, and from this date begins the formation of the new kingdoms of Europe (346-395).
