Arcadius, the first of the Byzantine emperors, born in Spain, A. D. 383, died in Constantinople, May 1, 408. He was the elder son of Theodosius the Great, the last ruler of the whole Roman empire. In 395, a few months before his death, Theodosius divided the empire between his two sons, Arcadius and Honorius, giving to the former the eastern part, extend-ing from the Adriatic to the Tigris and from Scythia to Ethiopia. Arcadius ruled at first under the regency of Rufinus, who was soon assassinated at the instigation of his rival, Sti-licho, the regent of Honorius. Eutropius, a eunuch, afterward became regent, and held the place till 399, when Tribigild, a Gothic chief in Phrygia, revolted and compelled Arcadius to put his favorite to death. Trigibild and his tribe also obtained permission to pass the Bosporus and settle on the European side; but being Arians, they were massacred or driven out by the people of Constantinople. In revenge for this the empress Eudoxia, who had now acquired the absolute control over her husband, caused Chrysostoin, the great adversary of Arianism, to be banished to Comana in Pontus (404). Arcadius was a contemptibly feeble man, but of strict religious orthodoxy.
