The Barbarian Invasions.
The Migration Period in Europe, 395-527 A. D.
ON the death of THEODOSIUS THE GREAT, in 395 A.D., the Empire was divided between his sons. Flavius Arcadius taking the eastern, Flavius Honorius the western, half. Four Prefectures have now become a fixed territorial division; the realm of Honorius embraces the Prefectures of Gaul and Italy, that of Arcadius the Prefectures of Illyricum (Illyria) and the East (The Diocese of Western Illyricum belongs to the Prefecture of Italy.). About the same time the invasion of Greece by the Visigoths under Alaric I (396 A. D.) began the series of movements which resulted in the breaking up of the western half of the Empire into German kingdoms-the great historical feature of the fifth century.
