Regent
Galla Placidia was regent of the Western Roman Empire from 425 to 437, her regency ending when Valentinian reached his eighteenth birthday on July 2, 437. Among her early supporters was Bonifacius, governor of the Diocese of Africa. Aetius, his rival for influence, managed to secure Arles against Theodoric I of the Visigoths. The Visigoths concluded a treaty and were given Gallic noblemen as hostages. The later Emperor Avitus visited Theodoric, lived at his court and taught his sons.
