Events

By place

Roman Empire

• Constantius, Roman general (magister militum), drives the Visigoths out of Gaul. He captures the usurper Priscus Attalus, and sends him under military escort to Ravenna.
• The Visigoths invade the Iberian Peninsula and begin to conquer territory taken previously by the Vandals. King Ataulf and his pregnant wife Galla Placidia leave Gallia Narbonensis; they relocate at Barcelona. Their infant son, Theodosius, dies in infancy, eliminating an opportunity for a Roman-Visigothic line. Ataulf is assassinated in the palace while taking a bath. Sigeric succeeds him, but after a reign of seven days he is also murdered.
• Autumn – Wallia, brother of Ataulf, becomes king of the Visigoths. He accepts a peace treaty with emperor Honorius, in return for a supply of 600,000 measures of grain. After the negotiations he sends Placidia to Rome with hostages.
