The Battle of Arles was fought between the Visigoths and a Roman-Hunnic alliance in 425. The Visigoths and the Romans had previously been in peace, but in 425 the Visigothic king Theodoric I broke the peace treaty and invaded Gaul, laying siege to Arles. He was defeated and driven away by the Romans, under the leadership of Flavius Aetius, and their Hunnic allies. Theodoric thereafter made peace again, instead turning his sights on the Vandals in Hispania.
