As a consequence of the crisis of AD 455 (the fall of the Emperor Petronius Maximus and the accession of Avitus, supported by the Visigoths of Theodoric I in Gaul, the sack of Rome by Vandals) the Suevi started raids on the Roman provinces of Carthaginensis and Tarraconensis in Spain. In response, Avitus dispatched Gothic foederati to fight with the Suevi. The Visigoths won the battle of Obrigo in AD 456 and then sacked the Suevic capital city of Braga in Galicia (Muhlberger 1990: 224–27).
