 In all, eight Burgundian kings of the house of Gundahar ruled until the kingdom was overrun by the Franks in 534.As allies of Rome in its last decades, the Burgundians fought alongside Aëtius and a confederation of Visigoths and others against Attila at the Battle of Châlons (also called "The Battle of the Catalaunian Fields") in 451.The alliance between Burgundians and Visigoths seems to have been strong, as Gundioc and his brother Chilperic I accompanied Theodoric II to Spain to fight the Sueves in 455.
