Burgundian Kingdom
The Kingdom of the Burgundians, or First Kingdom of Burgundy, was one of the so called "barbarian kingdoms" of the late Western Roman Empire in the fifth and sixth centuries. It began in what is now western Switzerland and southeastern France, and was ruled by Burgundian kings who were successors of the older House of Gibichung, but also held office as Roman military officers. In 451, the Burgundians helped the Roman-led allies defeat Attila at the Battle of the Catalaunian Plains, and in 455, they helped Roman-mandated forces led by Theodoric II, king of the Visigothic Kingdom, to defeat the Kingdom of the Suebi.
