Sapaudia in the context of "County of Maurienne"

The Burgundians (Latin: Burgundiones or less commonly Burgundii) were a Germanic people of the Roman imperial era, who established the powerful Kingdom of the Burgundians within the Roman empire, in what is now western Switzerland and south-eastern France. This kingdom is the source of much later names related to the region of Burgundy, including medieval entities such as the Duchy of Burgundy.

In earlier periods, peoples with the same name were reported by Roman sources to have lived in different parts of what is now Germany and Poland, and there are believed to be connections between at least some of these groups. For one thing, the kingdom's core group were followers of the Gibichung dynasty, who had previously led them as foederati in Roman territory on the Rhine border, probably near Worms in present day Germany. They left the Rhine after the Romans and their Hun allies killed many of the Burgundians along with their king Gundahar in 436, accusing them of rebellion. The death of Gundahar at the hands of the Huns became a central theme in medieval Germanic heroic legend, including the Nibelungenlied (where he is “Günther”) and the Völsunga saga (where he is “Gunnar”). After the remnants resettled in Sapaudia near Lake Geneva in about 443, their territory expanded to include Lyon as a new capital. The entire kingdom was incorporated into the Frankish empire in 534.

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. After this, the Burgundians were able to expand their territories and their role in the Roman empire, and they moved their capital from Geneva to Lyon. In 534, the rule of the Burgundian kings ended and the kingdom became part of Francia.

The kingdom grew out of the 443 Imperial Roman resettlement of allied Burgundians to the region of Sapaudia, which at that time included Lake Geneva. These Burgundians were built around the remnants of a previous Roman-allied Burgundian kingdom which the Romans had allowed to settle on the western bank of their Rhine border at Borbetomagus, probably near Worms, having previously been Roman allies living east of the Rhine, outside the empire. The tribal ruler who was responsible for this move was Gundahar. In about 436, Gundahar and many of the people he led were killed by the Roman military leader Flavius Aetius working with his Hun allies.
