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.
