Who were the original Burgundians?

The Burgundians were a large East Germanic tribe, or group of tribes, who lived in the area of modern Poland in the time of the Roman empire.

During the late Roman period, a powerful group of Burgundians and other Vandalic tribes moved westward toward the Roman frontiers along the Rhine Valley, making them neighbors with the Franks to the north, and the Suebic Alemanni to the south. They established themselves in Worms, but with Roman cooperation their descendants eventually established the Kingdom of the Burgundians much further south in the western Alps region, where modern Switzerland, France, and Italy meet. This later became a component of the Frankish empire. The name of this Kingdom survives in the regional appellation, Burgundy, a region in modern France.

Another part of Burgundians stayed in the Oder-Vistula basin and formed a contingent in Attila's Hunnic army by 451.
