The Burgundians' tradition of Scandinavian origin finds support in place-name evidence and archaeological evidence (Stjerna) and many consider their tradition to be correct (e.g. Early Roman sources considered them simply another East Germanic tribe.
In 411 AD, the Burgundian king Gunther (or Gundahar or Gundicar) in cooperation with Goar, king of the Alans, set up Jovinus as a puppet emperor.
Under the pretext of Jovinus' imperial authority, Gunther settled on the western (i.e., Roman) bank of the Rhine, between the river Lauter and the Nahe, seizing the settlements of Borbetomagus (present day Worms), Speyer, and Strasbourg.
When Gunderic died in 473, his kingdom was divided between his four sons: Gundobad (473–516 in Lyon, king of all of Burgundy from 480), Chilperic II (473–493 in Valence), Gundomar/Godomar (473–486 in Vienne) and Godegisel (473–500, in Vienne and Geneva).
After the fall of the Roman Empire in 476, King Gundobad allied with the mighty Frankish king Clovis I against the threat of Ostrogoth Theoderic the Great.
