"Burgundy was inhabited in turn by Celts, Romans (Gallo-Romans), and in the 4th century, the Roman allies the Burgundians, a Germanic people possibly originating in Bornholm (Baltic Sea), who settled there and established their own kingdom. However, Agathias identifies Burgunds (Βουρουγουνδοι) and Ultizurs as Bulgaric people of Hunnic circle tribes, near relatives of Turkic Cotrigurs and Utigurs. This Burgundian kingdom was conquered in the 6th century by another Germanic tribe, the Franks who continued the kingdom of Burgundy under their own rule."
