The Burgundians 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. The kingdom ended when it was incorporated into the Frankish empire in 534. It is the source of later names related to the region now known as Burgundy, including medieval entities such as the Duchy of Burgundy. In earlier periods, Burgundians were also reported by Roman sources to have lived in regions now within Germany and Poland, and there are probably connections between these and the later Burgundian kingdom.
