 Some Burgundians also migrated westwards and settled as "foederati" in the Roman province of Germania Prima along the Middle Rhine.Other Burgundians however remained outside the empire and apparently formed a contingent in Attila's Hunnic army by 451.In 411, the Burgundian king Gundahar (or "Gundicar") set up a puppet emperor, Jovinus, in cooperation with Goar, king of the Alans.
