A majority of the Burgundians crossed the Rhine in 406/407, together with numerous other Germanic tribes. Their king Gundahar is first attested in 411 as cooperating with Goar, king of the Alans, to proclaim Jovinus as a new emperor in the province Germania Inferior on the lower Rhine. He is attested as being involved in Jovinus's campaigns in southern Gaul. Following Jovinus's defeat in 413, the Roman "magister militum" Constantius settled the Burgundians on the left bank of the Rhine as Roman "foederati". Based on the later heroic tradition, many scholars identify their area of settlement as around Worms, though some scholars have argued in favor of other locations.
