Sangiban was a fifth-centuryAlan king at the time ofAttila's invasion ofGaul (451). He was the successor ofGoar as king of the Alanfoederati settled in the region around Aurelianum (modern-dayOrléans). According toJordanes, Sangiban had promised Attila before theBattle of Châlons to open the city gates and deliver Aurelianum to theHuns. Suspecting this, the Romans and Visigoths put Sangiban in the center of the line opposing the Huns, where they could prevent him from defecting. Thus the Alans bore the main brunt of the Hunnic assault, while the Goths were able to flank the Huns and ultimately drive them back.
Jordanes does not record whether Sangiban survived the battle. But in any case, the Alans of Aurelianum were conquered by the Visigoths a few years later and incorporated into theGothic Kingdom of Toulouse.
