The submission of Guillaume II of Aquitaine, by V. Carducci (17th c.). Madrid, Prado museum

William was son of the Acfred I of Carcassonne and Adelinde, William I's sister and Bernard Plantapilosa's daughter. Immediately after succeeding his uncle, he made war on the Burgundians and Normans, who refused to accept Rudolph as king of France. His support of the king, however, was insincere. He later revolted and Rudolph led an army into Aquitaine, but was called back to defend the Rhine from the Magyars. William died soon after.

In 924 the duke Raoul of Burgundy came up to the Loire river and William was forced to make his submission to him. Upon which Raoul, relieved that such a powerful vassal accepted his suzerainty, gave him back the counties of Berry and Macon and the town of Bourges.[1]
