William I of Aquitaine

William I (died July 6, 918), called the Pious, was the Count of Auvergne from 886 and Duke of Aquitaine from 893, succeeding the Poitevin ruler Ebalus Manser. He made numerous monastic foundations, most important among them the foundation of Cluny Abbey on September 11, 910.

William was the son of Bernard II of Auvergne and Ermengard. Sometime before 898, he married the Bosonid Engelberga, daughter of Boso of Provence and Ermengard.

By inheritance, he was the ruler of Auvergne and the Limousin. He conquered Poitou and Aquitaine in 893 on behalf of Ebalus Manser. He kept the latter for himself and was proclaimed duke. His possessions extended from Austrasia to Toulouse and included the Autunois and Mâconnais.

In 910, William founded the Benedictine abbey of Cluny that would become an important political and religious centre. William required no control over the abbey, which he arranged should be responsible directly to the pope (see Clunian reforms). William also nominated Cluny's first abbot, Berno of Baume.

A sign of William's independence of rule in Aquitaine is that he had a "deniers" minted in his own name at Brioude. [Rouche, p 428.] He was buried in the monastery of Saint-Julien there. He had no sons of his own and was succeeded by a nephew, William the Younger, son of his sister Adelinda.
