Career
Aznar has been confused with Aznar Sánchez, Duke of Gascony, and some authorities have even considered the two like-named contemporaries to be one and the same person. Aznar succeeded Aureolus as count of the valley of the River Aragón on the latter"s death in 809. Some sources indicate him as count of Jaca, which was probably the seat of his authority within the valley.
He was installed by king Louis the Pious (a son of emperor Charlemagne), and remained a Frankish vassal.
He took refuge in the Vasconia that remained suzerain to the Franks, and was appointed count in Urgel and Cerdagne. He had four children:
Matrona, who married García the Bad, but was repudiated when he overthrew her father
Centullo, murdered by his brother-in-law García the Bad
Galindo Aznárez I, later Count of Aragon.
