Odo died c. 735, leaving his realm to his son Hunald, who desiring the former independence which had been his father's, attacked Martel's successors, starting a war which was to last for two generations. In 743, the situation was further complicated by the arrival of Asturian forces attacking Vasconia from the west. In 744, Hunald abdicated to his son Waifer, who repeatedly challenged Frankish overlordship. After a campaign against the Umayyads in Septimania, the king Pepin the Short turned his attention to Aquitaine and Waifer, unleashing a devastating war on Aquitaine (Vasconia included) that was to have dire consequences on its population, towns and society. Waifer and his Basque troops confronted Pepin several times but were defeated thrice in 760, 762, and 766, after which Aquitaine and Vasconia pledged loyalty to Pepin and Waifer was eventually murdered by desperate followers, or possibly by someone bribed by Pepin.
