Northern Basques, organized in the Duchy of Vasconia, collaborated with Franks during campaigns such as the capture of Barcelona in 799 but after the death of Charlemagne in 814, uprisings started anew. The revolt in Pamplona crossed the Pyrenees north and in 816 Louis the Pious deposed the Basque Duke Seguin of Bordeaux for failing to suppress or sympathising with the rebellion, so starting a widespread revolt, led by García Jiménez (according to late traditions, a near-kinsman of Íñigo Arista, to be the first monarch of Pamplona) and newly appointed duke Lupus Centullo (c. 820). Meanwhile, in Aragon the pro-Frankish Count Aznar Galindo was overthrown by Enecco's allied Count Gartzia Malo, with Aznar Galindo in turn seeking refuge in Frankish-held territory. Louis the Pious received the submission of rebel Basque lords in Dax, but things were far from settled.
