The main passes in the Pyrenees were Roncesvalles, Somport and La Jonquera. Charlemagne established across them the vassal regions of Pamplona, Aragon, and Catalonia respectively. Catalonia was itself formed from a number of small counties, including Pallars, Girona, and Urgell; it was called the "Marca Hispanica" by the late 8th century. They protected the eastern Pyrenees passes and shores and were under the direct control of the Frankish kings. Pamplona's first king was Iñigo Arista, who allied with his Muslim kinsmen the Banu Qasi and rebelled against Frankish overlordship and overcame a Carolingian expedition in 824 that led to the setup of the Kingdom of Pamplona. Aragon, founded in 809 by Aznar Galíndez, grew around Jaca and the high valleys of the Aragon River, protecting the old Roman road. By the end of the 10th century, Aragon, which then was just a county, was annexed by Navarre. Sobrarbe and Ribagorza were small counties and had little significance to the progress of the "Reconquista".
