Banu Qasi
Origins
The Banu Qasi claimed descent from a Visigothic count called Cassius who converted to Islam after the conquest of 711 to 714, keeping his lands in the upper Ebro valley. As muwallads, native Muslims, they became the leading family of the Upper March, based at Tudela.
Rule and society
They balanced between Córdoba, the Franks and the Christian kingdoms, intermarrying with the Arista family of Pamplona, whose founder Íñigo Arista was a half-brother of Musa ibn Musa. Musa ruled Tudela, Zaragoza and Huesca and was called the third king of Spain, until Ordoño I of Asturias defeated him at Albelda in 859. Later family members fought Córdoba, the Tujibids and Navarre.
Decline and legacy
Weakened by family divisions and wars with Sancho Garcés I of Pamplona, the dynasty lost Tudela and its lands. Abd al-Rahman III ended its power in the 920s, and the Tujibid family took over the Upper March.
