The Battle of Pancorbo was a battle that took place in the year 816 between a Moorish army from the Emirate of Cordoba sent by Al-Hakam I and under the control of Abd al-Karim ibn Abd al-Wahid ibn Mugit and the forces loyal to Francia under the control of Balask al-Yalasqi. The battle was fought when the Muslim forces attempted to cross the pass at Pancorbo. The battle resulted in a Muslim victory and was instrumental in the Basque revolt and the establishment of Íñigo Arista of Pamplona as a major player in the contemporary Iberian political scene.
