The Battle of Faḥṣ al-Jullāb was fought on Thursday 15 October 1165 between the invading Almohads and the king of Murcia, Ibn Mardanīsh. An Almohad army under sayyids Abū Ḥafṣ ʿUmar and Abū Saʿīd ʿUthmān, the brothers of the Caliph Abū Yaʿḳūb Yūsuf, went on the offensive against Ibn Mardanīsh in the summer of 1165. They captured Andújar in September, harried Galera, Caravaca, Baza and Sierra de Segura, then captured Cúllar and Vélez on their approach to Murcia.
