The Battle of Faḥṣ al-Jullāb[a] was fought on Thursday 15 October 1165[b] between the invading Almohads and the king of Murcia, Ibn Mardanīsh.

[1] Ibn Mardanīsh called a general levy and sought the assistance of his Christian allies from the Kingdom of Castile to augment his standing army of salaried troops.

[3] Arab reinforcements, mostly from the Riyāḥ, Athbaj and Zughba clans of the Banū Hilāl, had been brought over from Marrakesh in July.

[5] Battle was met 10 miles (16 km) south of Murcia,[6] near Alhama (al-Ḥamma) at a place called the "merchant's field", Faḥṣ al-Jullāb,[7] in the valley of the Guadalentín.

[3] After the battle, Abū Saʿīd ʿUthmān went to Córdoba while Abū Ḥafṣ ʿUmar took most of the army to Marrakesh, where the caliph rewarded each soldier with a turban, a cloak and a bolt of linen, each cavalryman with 20 gold dīnārs and each leader of the Almohad and Arab troops with 100 gold dīnārs.
