Murīdūn
The Murīdūn ("disciples") were a Sufi order in al-Andalus that rebelled against the authority of the Almoravid dynasty in 1141 and ruled a taifa based on Mértola in the al-Gharb from 1144 until 1151. The founder and leader of the Murīdūn was Abūʾl-Qāsim Aḥmad ibn al-Ḥusayn ibn Qasī, a convert from Christianity from the city of Silves in the far west of al-Andalus.
