The Almohad Caliphate (British English /almə(ʊ)ˈhɑːd/, U.S. English /ɑlməˈhɑd/; Berber: Imweḥḥden, from Arabic الموحدون al-Muwaḥḥidun, "the monotheists" or "the unifiers") was a Moroccan Berber Muslim movement founded in the 12th century.

The Almohad movement was started by Ibn Tumart among the Masmuda tribes of southern Morocco. The Almohads first established a Berber state in Tinmel in the Atlas Mountains in roughly 1120. They succeeded in overthrowing the ruling Almoravids in governing Morocco by 1147, when Abd al-Mu'min al-Gumi (r. 1130–1163) conquered Marrakech and declared himself Caliph. They then extended their power over all of the Maghreb by 1159. Al-Andalus followed the fate of North Africa and all Islamic Iberia was under Almohad rule by 1172.
