Ibn Tumart
On the advice of one of his followers, Omar Hintati, a prominent chieftain of the Hintata, Ibn Tumart abandoned his cave in 1122 and went up into the High Atlas, to organize the Almohad movement among the highland Masmuda tribes. Besides his own tribe, the Hargha, Ibn Tumart secured the adherence of the Ganfisa, the Gadmiwa, the Hintata, the Haskura, and the Hazraja to the Almohad cause. Around 1124, Ibn Tumart erected the ribat of Tinmel, in the valley of the Nfis in the High Atlas, an impregnable fortified complex, which would serve both as the spiritual center and military headquarters of the Almohad movement.
