عبد المؤمن بن علي
Historically, Doukkala referred to a Berber tribe which occupied the territory from Anfa (Casablanca) to Asfi. They revolted against Almohad kings in the 12th century. About 1160, the Almohad ruler Abd al-Mu'min settled Arab bedouin tribes there, a coalition of whom he had defeated earlier in Tunisia.
