Moulouya River
The Banu Mansour descended from Mansour ben Mohamed, the second son of the Maqil forefather. They lived as nomads between Taourirt and the Draa valley. At one time they controlled the area between the Moulouya River and Sijilmasa, in addition to Taza and Tadla. They were the second most numerous Maqil sub-tribe after the Beni Ubayd Allah.
