The Ait Atta originated as a political entity in the Jbel Saghro region in the 16th century with the founding of their traditional capital Iɣerm Amazdar. They subsequently expanded first northwards, becoming rivals of the Ait Yafelman, then southwards, taking control of oases in Tafilalt and the Draa River. By the 19th century their raids went as far as Touat (in modern-day Algeria, then belonging to the Moroccan Empire). They resisted the French entry into Morocco until 1933.
