This is an analysis of the powerful Islamic religious movement, initiated by Ibn T¿±mart among the Berber tribesmen of North Africa, which culminated in the creation of the huge Almohad empire in the twelfth century. Professor Le Tourneau presents his reflections on the place of the movement in history as well as on its influence in present-day Africa. His principal aim is to elucidate how the Almohads managed to unite all of North Africa and Spain in one empire, and why they ultimately failed to hold their empire together. He also shows that some of the essential factors in Almohad society are still influential in Africa today and that the Almohad experience can aid contemporary promoters of North African unity and prevent them from repeating the mistakes of the twelfth-century rulers.
