ثورة البربر
From 937, Abu Yazid began to openly preach holy war against the Fatimids. His movement was the spiritual heir to a number of tendencies endemic in the Maghreb: the Ibadi movement, with its anti-Arab and pro-Berber chauvinism and its insistence that leadership belonged to the "best Muslim", in marked contrast to the Fatimids' claims to a hereditary imamate; the anti-imperial traditions of the great Berber Revolt against the Umayyad Caliphate in 740; and the strong messianic traditions of the Maghreb, which had welcomed and sheltered the Alids persecuted by the Abbasid Caliphate, and which would recur throughout history, culminating in the messianic empire of the Almohads.
