The Zirids were a Berber dynasty, originating in Petite Kabylie among the Kutama tribe, that ruled Ifriqiya (roughly, modern Tunisia), initially on behalf of the Fatimids, for about two centuries, until weakened by the Banu Hilal and finally destroyed by the Almohads. Their capital was Kairouan. An offshoot branch of the family ruled Granada until 1090.
