The Hammadids were a Sanhaja Berber dynasty who ruled an area roughly corresponding to north-eastern modern Algeria for about a century and a half (1008–1152), until they were destroyed by the Almohads. Soon after coming to power, they rejected the Ismaili doctrine of the Fatimids, and returned to Maliki Sunnism, acknowledging the Abbasids as rightful Caliphs.
