(SANHAJA, SENAJEH), a Berber tribe of southern Morocco who gave their name to Senegal, once their tribal home. They formed one of the tribes which, uniting under the leadership of Yusef bin Tashfin, crossed the Sahara and gave a dynasty to Morocco and Spain, namely, that of the Almoravides. The Zeirid dynasty which supplanted the Fatimites in the Maghrib and founded the city of Algiers was also of Zenaga origin. The Zenaga dialect of Berber is spoken in southern Morocco and on the banks of the lower Senegal, largely by the negro population.
