Anbar Governorate is the largest governorate/province in Iraq, located in the west of the country. The name means "granaries" in Arabic, and the Anbar governorate's population consists mostly of Sunni Muslim Arabs of the Dulaim tribe. Because of the large Sunni population, the governorate has been a center of the Iraq War Sunni insurgency, with the cities of Fallujah, Haditha, and the provincial capital of Ramadi being major centers of the insurgency.
