The hill country in the interior of western Libya, south of Tripoli. The district was in the hands of a group of Kharijite Imams of the Ibadhiyah sect during the 8th through 10th centuries CE. The Kharijites ("Withdrawers", "Seceders") are Muslims who rejected both Sunni and Shi'ite interpretations of Caliphate succession and developed an idealist and deed-oriented version of Islam. The Ibadhiyah are the moderate wing of the Kharijtes, as opposed to the radical Azariqah movement of Basra, in Iraq.
