a historical region in southern Iran. It was known in antiquity as Persis in ancient Greek and as Parsa in Old Persian; Fars is an Arabic form of the latter. In the seventh century the Arabs conquered Fars and destroyed its capital, Istakhr. In the late seventh century the region became a center of the Kharijite movement. Fars served as the nucleus of the states of the Buyid, Salghurid, Muzaffarid, and Zand dynasties, all of which located their capital in Shiraz.
