Libya, country located in North Africa. Most of the country lies in the Sahara desert, and much of its population is concentrated along the coast and its immediate hinterland, where Tripoli (Ṭarābulus), the de facto capital, and Benghazi (Banghāzī), another major city, are located. Libya comprises three historical regions—Tripolitania in the northwest, Cyrenaica in the east, and Fezzan in the southwest. The Ottoman authorities recognized them as separate provinces. Under Italian rule, they were unified to form a single colony, which gave way to independent Libya.
