Historic region, southwestern Libya. A part of the Sahara, most of its inhabitants dwell in oases in the interior. Central and southern Fezzan are noted for the cultivation of date palms, which cover several hundred thousand acres scattered in numerous oases. It was conquered by the Romans in the 1st century BC and by the Arabs in the 7th century AD. The Ottomans made it part of their empire in 1842. Fezzan was amalgamated with Tripolitania and Cyrenaica by the Italians in 1912, and it later became a province of the United Kingdom of Libya (1951–63). Thereafter it was part of Libya.
