Fezzan, a Turkish province (since 1842) to the south of, and politically attached to, Tripoli. Extending some 390 miles N. and S., and 300 E. and W., between 24° and 29° N. lat. and 12° and 18° E. long., Fezzan belongs to the desert region of North Africa. It consists of a huge depression, fenced in on all sides except the west by ranges of hills (2000 to 3000 feet high), and traversed by barren, stony, shelterless plateaus, between which lie long shallow valleys, containing numerous fertile oases. The entire region slopes gently towards the east. The oases, mostly depressions in the valleys, are the only cultivated spots, where a little grain and a few vegetables are raised, and where grows the date-palm, the principal source of food. The climate is on the whole uniform and healthy, although malarial fever is very frequent. Fezzan is both hotter in summer and colder in winter than Tripoli; its temperature ranges from 23° to 112°, the annual mean being 70° F. The atmosphere is very dry; rain scarcely ever falls. There is no export trade except in soda, obtained from extensive salt lakes north-west of Murzuk. The 50,000 inhabitants are a mixed race. They are immoral and idle, but honest and good-natured. In religion they are Sunnite Mohammedans. The principal town is Murzuk (pop. 6500).
