___ The Gambia

Background:
The Gambia is a strip of land 15 to 30 miles (25 to 50 kilometres) wide and 295 miles long on either bank of the Gambia River; except for a short coastline, it is surrounded by Senegal. Its unusual shape and size are attributable to territorial compromises arising from 19th-century Anglo-French rivalry in western Africa.

After 200 years of British colonial rule The Gambia gained its independence in 1965; it formed a short-lived federation of Senegambia with Senegal between 1982 and 1989.
In 1991 the two nations signed a friendship and cooperation treaty.
A military coup in 1994 overthrew the president and banned political activity, but a 1996 constitution and presidential elections, followed by parliamentary balloting in 1997, completed a nominal return to civilian rule. The country undertook another round of presidential and legislative elections in late 2001 and early 2002.
Yahya A. J. J. JAMMEH, the leader of the coup, has been elected president in all subsequent elections.
Presidential elections were held in the Gambia on 1 December 2016, where opposition candidate ADAMA BARROW defeated long-term incumbent Yahya Jammeh. First Jammeh conceded defeat, but later announced that he was rejecting the results and called for a new election.
