The Gambia, officially the Republic of The Gambia, is a country in West Africa. It is the smallest country within mainland Africa and is surrounded by Senegal, except for its western coast on the Atlantic Ocean. The Gambia is situated on both sides of the lower reaches of the Gambia River, the nation's namesake, which flows through the centre of the Gambia and empties into the Atlantic Ocean. It has an area of 10,689 square kilometres (4,127 sq mi) with a population of 1,857,181 as of the April 2013 census. Banjul is the Gambian capital and the country's largest metropolitan area. The largest cities are Serekunda and Brikama.The Portuguese in 1455 entered the Gambian region, the first Europeans to do so, but never established important trade there. In 1765, The Gambia was made a part of the British Empire by establishment of the Gambia Colony and Protectorate. In 1965, the Gambia gained independence under the leadership of Dawda Jawara, who ruled until Yahya Jammeh seized power in a bloodless 1994 coup. Adama Barrow became the Gambia's third president in January 2017, after defeating Jammeh in the December 2016 elections. Jammeh initially accepted the results, then refused to accept them, which triggered a constitutional crisis and military intervention by the Economic Community of West African States, resulting in his exile.The Gambia's economy is dominated by farming, fishing, and especially, tourism. In 2015, 48.6% of the population lived in poverty. In rural areas, poverty is even more widespread, at almost 70%.
