Cameroon (; French: Cameroun), officially the Republic of Cameroon (French: République du Cameroun), is a country in Central Africa. It is bordered by Nigeria to the west; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon and the Republic of the Congo to the south. Cameroon's coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean.
French and English are the official languages of Cameroon. The country is often referred to as "Africa in miniature" for its geological and cultural diversity. Natural features include beaches, deserts, mountains, rainforests, and savannas. The highest point at almost 4,100 metres (13,500 ft) is Mount Cameroon in the Southwest Region of the country, and the largest cities in population-terms are Douala on the Wouri river, its economic capital and main seaport, Yaoundé, its political capital, and Garoua. After independence, the newly united nation joined the Commonwealth of Nations, although the vast majority of its territories had previously been a German colony and, after World War I, a French mandate. The country is well known for its native styles of music, particularly makossa and bikutsi, and for its successful national football team.
Early inhabitants of the territory included the Sao civilisation around Lake Chad and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century and named the area Rio dos Camarões (Shrimp River), which became Cameroon in English. Fulani soldiers founded the Adamawa Emirate in the north in the 19th century, and various ethnic groups of the west and northwest established powerful chiefdoms and fondoms. Cameroon became a German colony in 1884 known as Kamerun.
After World War I, the territory was divided between France and the United Kingdom as League of Nations mandates. The Union des Populations du Cameroun (UPC) political party advocated independence, but was outlawed by France in the 1950s, leading to the Cameroonian Independence War. It waged war on French and UPC militant forces until 1971. In 1960, the French-administered part of Cameroon became independent as the Republic of Cameroun under President Ahmadou Ahidjo. The southern part of British Cameroons federated with it in 1961 to form the Federal Republic of Cameroon. The federation was abandoned in 1972. The country was renamed the United Republic of Cameroon in 1972 and the Republic of Cameroon in 1984.
Cameroon experiences relatively high political and social stability. This has permitted the development of agriculture, roads, railways and large petroleum and timber industries. Large numbers of Cameroonians live as subsistence farmers, however. Since 1982 Paul Biya has been President, governing with his Cameroon People's Democratic Movement party. The country has experienced tensions coming from the English-speaking territories. Politicians in the English-speaking regions have advocated for greater decentralisation and even complete separation or independence (as in the Southern Cameroons National Council) from Cameroon.
