The Republic of Cameroon is a unitary republic of central Africa. It borders Nigeria, Chad, Central African Republic, Republic of Congo, Gabon, Equatorial Guinea and the Gulf of Guinea. Originally a German colony, it was split after World War I among the French and British. In 1960, French Cameroun became an independent republic, merging with the southern part of British Cameroons in 1961 to form the Federal Republic of Cameroon. It was renamed the United Republic of Cameroon in 1972, and the Republic of Cameroon or République du Cameroun in 1984 (its official languages are English and French). Cameroon has generally enjoyed stability, which has permitted the development of agriculture, roads, and railways, as well as a petroleum industry. Despite movement toward political reform, power remains firmly in the hands of an ethnic oligarchy.
