Congo-Brazzaville or Republic of the Congo

The Republic of the Congo, also known as Congo-Brazzaville, the Congo Republic or simply either Congo or the Congo is a country located in the western coast of Central Africa. To the west lies Gabon; Cameroon to its northwest and the Central African Republic to its northeast; the Democratic Republic of the Congo to the southeast and the Angolan exclave of Cabinda to its south; and the Atlantic Ocean to its southwest. The official language is French. The region was dominated by Bantu-speaking tribes at least 3,000 years ago, who built trade links leading into the Congo River basin. Congo was formerly part of the French colony of Equatorial Africa. The Republic of the Congo was established on 28 November 1958 and gained independence from France in 1960. It was a Marxist–Leninist state from 1969 to 1992, under the name People's Republic of the Congo.
