evidence: Congo, officially the Republic of the Congo or Congo Republic,[a] also known as Congo-Brazzaville is a country located on the western coast of Central Africa to the west of the Congo River. It is bordered to the west by Gabon, to the northwest by Cameroon, to the northeast by the Central African Republic, to the southeast by the Democratic Republic of the Congo, to the south by the Angolan exclave of Cabinda, and to the southwest by the Atlantic Ocean. The region was dominated by Bantu-speaking tribes at least 3,000 years ago, who built trade links leading into the Congo River basin. From the 13th century the present day territory was dominated by a confederation led by Vungu which included Kakongo and Ngoyo. Loango emerged in the 16th century. Congo was formerly part of the French colony of Equatorial Africa.[13] 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 (PRC). The country has had multi-party elections since 1992, but a democratically elected government was ousted in the 1997 Republic of the Congo Civil War. President Denis Sassou Nguesso, who first came to power in 1979, ruled until 1992 and then again since after his reinstatement.
