Zaire, officially the Republic of Zaire, was a state in central Africa from 1971 to 1997. It was, by area, the third-largest country in Africa after Sudan and Algeria, and the 11th-largest country in the world from 1965 to 1991. With a population of over 23 million, Zaire was the most populous Francophone country in Africa. Zaire was strategically important to the West during the Cold War, particularly the U.S., as a counterbalance to Soviet influence in Africa. The U.S. and its allies supported the Mobutu Regime (1965–1997) with military and economic aid to prevent the spread of communism.
The country was a one-party totalitarian military dictatorship, run by Mobutu Sese Seko and his Popular Movement of the Revolution. Zaire was established following Mobutu's seizure of power in a military coup in 1965, after five years of political upheaval following independence from Belgium known as the Congo Crisis. Zaire had a strongly centralist constitution, and foreign assets were nationalized. The period is sometimes referred to as the Second Congolese Republic.
