Unrest and rebellion plagued the government until 1965, when Lieutenant General Mobutu seized control of the country and declared himself president for five years. Mobutu quickly consolidated his power and was elected unopposed as president in 1970. Embarking on a campaign of cultural awareness, Mobutu renamed the country the Republic of Zaire and required citizens to adopt African names. Relative peace and stability prevailed until 1977 and 1978 when Katangan rebels, based in Angola, launched a series of invasions into the Shaba (Katanga) region. The rebels were driven out with the aid of Belgian paratroopers.
During the 1980s, Zaire remained a one-party state. Although Mobutu successfully maintained control during this period, opposition parties, most notably the Union pour la Démocratie et le Progrès Social (UDPS), were active. Mobutu's attempts to quell these groups drew significant international criticism.
As a Zaire's ruler, Mobutu perfected a system of rule by theft (called kleptocracy), where he pillaged the public sector, harassed or jailed those who objected. In some years he and his cronies siphoned off up to 50% of Zaire’s capital budget as well as hundreds of millions in mineral export revenues, foreign aid and loans, and private investment (some guaranteed by the U.S. Eximbank). The effects were catastrophic. Despite vast mineral wealth (diamonds, cobalt, copper), oil deposits, and immense hydroelectric and agricultural potential, Zaire’s per capita income has dropped almost two-thirds since independence in 1960 and is listed as the lowest of all 174 countries in the UNDP’s 1996 Human Development Report.
Mobutu’s impact on people’s daily lives was devastating. Extensive corruption crippled public services, from repairing roads to running schools and hospitals. Workers, their salaries stolen, were forced into the system of corruption just to survive. Nurses sometimes demanded payment before giving shots, while soldiers and police routinely extorted bribes from passersby.

Nevertheless, the U.S. continued to view Mobutu as a useful ally against both global communism and radical African movements. He was vital to the U.S.-backed UNITA rebels’ efforts to overthrow the leftist MPLA government in neighboring Angola.
As the Cold War came to a close, internal and external pressures on Mobutu increased. In late 1989 and early 1990, Mobutu was weakened by a series of domestic protests, by heightened international criticism of his regime's human rights practices, by a faltering economy, and by government corruption, most notably his massive embezzlement of government funds for personal use. In fact, the term “kleptocracy”, or rule by thieves, derives its origins from the Mobutu regime.
Mobutu was finally overthrown by rebels and Rwandan forces in 1997.
