Mobutu Sese Seko Kuku Ngbendu Wa Za Banga was a Congolese politician and military officer who was the President of the Democratic Republic of the Congo from 1965 to 1971, and later Zaire from 1971 to 1997. He also served as Chairman of the Organisation of African Unity from 1967 to 1968. During the Congo Crisis, Mobutu, serving as Chief of Staff of the Army and supported by Belgium and the United States, deposed the democratically elected government of nationalist Patrice Lumumba in 1960. Mobutu installed a government that arranged for Lumumba's execution in 1961, and continued to lead the country's armed forces until he took power directly in a second coup in 1965.
To consolidate his power, he established the Popular Movement of the Revolution as the sole legal political party in 1967, changed the Congo's name to Zaire in 1971, and his own name to Mobutu Sese Seko in 1972. Mobutu claimed that his political ideology was "neither left nor right, nor even centre" but in practice he developed a regime that was intensely autocratic even by African standards of his time. He attempted to purge the country of all colonial cultural influence through his program of "national authenticity".
