The Assassination of Patrice Lumumba

Patrice Émery Lumumba
2 July 1925–17 January 1961
was a Congolese independence leader and the first legally elected Prime Minister of the Republic of the Congo after he helped win its independence from Belgium in June 1960. Only ten weeks later, Lumumba's government was deposed in a coup during the Congo Crisis. He was subsequently imprisoned and murdered in circumstances suggesting the support and complicity of the governments of Belgium and the United States.
