Patrice Émery Lumumba was a Congolese politician and independence leader who served as the first Prime Minister of the independent Democratic Republic of the Congo from June until September 1960. He played a significant role in the transformation of the Congo from a colony of Belgium into an independent republic. Ideologically an African nationalist and pan-Africanist, he led the Congolese National Movement (MNC) party from 1958 until he was assassinated.
