Évariste Leon Kimba Mutombo (16 July 1926 – 2 June 1966) was a Congolese journalist and politician who served as Foreign Minister of the State of Katanga from 1960 to 1963 and Prime Minister of the Democratic Republic of the Congo from 13 October to 25 November 1965. Kimba was born in 1926 in Katanga Province, Belgian Congo. Following the completion of his studies he worked as a journalist and became editor-in-chief of the Essor du Congo. In 1958 he and a group of Katangese concerned about domination of their province by people from the neighbouring Kasaï region founded the Confédération des associations tribales du Katanga (CONAKAT), a regionalist political party. In 1960 the Congo became independent and shortly thereafter Moise Tshombe declared the secession of the State of Katanga. Kimba played an active role in the separatist state's government as its Minister of Foreign Affairs and participated in numerous talks with the central government aimed at political reconciliation. Following the collapse of the secession in early 1963, Kimba had a falling out with Tshombe and took up several ministerial posts in the new province of South Katanga. Tshombe was later made Prime Minister of the Congo while Kimba joined the Association Générale des Baluba du Katanga (BALUBAKAT) party. On 13 October 1965 President Joseph Kasa-Vubu dismissed Tshombe and appointed Kimba Prime Minister. Kimba formed a government of national unity and spent the following weeks attempting to achieve rapprochement between the Congo and other African states. However, his government failed to obtain a vote of confidence from Parliament, though Kasa-Vubu reappointed Kimba to the premiership in the face of determined opposition from Tshombe's supporters. On 25 November Army Commander-in-Chief Joseph-Désiré Mobutu launched a coup removing both him and Kasa-Vubu from power and assumed control of the presidency. In May 1966 Mobutu's government accused Kimba of plotting with three other former government ministers to launch a coup. He was executed on 2 June for treason.
