Before independence from Belgium, Kiwele was a member of the
UMHK-backed
Union congolaise. With his party's delegation, he participated at the
Luluabourg conference in 1959. When Congo gained its independence from Belgium, Kiwele was elected as a provincial MP for the Baudouinville territory, now on a list of
CONAKAT, political party of
Moïse Tshombe and
Godefroid Munongo. Eleven days after Congo's independence, Tshombe declared the independence of
Katanga from the Congo. Kiwele became the Minister of National Education in the government of the new
State of Katanga. Like all Katangese government Ministers, he had a Belgian
chef de cabinet, in his case Marcel Petit. Kiwele composed the national anthem for the state, called
La katangaise ("The Katangan"), in 1960. When Tshombe and Minister of Foreign Affairs
Évariste Kimba were arrested at the Conference of
Coquilhatville at the end of August 1961, Kiwele formed a
triumvirate with Munongo and Finance Minister
Jean-Baptiste Kibwe to temporarily replace Tshombe at the helm of the country. Joseph Kiwele died in Élisabethville on 14 November 1961, aged 49, of a brain
thrombosis. == Legacy ==
