Under the constitution of 18 February 2006, Kwilu District was scheduled to be combined with the city of Kikwit to become Kwilu Province, one of the 25 new provinces into which the DRC would be divided by February 2009. Kikwit would be a capital of the new province. As of July 2011 this decentralization had not happened.
Kwilu was a province from 1962 to 1966, but in 1964 the administration was taken over by the central government due to a rebellion in southwestern Congo. A rebel administration under Pierre Mulele ran most of Kwilu province from January 1964. The province was reconquered by the legal government in June 1965. The provincial government was restored on January 18, 1966, but the province was merged with Kwango District and Mai-Ndombe District to create Bandundu province.
