Kwilu was administered as a province from 1962 to 1966. However, 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.
