Factors that had contributed to the revolt included the arrival of newcomers from the Sankuru District to the east, the use of force to compel labor on the cotton plantations, and the economic downturn of 1931. During the reorganization of 1933 a portion in the east was removed from Lac Léopold II District and added to Kasaï District, while a portion in the west along the Congo River was added to the Bas-Congo District. The smaller Lac Léopold II District was part of the new Léopoldville Province. The district in 1955–1957 was essentially the same as the current Mai-Ndombe Province. It bordered the French possessions to the east, Kwango and Kwilu districts to the south, Kasai District to the west, and Tshuapa and Equateur districts to the north. The area was out of a total of for Leopoldville province as a whole. In the 1960s the province was renamed to Bandundu Province and the district was renamed to Mai-Ndombe District.
