In July 1960, there were six provinces in the Belgian Congo: Leopoldville Province, Equateur Province, Province Orientale, Kivu Province, Katanga Province, and Kasai Province. Kivu Province existed from 1933 to 1962 (under the name Province de Costermansville until 1947, from the name of its capital) and from 1966 to 1988.
There are currently ten provinces and one city-province in the Democratic Republic of the Congo:

Article 2 of the 2005 Congolese Constitution, which came into effect on 18 February 2006, specifies twenty-five new provinces while retaining the capital city/province of Kinshasa. This new territorial organization was scheduled to take effect within thirty-six months of the new constitution's promulgation. It did not.
