Districts of the Belgian Congo
The Districts of the Belgian Congo were the primary administrative divisions when Belgium annexed the Congo Free State in 1908, each administered by a district commissioner. In 1914 they were distributed among four large provinces, with some boundary changes. In 1933 the provinces were restructured into six, again with boundary changes. The number of districts fluctuated between 12 and 26 through splits and consolidations, first rising, then falling, then rising again.
