In 1933 the original four provinces of the Belgian Congo were reorganized into six provinces, named after their capitals, and the central government assumed more control.

[1] Équateur Province became Coquilhatville, with its districts reducing to 15.

[6] The area was 101,500 square kilometres (39,200 sq mi) out of a total of 402,100 square kilometres (155,300 sq mi) for Equateur province as a whole.

On 11 July 2015 Équateur was split into the present provinces of Équateur, Mongala, Nord-Ubangi, Sud-Ubangi and Tshuapa.
