Very good stamp.
Leopold, king of Belgium, took possession of Katanga and on 15 April 1891 its administration was entrusted to Leopold's companies, the Compagnie du Katanga. No effective administration was set up until 19 June 1900, when it was renamed the Comité Spécial du Katanga, an administrative entity separate from the CFS. The Luba people resisted, most notably in a major rebellion in 1895, after which many Luba were sent to work as forced labor in the copper mines of Katanga. Kasongo Nyembo led another rebellion of the Luba that was not suppressed by the Belgians until 1917. After the take-over of Congo from Leopold by the Belgian government, on 1 September 1910, Katanga was integrated into the Belgian Congo but retained a large measure of autonomy until 1 October 1933, when part of its Lomami Province was transferred to Kasaï Province.
