Belgian Empire

The Kingdom of Belgium controlled several territories and concessions during the colonial era, principally the Belgian Congo (modern DR Congo) from 1908 to 1960, Ruanda-Urundi (modern Rwanda and Burundi) from 1922 to 1962, and the Lado Enclave (modern Central Equatoria province in South Sudan) from 1894 to 1910. It also had small concessions in Guatemala (1843–1854) and Belgian concession of Tianjin in China (1902–1931) and was a co-administrator of the Tangier International Zone in Morocco.

Roughly 98% of Belgium's overseas territory was just one colony (about 76 times larger than Belgium itself) – known as the Belgian Congo. The colony was founded in 1908 following the transfer of sovereignty from the Congo Free State, which was the personal property of Belgium's king, Leopold II. The violence used by Free State officials against indigenous Congolese and the ruthless system of economic extraction had led to intense diplomatic pressure on Belgium to take official control of the country. Belgian rule in the Congo was based on the "colonial trinity" (trinité coloniale) of state, missionary and private company interests. During the 1940s and 1950s, the Congo experienced extensive urbanization and the administration aimed to make it into a "model colony". As the result of a widespread and increasingly radical pro-independence movement, the Congo achieved independence, as the Republic of Congo-Léopoldville in 1960.
