List of colonial governors of Ruanda-Urundi
Wikimedia list article
This is a list of European colonial administrators responsible for the territory of Ruanda-Urundi, an area equivalent to modern-day Rwanda and Burundi. Ruanda-Urundi formed part of German East Africa until it was captured by Belgian forces during World War I. After that, the territory became a League of Nations mandate, and later a United Nations trust territory, under Belgian control, until 1962 when the constituent parts of the territory became independent.
