 In 1911, the Germans helped the Tutsi put down a rebellion of Hutu in the northern part of Rwanda who did not wish to submit to central Tutsi control.At the end of WWI, Belgium accepted the League of Nations Mandate of 1916 to govern Rwanda as one of the two kingdoms making up the territory Ruanda-Urundi, along with its existing Congo colony to the west.The portion of the German territory, never a part of the Kingdom of Rwanda, was stripped from the colony and attached to Tanganyika, which had been mandated to the British.
