* Ruanda-Urundi ( Belgium ), from 20 July 1922 to 13 December 1946.

Formerly two separate German protectorates, they were joined as a single mandate on 20 July 1922.

From 1 March 1926 to 30 June 1960, Ruanda-Urundi was in administrative union with the neighbouring colony of Belgian Congo.

After 13 December 1946, it became a United Nations Trust Territory, remaining under Belgian administration until the separate nations of Rwanda and Burundi gained independence on 1 July 1962.
