Haile Selassie I
In 1936, he left Ethiopia after an invasion by Benito Mussolini's Italy. The Emperor gave a speech at the League of Nations that asked the world to stop the Italians, but it failed to act. With the help of the British in World War II, he returned to Ethiopia in 1941. In 1963, the Emperor did everything he could to help start the Organisation of African Unity (OAU), with its headquarters in Addis Ababa. In 1966, he visited Jamaica, where he met the Rastafarian community of Jamaica.
