Idi Amin Dada was the third President of Uganda from 1971 to 1979. Amin joined the British colonial regiment, the King's African Rifles, in 1946, serving in Somalia and Kenya. Eventually, Amin held the rank of Major general in the post-colonial Ugandan Army and became its Commander before seizing power in the military coup of January 1971, deposing Milton Obote. He later promoted himself to field marshal while he was the head of state.
Amin's rule was characterised by human rights abuse, political repression, ethnic persecution, extrajudicial killings, nepotism, corruption, and gross economic mismanagement. The number of people killed as a result of his regime is estimated by international observers and human rights groups to range from 100,000 to 500,000.
During his years in power, Amin shifted in allegiance from being a pro-Western ruler enjoying considerable Israeli support to being backed by Libya's Muammar Gaddafi, the Soviet Union and East Germany. In 1975, Amin became the Chairman of the Organisation of African Unity, a Pan-Africanist group designed to promote solidarity of the African states. During the 1977–1979 period, Uganda was a member of the United Nations Commission on Human Rights. In 1977, when Britain broke diplomatic relations with Uganda, Amin declared he had defeated the British and added "CBE", for "Conqueror of the British Empire," to his title. Radio Uganda then announced his entire title: "His Excellency President for Life, Field Marshal Alhaji Dr. Idi Amin Dada, VC, DSO, MC, CBE".
