Idi Amin was already fairly notorious by 1971. As the commander in cheif of Uganda’s armed forces, he had recruited heavily amongst tribes not sympathetic to the Ugandan majority, and built himself a considerable power base. The Ugandan Prime Minister, Milton Obote – formerly an ally to Amin, but now worried about his subordinate’s increasingly obvious ambitions – reclaimed that post in October 1970, reducing Amin in rank to commander in cheif of the army.
In January 1971, Amin struck back. In a lightning military coup, he seized power on January 25. Publically, Amin announced that he was a soldier, not a politician. He promised that his military government would be only a caretaker regime until new elections could be held, and to release all political prisoners. On February 2, he proclaimed himself President of Uganda, a post which he held until he too was deposed, in 1979, after years of corruption, ethnic cleansing and economic mismanagement.
