7. Idi Amin Dada
Idi Amin was an army officer and president of Uganda. He took power in a military coup in January 1971, deposing Milton Obote. His rule was characterized by human rights abuses, political repression, ethnic persecution, extra judicial killings and the expulsion of Indians from Uganda. The number of people killed as a result of his regime is unknown; estimates range from 80,000 to 500,000. On August 4, 1972, Amin issued a decree ordering the expulsion of the 60,000 Asians who were not Ugandan citizens (most of them held British passports). This was later amended to include all 80,000 Asians, with the exception of professionals, such as doctors, lawyers and teachers. Amin was eventually overthrown, but until his death, he held that Uganda needed him and he never expressed remorse for the abuses of his regime.
