Idi Amin was the commander of the Ugandan Army when he seized power in a military coup in 1971. He ruled Uganda for eight years, during which time he earned the nickname "The Butcher of Uganda" for his brutality.
According to Amnesty International, Amin was responsible for the death of 500,000 people during his rule. He engaged in ethnic purging of the Acholi and Lango people throughout Uganda and in his own army, as he was constantly paranoid about being overthrown.
After the United Kingdom shuttered its embassy in 1977 because of Amin's oppression, the dictator declared that he had single-handedly defeated the British Empire. He later declared himself, "His Excellency, President for Life, Field Marshal Al Hadji Doctor Idi Amin Dada, VC, DSO, MC, Lord of All the Beasts of the Earth and Fishes of the Seas and Conqueror of the British Empire in Africa in General and Uganda in Particular."
