8. Idi Amin
Responsible for the death of roughly 300,000 civilians, tens of thousands of white missionaries, and the downfall of Uganda’s economy after these atrocities, along with expelling the entire Asian population, Idi Amin was not a cool cucumber.
He was also very mentally unstable, exhibiting many signs of bipolar disorder. He would be happy and charming one minute, then maniacal and cannibalistic the next – yes, it is a widespread belief that he ate people.
Amin lied to his country and said that he had conquered the United Kingdom, after they cut off all diplomatic ties. After reporting that victory, his self-appointed title “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” became a little longer.
