Ruler of British Empire: Idi Amin

The six foot for inch former boxer was welcomed warmly at first when he seized power in Kampala, but the happiness quickly turned to horror. This terrible dictator persecuted ethnic minorities, confiscated the property of Asians and Europeans, and killed as many as 500 million people. However Amin is still best remembered for his eccentricities. He renamed Africa's Lake Edward after himself, declared himself conquerer of the British empire and king of Scotland when the United Kingdom broke off diplomatic ties, and planned about invading Israel. He was a convinced polygamist who married seven women and killed many other for not accepting his generous offers as lover. He was a good friend of almost all infamous dictators of Africa including  Muammar al-Gaddafi who even helped him with troops. He was never judged or convicted but died in his bed on 16 August 2003 at age of 78 after he suffered a kidney failure.
