Pol Pot
Saloth Sar (better known as Pol Pot; January 25, 1925 – April 15, 1998) was the dictator of Cambodia between 1975 and 1979. He was widely regarded as one of the most brutal dictators in world history. He was the leader of a group called the Khmer Rouge. They were a group of peasant revolutionaries who turned Cambodia into a military dictatorship officially called Democratic Kampuchea. Between 1.7 and 2.2 million Cambodians were killed by his regime. Pol Pot was thrown out of power in January, 1979, when the Vietnamese communists liberated Kampuchea.
