Pol Pot (born Saloth Sar 19 May 1925 – 15 April 1998) was a Cambodian communist revolutionary and politician who served as the General Secretary of the Communist Party of Kampuchea from 1963 to 1981. Ideologically a Marxist–Leninist and Khmer nationalist, he led the Khmer Rouge group from 1963 until 1997. From 1976 to 1979, he served as the Prime Minister of Democratic Kampuchea.
Renaming the country Democratic Kampuchea and seeking to create an agrarian socialist society, Pol Pot's government forcibly relocated the urban population to the countryside to work on collective farms. Those regarded as enemies of the new government were killed. These mass killings, coupled with malnutrition, strenuous working conditions, and poor medical care, killed between 1.5 to 3 million people of a population of roughly 8 million (about 25%), a period later termed the Cambodian genocide. Marxist–Leninists unhappy with Pol Pot's government encouraged Vietnamese intervention. In 1978, the Vietnamese invaded Cambodia, toppling Pol Pot's government in 1979. The Vietnamese installed a rival Marxist–Leninist faction opposed to Pol Pot and renamed the country as the People's Republic of Kampuchea. Pol Pot and his Khmer Rouge retreated to a jungle base near the Thai border. Until 1993, they remained part of a coalition internationally recognized as Cambodia's rightful government. The Ta Mok faction placed Pol Pot under house arrest, where he died.
