Saloth Sar (May 19; 1928-April 15; 1998); better known as Pol Pot; was the leader of the Cambodian communist movement known as the Khmer Rouge and Prime Minister of Democratic Kampuchea from 1976-1979. In 1979; after the invasion of Cambodia by Vietnam; Pol Pot fled into the jungles of southwest Cambodia. Pol Pot died in 1998 while held under house arrest by the Ta Mok faction of the Khmer Rouge.

The Khmer Rouge; or Communist Party of Kampuchea; ruled Cambodia from 1975 to 1979; led by Pol Pot; Nuon Chea; Ieng Sary; Son Sen and Khieu Samphan. It is remembered primarily for its brutality and policy of social engineering which resulted in millions of deaths. Its attempts at agricultural reform led to widespread famine; while its insistence on absolute self-sufficiency; even in the supply of medicine; led to the deaths of thousands from treatable diseases (such as malaria). Brutal and arbitrary executions and torture carried out by its cadres against perceived subversive elements; or during purges of its own ranks between 1976 and 1978; are considered to have constituted a genocide. Several former Khmer Rouge cadres are currently on trial for war crimes in Phnom Penh.
