[Picture: Pol Pot] Saloth Sar, aliases Brother Number One, Pol, Pouk, Hay, Grand-Uncle, '87', Phem, '99, and best known as Pol Pot, was the leader of the communist movement known as the Khmer Rouge. He was the Prime Minister of Cambodia (officially renamed Democratic Kampuchea under his rule) from 1976 to 1979, having been de facto leader since mid-1975. During his time in power Pol Pot imposed a version of agrarian collectivization whereby city dwellers were relocated to the countryside to work in collective farms and forced labour projects, conceived as a restarting of civilization in "Year Zero". The combined effect of slave labour, malnutrition, poor medical care and executions had an estimated death toll of 750,000 to 1.7 million. His regime achieved special notoriety for singling ...more >>out all intellectuals and other "bourgeois enemies" for murder. In 1979, he fled into the jungles of northwest Cambodia after an invasion by neighbouring Vietnam, which led to the collapse of the Khmer Rouge government. Pol Pot was never brought to justice, although he was overthrown and imprisoned by other Khmer Rouge leaders. He died in 1998, from natural causes, while under house arrest.
