Pol Pot

==== Purges and executions ====
The Khmer Rouge also classified people based on their religious and ethnic backgrounds. Under the leadership of Pol Pot, the Khmer Rouge had a policy of [[state atheism]].<ref name="Wessinger2000">{{cite book|last=Wessinger|first=Catherine|title=Millennialism, Persecution, and Violence: Historical Cases|year=2000|publisher=[[Syracuse University Press]]|isbn=978-0815628095|page=282|quote=Democratic Kampuchea was officially an atheist state, and the persecution of religion by the Khmer Rouge was matched in severity only by the persecution of religion in the communist states of Albania and North Korea, so there were not any direct historical continuities of Buddhism into the Democratic Kampuchea era.}}</ref> Buddhist monks were viewed as social parasites and designated a "special class". Within a year of the Khmer Rouge's victory in the civil war, the country's monks were set to manual labor in the rural co-operatives and irrigation projects.{{sfn|Short|2004|p=326}}
Despite its ideological iconoclasm, many historical monuments were left undamaged by the Khmer Rouge;{{sfn|Short|2004|p=313}} for Pol Pot's government, like its predecessors, the historic state of [[Angkor]] was a key point of reference.{{sfn|Short|2004|p=293}}

Several isolated revolts broke out against Pol Pot's government. The Khmer Rouge Western Zone regional chief Koh Kong and his followers began launching small-scale attacks on government targets along the Thai border.{{sfn|Short|2004|p=354}} There were also several village rebellions among the Cham.{{sfn|Short|2004|p=354}} In February 1976, explosions in [[Siem Reap]] destroyed a munitions depot. Pol Pot suspected senior military figures were behind the bombing and, although unable to prove who was responsible, had several army officers arrested.{{sfn|Short|2004|pp=354–55}}

In September 1976, various party members were arrested and accused of conspiring with Vietnam to overthrow Pol Pot's government.{{sfn|Short|2004|p=359}} Over the coming months the numbers arrested grew. The government invented claims of assassination attempts against its leading members to justify this internal crack-down within the CPK itself.{{sfn|Short|2004|p=360}} These party members were accused of being spies for either the CIA, the Soviet [[KGB]], or the Vietnamese.{{sfnm|1a1=Chandler|1y=1992|1p=134|2a1=Short|2y=2004|2p=367}} They were encouraged to confess to the accusations, often after torture or the threat of torture, with these confessions then being read out at party meetings.{{sfn|Short|2004|pp=344, 366}} As well as occurring in the area around Phnom Penh, trusted party cadres were sent into the country's zones to initiate further purges among the party membership there.{{sfn|Short|2004|pp=368–70}}

The Khmer Rouge converted a disused secondary school in Phnom Penh's [[Tuol Sleng]] region into a security prison, [[Tuol Sleng Genocide Museum|S-21]]. It was placed under the responsibility of the defence minister, [[Son Sen]].{{sfnm|1a1=Chandler|1y=1992|1pp=130, 133|2a1=Short|2y=2004|2p=358}} The numbers sent to S-21 grew steadily as the CPK purge proceeded. In the first half of 1976, about 400 people were sent there; in the second half of the year that number was nearer to 1,000. By the spring of 1977, 1,000 people were being sent there each month.{{sfn|Short|2004|p=364}} Between 15,000 and 20,000 people would be killed at S-21 during the Khmer Rouge period.{{sfn|Short|2004|p=364}} About a dozen of them were Westerners.{{sfn|Short|2004|p=367}} Pol Pot never personally visited S-21.{{sfn|Short|2004|p=371}}

From late 1976 onward, and especially in the middle of 1977, the levels of violence increased across Democratic Kampuchea, particularly at the village level.{{sfn|Short|2004|p=370}} In rural areas, most of the killings were perpetrated by young cadres who were enforcing what they believed to be the government's will.{{sfn|Chandler|1992|p=168}} Across the country, peasant cadres tortured and killed members of their communities whom they disliked. Many cadres ate the livers of their victims and tore unborn foetuses from their mothers for use as kun krak talismans.{{sfn|Short|2004|p=371}} The CPK Central Command was aware of such practices but did nothing to stop them.{{sfn|Short|2004|p=371}} By 1977, the growing violence, coupled with poor food, was generating disillusionment even within the Khmer Rouge's core support base.{{sfn|Short|2004|p=371}} Growing numbers of Cambodians attempted to flee into Thailand and Vietnam.{{sfn|Short|2004|p=372}} In the autumn of 1977, Pol Pot declared the purges at an end.{{sfn|Short|2004|p=368}} According to the CPK's own figures, by August 1977 between 4,000 and 5,000 party members had been liquidated as "enemy agents" or "bad elements".{{sfn|Short|2004|p=368}}

In 1978, the government initiated a second purge, during which tens of thousands of Cambodians were accused of being Vietnamese sympathisers and killed.{{sfn|Short|2004|p=383}} At this point the remaining CPK members who had spent time in Hanoi were killed, along with their children.{{sfn|Short|2004|pp=384–85}} In January 1978, Pol Pot announced to his colleagues that their slogan should be "Purify the Party! Purify the army! Purify the cadres!"{{sfn|Short|2004|p=384}}
