The Cambodian genocide (Khmer: របបប្រល័យពូជសាសន៍) was carried out by the Khmer Rouge regime under the leadership of Pol Pot, killing approximately 1.5 to 3 million Cambodian people from 1975 to 1979. The Khmer Rouge wanted to turn the country into a socialist agrarian republic, founded on the policies of Maoism. In 1976, the Khmer Rouge changed the name of the country to Democratic Kampuchea. In order to fulfill their goals, the Khmer Rouge emptied the cities and forced Cambodians to relocate to labor camps in the countryside, where mass executions, forced labor, physical abuse, malnutrition, and disease were prevalent. This resulted in the death of approximately 25 percent of Cambodia's total population. Approximately 20,000 people passed through the Tuol Sleng Centre (also known as Security Prison S-21), one of the 196 prisons operated by the Khmer Rouge, and only 7 adults survived. The opposition were taken to the Killing Fields, where they were executed (often with pickaxes to save bullets) and buried in mass graves. The abduction and indoctrination of children was widespread, and many were persuaded or forced to commit atrocities. The Vietnamese invasion of Cambodia ended the genocide by defeating the Khmer Rouge in 1979.

On 2 January 2001, the Cambodian government established the Khmer Rouge Tribunal, to try the members of the Khmer Rouge leadership responsible for the Cambodian genocide. Trials began on 17 February 2009. On 7 August 2014, Nuon Chea and Khieu Samphan were convicted and received life sentences for crimes against humanity during the genocide. As of 2009, the Cambodian NGO Documentation Center of Cambodia has mapped some 23,745 mass graves containing approximately 1.3 million suspected victims of execution. Direct execution is believed to account for roughly 60% of the full death toll during the genocide, with other victims succumbing to starvation or disease.
The Khmer Rouge regime frequently arrested and often executed anyone suspected of connections with the former Cambodian government or foreign governments, as well as professionals, intellectuals, the Buddhist monkhood, and ethnic minorities. As a result, Pol Pot has been described by journalists and historians, William Branigin for example, as "a genocidal tyrant". British sociologist Martin Shaw described the Cambodian genocide as "the purest genocide of the Cold War era". The attempt to purify Cambodian society along racial, social and political lines led to purges of the Cambodia's previous military and political leadership, along with business leaders, journalists, students, doctors, and lawyers.
Ethnic Vietnamese, ethnic Thai, ethnic Chinese, ethnic Cham, Cambodian Christians, and other minorities were also targeted. The Khmer Rouge forcibly relocated minority groups and banned the use of minority languages. By decree, the Khmer Rouge banned the existence of more than 20 minority groups, which constituted 15% of the country's population.
Ethnic and religious victimsEdit
The Khmer Rouge initially ordered the expulsion of ethnic Vietnamese from Cambodia but then massacred large numbers of that population as they attempted to flee the country. The regime then prevented the remaining 20,000 ethnic Vietnamese from fleeing, and much of this group was also executed. The Khmer Rouge also used the media to support their goals of genocide. Radio Phnom Penh called on Cambodians to "exterminate the 50 million Vietnamese."
Additionally, the Khmer Rouge conducted many cross-border raids into Vietnam where they slaughtered an estimated 30,000 Vietnamese civilians. Most notably, during the Ba Chúc massacre in April 1978, the Khmer Rouge military crossed the border and entered the village, slaughtering 3,157 Vietnamese civilians at once. This forced an urgent response from the Vietnamese government, precipitating the Cambodian–Vietnamese War in which the Khmer Rouge was ultimately defeated.
The state of the Chinese Cambodians during the Khmer Rouge regime has been described as "the worst disaster ever to befall any ethnic Chinese community in Southeast Asia." Cambodians of Chinese descent were massacred by the Khmer Rouge under the justification that they "used to exploit the Cambodian people". The Chinese were stereotyped as traders and moneylenders associated with capitalism, while historically the group had attracted resentment due to their lighter skin color and cultural differences. Hundreds of Chinese families were rounded up in 1978 and told that they were to be resettled, but were actually executed. At the beginning of the Khmer Rouge regime in 1975, there were 425,000 ethnic Chinese in Cambodia; by the end of 1979 there were just 200,000. Furthermore, the Chinese were predominantly city-dwellers, making them vulnerable to the Khmer Rouge's revolutionary ruralism and evacuation of city residents to farms. The government of the People's Republic of China did not protest the killings of ethnic Chinese in Cambodia.
According to Ben Kiernan, the "fiercest extermination campaign was directed against the ethnic Cham Muslim minority." Islam was seen as an "alien" and "foreign" culture that did not belong in the new Communist system. Initially, the Khmer Rouge aimed for the "forced assimilation" of Chams through population dispersal. Pol Pot then began using intimidation efforts against the Chams that included the assassination of village elders but ultimately ordered the full-scale mass killing of Cham people. American professor Samuel Totten and Australian professor Paul R. Bartrop estimate that these efforts would have completely wiped out the Cham population were it not for the overthrow of the Khmer Rouge in 1979.
Under the leadership of Pol Pot, who was an ardent atheist, the Khmer Rouge had a policy of state atheism. According to Catherine Wessinger, "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."  All religions were banned, and the repression of adherents of Islam, Christianity, and Buddhism was extensive. It is estimated that up to 50,000 Buddhist monks were massacred by the Khmer Rouge.
Ideology played an important role in the genocide. Pol Pot and the Khmer Rouge aimed to bring Cambodia back to its "mythic past" of the powerful Khmer Empire, to stop corrupting influences like foreign aid and western culture, and to restore the country to an agrarian society. Attempts to implement these goals were key factors in the ensuing genocide. One Khmer Rouge leader said that the killings were meant for the "purification of the populace."
The Khmer Rouge forced virtually the entire population of Cambodia into mobile work teams. Michael Hunt said that it was "an experiment in social mobilization unmatched in twentieth-century revolutions." The Khmer Rouge used an inhumane forced labor regime, starvation, forced resettlement, land collectivization, and state terror to keep the population in line.
Historian Ben Kiernan has compared the Cambodian genocide to the Armenian Genocide perpetrated by the Ottoman Empire and the Holocaust perpetrated by Nazi-era Germany. While each was unique, they shared certain common features. Racism was a major part of the ideology of all three of the genocidal regimes. All three targeted religious minorities and tried to use force of arms to expand into what they believed to be their historical heartlands (the Khmer Empire, Turkestan, and Lebensraum respectively), while all three regimes "idealized their ethnic peasantry as the true 'national' class, the ethnic soil from which the new state grew."
Torture and medical experimentsEdit
The Khmer Rouge regime is also well known for having practiced tortures and medical experiments. There are many accounts of torture in the S-21 records and in the documents of the trial. Tortures weren't only meant to force the prisoner to confess, they were just used for fun among the prison guards. They feared that they would become themselves prisoners of the same prison if they treated the prisoners well. Moreover, unlike other totalitarian regimes (such as Nazism) where soldiers and guards were adults and normally suffered from psychological stress when they had to carry out mass killings with rifles (which was one of the reasons that led to the adoption of gas chambers), prison guards of the Khmer Rouge regime were just youths and most of them couldn't even realize in full what they were doing.
The previous doctors were killed or sent to the countryside to work as farmers during the Khmer Rouge and the library of the Medical Faculty in Phnom Penh was set on fire. The regime then employed child medics, who were just teenagers with no or very little training in that job. They didn't have any knowledge of Western medicine (which had been forbidden since it was considered a capitalist invention), and they had to practice their own medical experiments and make progress by themselves. They didn't have Western medicines (since Cambodia, according to the Khmer Rouge, had to be self-sufficient) and all the medical experiments were systematically conducted without anesthetics. 
A medic who worked inside S-21 told that a a 17-year-old girl had her throat slit and her abdomen pierced before being beaten and put into water for the whole night. This procedure was repeated many times and it was carried out without anesthetics.
In a hospital of Kampong Cham province, child medics cut off the intestine of a living non-consenting person and they joined their ends in order to study the healing process. The patient died after three days due to the "operation".
In the same hospital, other "physicians" trained by the Khmer Rouge opened the chest of a living person, just to see the heart beating. The operation resulted in the immediate death of the patient.
Other testimonies, as well as the policy itself implemented by the Khmer Rouge, suggest that those weren't just isolated cases. They also performed drug testing, for instance by injecting coconut juice into a living person's body and studying the effects. Coconut juice-injection was often lethal.
The book Cambodge année zéro ("Cambodia Year Zero") by François Ponchaud was released in 1977 and translated into English in 1978. Ponchaud was one of the first authors to bring the Cambodian genocide to the world's attention. Ponchaud has said that the genocide "was above all, the translation into action the particular vision of a man [sic]: A person who has been spoiled by a corrupt regime cannot be reformed, he must be physically eliminated from the brotherhood of the pure." Murder of a Gentle Land: The Untold Story of a Communist Genocide in Cambodia by John Barron and Anthony Paul was published in 1977. The book drew on accounts from refugees, and an abridged version published in Reader's Digest was widely read.
In 1973, Kenneth M. Quinn of the United States embassy raised concerns over the atrocities being carried out by the Khmer Rouge during the Cambodian Civil War. In a report, he stated that the Khmer Rouge had "much in common with those of totalitarian regimes in Nazi Germany and the Soviet Union."  Quinn has written of the Khmer Rouge: "[w]hat emerges as the explanation for the terror and violence that swept Cambodia during the 1970s is that a small group of alienated intellectuals, enraged by their perception of a totally corrupt society and imbued with a Maoist plan to create a pure socialist order in the shortest possible time, recruited extremely young, poor, and envious cadres, instructed them in harsh and brutal methods learned from Stalinist mentors, and used them to destroy physically the cultural underpinnings of the Khmer civilization and to impose a new society through purges, executions, and violence."
During the genocide, China was the main international patron of the Khmer Rouge, supplying "more than 15,000 military advisers"[attribution needed] and most of its external aid. As a result of Chinese and Western opposition to the Vietnamese invasion of 1978-79, the Khmer Rouge continued to hold Cambodia's United Nations seat until 1982, after which the seat was filled by a Khmer Rouge-dominated coalition known as the Coalition Government of Democratic Kampuchea. Motivated by its opposition to Vietnam, China trained Khmer Rouge soldiers on its soil from 1979 to at least 1986, "stationed military advisers with Khmer Rouge troops as late as 1990," and "supplied at least $1 billion in military aid" during the 1980s. After the 1991 Paris Peace Accords, Thailand continued to allow the Khmer Rouge "to trade and move across the Thai border to sustain their activities... although international criticism, particularly from the United States and Australia... caused it to disavow passing any direct military support." There are also allegations that the United States directly or indirectly supported the Khmer Rouge to weaken Vietnam's influence in Southeast Asia.
Use of childrenEdit
The Khmer Rouge exploited thousands of desensitized, conscripted children in their early teens to commit mass murder and other atrocities during and after the genocide. The indoctrinated children were taught to follow any order without hesitation. The organisation continued to use children extensively until at least 1998, often forcibly recruiting them. During this period, the children were deployed mainly in unpaid support roles, such as ammunition-carriers, and also as combatants. Many children had fled the Khmer Rouge without a means to feed themselves, and believed that joining the government forces would enable them to survive, although local commanders frequently denied them any pay.
War crimes trialsEdit
On 15 July 1979, following the overthrow of the Khmer Rouge, the new government of Cambodia passed "Decree Law No. 1." This allowed for the trial of Pol Pot and Ieng Sary for the crime of genocide. They were given an American defense lawyer, Hope Stevens., and were tried in absentia and convicted of genocide. In January 2001, the Cambodian National Assembly passed legislation to form a tribunal to try additional members of the Khmer Rouge regime.
In 1999, Kang Kek Iew ("Comrade Duch") was interviewed by Nic Dunlop and Nate Thayer and admitted his guilt for crimes carried out in Tuol Sleng prison, where up to 17,000 political prisoners were executed. He expressed sorrow for his actions, stating that he was willing to stand trial and give evidence against his former comrades. During his trial in February and March 2009, Duch admitted that he was responsible for the crimes carried out at Tuol Sleng. On 26 July 2010, he was found guilty on charges of crimes against humanity, torture, and murder and was sentenced to 35 years in prison. On 3 February 2012 his previous sentence was replaced with life imprisonment.
Nuon Chea ("Brother Number Two") was arrested on 19 September 2007. At the end of his 2013 trial he denied all charges, stating that he had not given orders "to mistreat or kill people to deprive them of food or commit any genocide." He was convicted in 2014 and sentenced to life imprisonment. He has expressed remorse and accepted moral responsibility for his crimes, stating "I would like to sincerely apologize to the public, the victims, the families, and all Cambodian people."
After being located in an opulent Phnom Penh villa, Ieng Sary was arrested on 12 November 2007 and indicted for crimes against humanity, as was his wife Ieng Thirith, who had been an unofficial adviser to the regime. On 17 November 2011, following evaluations from medical experts, Thirith was found to be unfit to stand trial due to a mental condition. Sary died of heart failure in 2013 while his trial was in progress.
Another senior Khmer Rouge leader, Khieu Samphan, was arrested on 19 November 2007 and charged with crimes against humanity. He was convicted in 2014 and sentenced to life imprisonment. At a hearing on 23 June 2017, Samphan stated a desire to bow to the memory of his guiltless victims, while also claiming that he suffered for those who fought for their ideal to have a brighter future.
A few months before his death on 15 April 1998, Pol Pot was interviewed by Nate Thayer. During the interview, he stated that he had a clear conscience and denied being responsible for the genocide. Pol Pot asserted that he "came to carry out the struggle, not to kill people." According to Alex Alvarez, Pol Pot "portrayed himself as a misunderstood and unfairly vilified figure". In 2013, Cambodian Prime Minister Hun Sen passed legislation that prohibits the denial of the Cambodian genocide and other war crimes committed by the Khmer Rouge. The legislation was passed despite comments by opposition leader Kem Sokha, who is the deputy president of the Cambodian National Rescue Party. Sokha stated that exhibits at the Tuol Sleng Genocide Museum were fabricated and that the artifacts had been faked by the Vietnamese following their invasion in 1979. Sokha's party has claimed that his comments were taken out of context.
In literature and mediaEdit
Filmmaker Rithy Panh, a survivor of the genocide, is "considered by many to be the cinematic voice of Cambodia." Panh has directed several documentaries on the genocide, including S-21: The Khmer Rouge Killing Machine, which has been noted by critics for "allow[ing] us to observe how memory and time may collapse to render the past as present and by doing so reveal the ordinary face of evil." The genocide is portrayed in the 1984 Academy Award-winning film The Killing Fields and in Patricia McCormick's 2012 novel Never Fall Down.
The genocide is also recounted by Loung Ung in her memoir First They Killed My Father (2000). The book was adapted into a 2017 biographical film directed by Angelina Jolie. Set in 1975, the film depicts 5-year-old Ung who is forced to be trained as a child soldier while her siblings are sent to labor camps by the Khmer Rouge regime.

Since 1979, the so-called Pol Pot regime has been equated to Hitler and the Nazis. This is why the word 'genocide' (associated with Nazism) has been used for the first time in a distinctly Communist regime by the invading Vietnamese to distance themselves from a government they had overturned. This 'revisionism' was expressed in several ways. The Khmer Rouge were said to have killed 3.3 million, some 1.3 million more people than they had in fact killed. There was one abominable state prison, S–21, now the Tuol Sleng Genocide Museum. In fact, there were more than 150 on the same model, at least one per district.
