The Cambodian genocide^[a] was the systematic persecution and killing of Cambodian citizens^[b] by the Khmer Rouge under the leadership of Prime Minister of Democratic Kampuchea, Pol Pot. It resulted in the deaths of 1.5 to 2 million people from 1975 to 1979, nearly 25% of Cambodia's population in 1975 (c. 7.8 million).^[3][4]

Pol Pot and the Khmer Rouge were supported for many years by the Chinese Communist Party (CCP) and its chairman, Mao Zedong;^[c] it is estimated that at least 90% of the foreign aid which the Khmer Rouge received came from China, including at least US$1 billion in interest-free economic and military aid in 1975 alone.^[10][11][12] After it seized power in April 1975, the Khmer Rouge wanted to turn the country into an agrarian socialist republic, founded on the policies of ultra-Maoism and influenced by the Cultural Revolution.^[d] Pol Pot and other Khmer Rouge officials met with Mao in Beijing in June 1975, receiving approval and advice, while high-ranking CCP officials such as Politburo Standing Committee member Zhang Chunqiao later visited Cambodia to offer help.^[e] To fulfill its goals, the Khmer Rouge emptied the cities and frogmarched Cambodians to labor camps in the countryside, where mass executions, forced labor, physical abuse, torture, malnutrition, and disease were rampant.^[17][18] In 1976, the Khmer Rouge renamed the country Democratic Kampuchea.

The massacres ended when the Vietnamese military invaded in 1978 and toppled the Khmer Rouge regime.^[19] By January 1979, 1.5 to 2 million people had died due to the Khmer Rouge's policies, including 200,000–300,000 Chinese Cambodians, 90,000–500,000^[f] Cambodian Cham (who are mostly Muslim),^[23][24][25] and 20,000 Vietnamese Cambodians.^[26][27] 20,000 people passed through the Security Prison 21, one of the 196 prisons the Khmer Rouge operated,^[4][28] and only seven adults survived.^[29] The prisoners were taken to the Killing Fields, where they were executed (often with pickaxes, to save bullets)^[30] and buried in mass graves. Abduction and indoctrination of children was widespread, and many were persuaded or forced to commit atrocities.^[31] As of 2009, the Documentation Center of Cambodia has mapped 23,745 mass graves containing approximately 1.3 million suspected victims of execution. Direct execution is believed to account for up to 60% of the genocide's death toll,^[32] with other victims succumbing to starvation, exhaustion, or disease.

The genocide triggered a second outflow of refugees, many of whom escaped to neighboring Thailand and, to a lesser extent, Vietnam.^[33] In 2003, by agreement^[34] between the Cambodian government and the United Nations, the Extraordinary Chambers in the Court of Cambodia (Khmer Rouge Tribunal) were established to try the members of the Khmer Rouge leadership responsible for the Cambodian genocide. Trials began in 2009.^[35] On 26 July 2010, the Trial Chamber convicted Kang Kek Iew for crimes against humanity and grave breaches of the 1949 Geneva Conventions. The Supreme Court Chamber increased his sentence to life imprisonment. Nuon Chea and Khieu Samphan were tried and convicted in 2014 of crimes against humanity and grave breaches of the Geneva Conventions. On 28 March 2019, the Trial Chamber found Nuon Chea and Khieu Samphan guilty of crimes against humanity, grave breaches of the Geneva Conventions, and genocide of the Vietnamese ethnic, national and racial group. The Chamber additionally convicted Nuon Chea of genocide of the Cham ethnic and religious group under the doctrine of superior responsibility.^[2] Both Nuon Chea and Khieu Samphan were sentenced to terms of life imprisonment.^[36]
