Question: The Cambodian Genocide was carried out by the followers of what group?
Context: Cambodian Rocks is a compilation of 22 uncredited, untitled Cambodian psychedelic and garage rock songs from the late 1960s and early 1970s.  When the tracks were recorded, musicians in the thriving music scene were combining Western rock and pop genres with their own styles and techniques.  When the Khmer Rouge came to power in 1975, artists were among those viewed as a threat to the regime's agrarian socialist vision, and several of the performers on the album are believed to have been among those killed during the ensuing Cambodian Genocide of 1975-1979.  Little information about them or their creative output has survived. Youk Chhang is the Executive Director of the Documentation Center of Cambodia (DC-Cam) and a survivor of the Khmer Rouge’s “killing fields.”  He became DC-Cam’s leader in 1995, when the Center was founded as a field office of Yale University’s Cambodian Genocide Program to conduct research, training and documentation relating to the Khmer Rouge regime.  Chhang continued to run the Center after its inception as an independent Cambodian non-governmental organization in 1997 and is currently building on DC-Cam’s work to establish the Sleuk Rith Institute, a permanent hub for genocide studies in Asia, based in Phnom Penh. The Cambodian genocide (Khmer: របបប្រល័យពូជសាសន៍ ) was carried out by the Khmer Rouge (KR) regime led by Pol Pot between 1975 and 1979 in which an estimated 1.5 to 3 million people died.  The Cambodian Civil War resulted in the establishment of Democratic Kampuchea by the Khmer Rouge, who had planned to create a form of agrarian socialism founded on the ideals of Stalinism and Maoism.  The subsequent policies caused forced relocation of the population from urban centers, torture, mass executions, use of forced labor, malnutrition, and disease which led to the deaths of an estimated 25 percent of the total population (around 2 million people).  The genocide ended in 1979 following the Vietnamese invasion of Cambodia.  As of 2009, 23,745 mass graves have been discovered. Gregory H. Stanton is the Research Professor in Genocide Studies and Prevention at the George Mason University in Fairfax County, Virginia, United States.  He is best known for his work in the area of genocide studies.  He is the founder (1999) and president of "Genocide Watch", the founder (1981) and director of the "Cambodian Genocide Project", and the founder (1999) and Chair of the "International Campaign to End Genocide".  From 2007 to 2009 he was the President of the International Association of Genocide Scholars. Stuart Robert Glass was a Canadian adventurer and yachtsman killed by the Khmer Rouge in August 1978 while sailing a little yacht named "Foxy Lady" through Cambodian waters.  One of nine "Western" yachtsmen known to have been seized by the Democratic Kampuchean regime, between April and November 1978.  He was the sole Canadian victim of the 1975–79 Cambodian genocide. Cambodian genocide denial was the belief expressed by many Western academics that claims of atrocities by the Khmer Rouge government (1975-1979) in Cambodia were much exaggerated.  Many scholars of Cambodia and intellectuals, opposed to the U.S. involvement in the Vietnam War, denied or minimized the human rights abuses of the Khmer Rouge, characterizing contrary information as "tales told by refugees" and U.S. propaganda.  They viewed the assumption of power by the communist Khmer Rouge as a positive development for the people of Cambodia who had been severely impacted by the Vietnam War and the Cambodian Civil War. The Cambodian Killing Fields (Khmer: វាលពិឃាត , ] ) are a number of sites in Cambodia where collectively more than a million people were killed and buried by the Communist Khmer Rouge regime, during its rule of the country from 1975 to 1979, immediately after the end of the Cambodian Civil War (1970–1975).  The mass killings are widely regarded as part of a broad state-sponsored genocide (the Cambodian genocide). The Khmer Rouge ( , ] , "Red Khmers"; Khmer: ខ្មែរក្រហម "Khmer Kror-Horm") was the name given to the followers of the Communist Party of Kampuchea in Cambodia.  It was formed in 1968 as an offshoot of the Vietnam People's Army from North Vietnam, and allied with North Vietnam, the Viet Cong, and the Pathet Lao during the Vietnam War against the anti-communist forces from 1968 to 1975.  The Khmer Rouge emerged victorious in the Cambodian Civil War, overthrew the military dictatorship of the Khmer Republic and installed their own government Democratic Kampuchea in 1975, led by Pol Pot, Nuon Chea, Ieng Sary, Son Sen, and Khieu Samphan.  This was followed by the Cambodian genocide which occurred from 1975 until 1979, when the Khmer Rouge was finally removed from power by Vietnam in the Cambodian–Vietnamese War.  The military power of the Khmer Rouge organization was not broken however, and a long era of guerrilla warfare involving large swaths of the Cambodian countryside began.  Many different military factions were involved in the guerrilla war era and it ended around 1994. The Extraordinary Chambers in the Courts of Cambodia (ECCC), commonly known as the Cambodia Tribunal or Khmer Rouge Tribunal, is a court established to try the most senior responsible members of the Khmer Rouge for alleged violations of international law and serious crimes perpetrated during the Cambodian genocide.  Although it is a national court, it was established as part of an agreement between the Royal Government of Cambodia and the United Nations, and its members include both local and foreign judges.  It is considered a hybrid court; as the ECCC was created by the government in conjunction with the UN, but remains independent of them, with trials held in Cambodia using Cambodian and international staff.  The Cambodian court invites international participation in order to apply international standards. Eliticide or elitocide refers to "the killing of the leadership, the educated, and the clergy of a group."  It is usually carried out during the beginning of a genocide and done to cripple a possible resistance against perpetrators.  Examples include the Armenian genocide, Cambodian genocide, German-Soviet occupation of Poland, and instances in the Yugoslav Wars.  The term was first used in 1992 by British reporter Michael Nicholson to describe the Bijeljina massacre in Bosnia and Herzegovina.  During the Bosnian War local Serbs would point out prominent Bosniaks to be killed afterwards by Serb soldiers.
