Which group was the victim in the Cambodian genocide?

The primary victims of the Cambodian genocide, which occurred from 1975 to 1979 under the Khmer Rouge regime, were ethnic Cambodians, particularly those perceived as intellectuals, professionals, and members of the educated classes. Additionally, minority groups such as the Cham Muslims and ethnic Vietnamese were targeted. The regime's brutal policies led to the deaths of an estimated 1.7 million people through executions, forced labor, and starvation.
