The Khmer Rouge was the extremist Communist organization that ruled Cambodia from 1975 to 1979. It was one of the most lethal regimes of the 20th c and was responsible for the deaths of an estimated 1.7 million people through execution, starvation, and forced labor. Victims were often buried in mass grave sites, known as The Killing Fields, scattered throughout Cambodia. Whom did the Khmer Rouge target for their “re-education” campaigns?
