In 1975, a communist regime known as the Khmer Rouge conquered the Cambodian capital of Phnom Penh. The occupation set in motion a four-year campaign of genocide that would wipe out 2 million people – a quarter of the country’s population. Developed through a partnership between USC Shoah Foundation and the Documentation Center of Cambodia, the Cambodian Genocide Collection offers testimonies of survivors who escaped the killings from 1975 to 1979.
