# Khmer Rouge Establishes Kampuchea

> The Khmer Rouge takeover initiated one of the 20th century's most devastating genocides, killing approximately two million Cambodians in a failed agrarian utopia.

On April 17, 1975, the Khmer Rouge, a communist faction led by Pol Pot, seized control of Cambodia's capital Phnom Penh and established Democratic Kampuchea. Over the next four years, the regime's radical agrarian ideology and brutal enforcement would result in the deaths of approximately 1.7 to 2 million people—roughly a quarter of Cambodia's population.

## Summary

Khmer Rouge is the name that was popularly given to members of the Communist Party of Kampuchea (CPK), and by extension to Democratic Kampuchea, which ruled Cambodia between 1975 and 1979. The name was coined in the 1960s by Norodom Sihanouk to describe his country's heterogeneous, communist-led dissidents, with whom he allied after the 1970 Cambodian coup d'état.
