Introduction
From 1975 to 1979, Cambodia was ruled by one of the most brutal and murderous regimes in modern history: the Khmer Rouge. Led by the Marxist revolutionary Pol Pot, the Khmer Rouge seized power after a devastating civil war and embarked on a radical transformation of Cambodian society that resulted in the deaths of up to two million people, or one quarter of the country‘s population.[^1] The Khmer Rouge era remains one of the darkest chapters in the history of Southeast Asia, and its legacy continues to haunt Cambodia to this day.
Historical Background
To understand the rise of the Khmer Rouge, it is necessary to situate it within the broader context of Cambodian history. Cambodia gained independence from France in 1953, but the country remained politically unstable in the decades that followed. In the 1960s, Cambodia was drawn into the Vietnam War, as the North Vietnamese Army and the Viet Cong used Cambodian territory as a base for operations against South Vietnam and the United States.[^2]
In 1969, the United States began a massive bombing campaign in Cambodia, aimed at destroying North Vietnamese supply lines and bases. Over the next four years, the U.S. dropped more than 2.7 million tons of bombs on Cambodia, more than the total dropped on Japan during World War II.^3 The bombing campaign devastated rural Cambodia and drove many peasants to join the Khmer Rouge insurgency.
In 1970, the Cambodian military, led by General Lon Nol, staged a coup against Prince Norodom Sihanouk, who had ruled the country since independence. The coup plunged Cambodia into civil war, with the Khmer Rouge and Sihanouk‘s supporters on one side and Lon Nol‘s U.S.-backed government on the other. Over the next five years, the Khmer Rouge gradually gained control of the Cambodian countryside, aided by the chaos and destruction wrought by the war.[^4]
The Rise of the Khmer Rouge
The Khmer Rouge was a communist movement that emerged in the 1960s, inspired by the success of the Chinese Revolution and the writings of Mao Zedong. Many of its leaders, including Pol Pot, had studied in France and became radicalized there. They saw Cambodia as a feudal, backward society that needed to be completely transformed through revolutionary violence.[^5]
In April 1975, Khmer Rouge forces entered the capital city of Phnom Penh and declared victory. They immediately set about implementing their radical vision of a communist utopia. The first step was to evacuate all cities and towns, forcing the entire urban population into the countryside to work in collective farms and labor camps. The Khmer Rouge abolished money, private property, and traditional culture, and set out to create a classless, agrarian society.[^6]
The Killing Fields
The Khmer Rouge‘s rule was marked by unimaginable brutality and suffering. The regime saw enemies everywhere, and set out to purge the country of anyone perceived as a threat to the revolution. This included intellectuals, former government officials, ethnic minorities such as the Cham Muslims and ethnic Vietnamese, and even those within the Khmer Rouge‘s own ranks who were suspected of disloyalty.[^7]
The most notorious site of the Khmer Rouge‘s brutality was the Tuol Sleng prison in Phnom Penh, also known as S-21. An estimated 14,000 people were tortured and killed at Tuol Sleng, including men, women, and children. Prisoners were subjected to brutal interrogations, forced confessions, and sadistic torture methods such as waterboarding, electric shocks, and pulling out fingernails. Only a handful of prisoners survived Tuol Sleng; the rest were executed and buried in mass graves on the outskirts of the city, in what became known as the Killing Fields.[^8]
The scale of the killing was staggering. At the Choeung Ek killing field alone, an estimated 17,000 people were executed and buried in mass graves.[^9] Across the country, the death toll reached over a million people, or roughly one in four Cambodians. Some estimates put the total number of deaths as high as 2.2 million.[^10]
| Killing Field Site | Estimated Number of Victims |
|---|---|
| Choeung Ek | 17,000 |
| Tuol Sleng (S-21) | 14,000 |
| Kampong Chhnang | 14,000 |
| Kampong Cham | 10,000 |
| Kratie | 10,000 |

The Fall of the Khmer Rouge
The nightmare of Khmer Rouge rule finally ended in January 1979, when Vietnamese forces invaded Cambodia and drove Pol Pot‘s army into the jungle. The Vietnamese installed a new government led by former Khmer Rouge cadres who had defected to Vietnam, and began the long process of rebuilding the shattered country.[^12]
The Khmer Rouge, however, was not completely defeated. They continued to fight a guerrilla war from bases along the Thai border for another two decades, supported by China and the United States as a bulwark against Vietnamese influence in the region. It was not until the late 1990s that the Khmer Rouge finally collapsed, after a series of defections and arrests of its top leaders.[^13]
The Aftermath and Legacy
In the years since the fall of the Khmer Rouge, Cambodia has struggled to come to terms with the legacy of the genocide. The Extraordinary Chambers in the Courts of Cambodia (ECCC), a UN-backed tribunal, was established in 2006 to try senior Khmer Rouge leaders for crimes against humanity and genocide. To date, only three people have been convicted: Kaing Guek Eav (alias Duch), the head of Tuol Sleng prison; Nuon Chea, the chief ideologue of the Khmer Rouge; and Khieu Samphan, the former head of state. Pol Pot himself died in 1998 without ever facing justice.[^14]
The trauma of the Khmer Rouge era continues to haunt Cambodia today. Many survivors still suffer from post-traumatic stress disorder, and the country‘s infrastructure and institutions remain weakened by the years of destruction and neglect. Cambodia remains one of the poorest countries in Southeast Asia, with a per capita GDP of just $1,643 in 2020.[^15]
Yet there are also signs of hope and resilience. Cambodia has made significant strides in economic development and poverty reduction in recent years, and the country‘s vibrant cultural scene is a testament to the enduring spirit of the Cambodian people. Efforts to document and memorialIze the genocide, such as the Tuol Sleng Genocide Museum and the Choeung Ek Memorial, ensure that the victims of the Khmer Rouge will not be forgotten.[^16]
Conclusion
The Khmer Rouge regime was one of the most brutal and murderous in modern history, responsible for the deaths of up to two million people in just four years. Its legacy continues to shape Cambodia today, even as the country strives to move forward and rebuild.
The story of the Khmer Rouge is a tragic reminder of the depths of human cruelty and the dangers of totalitarian ideologies. It is a warning to the world of what can happen when a regime is allowed to operate with impunity, and when the international community fails to intervene.
Yet it is also a story of survival, resilience, and the unbreakable spirit of the Cambodian people. As we remember the victims of the Khmer Rouge and work to prevent future atrocities, we must also honor the courage and determination of those who lived through one of the darkest chapters in human history.
