Cambodian Genocide Timeline

The Cambodian Genocide, which occurred from 1975 to 1979, was a brutal and devastating period in the history of Cambodia. During this time, the Khmer Rouge, led by Pol Pot, implemented radical social and agricultural reforms that resulted in the deaths of an estimated 1.7 to 2.2 million people, out of a population of approximately 8 million, through executions, forced labor, and starvation. The genocide was characterized by the forced relocation of people from urban areas to rural agricultural collectives, the abolition of money, markets, and private property, and the execution of intellectuals, members of the middle class, and those deemed enemies of the state.
Early History of the Khmer Rouge

The Khmer Rouge, which translates to “Red Khmer,” was a communist organization that emerged in the 1960s. The group was led by Pol Pot, who had been influenced by the teachings of Mao Zedong and the Chinese Communist Party. The Khmer Rouge’s ideology was based on the concept of agrarian socialism, which emphasized the importance of agricultural production and the need to create a self-sufficient economy. In the early 1970s, the Khmer Rouge began to gain support from the Cambodian people, who were dissatisfied with the government of Lon Nol and the ongoing Vietnam War.
Rise to Power
In 1975, the Khmer Rouge launched a successful attack on Phnom Penh, the capital city of Cambodia, and seized control of the government. Pol Pot and his associates quickly implemented their radical policies, which included the forced relocation of people from urban areas to rural agricultural collectives. The Khmer Rouge also abolished money, markets, and private property, and executed anyone deemed to be an enemy of the state, including intellectuals, members of the middle class, and those who wore glasses or had other signs of being educated.

Key Events of the Genocide

During the period of the Khmer Rouge’s rule, several key events occurred that contributed to the genocide. One of the most significant events was the forced relocation of people from urban areas to rural agricultural collectives. This policy, known as the “evacuation of the cities,” was designed to create a self-sufficient agrarian economy, but it ultimately led to the deaths of hundreds of thousands of people who were forced to work in difficult conditions with little food or shelter.
Mass Executions
Another key event of the genocide was the mass executions of intellectuals, members of the middle class, and other perceived enemies of the state. The Khmer Rouge believed that these individuals were a threat to their rule and that they needed to be eliminated in order to create a pure socialist society. The executions were carried out in secret, and the bodies of the victims were often buried in mass graves.
The Khmer Rouge also established a network of prisons and interrogation centers, where suspected enemies of the state were tortured and executed. The most notorious of these prisons was S-21, which was located in Phnom Penh and was responsible for the deaths of an estimated 17,000 people.
Aftermath of the Genocide
In 1979, the Khmer Rouge was ousted from power by the Vietnamese army, which had invaded Cambodia in response to the Khmer Rouge’s attacks on Vietnamese villages. The Vietnamese installed a new government in Cambodia, which was led by Heng Samrin, a former Khmer Rouge official who had defected to the Vietnamese side.
Trial of Khmer Rouge Leaders
In the years following the genocide, there were several attempts to bring the Khmer Rouge leaders to justice. In 2007, the Extraordinary Chambers in the Courts of Cambodia (ECCC) was established to try senior Khmer Rouge leaders for crimes against humanity, war crimes, and genocide. The ECCC has since tried several senior Khmer Rouge leaders, including Nuon Chea, the former deputy secretary of the Khmer Rouge, and Khieu Samphan, the former head of state.
In 2018, the ECCC convicted Nuon Chea and Khieu Samphan of genocide and sentenced them to life in prison. The convictions were seen as a significant step towards justice for the victims of the genocide and their families.
