Cambodia
Khmer Rouge
20th Century · 1914 – 2000
Cambodia is a country in mainland Southeast Asia, between Thailand, Laos and Vietnam. It was a French protectorate from 1863 and won independence in 1953. In the 1960s it was drawn into the wider Indochina wars. The Khmer Rouge, the Cambodian communist movement led by Pol Pot, took power on 17 April 1975 and ruled until January 1979.
Under the regime of Democratic Kampuchea, the cities were emptied and money, markets, schools and religion were abolished. The population was forced into agricultural labour. Historians estimate that well over a million people died from execution, forced labour, starvation and disease, and the regime also persecuted minorities such as the Cham and ethnic Vietnamese. A Vietnamese invasion ended the regime, but the Khmer Rouge fought on until the late 1990s. The period still shapes Cambodian politics, and a UN-backed tribunal later tried some surviving leaders.
Things happened, and the rest is history
French protectorate and independence
EventWhat happened
In 1863 King Norodom accepts a French protectorate over Cambodia, which later becomes part of French Indochina. After the Second World War, King Norodom Sihanouk presses France for self-rule. Cambodia becomes fully independent in 1953.
The rest is history
Independence left Sihanouk as the dominant figure in Cambodian politics. He abdicated the throne in 1955 so that he could lead the state as a politician. The colonial period left a small educated elite, some of whom studied in Paris and later joined the communist movement. The Geneva Conference of 1954 confirmed Cambodia's separate status outside Vietnam.

Sihanouk's neutrality and the Vietnam War spillover
EventWhat happened
Through the 1960s Sihanouk tries to keep Cambodia neutral, but North Vietnamese forces use border areas as bases and supply routes. In 1969 the United States begins secret bombing of these areas. Cambodian communists, called the Khmer Rouge by Sihanouk, fight a small rebellion in the countryside.
The rest is history
The bombing and the war's spread destabilised Cambodia's countryside. Historians debate how far it caused the Khmer Rouge's growth, but most agree it helped their recruitment. The war's pressures also weakened Sihanouk's balancing policy. This set the stage for the coup of 1970.

The 1970 coup and civil war
EventWhat happened
On 18 March 1970, while Sihanouk is abroad, the National Assembly removes him and General Lon Nol takes power. Sihanouk, in Beijing, then allies with the Khmer Rouge. In spring 1970 American and South Vietnamese troops enter eastern Cambodia, and a civil war begins.
The rest is history
Sihanouk's backing gave the Khmer Rouge popular legitimacy among rural people loyal to the king. The Lon Nol government's forces were poorly led and lost ground. The Khmer Rouge grew from a small force into a large army. By 1973 American bombing had been halted by Congress, and the republic fell in 1975.

The fall of Phnom Penh, 17 April 1975
EventWhat happened
On 17 April 1975 Khmer Rouge troops enter Phnom Penh, ending the civil war. Within days they order the city's residents, swollen with refugees, to leave on foot. Other towns are emptied too. The new state, Democratic Kampuchea, is proclaimed in 1976.
The rest is history
The evacuations separated families and caused many deaths among the sick and elderly. The leadership, known as Angkar, was led in practice by Pol Pot, whose identity was kept hidden at first. Money, markets, schools and religious practice were abolished. The country was reorganised around forced agricultural labour.

Forced labour, famine and the security prisons
EventWhat happened
From 1975 to 1979 most Cambodians are put into agricultural cooperatives and work long hours on irrigation and rice schemes with little food. The regime seeks out supposed enemies, including former officials, educated people and later its own cadres. Suspects are sent to security centres, of which Tuol Sleng (S-21) in Phnom Penh is the best documented.
The rest is history
Staff at S-21 kept detailed records, including confessions and photographs, and only a handful of prisoners are known to have survived. Estimates of total deaths under the regime vary, but most scholars give figures between about 1.5 and 2 million. Minorities such as the Cham, Vietnamese and Chinese were targeted. The records have been central to later research and trials.

The Vietnamese invasion of 1978-79
EventWhat happened
Border clashes between Democratic Kampuchea and Vietnam grow through 1977 and 1978. In December 1978 Vietnamese forces and Cambodian rebels invade. They take Phnom Penh on 7 January 1979, and the Khmer Rouge leaders flee west.
The rest is history
Vietnam installed a new government, the People's Republic of Kampuchea, led by Heng Samrin and later Hun Sen. The Khmer Rouge kept fighting from the Thai border. From 1982 they were part of the Coalition Government of Democratic Kampuchea, with Sihanoukist and noncommunist factions, which kept Cambodia's UN seat for years with backing from China and others. Famine eased only slowly. Vietnamese troops stayed until 1989.

The Paris Peace Agreements and UN administration
EventWhat happened
On 23 October 1991 Cambodian factions and other states sign the Paris Peace Agreements. The United Nations Transitional Authority in Cambodia (UNTAC) then supervises key areas of administration, while the existing Cambodian government keeps much of its control, and holds elections in May 1993. The Khmer Rouge boycott the process.
The rest is history
A coalition government and a restored monarchy under Sihanouk followed. The Khmer Rouge declined through defections and Pol Pot's death in April 1998. The movement's last leaders surrendered by 1999. Peace came to the country only at the end of the decade.

The tribunal for the Khmer Rouge
EventWhat happened
After agreements between Cambodia and the United Nations, the Extraordinary Chambers in the Courts of Cambodia begin work in 2006. They try a small number of senior surviving figures. In 2010 Kaing Guek Eav, known as Duch, who ran S-21, is convicted.
The rest is history
Later judgments convicted Nuon Chea and Khieu Samphan of crimes against humanity. Nuon Chea was also convicted of genocide against both the Vietnamese and the Cham, while Khieu Samphan was convicted of genocide against the Vietnamese only. Many senior leaders, including Pol Pot, died before trial. The court's cost and limited reach have been debated. It closed its main work in the early 2020s.

The belief that the American bombing alone created the Khmer Rouge
Popular beliefThe legend
A common claim is that the American bombing of Cambodia, begun in secret in 1969, single-handedly caused the rise of the Khmer Rouge and so explains the genocide. In this telling the regime was simply a response to the bombs.
The rest is history
The bombing killed many civilians and helped the Khmer Rouge recruit, and historians such as Kiernan stress this. But the movement had existed since the 1950s and had a long-formed ideology shaped by Paris-educated leaders, the Vietnam War and Cambodian politics. Scholars also point to the 1970 coup, Sihanouk's alliance with the rebels, and the regime's own choices. The debate is about weighting, not about whether the bombing mattered.

The belief that the regime killed all educated people for wearing glasses
Popular beliefThe legend
It is often said that the Khmer Rouge killed anyone who wore glasses or could read, as a sign of being educated. In this telling, spectacles alone were a death sentence.
The rest is history
Survivor accounts and research show that the regime did target teachers, officials, monks and professionals as supposed enemies, and that educated people often hid their background. But there is no evidence of a rule that glasses alone meant death. Persecution followed class background, ethnic identity and suspected disloyalty, and later purges hit the party's own cadres. The S-21 archive shows that killings followed forced confessions, not appearance.
