Khmer History

Immediately after its victory, the CPK ordered the evacuation of all cities and towns, sending the entire urban population into the countryside to work as farmers, as the CPK was trying to reshape society into a model that Pol Pot had conceived.

Thousands starved or died of disease during the evacuation and its aftermath. Many of those forced to evacuate the cities were resettled in newly created villages, which lacked food, agricultural implements, and medical care. Many who lived in cities had lost the skills necessary for survival in an agrarian environment. Thousands starved before the first harvest. Hunger and malnutrition—bordering on starvation—were constant during those years. Most military and civilian leaders of the former regime who failed to disguise their pasts were executed.

Within the CPK, the Paris-educated leadership—Pol Pot, Ieng Sary, Nuon Chea, and Son Sen—were in control. A new constitution in January 1976 established Democratic Kampuchea as a Communist People's Republic, and a 250-member Assembly of the Representatives of the People of Kampuchea (PRA) was selected in March to choose the collective leadership of a State Presidium, the chairman of which became the head of state.

Prince Sihanouk resigned as head of state on April 4. On April 14, after its first session, the PRA announced that Khieu Samphan would chair the State Presidium for a 5-year term. It also picked a 15-member cabinet headed by Pol Pot as prime minister. Prince Sihanouk was put under virtual house arrest.

The new government sought to completely restructure Cambodian society. Remnants of the old society were abolished and religion, particularly Buddhism and Catholicism, was suppressed. Agriculture was collectivized, and the surviving part of the industrial base was abandoned or placed under state control. Cambodia had neither a currency nor a banking system.

Life in 'Democratic Kampuchea' was strict and brutal. In many areas of the country people were rounded up and executed for speaking a foreign language, wearing glasses, scavenging for food, and even crying for dead loved ones. Former businessmen and bureaucrats were ruthlessly hunted down and killed along with their entire families; the Khmer Rouge feared that they held beliefs that could lead them to oppose their regime. A few Khmer Rouge loyalists were even killed for failing to find enough 'counter-revolutionaries' to execute.

Solid estimates of the numbers who died between 1975 and 1979 are not available, but it is likely that hundreds of thousands were brutally executed by the regime. Hundreds of thousands died of starvation and disease (both under the CPK and during the Vietnamese invasion in 1978). Some estimates of the dead range from 1 to 3 million, out of a 1975 population estimated at 7.3 million. The CIA estimated 50,000–100,000 were executed and 1.2 million died from 1975 to 1979.

Democratic Kampuchea's relations with Vietnam and Thailand worsened rapidly as a result of border clashes and ideological differences. While communist, the CPK was fiercely pro-Cambodia, and most of its members who had lived in Vietnam were purged. Democratic Kampuchea established close ties with the People's Republic of China, and the Cambodian-Vietnamese conflict became part of the Sino-Soviet rivalry, with Moscow backing Vietnam. Border clashes worsened when Democratic Kampuchea military attacked villages in Vietnam. The regime broke off relations with Hanoi in December 1977, protesting Vietnam's alleged attempt to create an Indochina Federation. In mid-1978, Vietnamese forces invaded Cambodia, advancing about 30 miles (48 km) before the arrival of the rainy season.

The reasons for Chinese support of the CPK was to prevent a pan-Indochina movement, and maintain Chinese military superiority in the region. The Soviet Union supported a strong Vietnam to maintain a second front against China in case of hostilities and to prevent further Chinese expansion. Since Stalin's death, relations between Mao-controlled China and the Soviet Union were lukewarm at best. In the late 1970s and early 1980s, China and Vietnam would fight the brief Sino-Vietnamese War over the issue.

In December 1978, Vietnam announced formation of the Kampuchean United Front for National Salvation (KUFNS) under Heng Samrin, a former DK division commander. It was composed of Khmer Communists who had remained in Vietnam after 1975 and officials from the eastern sector—like Heng Samrin and Hun Sen—who had fled to Vietnam from Cambodia in 1978. In late December 1978, Vietnamese forces launched a full invasion of Cambodia, capturing Phnom Penh on January 7, 1979 and driving the remnants of Democratic Kampuchea's army westward toward Thailand.

On January 10, 1979, Communist Vietnam installed Heng Samrin as head of state in the new People's Republic of Kampuchea (PRK). The Vietnamese army continued its pursuit of Pol Pot's Khmer Rouge forces. At least 600,000 Cambodians displaced during the Pol Pot era and the Vietnamese invasion began streaming to the Thai border in search of refuge.

The international community responded with a massive relief effort, for these refugees only, coordinated by the United States through UNICEF and the World Food Program. More than $400 million was provided between 1979 and 1982, of which the United States contributed nearly $100 million dollars. At one point, more than 500,000 Cambodians were living along the Thai and Cambodian border and more than 100,000 in holding centers inside Thailand. Yet the biggest contribution of humanitarian aid to the bulk of the Cambodian population came from then impoverished Vietnam as well as other Eastern Block countries.
