On New Year's Day 1975, communist troops launched an offensive that, in 117 days of the hardest fighting of the war, destroyed the Khmer Republic. Simultaneous attacks around the perimeter of Phnom Penh pinned down Republican forces, while other Khmer Rouge units overran fire bases controlling the vital lower Mekong resupply route. A U.S.-funded airlift of ammunition and rice ended when Congress refused additional aid for Cambodia. Phnom Penh surrendered on April 17, 1975--5 days after the U.S. mission evacuated Cambodia.

Many Cambodians welcomed the arrival of peace, but the Khmer Rouge soon turned Cambodia--which it renamed Democratic Kampuchea (DK)--into a land of horror. Immediately after its victory, the new regime ordered the evacuation of all cities and towns, sending the entire urban population out into the countryside to till the land. Thousands starved or died of disease during the evacuation. Many of those forced to evacuate the cities were resettled in new villages, which lacked food, agricultural implements, and medical care. Many starved before the first harvest, and hunger and malnutrition--bordering on starvation--were constant during those years. Those who resisted or who questioned orders were immediately executed, as were most military and civilian leaders of the former regime who failed to disguise their pasts.

Within the CPK, the Paris-educated leadership--Pol Pot, Ieng Sary, Nuon Chea, and Son Sen--was in control, and Pol Pot was made Prime Minister. Prince Sihanouk was put under virtual house arrest. The new government sought to restructure Cambodian society completely. Remnants of the old society were abolished, and Buddhism 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. The regime controlled every aspect of life and reduced everyone to the level of abject obedience through terror. Torture centers were established, and detailed records were kept of the thousands murdered there. Public executions of those considered unreliable or with links to the previous government were common. Few succeeded in escaping the military patrols and fleeing the country. 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 more died of starvation and disease--both under the Khmer Rouge and during the Vietnamese invasion in 1978. Estimates of the dead range from 1.7 million to 3 million, out of a 1975 population estimated at 7.3 million.

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 anti-Vietnamese, and most of its members who had lived in Vietnam were purged. Democratic Kampuchea established close ties with China, and the Cambodian-Vietnamese conflict became part of the Sino-Soviet rivalry, with Moscow backing Vietnam. Border clashes worsened when Democratic Kampuchea's military attacked villages in Vietnam.

In mid-1978, Vietnamese forces invaded Cambodia, advancing about 30 miles before the arrival of the rainy season. 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.
