Kampuchea, officially Democratic Kampuchea (DK) from 1976 onward, was the Cambodian state from 1975 to 1979, under the totalitarian dictatorship of Pol Pot and the Communist Party of Kampuchea (CPK), commonly known as the Khmer Rouge (KR). It was established following the Khmer Rouge's capture of the capital Phnom Penh, effectively ending the United States-backed Khmer Republic of Lon Nol. After Vietnam took Phnom Penh in 1979, it was disestablished in 1982 with the creation of the CGDK in its place.
From 1975 to 1979, the Khmer Rouge's one-party regime killed millions of its own people through mass executions, forced labour, and starvation, in an event which has come to be known as the Cambodian genocide. The killings ended when the Khmer Rouge were ousted from Phnom Penh by the Vietnamese army.
The Khmer Rouge subsequently established a government-in-exile in neighbouring Thailand and retained Kampuchea's seat at the United Nations (UN). In response, Vietnamese-backed communists created a rival government, the People's Republic of Kampuchea, but failed to gain international recognition. In 1982, the Khmer Rouge established the Coalition Government of Democratic Kampuchea (CGDK) with two non-communist guerrilla factions, broadening the exiled government of Democratic Kampuchea. The exiled government renamed itself the National Government of Cambodia in 1990, in the run-up to the UN-sponsored 1991 Paris Peace Agreements.
