People's Republic of Kampuchea

1979 CE – 1989 CE · capital Phnom Penh

The Vietnamese-backed Cambodian state established after the overthrow of the Khmer Rouge in 1979, isolated internationally for a decade.

Origins

After Vietnam invaded Democratic Kampuchea, its forces took Phnom Penh on 7 January 1979, and the People's Republic of Kampuchea was proclaimed, led by the Kampuchean United Front for National Salvation, a group of former Khmer Rouge cadres who had defected to Vietnam, including Heng Samrin and Hun Sen.

Rule and society

The PRK was a one-party state under the Kampuchean People's Revolutionary Party, with Vietnamese troops and advisers. It reopened schools, markets, pagodas and Phnom Penh itself, and gathered evidence of Khmer Rouge crimes at Tuol Sleng. It faced famine in 1979 to 1980 and a guerrilla war from a coalition of the Khmer Rouge, royalists and republicans, which held Cambodia's UN seat.

Decline and legacy

As Soviet aid declined, Vietnam prepared to withdraw its troops, completed in 1989. That year the state was renamed the State of Cambodia, dropping some socialist features to prepare for a negotiated settlement.
