The People's Republic of Kampuchea (PRK; Khmer: សាធារណរដ្ឋប្រជាមានិតកម្ពុជា Sathéaranakrâth Pracheameanit Kâmpŭchéa) was founded in Cambodia by the Salvation Front, a group of Cambodian leftists dissatisfied with the Khmer Rouge, after the overthrow of Democratic Kampuchea, Pol Pot's government. Brought about by an invasion from the Socialist Republic of Vietnam, which routed the Khmer Rouge armies, it had Vietnam and the Soviet Union as its main allies.
