After the fall of the Pol Pot regime of Democratic Kampuchea, Cambodia was under Vietnamese occupation and a pro-Hanoi government, the People's Republic of Kampuchea was established. A civil war raged during the 1980s opposing the government's Kampuchean People's Revolutionary Armed Forces against the Coalition Government of Democratic Kampuchea, a government in exile composed of three Cambodian political factions: Prince Norodom Sihanouk's Funcinpec party, the Party of Democratic Kampuchea (often referred to as the Khmer Rouge) and the Khmer People's National Liberation Front (KPNLF).
