The history of the communist movement in Cambodia can be divided into six phases, namely the emergence before World War II of the Indochinese Communist Party (ICP), whose members were almost exclusively Vietnamese; the 10-year struggle for independence from the French, when a separate Cambodian communist party, the Kampuchean (or Khmer) People's Revolutionary Party (KPRP), was established under Vietnamese auspices; the period following the Second Party Congress of the KPRP in 1960, when Saloth Sar gained control of its apparatus; the revolutionary struggle from the initiation of the Khmer Rouge insurgency in 1967–1968 to the fall of the Lon Nol government in April 1975; the Democratic Kampuchea regime from April 1975 to January 1979; and the period following the Third Party Congress of the KPRP in January 1979, when Hanoi effectively assumed control over Cambodia's government and communist party.
