The history of the communist movement in Cambodia can be divided into six phases: the emergence of the Indochinese Communist Party (ICP), whose members were almost exclusively Vietnamese, before World War II; the ten-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 (Pol Pot after 1976) and other future Khmer Rouge leaders gained control of its apparatus; the revolutionary struggle from the initiation of the Khmer Rouge insurgency in 1967-68 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.
