The People's Democratic Front (Persian: جبهه دموکراتیک خلق) was an Iranian rebel group, which advocated armed struggle against the regime of Mohammad Reza Pahlavi. Prominent members of the group included Nader Shaygan-shamasbi, Marzieh Ahmadi-osku'i and Mostafa Shoa'ian. In June 1973 the organization merged into the Organization of Iranian People's Fedai Guerrillas.[1]
Ideological differences had existed between the People's Democratic Front and OIPFG. Shaygan and Shoa'ian opposed Leninism, which they saw as a deviation from Marxism. In 1974 Shoa'ian was expelled from OIPFG (by this time Shaygan was dead). After Shoa'ian's expulsion, other former People's Democratic Front cadres upheld the line of OIPFG.[1]
