Like the Mojahedin, several Marxist political parties have maintained clandestine cells inside the country. Tudeh leaders, who managed to escape the government's mass arrests and forcible dissolution of their party in early 1983, reestablished the Tudeh in exile in the German Democratic Republic (East Germany). The Fadayan Majority, which later in 1983 suffered the same fate as the Tudeh, was decimated by government persecution its surviving members eventually joined the Tudeh. The Komala (Komala-ye Shoreshgari-ye Zahmat Keshan-e Kordestan-e Iran, or Committee of the Revolutionary Toilers of Iranian Kordestan), a predominantly, but not exclusively, Kurdish party, had rejected as early as 1979 the Tudeh and Fadayan Majority policy of cooperation with the regime and continued to fight against central government forces up to the end of 1985, when it was forced to retreat to Iraqi Kurdistan. The Fadayan Minority had joined the Mojahedin uprising in 1981 and consequently lost most of its cadres in the ensuing confrontation with the regime. It has party offices in several West European cities and on university campuses in the United States. The Paykar, which also joined the Mojahedin's unsuccessful rebellion, was largely destroyed by 1982, although secret cells were believed still to exist in 1987.
