The Paykar (Struggle) Organization was formed in 1979 from a Mojahedin splinter group that advocated the total separation of the religious establishment and the state. It considered Khomeini's policies backward and damaging to Iran's long-term socioeconomic development. The Paykar, perceived by other leftist groups as a dogmatic movement, called for an end to the Iran-Iraq War, viewing it as a diversionary tactic "waged by two reactionary and unpopular regimes." In 1982, when several Paykar leaders were arrested, the organization ceased to function overtly, but in 1987 it was still suspected of operating underground cells in major Iranian cities.
