History of the Mujahideen-e Khalq (MEK)

In 1980, the MEK was under the control of Massoud Rajavi, one of the few surviving members of the MEK’s Central cadre. Although allied with Khomeini against the shah, Khomeini "disliked the MEK’s philosophy, which combined Marxist theories of social evolution and class struggle with a view of Shiite Islam that suggested Shiite clerics had misinterpreted Islam and had been collaborators with the ruling class." Rajavi became allied with Iran’s new president, Abolhassan Banisadr, elect in January 1980.
