The Iranian intellectual Muhammed Nakhshab is credited with the first synthesis between Shi'ism and European socialism. Nakhshab's movement was based on the tenet that Islam and socialism were not incompatible since both sought to accomplish social equality and justice. His theories had been expressed in his B.A. thesis on the laws of ethics. In 1943, Nakhshab founded the Movement of God-Worshipping Socialists, one of six original member organizations of the National Front. The organization was founded through the merger of two groupings, Nakhshab's circle of high school students at Dar al-Fanoun and Jalaleddin Ashtiyani's circle of about 25 students at the Faculty of Engineering at Tehran University. The organization was initially known as League of Patriotic Muslims. It combined religious sentiments, nationalism and socialist thoughts. After the 1953 coup against the National Front-led government of Mohammad Mosaddegh, Islamic socialism in Iran took a more radical turn, with the People's Mujahedin of Iran formed in 1965 fusing Islamic imagery and language with Marxist ideas under the influence of Ali Shariati and engaging in armed struggle against the government of the Shah of Iran, culminating in its participation in the Iranian Revolution which overthrew the Shah in 1979. However the movement fell foul of the Islamic Republic established after the Revolution, and took up arms against the new government.
