Islamic revolution of Iran in 1357 united many groups,social castes and associations with different beliefs which all were oppossed to the Shah’s regime. Islamic revolution of Iran like other revolutions did not preserve this coalition and after wining the revolution, this coalition did not continue. According to the teories of Kerin Berinton, after a revolution’s victory, moderates come to work. But after while, they are accused of patoromizing the old regime and wing the revolutionary methods by the radicals. Consequently, the radicals win over moderates and take full control of the new system. Islamic revolution of Iran is not the exception. The events that occured between Bahman 22, 1357 until Tir 1360, have been the exact reflection of revolutionary struggle in the process of Islamic revolution of Iran.
