The Islamic Revolution of Iran in 1979 and the Egyptian revolution in January 2011 as two major political and social changes, can be studied and compared from different perspectives and approaches. Especially, in one of them that is the Iranian revolution, led to the victory of the Islamic stream and the continuation of a political system, and in the other, the Egyptian revolution, despite initial successes of the Muslim Brotherhood, and after taking power for a year, eventually driven out of power by a military coup when public opposition expanded, and after the repression, the Muslim Brotherhood social and political activities were banned and prohibited. Now, the question is how the Islamist movement in Iran and Egypt, led to a different results in the revolution and its subsequent events.
