Imam Khomeini`s thought and conduct on and against Arrogant Despot`s Sovereignty led to IRI, appearance and reinforcement of many regional and international movements. As IRI has been based upon Imam`s political thought, in this paper it has been intended to explain and reread the principles, purposes, reasons and political conduct as an effective model for the leaders of those liberating movements to fight against tyrannical regimes permanently and powerfully. The necessity of this fundamental study would be clearly perceived with regard to the new course of Islamic awakening in Islamic countries. On findings of the paper, Imam Khomeini began and continued his unmilitary struggling conduct by following various scientific, cultural methods as a leader to execute Divine law and establish Islamic government.
