Formation of Impact of Disputed Political Discourse of " Domain of Religion" on the political Rivalries of Islamic Republic of Iran

Domain of Religion is one of the most important components of Political Discourse whose surrounding disputes besides other factors has seriously affected political rivalries in the Islamic Republic of Iran. By using ideas of David Sanders and by completing and revising them, this paper has examined dimensions of this effect in four areas of regime change, change of government, peaceful challenges and non-peaceful challenges. Of course, the main issue is study of the aforementioned effect on peaceful challenges each of which, directly and indirectly, maximally and minimally can be expressed within creeds, stands, approaches, establishment of new parties and events. Also, by dividing ages of the Islamic Republic of Iran, dispute about
domain of religion has been examined in four periods of establishment, stabilization, reconstruction, reforms and fundamentalism from the viewpoint of the most important thinkers of political discourse analogous to political factions. This paper believes that dimensions of this effect have influenced the order, regularity or irregularity of political rivalries. In these ages, tension and dispute stands lower in the second period of reconstructive state and the first period of fundamentalist state and higher in political rivalries in the establishment period, in the first period of reforms and in second period of fundamentalism, where with the reduced or decreased level of dispute, domain of religion has reliable link besides other factors.
