The idea of religious democracy as emerging from the thinking style of leaders of the Islamic republic, is going to create an ideal relationship between democracy and religion. The present paper will explain the religious democracy in the ideologies of leaders of the Islamic republic of Iran (Imam Khomeini and Ayatollah Khamenei), within three theoretical, principles and components of religious democracy, and practical realization principles of religious democracy areas. In the thoughts of Imam Khomeini and ayatollah Khamenei there is a firm link between religion and politics, and democracy originates from religion. Since democracy is in the length of God's leadership, and people have chosen religion as their democracy framework, the link between Islam and democracy materializes. The leaders of the Islamic republic believe in human dignity and in the role of public participation of all men and women in realization of democracy. For them, participation in elections and political issues is both, a right, and an obligation. Thus, it can be claimed that elections have a key position in the realization of democracy. In fact, even the protector of the Islamic juristics who in the thought of Shiism and during the absence of Imam Zaman is in charge of religious affairs is elected through the votes of the Constituent Assembly (who are elected by people). Therefore, in the thoughts of leaders of the Islamic republic there is a link between the components and bases of Islam and democracy.
