Transfer and Change in Political Thought Farr-i Izadi,from Ancient Iran to Islamic era of Iran Based on Iranian Scholar's Trends of thought

Transferring the theory of Farr-i Izadi from ancient Iran to Islamic era of Iran is one the most important components that helped in formation of the theory “Ideal King” in Islamic era. Numerous papers have been written on Farr-i Izadi,however few works have been done on reproduction and changes of Farr-i Izadi in Islamic era of Iran, and yet in general review no comprehensive research has ever been done so far. In the present paper we tried to explain political thought Farr-i Izadi in earlier Islamic era in Iran, i.e. invasion of Muslim Arabs to invasion of Mongols, based on Iranian scholars’ trends of thought. It is quite obvious, the entrance of Islam in Iran gave Islamic approachesto methods of ruling, so that the first Iranian governmentswere seeking historical –mythological ancestry,in order to receive Farr-i Izadi (divine glory),and alsoallegiance to Caliph represented their legitimacy. But such legitimacy was somehow different from general structure of Farr-i Izadi in public opinion. As it is described in the present paper, the allegiance which represents legitimacy was considered the crucial difference between Sultan and Caliph. With the emergence of Turks in political system of Iran,seeking genealogy charts for Iranian kings was abandoned and this intellectual change of scholars led to the first intellectual dissociation in Iranian society.
