The Impact of Shāhnāmeh Agreements on the Transfer of Iranshahri Thought to the Islamic Period (with Emphasis on the Images of Baysanghari Shahnameh)

The continuity of Iranshahri thought in the transition to the Islamic period is a key factor in the continuity of Iranian history and culture. This idea, in spite of the transformation and rupture that was found in the appearance of sovereignty over Iran, has been going on, unlike literature (two centuries of silence), without stagnation, to the extent that in passing through the political history of this land, the ancient idea of ​​Iranshahri was transferred; in this regard, the continuation of the "national unity" section became a solid foundation for political decisions. The achievement of these decisions appears in written works and in the context of "policy writing". Since the course of the history of political writing in Iran has not been inscribed, the prominence of this process and its connotation for understanding political history and benefiting from this idea in policy-making has been neglected. "Ferdowsi’s Shāhnāmeh" is an exceptional literary artwork in worldwide literature that in connection with the ancient gods and political thought of Iranshahri has been able to reflect the relevant political sources of the ancient period in its treasurable values. The resources that have reached the hands of the sage Abolghasem Ferdowsi have gain power to his loyal poet in so that this experience is alike to a vast palace that has gained peace in the concept of the political letter. In the meantime, it should be said: It is important to analyze the role of Ferdowsi Shahnameh in the transfer of Iranshahri ideas to the Islamic period and its channels of influence. Shahnameh of Baysanghari is one of the magnificent works of the Islamic period that has been created based on Shahnameh. This study seeks to analyze Ferdowsi's political point of view by processing the "treaty" and "guarantee" as a capability in the implementation of the treaty in Shahnameh and finally the effect of the characteristics of the treaties in the drawings of Baysanghari Shahnameh has been reflected upon.
