Mardawij and his notions about reestablishment of Sassanid Kingdom

Ziarid Mardāwidj is known، as outstanding personage in tenth century، who comes up with the Idea of reviving the Sassanian kingdom. He has been accused of promoting the return of religion and kingdom of Iran back to Sasanian period، by Abbasian Caliphate courts historians. Despite many contradictory remarks، it is not clear، what were the motives which compelled Mardāwidj to think of such an attempt. The objective of this article is to investigate little existing data، in an explanatory-analytic method and find the possible reasons for such a conduct by Mardawij. Here it is found that، in the final five months of his reign، Mardāwidj began to oppose the Caliphate although he had a close connection with Abbassian Caliphate، similar to other Istilā amirs. Then، as a manner of acquisition of legitimacy، he introduced the idea of revival of Sassanid kingdom، in order to compensate for the loss of his political legitimacy.
