The Presence of Shiʿite Agents in the Iranian Structure of Tabarestān

The Shiʿites, who had endured a long history of conflict in their struggle to achieve power in the region, finally succeeded in Tabarestān. The formation of the ʿAlawite government of Tabarestān (250–316 AH/864–928 AD) was the Shiʿites’ response to the question posed by the ʿAbbāsid Caliphate (and that had never been answered). The ʿAbbāsids, who had come to power with the use of Shiʿite structures and on the pretext of protecting their active agents, including Yahyā ibn Zeyd (d. 125 AH/742 AD), now faced a government based on the same structure and in a territory far from the ʿAbbāsids’ reach. This increased their worry.

The presence of Muslims in Tabarestān in the first century of Islam seemed unlikely to achieve due to natural obstacles. The writings of historians show that Zoroastrianism had deep roots in this land, and the people of this region refused to convert to Islam even though it had been spreading into many other parts of Iran for more than two centuries. The Iranian religion had influenced Islam in these lands. Gardizi refers to the people of Tabarestān as “mortad [apostates],” which indicates the presence of Islam in this land.
