Mazandaran: During Shams al-Din 'Ali's reign, a supporter of Hasan Juri named 'Izz al-Din, with a group of fellow adherents, returned to his homeland in Mazandaran. They were apparently unable to accept the moderate tone taken by the Sabadars in Sabzavar. 'Izz al-Din died en route, leaving his son Sayyid Qivan al-Din (also known as Mir-i Buzurg) to lead the group. They arrived in Amul and set up a state together with Kiya Afrasiyab, a son of a Hasan Chulabi, who had destroyed the local Bavand dynasty in 1349. Like the Sarbadars, conflict soon erupted in this state between the secular rulers and the dervishes; the latter eventually won. Destroyed in 1392 by Timur, it emerged once more after his death, but only for a brief time.
