Existence of lots of Alavian in Tabarestan and Dylmstan because of their inaccessibility to oppressive caliphs and then familiarity of Dylaman with Sadat ideas and existence of a common enemy like Abbasian, degenerating of Alavian free-government, weakening their children, inefficiencies of the central government, losing the power of the Samanids, weakness of local government and releasing the uncontrolled fighting forces of Gils and Dylm caused the local government emerged from each side and became independent. The idea of a strong state and the revival of the ancient heritage of Iran permeated among many ethnic groups, that in the meantime, the success of this local ideal idea most of all was allotted to the Shia family of Buey that appeared among the rebellious tribes of Dylm and could put not only Iran but also to Baghdad under their own authority.
