Al-Ma'ali Abu Mansour Manouchehr Ibn Qaboos Ziari was the fifth ruler of Al-Ziyar who ruled Jorjan, Tabarestan, Qoms and Gilan between 403 and 420 AH. Manouchehr was the son of Qaboos bin Vashmgir, who had previously lost his territory and lived for many years in the Samanid court in Khorasan. During this period, Manouchehr spent some time in Majdal Doleh Dailami's army and even took part in one of the battles against his father. After Qaboos succeeded in returning to power, he appointed Manouchehr to rule Gilan. Qaboos became suspicious at the end of his life and killed many of those around him, so some of his commanders killed him and invited Manouchehr to accept the government. After accepting the Emirate of Ziari, Manouchehr arrested his father's main killers and retaliated. Manouchehr Ziari is the first emir of this dynasty who did not have an independent government. From the very beginning of his emirate, he obeyed Sultan Mahmud of Ghazni and married his daughter. Thus, Manouchehr and his successors were forced to pay annual ransoms to the Sultan, and from then on, the Ziari dynasty entered a period of decline and gradually lost its former power. Manouchehr did not wage significant warfare during his relatively long reign and never withdrew from his territory with his troops, although he provided military assistance to rebel opponents against the Buyids. At the beginning of his rule, Manouchehr paid attention to the Zaydi religion and established contacts with the Shiites of Gilan. Sultan Mahmud of Ghazni invaded Manouchehr's territory, probably because of Manouchehr's support for the Shiites, and forced Manouchehr to pay sums to escape the sultan's attack. Manouchehr paid less attention to writers and poets than Qaboos, and the literature of the Ziari court moved to Ghaznavid during this period.
