Ziyarid dynastyThe Ziyarid dynasty (زیاریان) was an Iranian dynasty of Gilaki origin that ruled Tabaristan from 931 to 1090 during the Iranian Intermezzo period. The empire rose to prominence during the leadership of Mardavij. After his death, his brother Vushmgir and his Samanid allies led the dynasty in wrestling for control over territory against the Buyids in the early- to mid-10th century. When Vushmgir died, his sons Bisutun and Qabus fought for influence. Qabus would eventually outlive his brother and ruled the kingdom.
