Tabaristan

Tabaristan was a mountainous Caspian region later called Mazandaran, ruled by the Iranian Bavandid dynasty from Amol. In 1337 Hasan II held the throne as the last ruler of the main Bavandid line.

In 1349 Hasan executed a powerful noble, provoking a revolt; the sons of his brother-in-law Kiya Afrasiyab murdered him in a bath, and Afrasiyab seized power. The sayyid Mir-i Buzurg defeated Afrasiyab in 1359 and founded the Marashi dynasty. Afrasiyab's line returned in 1393 with Timur's help, but Shah Ismail conquered its territories in 1504.
