A long-lived Iranian dynasty claiming Sasanian descent that ruled parts of the mountainous Caspian region of Tabaristan for nearly 700 years, alternating between full independence and vassalage to stronger regional powers (Abbasids, Samanids, Buyids, Ilkhanids).
Ended in 1349 after nearly seven centuries — the second-longest-ruling dynasty in Iranian history after the Baduspanids.
