Farrukhan the Little (Persian: Farrukhan-e Kuchak), also surnamed the Deaf (Korbali),[1] was a member of the Dabuyid dynasty, which ruled Tabaristan as independent monarchs in the century after the Muslim conquest of Persia.
[2][1][3] According to the traditional account, the Dabuyids had established themselves as the quasi-independent rulers of Tabaristan in the 640s, during the tumults of the Muslim conquest of Persia and the collapse of the Sassanid Empire.
They owed only the payment tribute and nominal vassalage to the Arab Caliphate, and managed, despite repeated Muslim attempts at invasion, to maintain their autonomy by exploiting the inaccessible terrain of their country.
[1][4] A more recent interpretation of the sources by P. Pourshariati, however, supports that Farrukhan the Great was the one who actually established the family's rule over Tabaristan, sometime in the 670s.
Farrukhan effectively ruled Tabaristan for the next eight years, but this is not reflected in the coinage of the period, with coins struck solely in Khurshid's name from 741 on.
