Shahriyar IV

Shahriyar IV (Persian: شهریار), also known by his honorific title Husam al-Dawla (حسام الدوله), was the king of the Bavand dynasty of Mazandaran, ruling from 1074 to 1114.

After having succeeded his father Qarin II in 1074, Shahriyar IV immediately moved the capital to Sari, which it would remain till 1210.

Shahriyar was born in 1039, and in 1074, he ascended the Bavandid throne, taking the traditional title of ispahbadh of Mazandaran.

After his return to Sari, however, he began claiming the Bavand throne for himself, and started abusing his father Shahriyar and his servants.

Ahmad Sanjar was preparing for an expedition to the west in order to take control of Gorgan, but an attack made by Muhammad Khan on the Seljuk borders, forced Ahmad Sanjar to move east in order to repel Muhammad Khan.
