Kiya Husayn II (Persian: کیا حسین), was the last ruler of the Afrasiyab dynasty, ruling from the late 15th-century till his death in 1504.
He ruled over a large part of western Mazandaran, and districts of Firuzkuh, Damavand, and Hari-rud.
During the dissolution of the Aq Qoyunlu confederation, Kiya Husayn II expanded his rule from western into central Iran, where he captured Ray and Semman.
[1] It was probably around this period that Kiya Husayn II married the Aq Qoyunlu princess Tajlu Khanum.
However, the latter committed suicide—his body was burned at Isfahan in front its inhabitants, whilst his followers in Mazandaran were slaughtered.
