After Vaspurakan was ceded to the Byzantine Empire , it was conquered by Seljuq Turks . Later it was ruled by Ahlatshahs , Ayyubids and Sultanate of Rum successively . In the beginning of the 13th century , part of Vaspurakan was liberated by the Mkhargrdzeli , but was then conquered by the Mongols , Seljuks , Kara Koyunlu , Iranian Safavids , and then by the Ottoman Turks ( though Nader Shah regained it during his short lived Afsharid dynasty ) .
