While no date has been established for the origin of the Soran Emirate, Kurdish historian Sharaf al-Din Bitlisi mentions the Emirate in Sharafnama in 1597 as established by a shepherd by the name of "Isa". Bitlisi claims that villagers quickly followed the popular Isa and they attacked the Rewan Castle where they established themselves. They took the name "Soran" meaning "from red" after the red stones near the castle. Year later, during the Battle of Chaldiran in 1514 between the Ottomans and the Safavids, the Emirate was able to conquer land between Erbil and Kirkuk. In 1534, Emir Ezaddin Sher was executed by Suleiman the Magnificent for his treatment of the Emperor's servants and the Emirate was given to Yazidis led by Hussein Beg who ruled as a brutal tyran. He was soon toppled by the family of the previous Emir led by Emir Saifaddin who himself was executed by the Emperor in Constantinople, pushing the Emirate into anarchy.
