The reputation of Burkwooh dates back to the Ismaili era, and when the Hassan Sabbah and the Fadaean, devout with their poisonous fists, drove all the Seljuk rulers and feudals to death, and at that time, a person called the head of Muzaffar, the governor of Damghan, invited him. He accepted Hassan Sabah and, since he was a rich man, he bought Alamut Castle for a price of three thousand dinars, and gave it to Hassan Sabah. He also wrote a letter to the Seljuk monarch and asked him to give him the fortress of Ghorkouh. Shaj al-Seljuk also agreed. He gave him the castle. The head of Mozaffar in the road to the fort was a great effort and spent all his wealth in this way, and he made the castle the center of propaganda of the Ismaili sect and did not condone any help from them.
