كيقباد الأول
Majd ad-Din was the new chief "da'i" in Syria in 1220, assuming that role from Kamāl ad-Din al-Hasan of whom very little is known. At that time the Seljuk sultanate of Rûm paid an annual tribute to Alamut, and Majd ad-Din notified the sultan Kayqubad I that henceforth the tribute was to be paid to him. Kayqubad I requested clarification from Hassan III who informed him that the monies had indeed been assigned to Syria.
