 Hasan Beg's "most enduring legacy is historiographical".Later Safavid historians (e.g.Iskander Beg Munshi) used material from Hasan Beg's "Aḥsān al-tavārikh" in the sections of their works related to the rule of king Tahmasp I. Hasan Beg's work was used by Fazli Isfahani Khuzani for his "Afżal al-tavārikh" and also survives in "a very late cluster of mostly anonymous semi-fictional accounts of early Safavid history such as the "ʿĀlamārā-ye Shah Esmāʿil"".
