Before his rise to kingship, Nusrat al-Din Ahmad had spent much time as a hostage at the court of the Ilkhanate.
[2] The historical chronicle of Tajarib al-Salaf, a Persian translation and modification of the Arabic Kitab al-fakhri, was presented to Nusrat al-Din Ahmad by Hindushah Nakhjavani after 1323.
The second work—also a historical chronicle—was the Mu‘jam fi athar muluk al-Ajam by Sharaf al-Din Fazlullah Qazvini.
[3][4] In the Mu‘jam, Nusrat al-Din Ahmad is regarded a "the greatest sovereign, the ruler of the Persian kings, the Chosroes of Iran, heir to the Kayanid sovereignty, the Jamshid of the age, the Darius of the time, eraser of the traces of the Barmakids," thus demonstrating the Iranian cultural environment that he was part of.
[5] He is likewise portrayed in a positive light by the Ilkhanate court historians Shabankara'i and Hamdallah Mustawfi.
