Rashid-al-Din Hamadani
It is claimed that Bolad assisted Rashid-al-Din Hamadani to write Universal History because he knew Mongolian history very well. Under Öljeitü (1304–16), Bolad achieved great influence as chingsang (chengxiang, grand councillor) and agha (Classic Mongolian: aqa, meaning elder). He was along with Chupan of the Suldus, and Kutlushah of the Qonkhoton served the Ilkhan as main advisors.
