Rashid al-Din
Having converted to Islam by the age of 30, Rashid al-Din became the powerful vizier of the Ilkhan, Ghazan. Later he was commissioned by Ghazan to write the "Jāmiʿ al-Tawārīkh", now considered the most important single source for the history of the Ilkhanate period and the Mongol Empire. He retained his position as a vizier until 1316.
