Mahmud Ghazan was the seventh ruler of the Ilkhanate from 1295 to 1304, division of the Mongol Empire based in modern-day Iran. He was the son of Arghun, grandson of Abaqa Khan and great-grandson of Hulegu Khan, continuing a long line of rulers who were direct descendants of Genghis Khan. Considered the most prominent of the Ilkhans, he is perhaps best known for converting to Islam and meeting Imam Ibn Taymiyya in 1295 when he took the throne, marking a turning point for the dominant religion of the Mongols in West Asia.
