He was the son of Arghun and Quthluq Khatun, continuing a long line of rulers who were direct descendants of Genghis Khan. Considered the most prominent of the Ilkhans, he is best known for making a political conversion to Islam in 1295 when he took the throne, marking a turning point for the dominant religion of Mongols in West Asia (Iran, Iraq, Anatolia and Trans-Caucassia). His principal wife was Kököchin, a Mongol princess (originally betrothed to Ghazan's father Arghun before his death) sent by his Khagan Kublai Khan, and escorted from the Mongol capital to the Ilkhanate by Marco Polo., The Ilkhanate, also spelled Il-khanate ("Ilkhnn" "Hulagu-yn Ulus"), was established as a khanate that formed the southwestern sector of the Mongol Empire, ruled by the Mongol House of Hulagu.

With the fragmentation of the Mongol Empire after 1259 it became a functionally separate khanate.
