Mahmud Ghazan was the seventh ruler of the Mongol Empire's Ilkhanate division in modern-day Iran from 1295 to 1304. 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 il khans, 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: Iran, Iraq, Anatolia, and the South Caucasus.
Ghazan (center) was born as a Buddhist, and converted to Islam as part of a military agreement upon accession to the throne.

The Ilkhanate or Il-khanate, ruled by the Il-Khans or Ilkhanids, and known to the Mongols as Hülegü Ulus, was a Mongol khanate established from the southwestern sector of the Mongol Empire. The Ilkhanid realm was officially known as the Land of Iran or simply Iran. It was established after Hülegü, the son of Tolui and grandson of Genghis Khan, inherited the West Asian part of the Mongol Empire after his brother Möngke Khan died in 1259.
