Mahmud Ghazan or Qazaan the Khan of the Mongol Khanate in Middle Asia was the seventh ruler of the Mongol empire's Ilkhanate division in Iran from 1295 to 1304. Western chroniclers sometimes referred to him as Casanus or Cassanus. Ghazan converted Mongol Persia into Islam. He also delivered the only major Mongol victory over the Mamluks in 1299, though he did not have sufficient army to hold Syria. According to Britannica, Ghazan was the most prominent of the Ilkhans.
