Arghun, Mongol ruler in Persia (born c. 1258)

Arghun Khan was the fourth ruler of the Mongol empire's Ilkhanate division, from 1284 to 1291. He was the son of Abaqa Khan, and like his father, was a devout Buddhist. He was known for sending several emissaries to Europe in an unsuccessful attempt to form a Franco-Mongol alliance against the Muslim Mamluks in the Holy Land. It was also Arghun who requested a new bride from his great-uncle Kublai Khan. The mission to escort the young Kököchin to Arghun reportedly went with Marco Polo. Arghun died before Kököchin arrived, so Arghun's son Ghazan married her instead.
