Arghun

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.
