The Principality of Antioch was one of the earliest Crusader States, founded in 1098 during the First Crusade. At the time of the Mongol advance, it was under the rule of Bohemond VI. Under the influence of his father-in-law, Hethum I, Bohemond too submitted Antioch to Hulagu in 1260. A Mongol representative and a Mongol garrison were stationed in the capital city of Antioch, where they remained until the Principality was destroyed by the Mamluks in 1268. Bohemond was also required by the Mongols to accept the restoration of a Greek Orthodox patriarch, Euthymius, as a way of strengthening ties between the Mongols and the Byzantines. In return for this loyalty, Hulagu awarded Bohemond all the Antiochene territories which had been lost to the Muslims in 1243. However, for his relations with the Mongols, Bohemond was also temporarily excommunicated by Jacques Pantaléon, the Latin Patriarch of Jerusalem, though this was lifted in 1263.
