Bohemond VI of Antioch

Bohemond VI of Antioch (ca. 1237–1275), called the Fair (le Beau), was the Prince of Antioch and Count of Tripoli from 1251 until his death. He ruled while Antioch was caught between the warring empires of the Mongols and the Egyptian Mamluks. In 1268 Antioch was captured by the Mamluks, and he was thenceforth a prince in exile. He was succeeded by his son Bohemond VII, nominal prince of Antioch (though Antioch had ceased to exist) and count of Tripoli.
