Hethum I[1] (Armenian: Հեթում Ա; 1213 – 21 October 1270) ruled the Armenian Kingdom of Cilicia (also known as "Little Armenia") from 1226 to 1270. He was the son of Constantine of Baberon (d. 1263) and Princess Alix Pahlavouni of Lampron (a third-cousin of Leo I) and was the founder of the dynasty which bears his name: the Hethumids also known as the House of Lampron. Having accepted the suzerainty of the Mongol Empire, Hethum himself traveled to the Mongol court in Karakorum, Mongolia,[2] a famous account of which is given by Hethum's companion, the historian Kirakos Gandzaketsi, in his History of Armenia. He allied with the Mongols to fight against the Muslim Mamluks and also encouraged other Crusader states to do the same.
