To stave off further invasion, Hethum II abandoned the cities of Marash, Behesni, and Tel Hamdoun to the Mamluks. In 1293, Hethum abdicated in favor of his brother Thoros III and entered the Franciscan monastery at Mamistra.

Hethum made the long journey to the Mongol capital, and was successfully able to request aid from the Mongols. When he returned to Armenia in 1296, further good news manifested from the Byzantine Empire, with an offer of a marital alliance. Hethum and Thoros placed Armenia under the regency of their brother Sempad, and traveled to Constantinople to bestow their sister Rita upon the Byzantine Emperor Michael IX Palaeologus. However, during their absence Sempad usurped the Armenian throne with the aid of another brother, Constantine. Hethum and Thoros were both captured in Caesarea upon their return, and imprisoned in the fortress of Partzerpert. There, Hethum was partially blinded by cauterization.

Title: Hethum II, King of Armenia

As part of this relationship, Cilician Armenia routinely supplied troops to the Mongols, cooperating in battles against the Mamluks and other elements of the Islamic empire. Hethum II took the throne in his early 20s, when his father Leon II died in 1289. At the time, Cilician Armenia was in a precarious position between major powers, balancing between friendly relations with the Christian Europeans and Byzantine Empire, aggression from the Turkish Sultanate of Rum to the west, a vassal relationship with the aggressive

Cilician Armenia was attacked by the Mamluks and since the Mongols were unable to assist, a considerable amount of territory was lost in the eastern part of the country. Hethum II then abandoned his throne to enter a Franciscan convent under the name John (an apparent homage to John of Monte Corvino), leaving official rule to his brother Thoros for two years, before Hethum regained the throne. With the rise of the Mongol Ilkhan Ghazan in 1295, Hethum II was able to again reinforce relations with the Mongols. Hethum visited Ghazan at his court, who renewed the

Content:  During the last years of Hethum's reign, largely as a result of Hethum's active support of the Mongols, the Kingdom came under increasing attack by the Mamluks, who invaded in 1266. The heavily outnumbered Armenians were unable to hold off the Mamluks at the Disaster of Mari, during which Hethum's son, Leo, was captured and imprisoned. Following the disaster, the cities of Adana, Tarsus, and Ayas were assaulted and the capital of Sis was sacked and burnt. Thousands of Armenians were massacred and 40,000 taken captive. Hethum was able to ransom his son by conceding territory to the Egyptians. In May 1268, the allied Principality of Antioch was overrun by the Egyptians. Hethum abdicated in 1270 in favor of his son Leo, and lived out the rest of his life in a monastery, as a monk.

Angus Donal Stewart points out that the source of the tradition, a medieval account by the Armenian historian Nerses Balients, does not match with any other accounts by any other historians of the time period, and was simply written as Armenian propaganda of the time. However, Claude Mutafian, in Le Royaume Arménien de Cilicie, suggests that it may have been on this occasion that Hethum remitted his amber scepter to the Armenian convent of Saint James of Jerusalem. "The king of Armenia, back from his raid against the Sultan, went to Jerusalem. He found that all the enemies had been put to flight or exterminated by the
