Since 1247,
Cilician Armenia itself had been a vassal state of the Mongol Empire, from an agreement made by Hethum II's grandfather,
Hethum I. 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 European
Crusaders and
Byzantine Empire, aggression from the Turkish
Karamanids to the west and the Turkish
Sultanate of Rum to the north, a vassal relationship with the aggressive
Mongol Empire in the east, and defending itself from attacks from the south, from the Muslim
Mamluk Sultanate out of Egypt. The Crusades had lost European support and were winding down, and Islamic forces were sweeping northwards from
Mamluk Egypt, re-taking land which had earlier been lost to the Crusaders and Mongols, and pushing back against the Mongol advance. In 1289,
Angelo da Clareno and a few other
Spiritual Franciscans arrived to
missionize among the
Armenian Christians. They had been repeatedly jailed in Italy for their strong condemnations of luxury in the church but they won favor at the Armenian court.
St Thomas of Tolentino was sent by Hethum to Rome, Paris, and London to advocate another crusade to support the Armenians; he failed in this, but returned with additional clerics to support the mission and advocate the reunification of the
Armenian Church with
Rome. In 1292,
Cilician Armenia was invaded by
Khalil, the
Mamluk sultan of
Egypt. His father the Mamluk sultan
Qalawun had earlier broken the treaty of 1285, was marching North through Palestine with his troops, and also demanded the surrender of the Armenian cities of
Marash and
Behesni. Qalawun died before the campaign was completed, but Khalil continued his father's advance northwards, and had conquered the
Kingdom of Jerusalem in 1291 at the
Siege of Acre. Khalil's forces continued on from there, sacking the Armenian city of
Hromgla, which was defended by Hethum's uncle, Raymond, but fell after a siege of 33 days. 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. He did stay active in the politics of the kingdom though, and negotiated with the Egyptian leader
Ketbougha for the return of the prisoners who had been taken at Hromgla, as well as for some church relics which had been pillaged. ==Second reign==
