[citation needed] Two years later a great disagreement took place between the King and Catholicos on the topic of union with the Roman Catholic Church, which grew to the point where the king convened a meeting of the clergy which deposed Constantine.
[citation needed] Almost two decades later, upon the death of Gregory VII of Cilicia, a meeting was called by King Levon III to discuss new church regulations proposed by the recently deceased Catholicos.
Towards the end of his second reign the Mamlukes, with their allies the Turks, marched into Cilicia and laid siege to the region.
Constantine wrote to Pope John XXII for aid, to which he responded with consolation and some money.
Scythian troops were sent to protect Cilicia but before they arrived the region was invaded again and much of the Armenian army was killed fighting them.
