Constantine III reigned from 1344 to 1362 AD as the monarch of Cilician Armenia (Kilikia), succeeding Constantine II (Guy de Lusignan). A descendant of the Hethumid line through the house of Neghir and the son of the Great Marshal Baldwin, he is remembered by chroniclers as the last powerful king of the Cilician realm. He assumed the throne following a national uprising and immediately sought to stabilize the kingdom by unifying the patriotic nobility. His reign was a period of relentless warfare against the Mamluk Sultanate and the Turkoman tribes. While he achieved notable victories, such as the liberation of the fortress of Kapan and the port of Ayas, the kingdom ultimately suffered the loss of Adana and Tarsus in 1359 AD. Domestically, he is distinguished for his decisive break with the Roman Catholic Church at the Council of Sis in 1361 AD, where he officially cancelled all previous union agreements and condemned the Papacy’s failure to provide aid.

Constantine III reigned between 1344 and 1362 AD, coming to power after the violent deposition of the first Lusignan monarch. As the son of Baldwin, Lord of Neghir, his ascension represented a return to native Armenian leadership after a period of intense cultural alienation. To secure his position, he attempted to eliminate rival claimants from the previous dynasty, though his targets—the nephews of Constantine II—successfully escaped to Cyprus. Despite these internal struggles, Constantine III was able to consolidate the "patriotic princes" of the highlands, leading a resurgence that temporarily restored the military prestige of the Kingdom of Cilicia (Kilikia).

War Against the Mamluk and Turkoman Hordes

The middle years of Constantine III’s reign were defined by a three-front struggle against the Egyptian Sultanate, the Emirate of Aleppo, and the Turkomans of Iconium. In 1346 AD, he successfully repelled a massive invasion and liberated the strategic fortress of Kapan. By the autumn of 1347 AD, with the support of the Cypriot fleet, he defeated the Egyptian vanguard and recaptured the vital port of Ayas. Utilizing a period of internal succession strife in Egypt between 1348 and 1349 AD, Constantine III allied with the Knights Hospitaller to crush the raiding forces of the Emir of Aleppo, successfully pushing the Armenian frontiers as far as the Gulf of Alexandretta. However, the relentless pressure from the East eventually forced a retreat, resulting in the loss of Tarsus and Adana by 1359 AD.

The Council of Sis and the Break with Rome

The final chapter of Constantine III’s rule was marked by a profound shift in religious and foreign policy. Disillusioned by the hollow promises of military support from the Papacy and Western powers, the king and Catholicos Mesrop I Artazetsi convened a national assembly in 1361 AD. Known as the Council of Sis, this gathering formally abolished all decisions of previous councils regarding the union between the Armenian and Catholic churches. By condemning the behavior of the Papacy and reclaiming the traditional autonomy of the Armenian faith, Constantine III sought to restore national unity even as the kingdom’s borders continued to shrink. He died of natural causes in 1362 AD, leaving behind gold coins minted in his name and a legacy as the last sovereign who attempted to defend the highlands through local resolve rather than foreign mirages.

The legacy of Constantine V endures through the centuries — a testament to the enduring spirit of the Armenian people and their unbroken pursuit of sovereignty, culture, and faith.
