"Leo IV or Leon IV (Armenian: Լեւոն Դ, Levon IV) (also numbered Leo V; ) (1309 – August 28, 1341) was the last Hethumid king of Cilicia, ruling from 1320 until his death. He was the son of Oshin of Armenia and Isabel of Korikos, and came to the throne on the death of his father. His name is sometimes spelled as Leo or Leon.
He spent his minority under the regency of Oshin of Korikos. During this period, the kingdom was much harassed by Mamluks and Mongols. In 1320, the Egyptian sultan Naser Mohammed ibn Kelaoun invaded and ravaged Christian Armenian Cilicia. In a letter dated July 1, 1322, and sent from Avignon, Pope John XXII reminded Mongol ruler Abu Sa'id Bahadur Khan of the alliance of his ancestors with Christians, asking him to intervene in Cilicia. At the same time he advocated that he abandon Islam in favor of Christianity. Mongol troops were sent to Cilicia, but only arrived after a ceasefire had been negotiated for 15 years between Constantin, patriarch of the Armenians, and the sultan of Egypt." - (en.wikipedia.org 29.01.2022)
