Leo IV, King of Armenia

Who was Leo IV, King of Armenia?

Leo IV 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, Pope John XXII sent a letter from Avignon to the Mongol ruler Abu Sa'id Bahadur Khan, reminding him 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.

The Regent Oshin had married his stepmother, Jeanne of Anjou, and Leo was forced to marry Oshin's daughter Alice on August 10, 1321.
