Leo II of Armenia

Leo II (c. 1236–1289), eldest son of Hethum I and Isabella, ruled Cilician Armenia from 1269 to 1289. In 1266 he fought the Mamluks at the Battle of Mari, where his brother Thoros was killed and Leo captured; Sis was sacked. His father later ransomed him, and Leo took the throne when Hethum abdicated in 1269.

He fostered Italian and Catalan trade and upheld the Mongol alliance, but defeat with the Mongols at Homs in 1281 forced a ten-year truce and territorial concessions in 1285. He died of arsenic poisoning in 1289 and was succeeded by his son Hethum II.
