Sempad of Armenia
Sempad (1277 – c. 1310), a son of Leo II of Armenia, usurped the Cilician throne in 1296 while his brothers Hethum II and Thoros escorted their sister to Constantinople. In 1297 he won Mongol recognition and a Mongol bride at the Ilkhan Ghazan's court.
Sempad had the returning Hethum partially blinded and imprisoned at Partzerpert, where Thoros was strangled on his orders in July 1298. Their brother Constantine then freed Hethum, who overthrew Sempad. After another plot with Constantine, Sempad was imprisoned for life, dying around 1310.
