About Constantine I, King of Armenia
- Constantine I (Armenian: ????????? ?, Western Armenian transliteration: Gosdantin or Kostantine;) (also called Constantine III; 1278 – c.
- 1310) was briefly king of the Armenian Kingdom of Cilicia from 1298 to 1299.
- He was the son of Leo II of Armenia and Kyranna de Lampron and was part of the Hetoumid-family. He helped his brother Sempad to usurp the throne in 1296, but turned against him two years later in 1298 to restore his older brother Hethum II.
- He assumed the throne for a year while Hethum recovered from his imprisonment.
- Shortly after Hethum's resumption in 1299, Constantine plotted to restore Sempad again, and both were imprisoned for the rest of their lives.
