Raymond-Roupen (also Raymond-Rupen and Ruben-Raymond; 1198 – 1219 or 1221/1222) was a member of the House of Poitiers who claimed the thrones of the Principality of Antioch and Armenian Kingdom of Cilicia.
He then pursued his claim to Cilicia, which Leo had unexpectedly willed to his daughter Isabella on his deathbed, but was defeated and imprisoned until death.
[4][5] The infant was heir apparent to his grandfather Bohemond III of Antioch by primogeniture,[2] but this principle was not upheld in the Latin East.
[6] Leo, who had no sons, recognized Raymond-Roupen as his heir presumptive, and made it his principal mission to secure his grandnephew's succession to Antioch as well.
[5] Conrad of Wittelsbach traveled from Sis to Antioch, where he compelled Bohemond III to summon his vassals and have Raymond-Roupen recognized as his heir apparent.
[13] Raymond-Roupen found new allies in the Hospitallers and Antiochene noblemen, including the leader of the commune, by promising grants of land.
[14] Raymond-Roupen was consecrated as Prince of Antioch by the Latin Patriarch, Peter of Ivrea, and received the submission of the nobility and the commune.
[13][17] Prince Bohemond IV's restoration, followed by King Leo I's death in May 1219, thus ended Raymond-Roupen's prospects of ruling Antioch.
[13] Raymond-Roupen instead rose to claim Cilicia, as did John of Brienne, husband of Leo's elder daughter, Stephanie.
[17] Pope Honorius III ruled that Stephanie or her son by John should succeed King Leo,[16] but both mother and child died soon after.
[19] Honorius and Pelagius decided not to put forward the claims of Raymond-Roupen's young daughters, Maria and Eschiva, who were taken by their mother to Cyprus.
