Constantine of Barbaron now thought it wise to reconcile Armenia with the Papacy: loyal messengers were sent in the name of the young couple to the Pope and to the Emperor Frederick II. Although Bohemond IV and later his son, Bohemond V attempted to persuade the Pope to arrange a divorce between Isabella and Hethum, but both he and King Henry I of Cyprus were specifically forbidden by Rome to attack the Armenians. The marriage was legalized by Rome in 1237.
