Sibylla of Armenia

Sibylla of Armenia was the princess of Antioch and countess of Tripoli by marriage to Bohemond VI from 1254 to 1275, and then regent of the County of Tripoli until their son, Bohemond VII, came of age in 1277. She was closely allied with the bishop of Tortosa, Bartholomew Mansel, which frustrated the scheme to install her as ruler of Tripoli instead of her daughter Lucia after Bohemond VII's death in 1287. During her lifetime, both the principality and the county were lost to the Egyptian Mamluks.
