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.
Early life
Sibylla was the daughter of Queen Isabella and King Hethoum I of Armenia. In 1254, at the suggestion of the crusader King Louis IX of France, Sibylla was married to Bohemond VI, the prince of Antioch and count of Tripoli. Their children were Bohemond VII, Lucia, and Maria.The Principality of Antioch fell to the Egyptian Mamluks in 1268.
Regent of Tripoli
Sibylla's husband, Bohemond VI, died in 1275, and their son, Bohemond VII, inherited the County of Tripoli. Since Bohemond VII was then a minor, Sibylla assumed government in his name as regent. She was challenged by King Hugh III of Cyprus, who claimed regency as the closest adult in the line of succession. But family custom and popular opinion was on the princess's side. She sent her son to the court of her brother King Leo II and appointed the bishop of Tortosa, Bartholomew Mansel, as her bailli. Hugh thus found no support.Sibylla's husband, Bohemond VI, and Roman mother-in-law, Lucia of Segni, had installed Romans in important government posts, incurring displeasure of the local nobility. The nobility thus supported Sibylla and Bartholomew when they dealt with the Romans through executions and banishments. They failed to remove Paul of Segni, who was Bohemond VI's uncle and bishop of Tripoli, due to his friendship with the Knights Templar. The Templars were thus hostile to Bohemond VII when he returned from Armenia to assume government in 1277.
