Baldwin III of Jerusalem
In 1160, Maria's stepfather Raynald of Châtillon was taken prisoner by Maj al-Dīn, the ruler of Aleppo and an ally of Nūr al-Dīn. Her mother claimed the Principality of Antioch for herself, but the nobles supported her son, Maria's brother Bohemund III. King Baldwin III of Jerusalem set Bohemund III up as prince and appointed as regent the rich and worldly Aimery of Limoges, Latin Patriarch of Antioch and an old opponent of Raynald. Constance protested this decision in Constantinople at the court of the Byzantine emperor Manuel I Komnenos, the nominal overlord of Antioch.
