Baldwin IV of Jerusalem
Around 1181, Bohemond left his wife Theodora, a niece of the recently deceased Emperor Manuel, and married a woman named Sibylla, "who had the reputation of practicing evil arts" according to William of Tyre. He was excommunicated by Pope Alexander III, and Antioch was placed under an interdict. He imprisoned Aimery and other bishops and looted their churches. Aimery, supported by the nobility of Antioch under their leader, , lord of Margat, held out in al-Quṣayr under siege by Bohemond. Aimery himself took part in the fighting and even instigating rioting against Bohemond's rule. Baldwin IV of Jerusalem intervened by sending Patriarch Eraclius of Jerusalem to Laodicea to negotiate with both parties. Bohemond remained excommunicate so long as he kept Sibylla, and Aimery's church property was returned, but the interdict on Antioch was lifted.
