Ибн аль-Асир
Manuel I Komnenos died on 24 September 1180. Bohemond soon repudiated his wife, Theodora, to marry an Antiochene lady of bad reputation, Sibylla. Ali ibn al-Athir described her as a spy who was "in correspondence with Saladin and exchanged gifts with him". Patriarch Aimery accused Bohemond of adultery and excommunicated him. After Bohemond confiscated church property, Aimery imposed an interdict on Antioch and fled to his fortress at Qosair. Bohemond besieged the fortress, but Reynald Masoir, Lord of Margat, and other noblemen who supported the patriarch rose up against him.
