Amalric I of Jerusalem
In 1164, Bohemond was captured by Nureddin at the Battle of Harim. Aimery assumed the regency of the principality and immediately sent a letter to Louis VII of France requesting military aid. The rule of the patriarch was brief. Bohemond was freed, for a ransom of 150,000 dinars, in 1165 through the intervention of Manuel and Amalric I of Jerusalem. Upon his release Bohemond visited Manuel and agreed to re-establish a Greek Patriarch in Antioch, Athanasius I. Aimery protested this and imposed an interdict on the city. He remained in exile at his castle of al-Quṣayr ("Xusayr") until the death of Athanasius in 1170 in an earthquake that destroyed the cathedral during the liturgy. By 1180 the Byzantine emperor was treating Aimery as the legitimate patriarch, and it is not unlikely that William of Tyre in some negotiations at Antioch and then Constantinople on behalf of Amalric of Jerusalem had reconciled them.
