Frederick de la Roche

Frederick de la Roche (died 30 October 1174) was the sixth Latin archbishop of Tyre (1164–1174), chancellor of the kingdom of Jerusalem (c. 1150), and the chief diplomat of King Amalric I. He was a Lorrainer, from the town of La Roche, of noble stock.

Frederick was a canon regular of the Templum Domini in Jerusalem, and was appointed Bishop of Acre and chancellor of Jerusalem around 1150. He participated in the Siege of Ascalon in 1153, and in 1154 King Baldwin III sent him to Antioch to mediate in the dispute between Raynald of Châtillon and the Latin Patriarch. The Patriarch returned to Jerusalem with Frederick. In 1155 Frederick accompanied the Latin Patriarch of Jerusalem to Rome to complain to Pope Hadrian IV about the conduct of various abbeys and churches of Jerusalem, which had been neglecting to recognize the authority of the Patriarch.

When Amalric of Nesle was elected Patriarch of Jerusalem in 1157, he was opposed by Hernesius, Archbishop of Caesarea and Bishop Ralph of Bethlehem, but Frederick supported him and returned to Rome to appeal to Hadrian IV. Frederick won Hadrian's blessing for the new Patriarch, "by the use of lavish gifts, it is claimed", as William of Tyre explains.
