Before the arrival of the crusaders to Syria in the late 11th century, the Orthodox bishops of Sidon had been suffragans of the
archbishops of Tyre, who were in turn subject to the authority of the
Orthodox patriarchs of Antioch. The first crusader
king of Jerusalem,
Baldwin I captured Sidon with the assistance of Venetian and Norwegian fleets on 5 December 1110. He wanted to ensure that all sees in his kingdom were subject to the
Latin patriarchs of Jerusalem. He and
Ghibbelin of Arles, Latin patriarch of Jerusalem, asked
Pope Paschal II to authorize the expansion of the jurisdiction of the see of Jerusalem to include the diocese of Sidon. The Pope accepted their proposal and declared in 1111 that the boundaries of the ecclesiastic provinces should follow the political borders, making Sidon subject to Jerusalem. However, the
patriarchs of Antioch,
Bernard of Valence, lodged an objection with the Holy See and prevented the appointment of a bishop subject to Jerusalem at Sidon.
Philip of Novara describes an unnamed bishop of Sidon as an envoy of
Frederick II during the
War of the Lombards around 1231. From the 14th-century, the Sidon became a
titular see. == Bishops ==
