The Roman Catholic Diocese of Sidon was a bishopric in the Kingdom of Jerusalem in the 12th and 13th centuries.
[1][2] The first crusader king of Jerusalem, Baldwin I captured Sidon with the assistance of Venetian and Norwegian fleets on 5 December 1110.
[4][5] 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.
[5] 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.
