The See of Tyre was the most prestigious archbishopric under the authority of the patriarchs of Antioch from the 5th century.
[1] The archbishops had more than a dozen suffragans, including the bishops of Acre, Beirut, Byblos, Sidon, Tripoli and Tortosa.
[4] Documents written in the early 12th century did not refer to the bishops of the three dioceses, suggesting that the three sees, all located in the newly established crusader County of Tripoli, were actually left vacant.
[7] Accepting the king's argumentation, the Pope ruled on 8 June 1111 that the boundaries of the ecclesiastical provinces should follow the political frontiers.
[9] Gormond of Picquigny signed a treaty with the Venetians about the joint conquest of Tyre on behalf of Baldwin II of Jerusalem in December 1123.
