The Latin Patriarch of Antioch was an office established in the aftermath of the First Crusade by Bohemund, the first Prince of Antioch. The city already had a Greek Patriarch, who was expelled and fled to Constantinople. The Byzantine Empire was greatly offended by this and worked towards re-establishing either a joint patriarchate or a single Greek patriarchate; the terms of the Treaty of Devol in 1108 nominally restored a Greek patriarch, although this was never enforced.
Under Manuel I Comnenus there was briefly a joint patriarchate when Antioch fell under Byzantine control, but for the most part there was only a Latin patriarch, up until the principality was recaptured by the Mamluks in 1268. A Greek patriarch continued to be appointed in Constantinople throughout this period.
This titular office maintained itself until it was finally abolished in 1964.
From that time Antioch had its Latinpatriarchs, until in 1268 Christian, the last incumbent, was put to death by the Sultan Bibars, during the conquest of the city.
The title of LatinPatriarch of Antioch is yet conferred; but the recipient resides in Rome and is a member of the chapter of the basilica of St. Mary Major.
In that of 344 the Arian bishop, Stephen of Antioch, was deposed for misconduct.
