According to the pre-congregation church tradition, this ancient patriarchate was founded by the Apostle Saint Peter. The patriarchal succession was disputed at the time of the Meletian schism in 362 and again after the Council of Chalcedon in 451, when there were rival Melkite and non-Chalcedonian claimants to the see. After a 7th-century succession dispute in the Melkite church, the Maronites began appointing a Maronite patriarch as well. After the First Crusade, the Catholic Church began appointing a Latin Rite patriarch of Antioch, though this became strictly titular after the Fall of Antioch in 1268, and was abolished completely in 1964. In the 18th century, succession disputes in the Greek Orthodox and Syriac Orthodox Churches of Antioch led to factions of those churches entering into communion with Rome under claimants to the patriarchate: the Melkite Greek Catholic patriarch of Antioch and the Syriac Catholic patriarch of Antioch, respectively. Their Orthodox counterparts are the Syriac Orthodox patriarch of Antioch, the Greek Orthodox patriarch of Antioch, respectively.
