At one point, there was at least nominally a "sixth" claimant to the Patriarchate. When the Western European Crusaders established the Principality of Antioch, they established a Latin Rite church in the city, whose head took the title of Patriarch. After the Crusaders were expelled by the Mamelukes in 1268, the pope continued to appoint a titular Latin patriarch of Antioch, whose actual seat was the Basilica di Santa Maria Maggiore in Rome. The last holder of this office was Roberto Vicentini, who died without a successor in 1953. The post itself was abolished in 1964.
