Latin Patriarchate of Constantinople

The Latin Patriarch of Constantinople was an office established as a result of Crusader activity in the Near East. The title should not be confused with that of the Eastern Orthodox Patriarchate of Constantinople, an office which existed before and after. Before the East–West Schism in 1054, the Christian Church within the borders of the ancient Roman Empire was effectively ruled by five patriarchs (the "Pentarchy"): the Bishop of Rome (who rarely used the title "Patriarch") and those of Constantinople, Jerusalem, Alexandria, and Antioch.
