Latin Patriarchate of Constantinople

The Latin Patriarchate of Constantinople is a diplomatic and ecclesiastical jurisdiction of the Roman Catholic Church, established in the 13th century, representing Catholics in the region historically known as Byzantium. Although its significance has diminished over time, it serves as a symbolic presence of Western Catholic tradition in predominantly Eastern Orthodox areas. Today, it functions mainly as a titular title without a large, active congregation, maintaining historical ties and fostering dialogue between different Christian communities in Istanbul and the broader region.
