Christianity in Turkey
Constantinople became established in the ecclesiastical hierarchy at the Council of Constantinople in 381. Second only to Rome, the legendary origins of the Patriarchate of Constantinople go back to St. Andrew, Metrophanes and Alexander of Constantinople. Constantinople's primacy over the Patriarchates of Alexandria and Antioch was reaffirmed at the Council of Chalcedon in 481, after which the papacy in Rome supported Constantinople in its dispute with Alexandria over monophysitism. Later, when Rome sought to assert its primacy over Byzantium, the Eastern Orthodox church developed the doctrine of pentarchy as a response.
History of architecture
The Byzantine Empire gradually emerged as a distinct artistic and cultural entity from the Roman Empire after AD 330, when the Roman Emperor Constantine moved the capital of the Roman Empire east from Rome to Byzantium (later renamed Constantinople and now called Istanbul). The empire endured for more than a millennium, dramatically influencing Medieval and Renaissance-era architecture in Europe and, following the capture of Constantinople by the Ottoman Turks in 1453, leading directly to the architecture of the Ottoman Empire.
