In January 1454 Sultan Mehmet II (1451–81), ruler of much of the Orthodox Christian Balkans and lately conqueror of Byzantium, vested the patriarch of Constantinople, George Scholarius, with full ecclesiastical authority over all the Orthodox Christians in the Ottoman empire.
This ‘donation’ of Mehmet, long accepted by the scholarly consensus, now stands revealed as a ‘foundation myth’, concocted long after 1454 by the Great Church to justify the over-arching authority it wielded or aspired to wield under the Ottoman imperium.
