Moscow, Third Rome

Moscow, Third Rome (Russian: Москва — третий Рим, romanized: Moskva — tretiy Rim) is a theological and political concept asserting that Moscow is the successor to Rome and Constantinople as the center of Orthodox Christianity. The idea emerged in the late 15th and early 16th centuries after the Fall of Constantinople (1453), receiving its classic formulation in the epistles of the monk Philotheus of Pskov, who stated that "two Romes have fallen, the third stands, and there will be no fourth." Originally eschatological, the doctrine framed the Grand Prince of Moscow not as a conqueror, but as the final sovereign protector of pure Orthodoxy before the Second Coming. During the 19th century, Slavophile and Pan-Slavist thinkers transformed this pastoral idea into an imperial ideology justifying state expansion and primacy over the Orthodox world. In the 21st century, the concept has been revived in Russian state and church discourse alongside the doctrine of the "Russian world."
