Ivan III's Moscow Kremlin

Timeline

1. 1462Moscow Kremlin · MoscowIn 1462 Ivan III succeeded Vasily II as Grand Prince of Moscow, and the Kremlin became the seat of the supreme power of all Rus'. In the early years of his reign he handled diplomacy and internal affairs with Novgorod, the Tatar khanates, and Lithuania here; though the castle was still mainly of mixed wood-and-stone construction, it already served as the core venue for the grand prince's court, senior churchmen, and noble assemblies.
2. c. 1463–1470Moscow Kremlin · MoscowIn the mid-to-late 1460s Ivan III directed wars of annexation against Novgorod and other regions from the Kremlin, which became the hub for conscription, rewards, and diplomatic negotiations. Religious buildings such as the Assumption Cathedral already carried symbolic weight, tightly binding grand-princely power and Orthodox authority within the castle and providing a spatial vehicle for the later 'Third Rome' ideology.
3. 1472–1495Moscow Kremlin · MoscowIn 1472 Ivan III married Sophia Palaiologina, a descendant of the last Byzantine emperors; the court adopted the double-headed eagle and more elaborate imperial ritual. Italian architects were then invited to plan the work, and between 1485 and 1495 red-brick walls and towers replaced the old wooden palisade, forming the prototype of today's Kremlin defensive outline and marking Moscow's transformation from a principality capital to an imperial capital.
