1453 AD
On May 29, 1453, the Ottoman Turks under the 21-year-old Sultan Mehmed II breached the walls of Constantinople, ending the Byzantine (Eastern Roman) Empire after nearly 1,123 years. The last emperor, Constantine XI Palaiologos, removed his imperial insignia and led a final charge against the Turkish forces, disappearing into the battleβlegend says he was transformed into a marble statue and will one day return to liberate the city.
The fall of Constantinople was a catastrophe for Christendom. The great Hagia Sophia, the masterpiece of Christian architecture, was converted into a mosque. Hundreds of thousands of Greek Orthodox Christians fled westward, bringing with them the treasures of classical learning that would help spark the Renaissance in Italy. The Pope called for a crusade, but Europe was too divided to respond.
The Ottoman conquest opened the door for centuries of Turkish expansion into Europe, culminating in the siege of Vienna in 1529 and again in 1683. The fall of Constantinople also cut off European access to the eastern trade routes, indirectly prompting the Age of Exploration.
