Fall of Constantinople
Sultan Mehmed II captures Constantinople, ending the Byzantine Empire and beginning Ottoman rule over the Greek heartland.
After a 53-day siege, Ottoman forces breached the Theodosian Walls. Emperor Constantine XI died in battle. Mehmed II entered Hagia Sophia and made the city his capital, renaming it Konstantiniyye. The event marked the beginning of nearly four centuries of Ottoman rule over most Greek lands.
