Fall of Constantinople

1453 Ottoman conquest of the Byzantine capital

Constantinople, the capital city of the Byzantine Empire, was captured by the Ottoman Empire on 29 May 1453 as part of the culmination of a 53-day siege which had begun on 6 April. The attacking Ottoman Army, which significantly outnumbered Constantinople's defenders, was commanded by Sultan Mehmed II (later nicknamed "the Conqueror"), while the Byzantine army was led by Emperor Constantine XI Palaiologos. After conquering the city, Mehmed II made Constantinople the new Ottoman capital, replacing Adrianople.
