Fall of Constantinople
✨ 1453, Constantinople (Byzantine Empire)
The fall of Constantinople took place on May 29, 1453, when the Ottoman army under Sultan Mehmed II captured the capital of the Byzantine Empire. Constantinople had been founded as the new capital of the Roman Empire by Emperor Constantine the Great in 330 and later became the center of the Byzantine state. By the fifteenth century, however, the empire had lost most of its territories and Constantinople was largely surrounded by Ottoman lands.
Emperor Constantine XI Palaiologos defended the city with a relatively small force, supported by soldiers and sailors from several parts of the Christian world. The city's massive defensive walls, especially the Theodosian Walls, had protected it for centuries, but the Ottomans brought large cannons and a powerful army to the siege. The siege began in April 1453 and lasted about seven weeks.
Mehmed II used artillery to bombard the walls and also ordered the construction of fortifications and other measures to prevent assistance from reaching the city. On May 29, Ottoman forces launched their final assault. After intense fighting, they entered Constantinople and overcame the remaining defenders. Emperor Constantine XI died during the battle, although the exact circumstances of his death remain uncertain.
The capture ended the Byzantine Empire, which had survived in some form for more than a thousand years after the division of the Roman Empire. Constantinople became the Ottoman capital and remained so until 1922. The conquest also strengthened Ottoman control over a strategic crossroads between Europe and Asia and had lasting consequences for the political and economic history of the Mediterranean.
