Answer:
The byzantine empire fell
Step-by-step explanation:
The conquest of Constantinople refers to the 55 days siege of the massive walls of Constantinople across land and sea by the Ottoman Turks led by Sultan Mehmed II of the Ottoman Empire.
Eventually, the great walls of Constantinople collapsed under a constant barrage of canons leading to the fall of the great Constantinople on May 29, 1453.
The fall of Constantinople marked the end of the Byzantine empire. The Turks changed the name of Constantinople to Istanbul and made Constantinople the capital of the Ottoman Empire.
