The Fall of Constantinople occurred on May 29, 1453, marking the end of the Byzantine Empire. The city, known for its strong walls and strategic location, was besieged by the forces of the Ottoman Empire, led by Sultan Mehmed II. After a lengthy siege, the Ottomans breached the walls, leading to the capture of the city. This event significantly changed the course of history, as it allowed the Ottomans to expand their territory in Europe and solidify their power. The fall also prompted many scholars to flee to the West, bringing with them ancient texts and knowledge that contributed to the Renaissance.
