Which event in 1453 had significant impact on the European world?

The fall of Constantinople in 1453 marked a significant turning point in European history. The Ottoman Empire, led by Sultan Mehmed II, captured the city, effectively ending the Byzantine Empire. This event not only shifted the balance of power in Eastern Europe but also prompted the European Renaissance, as scholars fled to the West, bringing with them classical knowledge and texts. Additionally, it spurred European exploration and the search for new trade routes, ultimately leading to the Age of Discovery.
