In 1453, which important city fell?

In 1453, the important city that fell was Constantinople. It was captured by the Ottoman Turks, led by Sultan Mehmed II, after a lengthy siege. This event is considered significant because it marked the end of the Byzantine Empire and the beginning of Ottoman domination in the region. Constantinople's fall had wide-ranging consequences, as it disrupted trade routes, led to the dispersal of Greek scholars and their knowledge, and inspired European powers to seek alternative routes to Asia, eventually leading to the Age of Exploration.
