3. The Siege of Constantinople (1453)
In 1453, the once-mighty Byzantine Empire’s capital, Constantinople, fell to the Ottoman Empire after a 53-day siege. Sultan Mehmed II employed superior technology, including massive cannons, to breach the city’s formidable walls. The Ottomans also ingeniously transported ships overland to bypass the chain blocking the Golden Horn, allowing them to attack from multiple fronts. This stunning collapse marked the end of 1,000 years of Eastern Roman rule and symbolized a pivotal, humiliating end for Byzantium (britannica.com).
