How did the Ottomans manage to conquer Constantinople in 1453?

The Ottomans conquered Constantinople in 1453 through a well-planned siege led by Sultan Mehmed II, utilising superior military technology and tactics.

The fall of Constantinople in 1453 marked the end of the Byzantine Empire and the rise of the Ottoman Empire. The siege was led by the 21-year-old Sultan Mehmed II, who was determined to capture the city that had resisted Ottoman advances for decades. The Ottomans had a significant advantage in terms of numbers, with an estimated 80,000 to 200,000 troops against a defending force of about 7,000 to 12,000.

Mehmed II's strategy was comprehensive and innovative. He commissioned the construction of a fortress, Rumeli Hisarı, on the European side of the Bosphorus Strait, effectively cutting off the city's sea routes and preventing any aid from reaching Constantinople. This was a significant move as the city had previously relied on its natural defences and naval superiority to withstand sieges.

The Ottomans also had a technological edge. Mehmed II employed a Hungarian engineer, Orban, to build a massive cannon, the Basilica, which could fire a 600-pound stone ball over a mile. This was a game-changer in the siege warfare of the time, as the Byzantine walls, previously thought impregnable, were unable to withstand the bombardment.

The siege lasted for 53 days, with the Ottomans launching continuous attacks on the city walls. The defenders, led by Emperor Constantine XI Palaiologos, put up a valiant fight but were vastly outnumbered and outgunned. On 29 May 1453, the Ottomans finally breached the walls of Constantinople, marking the end of the Byzantine Empire.

The fall of Constantinople had profound implications for world history. It marked the end of the Middle Ages and the beginning of the Renaissance, as many Greek scholars fled to Italy, bringing with them ancient texts and knowledge that sparked a cultural revival. It also shifted the balance of power in the region, with the Ottomans emerging as a dominant force in the Mediterranean and beyond.
