Why Nobody Could Conquer Constantinople for 1,000 Years

Why was Constantinople almost impossible to conquer for nearly 1,000 years? From its strategic location between Europe and Asia to its legendary defensive walls, the Byzantine capital survived some of the most powerful armies and sieges in history. Founded as Constantinople by Emperor Constantine in 330, the city became the heart of the Eastern Roman Empire. Its massive Theodosian Walls, protected harbors, underground water cisterns, powerful navy, and mysterious weapon known as Greek fire helped repel attacks by Persians, Arabs, Avars, and other enemies. But even the strongest defenses could not guarantee survival forever. Discover how the city resisted repeated sieges, why the Fourth Crusade captured it in 1204, and how Ottoman Sultan Mehmed II finally conquered Constantinople in 1453. Explore the fall of the Byzantine Empire and the transformation of Constantinople into the capital of the Ottoman Empire, later known as Istanbul.
