#55: 1453: The Holy War for Constantinople and the Clash of Islam and the West

For over a thousand years, Constantinople stood as "the city" — the last living capital of the Roman Empire, the wealthiest and most fortified place on earth. On 29 May 1453, after a 53-day siege, it fell. In this episode of The Prometheans, we sit down with historian Roger Crowley, author of 1453: The Holy War for Constantinople and the Clash of Islam and the West, to walk through one of history's great hinge moments — the siege that ended the Byzantine Empire and reshaped the medieval world.

We trace the story from the unlikely rise of the 21-year-old Sultan Mehmed II, to the courage of the last Roman emperor, Constantine XI, to the engineering feat that decided the war: the overland transport of an entire Ottoman fleet into the Golden Horn. We also dig into the harder questions the book raises — how much this was really a "clash of civilizations" when Christian engineers built the decisive Ottoman cannons, what the Islamic tradition around the conquest actually says and where scholars still debate it, and why Hagia Sophia's transformation in 1453 still echoes in headlines today.

This is history told for an audience that takes both traditions seriously — not a sides-taking exercise, but an attempt to understand a moment that both Christian and Islamic memory have mythologized, and to find the more complicated, more human story underneath.

Guest: Roger Crowley, author of 1453, Empires of the Sea, City of Fortune, and Conquerors.
