Constantinople Recaptured: The Byzantine Empire Returns After 57 Years

The gate was left open. Just one gate, the Selymbria portal, on July 25, 1261. Alexios Strategopoulos had marched 800 soldiers toward Constantinople for reconnaissance—nothing more—when his scouts found Latin defenders celebrating outside the walls. Gone. He walked in. Fifty-seven years of Latin rule ended because someone forgot to lock a door. Michael VIII Palaiologos reclaimed his throne without a siege, and the Byzantine Empire breathed for another 192 years. The greatest reconquest in medieval history happened because of a party and an unlocked gate.
