Byzantine Empire

The Eastern Roman Empire, known to historians as the Byzantine Empire, survived the fall of Rome by nearly a thousand years. Centred on Constantinople, it preserved Roman law, Greek culture, and Orthodox Christianity across the medieval period. By the 15th century it had been reduced to the city of Constantinople and a few Aegean islands. On 29 May 1453 Sultan Mehmed II's Ottoman forces breached the Theodosian Walls; Emperor Constantine XI died in the final assault, ending 1,058 years of continuous Roman imperial succession.
