A Roman empire in the east
The state modern historians call Byzantine was the eastern Roman Empire. Its inhabitants called themselves Romans, governed from Constantinople and maintained Roman law through Greek-speaking institutions.
Emperors such as Justinian combined military ambition, legal codification and religious authority. The empire lost and regained territory repeatedly, adapting taxation, armies and diplomacy to survive severe crises.
Contraction and recovery
Arab conquests removed wealthy provinces in the seventh century, while warfare reshaped the empire's economy and administration. Later Macedonian emperors oversaw military recovery and cultural production.
The Fourth Crusade captured and looted Constantinople in 1204, creating rival states and lasting damage. Byzantine rulers recovered the city in 1261 but controlled fewer resources and faced powerful neighbours.
Ottoman expansion
Ottoman rulers built a flexible state across Anatolia and the Balkans through conquest, alliances and incorporation of local elites. Their forces surrounded a Byzantine capital increasingly separated from its former hinterland.
Mehmed II prepared carefully for the 1453 siege, constructing a fortress on the Bosporus, assembling artillery and coordinating land and naval forces. Defenders used the formidable walls but lacked the manpower for a prolonged campaign.
The conquest and its meanings
Ottoman troops entered Constantinople on 29 May after a final assault. Emperor Constantine XI died in the fighting, and Mehmed made the city an imperial capital populated by Muslims, Christians and Jews.
The conquest ended a political state but not Greek learning, Orthodox Christianity or Roman legal traditions. Later narratives have treated 1453 as an abrupt civilisational divide; the evidence instead shows both rupture and continuity.
Why It Matters
The story challenges the idea that Rome simply fell in the fifth century and places 1453 within the long transformation of Mediterranean and Eurasian power.
