The City That Conquered Three Empires

The City That Conquered Three Empires In 657 BC, Greek colonists founded Byzantion on a peninsula between Europe and Asia. Constantine transformed it into Constantinople in 330 AD, capital of the Roman Empire. Justinian built Hagia Sophia and reconquered the West, but Arab sieges and the Plague of Justinian shattered his dream. The Fourth Crusade sacked Constantinople in 1204, breaking Byzantine power forever. On May 29, 1453, Sultan Mehmed II conquered the city, ending the Roman Empire after two thousand years. Renamed Istanbul, it became the Ottoman capital and remains Europe's largest city, a metropolis that refused to choose between continents, empires, or eras.
