The Byzantine Empire was a continuation of the Roman Empire in the eastern Mediterranean, lasting from approximately 330 AD to 1453 AD. Its capital was Constantinople, a city founded by Emperor Constantine the Great. The empire was known for its rich culture, advanced administration, and significant contributions to art, architecture, and law, particularly through the Code of Justinian. The Byzantine Empire played a crucial role in preserving ancient Greek and Roman knowledge during the Middle Ages. It was a center of trade and diplomacy, connecting Europe and Asia. The empire faced numerous challenges, including invasions and internal strife, ultimately falling to the Ottoman Turks in 1453.
