The Byzantine Empire

Grade 6 · Social Studies · Study Guide

Discover how the Eastern Roman Empire survived for 1,000 years after Rome's fall and preserved ancient knowledge.

When the Western Roman Empire fell in 476 CE, the eastern half kept going — and it kept going for nearly another thousand years. This Eastern Roman Empire is what historians call the Byzantine Empire, named after Byzantium, the ancient Greek city where its capital Constantinople was built. Emperor Constantine had moved the Roman capital to this location in 330 CE, renaming it Constantinople (modern-day Istanbul, Turkey).

The Byzantine Empire was a powerful blend of Roman law and government, Greek language and culture, and Christian faith. Emperor Justinian I, who ruled from 527–565 CE, is one of the most important Byzantine rulers. He reconquered much of the old Western Roman territory, built the stunning Hagia Sophia church (still standing today), and created the Justinian Code — a comprehensive set of laws that became the foundation of legal systems across Europe.

Constantinople sat at the crossroads of Europe and Asia, making it a hub of trade, culture, and diplomacy. Byzantine merchants traded silk, spices, gold, and grain with civilizations from China to the Vikings. The city was protected by massive walls — the Theodosian Walls — that successfully repelled dozens of sieges over centuries.

Byzantine scholars preserved thousands of ancient Greek and Roman texts that might otherwise have been lost, later sparking the Renaissance in Europe. The empire finally fell in 1453 CE when the Ottoman Turks, led by Sultan Mehmed II, conquered Constantinople after a 53-day siege. Byzantine influence survived in Orthodox Christian traditions, Eastern European laws, and the preserved classical texts that shaped the modern world.

Fun facts

• Byzantine 'Greek fire' was a secret weapon — a flammable liquid that burned even on water. It helped the navy defend Constantinople repeatedly, and its exact formula has never been fully figured out.
• The Hagia Sophia's dome appears to float because it sits on a ring of 40 windows that flood the base with light — an engineering trick that baffled visitors for centuries.
