Byzantine Empire (Second Rome)
The eastern continuation of the Roman Empire from Constantine's founding of Constantinople in 330 CE to its fall to the Ottoman Turks in 1453 CE, a Greek-speaking Christian bureaucracy that preserved Roman legal traditions, Hellenistic culture, and Orthodox Christianity for over a thousand years while Western Europe fragmented.
Constantine moved the Roman capital east to Constantinople (modern Istanbul) in 330 CE, building a new city on the site of the Greek colony Byzantium at the strategic junction of Europe and Asia. The move was not merely administrative, it reflected where the empire's wealth actually was. The eastern provinces (Egypt, Syria, Anatolia, Greece) produced far more revenue than the increasingly barbarian-pressured West. Constantine was moving the capital to the money.
What the Byzantines called their empire was simply 'Romania', they did not think of themselves as a different civilization from Rome. But the differences were real. Where Rome had been Latin and pagan, Constantinople was Greek and Christian from the start. The Justinian Code (529–534 CE) systematized Roman law into a form that survived to influence modern European legal systems. The Greek Orthodox Church, under the Patriarch of Constantinople, maintained a different relationship with the emperor than Rome's pope, the emperor was supreme in church matters (Caesaropapism), not the patriarch.
The Byzantine Empire was the cultural and commercial hinge of the medieval world for centuries. In 1054 CE, the Great Schism permanently divided Eastern Orthodoxy from Roman Catholicism, a split still unhealed. In 1453 CE, Ottoman Sultan Mehmed II conquered Constantinople, ending the last direct institutional continuity with ancient Rome. Many Byzantine scholars fled to Italy, bringing Greek manuscripts that helped spark the Renaissance.
Predictive History frames Byzantium as the counterexample to the Western Roman collapse narrative: a bureaucratically complex, religiously organized empire can maintain continuity across a millennium when it controls strategic geography and a productive agricultural base.

Frequently asked questions
Why did Constantine move Rome's capital to Constantinople? +
Constantine moved the capital east in 330 CE because the empire's wealth was in the east, Egypt, Syria, Anatolia, and Greece generated far more revenue than Western Europe, which was already under pressure from Germanic migrations. Constantinople's position at the junction of Europe and Asia also gave superior strategic control of trade routes.
How did the Byzantine Empire end? +
Ottoman Sultan Mehmed II conquered Constantinople on May 29, 1453 CE after a 53-day siege, ending 1,123 years of continuous Roman institutional succession. The fall marked the final end of ancient Rome's political legacy. Many Byzantine scholars fled to Italy with Greek manuscripts, and their knowledge is credited as a significant catalyst for the Italian Renaissance.
