The Byzantine Empire emerged from the eastern half of the Roman Empire, preserving Roman traditions while developing unique characteristics. As the Western Roman Empire fell, Byzantium became a distinct entity, blending Roman, Greek, and Eastern influences into a powerful civilization lasting nearly a millennium.

Byzantium differed from Western Europe in key ways. It maintained a centralized imperial system and sophisticated bureaucracy, while the West became feudal. The Orthodox Church diverged from Roman Catholicism, and Byzantine culture preserved classical learning lost in the West during the Early Middle Ages.
