Description

The fall of the Western Roman Empire in 476 CE marked the end of Western imperial continuity, with Odoacer deposing the last Western emperor Romulus Augustulus. This event led to political fragmentation in Western Europe and the beginning of the medieval period, while the Eastern Roman Empire (Byzantine) continued for another millennium.

Significance

• Political Fragmentation: Beginning of medieval period in Western Europe
• Periodization Marker: Key threshold marking end of Antiquity, beginning of Middle Ages
• Civilizational Transformation: Western Europe enters new period
• Eastern Continuity: Byzantine Empire continues (Eastern Roman Empire)
