#498 – Anthony Kaldellis: Roman Empire, Byzantine Empire, Rise & Fall of Empires

Jun 30, 2026

Summary

Lex Fridman interviews historian Anthony Kaldellis, who argues that the Byzantine Empire was simply the continuous Eastern Roman Empire, not a distinct entity. They explore the state’s 2,200-year history, emphasizing that emperors maintained power through a "perpetual referendum" of public consent rather than absolute authority. Kaldellis explains that rulers projected a persona of tireless service to avoid the constant threat of violent overthrow, creating a unique political dynamic where popular opinion directly influenced imperial policy.
