For centuries, history books taught us about the fall of Rome and the rise of the Byzantine Empire. Turns out, that’s a made-up story. On the Lex Fridman Podcast, historian Anthony Kaldellis delivers a sharp jab to conventional wisdom: the 'Byzantine Empire' never existed. It was, in every meaningful sense, the unbroken Eastern Roman Empire, whose people called themselves Romans until its final gasp in 1453 AD.

Key Takeaways

  • The 'Byzantine' Name is a Post-Collapse Invention: The term 'Byzantine Empire' was coined by later historians, long after the empire fell, to differentiate it from its earlier Western counterpart. The people living in the Eastern Roman Empire consistently identified as Romans.
  • Unbroken Legal and Cultural Lineage: Kaldellis argues that the Eastern Roman state maintained a continuous cultural, legal, and political identity for over two millennia. This continuity, rooted in Roman law and a shared narrative, held a diverse populace together.
  • Challenging the Burden of Proof: As Kaldellis puts it, “the burden of proof is on those who would assert that what we’ve been calling the Byzantine Empire is something other-... than the Roman Empire, because all of our sources are very clear about this.”
  • Identity Over Geography: Despite shifts in capital, language, and geopolitical focus, the core identity of Roman citizenship and Roman statehood persisted. Emperors like Diocletian, Constantine, and Justinian are figures in continuous Roman history, not separate Byzantine history.
  • Practical Impact of Roman Law: The enduring Roman legal system wasn't just abstract. Kaldellis notes its real-world effect, such as Jewish women having more rights under Roman law than their counterparts elsewhere, proving its operative power.

The Myth of the “Byzantine” Break

Imagine your company, after weathering centuries of market shifts and tech revolutions, is suddenly renamed by future analysts. That’s precisely what Kaldellis says happened to the Roman Empire. The idea of a 'Byzantine Empire' implies a clear break, a new entity born from the ashes of the old. But for the people who lived it, it was simply Rome, evolving. “But in fact, it called itself the Roman Empire. Its subjects were Roman citizens. They called themselves Romans all the way down through to the end and beyond,” Kaldellis tells Lex Fridman.

This wasn't a linguistic oversight. It was a conscious self-identification that unified a sprawling state, even as its administrative structures and dominant language changed. The discussion touches on its unique governance as a 'monarchical republic,' a system that balanced imperial power with traditional Roman legal principles. This internal consistency, far more than any external label, defined its enduring resilience against countless threats.

Continuity Built on Identity and Law

What kept this "Roman Empire" alive and cohesive for so long was its unwavering commitment to its core identity and its legal framework. It wasn't just a geographical area; it was “the history of a state or a political community,” Kaldellis explains. “And it is in gradual evolution, but at no point is there a rupture in that history such that its members would ever think that something dramatic had changed, and that they’re no longer part of that story.”

This continuous narrative, backed by a robust legal system (like the reforms under Justinian) and effective institutions, allowed the empire to adapt without losing its soul. It's a testament to the power of a clear, shared identity—one so strong that it took historians centuries later to invent a reason to divide it. The empire's ability to hold diverse populations together, from Egyptians to Greeks, under the banner of Roman citizenship, highlights the strength of this self-perception.

What to Do With This

Your startup's identity is your most guarded asset, but it’s always evolving. Are you allowing external observers—market trends, competitors' narratives, or even casual internal rebrandings—to subtly rename your 'Roman Empire' into a 'Byzantine' shadow? This week, challenge any narrative that suggests a 'break' in your founding vision or company culture unless you consciously, deliberately chose that rupture. If your early employees still call themselves 'Romans' while the market calls you 'Byzantines,' you have a messaging problem that undermines your true legacy and resilience. Define your breaks, or others will define them for you.
