TL;DR

Historian Anthony Kaldellis argues that the so-called 'Byzantine Empire' was actually the uninterrupted 2,200-year continuation of the Roman state, with its citizens maintaining Roman identity and legal continuity from 753 BC through 1453 AD despite Western historiographical attempts to separate the Eastern Empire from its ancient roots.

🏛️ The 'Byzantine' Misnomer 2 insights

A modern political invention

Western historians called it the 'Empire of the Greeks' for 1,000 years before switching to 'Byzantine Empire' for political reasons, despite all sources confirming the state and its citizens consistently identified as Roman throughout its existence.

Unbroken legal and cultural continuity

The Eastern Roman Empire represented the direct constitutional continuation of the ancient Roman Empire, with subjects remaining Roman citizens from the archaic period through the 15th century without experiencing any perceived rupture in their political identity.

The 2,200-Year Arc 2 insights

Three phases of governance

The Roman state evolved through the period of Kings (753-509 BC), the Republic (509-27 BC), and the Imperial Monarchy (27 BC-1453 AD), with power eventually shifting from Rome to Constantinople as the administrative center.

Reformers shaped the Late Empire

Diocletian's reforms (284-305 AD) established the tax system and bureaucracy characteristic of the Late Roman Empire, while Constantine's founding of Constantinople (330 AD) and conversion to Christianity created lasting structural transformations.

⚔️ Crisis and Resilience 3 insights

Three swift catastrophes defined territorial loss

The empire suffered devastating but rapid territorial losses during the Arab conquests of the 630s, the Seljuk Turk conquest of Asia Minor in the 1070s, and the Fourth Crusade's sack of Constantinople in 1204, contrasting with long periods of slow consolidation and growth.

Extreme violence during instability

During crisis periods, 26 emperors were murdered within just 50 years, nearly all being generals killed by their own troops amid civil wars, hyperinflation, and plague.

Not a military dictatorship

Despite armies frequently determining imperial succession through civil wars, the state rarely employed military force for domestic social control, distinguishing its governance from true military dictatorships.

🚢 The Ship of Theseus 2 insights

Gradual transformation without rupture

Like the Ship of Theseus where every component is replaced yet remains the same vessel, the Roman Empire underwent complete administrative and cultural transformations over centuries without its citizens perceiving a break in their political community's continuity.

State-based versus cultural identity

Unlike Greek or Christian traditions that transcend specific states, Roman history represents the unique evolution of a specific political community where consensus to be ruled and citizenship, rather than ethnic pride, maintained societal cohesion for over two millennia.

Bottom Line

When studying medieval history, reject the artificial distinction between 'Roman' and 'Byzantine' to accurately understand the continuous 2,200-year political evolution of the Roman
