Taxation in the Roman Empire - historian explains | Anthony Kaldellis and Lex Fridman

Anthony Kaldellis rejects the characterization of Diocletian's bureaucratic reforms as creating a 'deep state' in the modern sense. While acknowledging that large government bureaucracies did develop with officials whose activities weren't always transparent, he argues there's no historical evidence of bureaucrats working to undermine imperial power from within. Lex Fridman suggests that modern democracies incentivize deep state formation because leaders are temporary, whereas emperors had incentives to remain integrated with the bureaucracy.

Kaldellis emphasizes that taxation lies at the heart of understanding Roman Imperial history. Diocletian's major innovation was implementing universal taxation, eliminating Italy's historic tax exemption—a privilege based on the principle that conquerors don't tax themselves. By making all Roman territories subject to the same tax system, including wealthy Italy, Diocletian created what functioned as a progressive flat tax where even elites paid the same rates.

A crucial reform was Diocletian's universal census, which catalogued every taxable asset in the empire, enabling the state to create actual budgets. This framework persisted for over three centuries and even influenced systems beyond the empire's fall.

Regarding social mobility restrictions—such as binding farmers to land and requiring soldiers' sons to serve—Kaldellis argues these were primarily tax enforcement mechanisms rather than indicators of a rigid caste system. He notes that most hereditary occupations (shipping, soldiering, farming) made practical sense for maintaining assets and revenue streams. While farmers bound to land faced real restrictions on fiscal responsibility, Kaldellis emphasizes the broader picture shows high mobility in Roman society, with people moving freely and changing positions. He finds no historical evidence of people complaining about forced conscription into military service, suggesting these weren't experienced as oppressive constraints.
