The Crisis of the Third Century: 26 Emperors in 50 Years

#498 – Anthony Kaldellis: Roman Empire, Byzantine Empire, R… · Jun 30, 2026 History

The Crisis of the Third Century was a genuine perfect storm: 26 emperors murdered in 50 years, hyperinflation, a devastating pandemic potentially killing 5,000 people a day in Rome alone, and the empire fracturing into three pieces. Yet Emperor Aurelian reconquered all of it in five years. The crisis was severe — but it never produced an alternative political imagination. Every rebel general who broke away still set up a Roman state.

Edict of Caracalla

At 1:04:13 · chapter starts 54:20

Kaldellis presents the Edict of Caracalla as a pivot point in Roman history that tends to be underappreciated precisely because it worked so completely. Before 212 AD, at most a third of the empire's free population held Roman citizenship — everyone else had local civic status, subject to local rather than Roman law. Caracalla's Constitutio Antoniniana changed this wholesale. We don't know exactly why he did it — religious gratitude for surviving a coup, tax reasons, and an ideology of unified community have all been proposed — and we don't even have the complete text of the edict, only a damaged papyrus fragment in Greek. But the consequences are unmistakable: Roman citizenship was extended to all free inhabitants and the empire actually implemented it with full legal weight. Within a generation, all the emperors were provincials. When Constantine founded Constantinople a century later, he wasn't bringing Roman civilization to the East — Roman civilization was already there. Kaldellis makes the comparison explicit: no other empire in history did this. The British Empire with India, for instance, was simply unthinkable in those terms.

The Edict of Caracalla: Rome's Greatest Political Experiment

#498 – Anthony Kaldellis: Roman Empire, Byzantine Empire, R… · Jun 30, 2026 History

No modern empire has ever done what Rome did in 212 AD. The Edict of Caracalla extended full citizenship to every free person in the empire — not as a gesture, but with legal teeth. Within a generation, all the most powerful people in the empire were provincials. It is almost impossible to imagine Britain doing this for India, including opening the throne to Indians. Rome did it, and it stuck.

The Missile Markup: How Iran Money Funded the Contras

Selects: Iran-Contra Affair: Shady in the 80s, Part 2 · Aug 8, 2026 History

The Pentagon sold missiles to the CIA for $3,700 each. The CIA sold them to Richard Secord at cost. Secord sold them to Iranian middleman Ghorbanifar for $10,000 each. Ghorbanifar charged Iran even more. The profit — including $3 million in interest in one Swiss account — was diverted directly to fund the Nicaraguan Contras.
