Why This Collection Matters

The Roman Empire faced an extraordinary concentration of crises during the third century. Emperors were repeatedly overthrown, armies elevated rival candidates, Germanic groups crossed the frontiers, the Sasanian Persian Empire challenged Roman power in the East, epidemic disease struck the population, and the monetary system underwent severe disruption.

During the 260s, Roman political authority fractured dramatically. The Gallic Empire controlled much of the western provinces, while the rulers of Palmyra established control over large portions of the eastern empire. These governments did not necessarily imagine themselves as permanently abandoning Roman identity, but their existence demonstrates how weak central imperial control had become.

The empire nevertheless recovered. Emperors including Aurelian restored territorial unity, and Diocletian later introduced major administrative, military, fiscal, and monetary reforms. His Tetrarchic system divided imperial responsibilities among multiple rulers in an attempt to make the enormous empire more governable and succession more orderly.

The political struggles following the Tetrarchy eventually produced Constantine I. Constantine reunited imperial authority under his own rule, founded Constantinople as a new imperial capital, and transformed the relationship between the imperial government and Christianity. The toleration and restitution policies associated with Constantine and Licinius in AD 313 created a much more favorable legal environment for Christians; describing this simply as Constantine single-handedly “legalizing Christianity” obscures the more complicated process.

The fourth-century Roman Empire was not simply the old empire restored unchanged. Government, army, taxation, religion, imperial ceremony, and coinage had all evolved substantially.

This collection therefore tells a story larger than a single “crisis”: the destabilization, fragmentation, recovery, and transformation of the Roman imperial system between the world of the Antonines and the later Roman Empire.
