Crisis of the Third Century

A disastrous scenario emerged after the death of Alexander Severus: the Roman state was plagued by civil wars, external invasions, political chaos, pandemics and economic depression. The old Roman values had fallen, and Mithraism and Christianity had begun to spread through the populace. Emperors were no longer men linked with nobility; they usually were born in lower-classes of distant parts of the Empire. These men rose to prominence through military ranks, and became emperors through civil wars.

There were 26 emperors in a 49-year period, a signal of political instability. Maximinus Thrax was the first ruler of that time, governing for just three years. Others ruled just for a few months, like Gordian I, Gordian II, Balbinus and Hostilian. The population and the frontiers were abandoned, since the emperors were mostly concerned with defeating rivals and establishing their power. The economy also suffered: massive military expenditures from the Severi caused a devaluation of Roman coins. Hyperinflation came at this time as well. The Plague of Cyprian broke out in 250 and killed a huge portion of the population. In 260 AD, the provinces of Syria Palaestina, Asia Minor and Egypt separated from the rest of the Roman state to form the Palmyrene Empire, ruled by Queen Zenobia and centered on Palmyra. In that same year the Gallic Empire was created by Postumus, retaining Britannia and Gaul. These countries separated from Rome after the capture of emperor Valerian by the Sassanids of Persia, the first Roman ruler to be captured by his enemies; it was a humiliating fact for the Romans. The crisis began to recede during the reigns of Claudius Gothicus (268–270), who defeated the Gothic invaders, and Aurelian (271–275), who reconquered both the Gallic and Palmyrene Empires. The crisis was overcome during the reign of Diocletian.
