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.
