During his reign the emperor Carus attacked the Persians and conquered Ctesiphon (283), but died by the plague.
After the death of Carus, the army in the East demanded to be led back to Europe, and Numerianus, the younger son of Carus, was forced to comply.
Lucretius Carus (96-55) were entire seclusion from public life and absorption in the ideal pleasures of contemplation and artistic production.
Although Carus severely avenged the death of Probus, he was himself suspected of having been an accessory to the deed.
Having defeated the Quadi and Sarmatians on the Danube, Carus proceeded through Thrace and Asia Minor, conquered Mesopotamia, pressed on to Seleucia and Ctesiphon, and carried his arms beyond the Tigris.
