The imperial system of the Roman Empire depended heavily on the personality and standing of the emperor himself. The reigns of weak or unpopular emperors often ended in bloodshed at Rome and chaos throughout the empire as a whole. In the third century C.E. the very existence of the empire was threatened by a combination of economic crisis, weak and short-lived emperors and usurpers (and the violent civil wars between their rival supporting armies), and massive barbarian penetration into Roman territory.
