During the Roman Empire, outbreaks of civil war (and the assassinations which often preceded them) were generally intended to change the emperor, not the imperial system. Even though there was a brief moment after the emperor Caligula’s assassination in AD 41 when a change in the political system might have been triggered, the rudderless and leaderless soldiers quickly reverted to the reassuring default mode of imperial rule after conveniently finding Claudius hiding behind a curtain and making him emperor.
