Explanation: The ultraconservative politician Sulla in the Late Roman Republic would, after being shafted in a political dispute, start a civil war, march on Rome, and overthrow the government. After that, he would have the Senate declare him dictator effectively at swordpoint, and then would go on to murder his enemies, and also some people whose money he wanted to seize. Of course, often their families were murdered too - it wouldn’t do to make oneself future enemies whilst taking care of current ones, now would it?

He would do this in the name of ‘restoring the Republic’, and implemented several (largely short-lived) reforms. Such as reducing the power of democratically-elected officials, crippling the democratic People’s Assemblies, ensure that important votes that were still done by the Assemblies were weighted by wealth (wherein the top ~5% could literally outvote the bottom 95%), and staffing criminal juries with only Senators (largely appointed from his cronies after his purges).

He would then retire to a nice Mediterranean island after having ‘saved’ the Republic from the danger of Roman citizens, and die of worms in his gut. Good riddance.

His actions would exacerbate the long-running tensions between the Optimates (supporters of the rich, like Sulla) and Populares (supporters of the poor), and Rome would encounter three more civil wars in the next ~50 years.
