Constitution of the Roman Republic [SEP] Sulla's civil war
After winning a second civil war and purging the Republic of thousands of political opponents and "enemies" (many of whom were targeted for their wealth), he forced the Assemblies to make him dictator for the settling of the constitution, with an indefinite term. Sulla also created legal barriers, which would only be lifted during the dictatorship of Julius Caesar some forty years later, against political participation by the relatives of those whom he ordered murdered. And with this use of unprecedented violence at a new level, Sulla was able not only to take control of the state, but also retain control of it, unlike Scipio Nasica or Gaius Marius, both of whom had lost control of the city after deploying force.
