As consul-designate for the Mithridatic War, Sulla was stripped of his eastern command through the tribune P. Sulpicius Rufus’ legislation backing Gaius Marius—triggering the immediate political crisis that led Sulla to use his army in Italian politics.
Sulla led his legions from Campania to seize Rome by force—the first time a Roman commander marched on the city with a field army—overthrowing his opponents’ measures and setting a precedent for military intervention in domestic politics.
After taking control of Rome, Sulla drove key opponents into flight and secured measures declaring Marius, Sulpicius, and others hostes (public enemies), enabling legal persecution and confiscation and escalating political violence.
With Rome temporarily stabilized under his settlement, Sulla left Italy to prosecute the war against Mithridates VI, a departure that allowed anti-Sullan forces to regroup in his absence.
Sulla concluded a settlement with Mithridates at Dardanus, ending the main phase of the First Mithridatic War and freeing Sulla to refocus on the renewed civil conflict in Italy.
Sulla brought his veteran army back from the East, landing at Brundisium and initiating the civil war of 83–82 BCE against the Marian-Cinnan regime and its allies.
Sulla defeated Gaius Marius the Younger at Sacriportus, driving Marian forces into Praeneste and beginning a siege that became central to the final campaign of 82 BCE.
Sulla fought Gnaeus Papirius Carbo near Clusium in an indecisive engagement as the war spread across Italy, with multiple armies maneuvering for advantage.
In northern Italy, Sulla’s ally Q. Caecilius Metellus Pius defeated C. Norbanus at Faventia, further weakening Marian resistance and narrowing Carbo’s strategic options.
Sulla won the decisive battle outside Rome at the Colline Gate, defeating opposing forces (including Samnite and Lucanian elements) and securing control of Italy and the capital.
After victory, Sulla initiated proscriptions—posted outlaw lists with rewards for killings and confiscations—using state-sanctioned terror to eliminate enemies and fund settlements for his veterans.
A special law (Lex Valeria) appointed Sulla dictator legibus faciendis et rei publicae constituendae (“for making laws and reconstituting the republic”), giving him extraordinary authority without a fixed term to remake Rome’s political order.
Sulla’s legislation sought to entrench senatorial supremacy and curb popular agitation: strengthening the Senate’s role in legislation, expanding permanent criminal courts, and restricting tribunes’ ability to drive policy independently.
Having completed key measures, Sulla resigned the dictatorship and retired to private life in Campania—an unusual voluntary surrender of extraordinary power in Roman history.
