Gaius Marius in the context of "Sullan proscriptions"

Lucius Cornelius Sulla Felix (/ˈsʌlə/, Latin pronunciation: [ˈɫuːkius kɔrˈneːlius ˈsulːa ˈfeːliːks]; 138–78 BC), commonly known as Sulla, was a Roman general and statesman of the late Roman Republic. Coming to fame for his military exploits, he was the first general during the late republic to march on Rome and win a civil war. After purging his opponents, he assumed the dictatorship, sought to strengthen the republican system by means of reforms to the constitution, and resigned his plenary powers after their enactment.

Sulla held the office of consul twice and revived the dictatorship. A gifted general, he achieved successes in wars against foreign and domestic opponents. Sulla rose to prominence during the war against the Numidian king Jugurtha, whom he captured as a result of Jugurtha's betrayal by the king's allies, although his superior Gaius Marius took credit for ending the war. He then fought successfully against Germanic tribes during the Cimbrian War, and Italian allies during the Social War. He was awarded the Grass Crown for his bravery at the Battle of Nola. Sulla was closely associated with Venus, adopting the title Epaphroditos, meaning favoured of Aphrodite.

The Bellum Octavianum (Latin for "War of Octavius") was a Roman republican civil war fought in 87 BC between the two consuls of that year, Gnaeus Octavius and Lucius Cornelius Cinna. Cinna was victorious by late 87 BC.

Hostilities broke out after Octavius opposed Cinna's attempts to distribute the Italian citizens enfranchised after the Social War into all voting tribes and to recall the outlawed Gaius Marius from exile. Cinna was ejected from the city after a fight in the Forum. He began touring Italy to recruit men, while the Senate in Rome replaced him with Lucius Cornelius Merula, a priest of Jupiter, in the consulship. Cinna took control of the Roman army stationed at Nola and was joined by the exiled Marius. Octavius won the support of the two other Roman generals in the field in Italy, Metellus Pius and Pompeius Strabo; the Samnites, who were formally at war with Rome, joined Cinna. Peter Brunt estimates that Octavius had some 60,000 men at his disposal while Cinna had around twice that.

The cursus honorum (Latin for 'course of honors', or more colloquially 'ladder of offices'; Latin: [ˈkʊrsʊs hɔˈnoːrũː]) was the sequential order of public offices held by aspiring politicians in the Roman Republic and the early Roman Empire. It was designed for men of senatorial rank. The cursus honorum comprised a mixture of military and political administration posts; the ultimate prize for winning election to each "rung" in the sequence was to become one of the two consuls in a given year.

These rules were altered and flagrantly ignored in the course of the last century of the Republic. For example, Gaius Marius held consulships for five years in a row between 104 and 100 BC. He was consul seven times in all, also serving in 107 and 86. Officially presented as opportunities for public service, the offices often became mere opportunities for self-aggrandizement. The constitutional reforms of Sulla between 82 and 79 BC required a ten-year interval before holding the same office again for another term.

The March on Rome of 88 BC was a coup d'état by the consul of the Roman Republic Lucius Cornelius Sulla, who seized power against his enemies Marius and Sulpicius, after they had ousted him from Rome. It was the first time in Roman history that a general ordered his army to march against the Republic.

In 88 BC, Sulla was elected consul and given the command of the war against the king of Pontus Mithridates, who had recently invaded the Roman province of Asia. The same year, Sulla and his colleague Quintus Pompeius Rufus opposed the attempt of the tribune of the plebs Publius Sulpicius to enrol the Italians who received the Roman citizenship at the end of the Social War (91–87 BC). To bypass the consuls' opposition, Sulpicius sought the support of the popular Gaius Marius, who had already been consul six times. Marius demanded for his help that Sulpicius pass a law transferring Sulla's command to him. Using armed gangs to intimidate the tribal assembly, Sulpicius removed Pompeius' consulship and forced Sulla to flee from Rome, after which he enrolled the Italians and gave the Mithridatic command to Marius.

Sulla's civil war was fought between the Roman general Sulla and his opponents, the Cinna-Marius faction (usually called the Marians or the Cinnans after their former leaders Gaius Marius and Lucius Cornelius Cinna), in the years 83–82 BC. The war ended with a decisive battle just outside Rome itself. After the war the victorious Sulla made himself dictator of the Roman Republic.

Sulla's proscription was a reprisal campaign by the Roman proconsul and later dictator, Lucius Cornelius Sulla, to eliminate his enemies in the aftermath of his victory in the civil war of 83–82 BC.

Following his victory at the battle of the Colline Gate, Sulla wanted to take his revenge against the former supporters of Marius and Cinna, who had declared him a public enemy in 87 BC. After having obtained a positive vote from a popular assembly, he published two lists with the names of his enemies among senators and equites, the two tiers of the Roman aristocracy. The lists contained 520 names, of which 75 are known. Those on the lists had their lives and property forfeit; rewards were given to those who assassinated the victims. Several henchmen, as well prominent politicians who supported Sulla, massively profited from the proscription, collecting bounties and receiving seized properties at concessionary prices.

Jugurtha or Jugurthen (c. 160 – 104 BC) was a king of Numidia, the ancient kingdom of the Numidians in northwest Africa. When the Numidian king Micipsa, who had adopted Jugurtha, died in 118 BC, Micipsa's two sons, Hiempsal and Adherbal, along with Jugurtha, were in line for succession. Jugurtha arranged to have Hiempsal killed in 117 BC and, after a civil war, defeated and killed Adherbal in 112 BC.

The death of Adherbal, which was against the wishes of Rome, along with the growing popular anger in Rome at Jugurtha's success in bribing Roman senators and thus avoiding retribution for his crimes, led to the Jugurthine War between Rome and Numidia. After a number of battles in Numidia between Roman and Numidian forces, Jugurtha was captured in 105 BC and paraded through Rome as part of Gaius Marius' Roman triumph. He was thrown into the Tullianum prison, where he was executed by strangulation in 104 BC.

The Cimbrian or Cimbric War (113–101 BC) was fought between the Roman Republic and the Germanic and Celtic tribes of the Cimbri and the Teutons, Ambrones and Tigurini, who migrated from the Jutland peninsula into Roman-controlled territory, and clashed with Rome and her allies. The Cimbrian War was the first time since the Second Punic War that Italia and Rome itself had been seriously threatened.It was the first of many confrontations with Germanic tribes in Roman history that would last for centuries.

The timing of the war had a great effect on the internal politics of Rome, and the organization of its military. The war contributed greatly to the political career of Gaius Marius, whose consulships and political conflicts challenged many of the Roman Republic's political institutions and customs of the time. The Cimbrian threat, along with the Jugurthine War, allegedly inspired the putative Marian reforms of the Roman legions, a view now contested by modern historians.
