While the inciting incident of the war is clear, its end is not. One could argue various dates, ranging from 89 BC, when most of the fighting was practically complete, down to November 82 BC and the
Battle of the Colline Gate when an identifiably Italian group of rebels was at last defeated. This article presents events down to the nominal
pacification of the Samnites and Lucanians in 87 BC. The main sources for the course of the war are relatively confused. Appian's account present events roughly geographically, producing a confusing non-chronological account. Livy's summaries indicate that Livy wrote chronologically, but the details of the original Livian volumes are lost. Other sources such as Diodorus (via Photius), Florus, and Velleius Paterclus recount events non-chronologically. There were two main theatres of the war, with one in the north and one in the south. There also was an abortive attempt to incite rebellion in Etruria and Umbria, but the Romans moved quickly and brutally to suppress it. The northern theatre was centred on Asculum (in the lands of the Piceni and Marsi) with the southern theatre in Samnium, Lucania, Apulia, and Campania. The immediate reaction in Rome to the rebellion was one of confusion. After the war's start,
Quintus Varius Hybrida, then a plebeian tribune, set up a permanent court searching around for conspirators who incited the Italians to war. Mouritsen writes of the court, "such stab-in-the-back theories are plausible only when no other explanation is at hand; apparently the Romans did not see any direct connection between the franchise question and the outbreak of the war". It is possible that in the early winter of 90 BC there was an abortive attempt to negotiate a peace before fighting started; if it occurred, the senate refused to negotiate.
90 BC . Actual identification of the bust is disputed. The historical Marius, regardless, was a legate during the early stages of the war. Appian reports that the Italians at the start of the war mobilised some 100,000 men. Rome's Latin allies remained loyal. Rome also continued to control Capua and central Campania, which proved logistically vital. The consuls of the year, elected in a time of relative peace, were
Lucius Julius Caesar and
Publius Rutilius Lupus. The two men had access to experienced legates, both veteran commanders of the wars against
Jugurtha and the
Cimbri:
Gaius Marius and
Lucius Cornelius Sulla.
Initial offensive The Romans levied a massive force over the winter, allowing the consuls of 90 BC to depart for war immediately. All consuls and praetors that year were assigned to Italy; the provincial governors at the start of the war had their terms continuously
prorogued. According to the summary of Livy, Livy included tables of the Latin and foreign communities that sent auxiliaries to join the Romans. Modern estimates of Roman manpower exceed 140,000, split between fourteen legions (two for each consul and one each for ten legates). Rome also conscripted ships and mercenaries from its overseas allies; two
triremes, for example, were taken from
Heraclea Pontica on the Black Sea and returned eleven years later. The initial Italian offensive struck in late 91 and early 90 BC. It was clearly planned with full knowledge of typical Roman strategy and operations. There was a policy of mercy toward pro-Roman combatants in the southern theatre commanded by
Gaius Papius Mutilus; the war also assumed a "distinctive character" in the extent to which Roman soldiers defected to the Italians. For example, when Nola was captured, the Italians were able to induce the defection of most of the Roman soldiers (the officers refused and were starved to death). In the initial offensive, the colony of
Aesernia was put under prolonged siege: the consul Lucius Julius Caesar moved to break it but was unsuccessful; the Romans suffered further reverses, losing
Venafrum,
Grumentum in Lucania, and suffering defeat near
Alba Fucens. The most important victories for the Italians were in Campania and Picenum. In Campania, Mutilus took
Nola,
Herculaneum, and
Salernum, before being stopped at
Acerrae from advancing on Capua. In Picenum,
Gaius Vidacilius,
Titus Lafrenius, and one Publius Ventidius defeated
Gnaeus Pompeius Strabo at
Mount Falernus and forced him to take refuge at
Firmum. Vidacilius took the opportunity then to advance down the eastern Italian coast into Apulia, taking
Canusium. Aesernia fell later in the year after repeated failures by Lucius Julius Caesar to relieve the town; turning south, Caesar attempted to stop Mutilius from forcing the fortress at Acerrae, but both sides found themselves in a series of indecisive engagements.
Roman breakout While attempting to lead his men across a river in the northern theatre on 11 June, the consul
Publius Rutilius Lupus fell in the
Battle of the Tolenus River while fighting against the
Marsi when his undertrained men were routed during the crossing. After this battle, when the huge number of bodies returned to Rome caused a panic, the senate decreed that war dead should in the future be buried on the field. In this same engagement,
Gaius Marius, another of Rutilius' legates and hero of the
Cimbric wars, was able to pull off a decisive victory by forcing the river when alerted to the disaster by the bodies that flowed downstream; he eventually assumed command after Rutilius' replacement was assassinated at false surrender negotiations. Marius, assisted by a flanking manoeuvre by
Lucius Cornelius Sulla, then inflicted a defeat on the Marsi near the
Fucine Lake, which split the Italians in two.
Sextus Julius Caesar, consul in 91 BC and promagistrate this year, moved to relieve Firmum some time in October. Between Sextus' army and Pompey Strabo's forces, Lafrenius' forces
were routed and forced into Asculum, which was then besieged by Strabo. Sextus' forces then forced back Vidacilius into Apulia and placed it too under siege in December. The northern front of the war largely collapsed after these victories. Attempts to incite rebellion in Etruria and Umbria could have opened a third front against Rome, but were quickly suppressed; Appian notes also that the senate acceded to garrisoning Cumae with freedmen, recruited into the army for the first time. With a collapsing northern front and the division of the Italians into two, Italian defeat became largely inevitable. The Italians attempted opening negotiations, inviting
Mithridates VI Eupator of
Pontus to invade, but Mithridates responded equivocally. As Rome started to gain the upper hand, the senate decreed some time around October that consul Lucius Julius Caesar should bring legislation allowing any Italian community that had not revolted or otherwise promptly laid down their arms to elect Roman citizenship. This was passed and became the
lex Julia de civitate; it also removed one of the main causes of the war – be it demands for citizenship or for security of land holdings – and provided that new
tribes would be created for new citizens. Between the citizenship law and the costs of the war, only the Italian hard-liners remained in the field.
89 BC The new consuls for 89 BC were
Gnaeus Pompeius Strabo and
Lucius Porcius Cato. In January, the Marsi attempted to support the rebellions in Etruria and Umbria. The two consuls moved to intercept the Marsi, who were commanded by
Titus Vettius Scato. Strabo defeated the Marsi near Asculum, forcing them into retreat across the snowy mountains. Cato, taking command from Marius,
defeated the Marsi near the Fucine lake, but was himself killed in battle. It is likely that Cato was killed early in the year, leaving only Strabo as consul for the remainder of 89. The Romans continued on the offensive against the Marsi, under the command of legates
Lucius Cornelius Cinna and Marcus Caecilius Cornutus, and forced the Marsi to petition for peace. These victories allowed the Romans a free hand in the
siege of Asculum and freedom to attack into southern theatre from the north. Corfinium was also taken, forcing the Italians to transfer their capital to
Bovianum. The Romans also subjugated the
Vestini and the
Marrucini. By summer, the Romans had pacified the northern theatre, except for Asculum, which was still under siege. Rome also took the offensive in the south. Sulla, commanding an army and supported by a fleet,
besieged Nola and took
Pompeii, defeating an attempt to relieve the cities by
Lucius Cluentius. After the capture of Pompeii, Sulla quickly took
Stabiae and
Herculaneum by June. Sulla then moved into Samnium, subjugating the Hirpini and giving gentle terms, before taking Bovianum by September after a bitter struggle, forcing the Italians to move their capital again to Aesernia (now under their full control). That year, Sulla stood for and won the consulship of 88 BC, with
Quintus Pompeius Rufus as his colleague. Asculum surrendered in November 89 BC after its commander, Vidacilius, committed suicide. For this victory, Pompey Strabo celebrated a triumph on 25 December over Asculum and Picenum. Strabo, however, infamously refused to give any of the plunder to the state, even though the public treasury was empty. Further legislation was enacted to extend the citizenship with the passage of the
lex Plautia Papiria (though the Samnites and Lucanians, still under arms, were excepted). New legislation was also brought by Pompey Strabo to incorporate new colonies in
Transpadane Gaul with Latin rights. The reorganisation of Italy also required the formation of new
municipia as well as surveying of their lands and establishment of their charters. This longer process would continue until the age of Caesar.
88 and 87 BC in 89 BC triggered the
First Mithridatic War. By 88 BC, the war was largely over, except for some isolated holdouts. Elections for the consulship of 88 were delayed by Pompey Strabo's late return to the city, but eventually returned
Lucius Cornelius Sulla and
Quintus Pompeius Rufus. The senate, troubled by news of
Mithridates VI Eupator's invasion of Asia in the east, assigned neither consul to commands against the Italians; Sulla by lot was assigned the command against Mithridates. Early in the year, Pompey Strabo's command in the northern theatre was prorogued and he quickly accepted the surrender of multiple Italian towns and communities, putting an effective end to the war in the north. The remaining northern insurgents fled south to Samnium and Apulia, where the Italians still controlled large tracts of territory. The Italians reorganised around Quintus Poppaedius Silo and designated him supreme commander; according to Diodorus, Silo commanded a force of some 50,000 men, which would have been wildly insufficient to defeat the Romans. Regardless, Silo was able to reverse Roman advances in Samnium and also recapture Bovianum. He then crossed the Apennines and engaged
Quintus Caecilius Metellus Pius in Apulia, where his forces were badly defeated and Silo was killed. Following Silo's death, Italian organised resistance collapsed. For Livy and Appian, his death marks the end of the war. However, a remnant of Samnite and Lucanian rebels fought on in
Bruttium and even sent appeals to Mithridates of Pontus for an intervention in Italy. Faced with death or slavery, they refused to surrender. Late in 88 or in 87, after Sulla's departure for the east, this rebel force unsuccessfully attacked Isiae and
Rhegium near the
Strait of Messina. The outbreak of
a short civil war at Rome in 87 BC allowed them to nonetheless reach a negotiated settlement with the weakened Roman government; the rebels sided with the faction of
Lucius Cornelius Cinna and Gaius Marius after being promised citizenship, the return of hostages and deserters, and the return of all loot taken by the Romans. == Impact ==
