Averni

Rome, to protect its ally Massilia and ensure communications with Spain, annexes a strip of territory between the Cevennes and the Alps in 121, establishing the first Roman province in France, Gallia Transalpina ("Gaul across the Alps"), an area roughly equivalent to the modern Provence and Languedoc, and later known as Gallia Narbonensis ("Narbonese Gaul").

The Provençal city of Nimes, located about 65 miles (105 kilometers) northwest of Massilia, comes under Roman control but its continued importance is assured by its location on the Via Domitia, the main Roman road between northern Italy and Spain.

The Roman proconsul Domitius Ahenobarbus undertakes a war in 121 BCE against the Allobroges, who have allied with the Arverni under Bituitus.

These Gallic tribes are defeated near the town of Vindalium, the current French town of Bédarrides.

After this defeat, the Allobroges and Arverni make preparations to renter battle with the Romans.

Bituitus again takes the field with an large army.

Where the Isar meets the river Rhone in the south of France, the consul Fabius Maximus, the grandson of Paullus, meets them in battle in the autumn of 121 BCE.

The Romans are greatly outnumbered yet manage to gain a complete victory.

It is estimated that 120,000 of Bituitus' army fell in the battle.

Following his defeat, Bituitus is taken prisoner and sent to Rome.

The Arverni had once been the most powerful tribal hegemony in Gaul during the third and second centuries BCE under their king, Luernios, but with the defeat of his son (or grandson) Bituitus, their ascendancy passes to the Aedui and Sequani.

Unlike the Allobroges, who have been brought under direct Roman rule as a result of the Celtic wars of the 120s, the Arverni negotiate a treaty that preserves their independence, though their territory is diminished.

No further Arvernian kings are mentioned in the historical record, and they may have adopted a constitutional oligarchy at this time.

Quintus Fabius Maximus Allobrogicus, successful in his conquest of Gallia Transalpina, is awarded the honor of a triumph and given the agnomen Allobrogicus.

The triumph he holds becomes famous for its spectacle, including the captive Arvernian king Bituitus in his silver ceremonial armor.

From the plunder of the Auvergne, Fabius erects the Fornix Fabianus (121 BCE; since destroyed) crossing the Via Sacra at the Forum Romanum and and adorns it with a statue of himself; it is the earliest such construction in the Roman Forum.

Bituitus is sentenced by the senate to exile in Alba Fucens, one of three foreign kings known to have been held there (the others are Syphax of Numidia and Perseus of Macedonia).

Bituitus' son, Congonnetiacus, had also been captured, and is possibly held with him at Alba.

It is to be the last time a foreign king is detained at Alba, and throughout the rest of the Late Republican period, kings are known to have been detained at Rome, often in the homes of high-ranking officials, and to have agitated actively in political affairs.

The consuls lead their armies on their own armed migration to the Rhône River near Orange, Vaucluse, where, disliking and distrusting each other, they erect separate camps on opposite sides of the river; by so doing they leave their disunited force open to separate attack by the migrating Cimbri and Teutones.

The overconfident Caepio foolishly attacks without support from Maximus; his legions are wiped out and his undefended camp overrun.

The now isolated and demoralized troops of Maximus are then easily defeated.

Thousands more are slain trying desperately to rally and defend his poorly positioned camp.

Only Caepio, Maximus, and a few hundred Romans escape with their lives across the carnage-choked river.

The Battle of Arausio is the costliest defeat Rome has suffered since Cannae and, in fact, the losses and long-term consequences are far greater.

Though the actual casualty figure remains debated, Livy claims that the total number of Roman casualties (not including camp followers or other noncombatants) amounted to eighty thousand.

Theodore Mommsen claims that besides the eighty thousand Roman soldiers, half as many of the auxiliaries and camp-followers perished.

Plutarch, in his "Life of Marius," did mention that the soil of the fields the battle had been fought upon were made so fertile by human remains that they were able to produce "magna copia" (a great quantity) of yield for many years.

For the Cimbri and Teutons it is a great (though temporary) triumph.

Instead of immediately gathering their allies and marching on Rome, the Cimbri proceed to Hispania, while the Teutones remain in Gaul.

Why they again failed to invade Italy remains a mystery.

Perhaps they thought easier plunder could be found in Gaul and Spain.

It is also possible that, owing to their reckless battle tactics, the Germans had suffered heavy casualties in their victories over the Romans and decided they were not yet strong enough to engage them on their home ground.

Unfortunately for them, they would soon be faced with one of the greatest Roman generals at the head of a new and much deadlier army.

The Cimbri’s Conflict with the Arverni and the Rise of Gaius Marius (c. 106–104 BCE)

After their series of victories over the Romans (113–107 BCE), the Cimbri next clashed with the Arverni, one of the most powerful Celtic tribes in Gaul. Despite their earlier success against the Romans, the Cimbri faced fierce resistance from the Arverni, leading to a hard-fought struggle.

The Cimbri's Decision to Move Toward the Pyrenees

• Rather than immediately marching into Italy, the Cimbri changed course and set out for the Pyrenees, possibly seeking new territories or trying to avoid prolonged warfare in Gaul.
• This diversion delayed their direct conflict with Rome, allowing the Romans a critical period to regroup and strengthen their defenses.
• The temporary absence of the Cimbri from Italy created an opportunity for Rome to reevaluate its military strategies.

The Election of Gaius Marius: Rome’s Response to the Cimbrian Threat

• With Rome in crisis following a string of humiliating defeats, the Senate and the Roman people turned to a proven military leader: Gaius Marius.
• Marius, a skilled general and veteran of previous wars, was elected consul in 107 BCE and again in 104 BCEto deal with the escalating barbarian threat.
• His military reforms would revolutionize the Roman army, including:
  • The recruitment of landless citizens (breaking the traditional property requirements for soldiers).
  • Reorganization of the legions, improving discipline and battlefield effectiveness.
  • Standardization of weapons and training, making Rome’s army more adaptable and efficient.

The Turning Point in the Cimbrian War

• The Cimbri’s decision to delay their advance into Italy gave Rome the breathing space it desperately needed.
• Marius' leadership and reforms ultimately transformed Rome’s military and prepared it for the decisive battles that would culminate in Rome’s final victory over the Cimbri and their allies in 102–101 BCE.
• This period marked the beginning of Marius’ dominance in Roman politics and set the stage for future power struggles in the late Republic.

The Cimbri’s diversion toward the Pyrenees inadvertently led to the rise of Rome’s greatest military reformer, ensuring that when they finally returned, they would face a far more formidable Roman army led by a strategic mastermind.

The location of the final battle between the Aedui and their enemies, which Caesar names as the Battle of Magetobriga, remains unknown, but Ariovistus’ fifteen thousand men turn the tide, and the Aedui become tributary to the Sequani.

Cicero will write in 60 BCE of a defeat sustained by the Aedui, perhaps in reference to this battle.

Ariovistus seizes a third of the Aeduan territory, settling one hundred and twenty thousand Germans there.

In order to avoid infringing on his allies for the moment, Ariovistus must have passed over the low divide between the Rhine and the Doubs in the vicinity of Belfort and then have approached the Aedui along the Ognon river valley.

That move leaves the Sequani between him and the Jura mountains, not a tolerable situation for either if they are not going to be allies.

Ariovistus makes the decision to clear out the Sequani from the strategic Doubs valley and repopulate it with Germanic settlers.

He demands a further third of Celtic land for his allies the Harudes.

Caesar makes it clear that Germanic tribes are actually in the land of the Sequani and are terrorizing them.

They are said to have controlled all the oppida, but this statement is not entirely true, as Vesontio is not under Germanic control.

Presumably, the country to the north of there is under Germanic control.

By the end of the campaign, the non-client Suebi, under the leadership of Ariovistus, stand triumphant over both the Aedui and their co-conspirators.

Rome, fearing another mass migration akin to the devastating Cimbrian War, and now keenly invested in the defense of Gaul, will be drawn irrevocably into war.

Ariovistus, chieftain of the Germanic Suebi tribe, had resumed the tribe’s migration from eastern Germany to the Marne and Rhine region in 71 BCE.

Despite the fact that this migration encroaches on Sequani land, the Gaulish Sequani seek Ariovistus’ allegiance against the Aedui, a numerous Celtic people occupying the drainage system of the upper Loire.

They are nearly between their neighbors to the northeast, the Sequani, who occupy the Doubs river valley, and the Arverni in the Massif Central.

When, in about 62 BCE, a Gaulish Roman client state, the Arverni, conspires with the Sequani and the Germanic Suebi nation east of the Rhine to attack the Aedui, a strong Roman ally, Rome turns a blind eye.

The Romans appear to be unconcerned about a conflict between non-client, client and allied states.

the Suebic leader Ariovistus and the events he was part of are known from Caesar's Commentarii de Bello Gallico.

Caesar, as a participant in the events, is a primary source, although as his Commentaries are in part political propaganda they may be suspected of being self-serving.

Later historians, notably Dio Cassius, are suspicious of his motives.

Caesar does not say what the cause of the conflict was, but the Sequani control access to the Rhine river along the valley of the Doubs.

To that end, they have gradually built up an oppidum or fortified town at Vesontio.

Tradesmen headed up the Rhone and its tributary the Saône (the ancient Arar) cannot pass the Doubs at Vesontio without coming to terms with the Sequani, nor can anyone pass from the Rhine to the Rhone except on similar terms.

The east of the entire great channel is bordered by the Jura mountains and the west by the Massif Central.

Vesontio is seventy-five miles (one hundred and twenty-one kilometers) from that stretch of the Rhine between Mulhouse and Basel.

The Arar forms part of the border between the Aedui and the Sequani.

Strabo, who lived a generation after Caesar in the late republic and early empire, does make a statement concerning the cause of the conflict between the Sequani and Aedui, and it was in fact commercial, at least in Strabo's view.

Each tribe claimed the Arar and the transportation tolls from traffic along it, "but now", says Strabo, "everything is to the Romans."

The Sequani also habitually supported the Germans in their previous frequent expeditions across the river, which shows that Ariovistus’ subsequent devastation of Sequani lands represented a new policy.

The Sequani reward Ariovistus with land in 61 BCE following his victory in the Battle of Magetobriga.

Ariovistus settles the land with one hundred and twenty thousand of his people.

When twenty-four thousand Harudes join his cause, Ariovistus demand that the Sequani give him more land to accommodate the Harudes people.

This demand 'concerns' Rome because if the Sequani concede, Ariovistus will be in a position to take all of the Sequani land and attack the rest of Gaul.

By this time, the Helvetii are well on their way in the planning and provisioning for a mass migration under the leadership of the wealthy aristocrat Orgetorix, who has persuaded the Helvetians to attempt to migrate from Helvetian territory to southwestern Gaul (modern-day France).

The reasons for their migration are mentioned by Caesar in separate passages as either harassment by the Germanic tribes, or not being able to in turn raid for plunder themselves due to their situation in hilly and mountainous territory.

Via council and parley, Orgetorix makes clandestine negotiations with the ambitious Sequani and the Roman-dominated Aedui.

The Sequani are beginning to resent and regret the abundance of unruly Germanic war bands and their huge encampments of dependents.

The Aedui are loath to obey the Roman spur any longer than they must and are keen to revisit their former days at council.

The parley for the trek is successful and Orgetorix is granted passage, and with the trek ratified by council, an army is called up and provisioned.

During this process, Orgetorix had also succeeded in making a personal alliance with the Sequanii chieftain Casticus and the Aedui chieftain Dumnorix through marital arrangements and host exchange of family members.

Orgetorix's Gallic rivals allege that these political successes and displays of diplomacy are intended to benefit Orgetorix alone and their claims are made more convincing by Roman intrigues and impositions.

Mark Antony’s Role in the Gallic Wars and the Carnutes’ Revolt (54–52 BCE)

By 54 BCE, Mark Antony had become a staff officer in Caesar’s armies, assisting in military campaigns in Gaul and Germany. His close friendship and family ties with Caesar ensured that he remained a key supporter, making himself constantly available for Caesar’s military efforts.

Antony, though an able commander, had a disruptive personality, which would later create political tensions in Rome. However, in the Gallic Wars, he proved his military competence, playing a vital role in Caesar’s campaigns against the Gallic revolts, particularly the Great Revolt of 52 BCE, led by Vercingetorix.

The Rise of Vercingetorix and the Pan-Gallic Revolt (52 BCE)

• Previous Gallic revolts, such as the Eburones uprising under Ambiorix in 54 BCE, had failed to secure widespread tribal support.
• In early 52 BCE, while Caesar was in Cisalpine Gaul raising troops, Vercingetorix, a chieftain of the Arverni, managed to unite the Gallic tribes against Rome.
• His father, Celtillus, had been executed for attempting to rule all of Gaul, but Vercingetorix succeeded in achieving this goal, adopting modern warfare strategies to counter the Romans.

The Carnutes: The Sacred Center of Gaul and the Catalyst for Rebellion

• The Carnutes, a powerful Gallic tribe, inhabited the region corresponding to modern Eure-et-Loir, Loiret, and Loir-et-Cher.
• Their territory was considered the sacred center of Gaul, where Druids held their annual pan-Gallic synod.

Political Organization:

• Like several other large Gallic polities, the Carnutes had previously been ruled by kings but later adopted an oligarchic or proto-republican system.
• Rome preferred to deal with client states through kings rather than fractious councils or senates, making it easier to control them through centralized power.

Caesar’s Imposed Rule Over the Carnutes

• After his campaign against the Belgae in 57 BCE, Caesar set up a protectorate over the Carnutes and installed Tasgetius as king, choosing him from the ruling clan as a reward for loyalty.
• Tasgetius’ rule was presented as a restoration, as his ancestors had once held supreme power.

However, in 54 BCE, Tasgetius was assassinated, which Caesar blamed on an anti-Roman faction among the Carnutes.

• Some historians argue that this was a result of normal internal Gallic politics, but Caesar used the assassination as a propaganda tool to justify further conquest.
• Following Tasgetius’ death, the Carnutes were placed under the control of the Remi, Rome’s most loyal Belgic ally.

The Carnutes Revolt and the Beginning of the Great Gallic Rebellion

• In early 52 BCE, the Carnutes, led by Cotuatus and Conetodunus, initiated the revolt, believing that Caesar was distracted by the political turmoil in Rome following the murder of Publius Clodius Pulcher.
• On February 13, 52 BCE, in the oppidum of Cenabum, the Carnutes massacred all the Roman merchants and killed one of Caesar’s commissariat officers.

This act served as a rallying cry for rebellion, and the uprising spread rapidly throughout Gaul, culminating in the formation of a united Gallic resistance under Vercingetorix.

Caesar’s Ruthless Response: The Destruction of Cenabum

• In retaliation, Caesar marched on Cenabum, the prosperous capital of the Carnutes.
• He burned the city, slaughtering the men and selling women and children into slavery.
• The booty from the sacking of Cenabum was distributed among his soldiers, providing a financial incentive to continue the conquest.

Significance of the Carnutes’ Revolt

• The massacre at Cenabum was the spark that led to the largest and most organized Gallic rebellion against Rome.
• The Carnutes’ rebellion demonstrated that anti-Roman sentiment had spread beyond individual tribes, unifying large sections of Gaul.
• Caesar’s brutal suppression of the revolt sent a clear message to other rebellious tribes about the consequences of defying Roman rule.

Despite the initial success of Vercingetorix, the rebellion would ultimately fail at the Siege of Alesia, solidifying Rome’s conquest of Gaul. However, the Carnutes’ role in initiating the Pan-Gallic uprising ensured their place in Roman and Gallic history as a symbol of defiance against Rome.
