Frequently asked questions

Caius Marius (157-85 BC) was a Roman general and statesman, famous for having been elected consul seven times, an absolute record under the Republic. What matters most is that he was a homo novus, that is, a “new man”: none of his ancestors had been consul. A native of Arpinum, a small town in Latium, he embodies the rise of a modest provincial family in a Rome dominated by the nobility. This distinctiveness partly explains his rivalry with the aristocracy and his strong bond with the common people.

Works & Achievements

Reform of the Roman army (107 BC)

Opening recruitment to citizens without property (capite censi) and professionalizing the legions. This reform transformed Rome lastingly and bound soldiers to their generals.

Victory over Jugurtha (105 BC)

End of the long Numidian War through the capture of King Jugurtha. Marius gained immense political prestige from it.

Creation of the eagle as the legionary standard (around 104 BC)

Marius made the silver eagle the sole and sacred emblem of each legion, strengthening the discipline and identity of the troops.

Victory of Aquae Sextiae over the Teutons (102 BC)

Crushing the Teutonic invasion near Aix-en-Provence. This victory saved Roman Provence from disaster.

Victory of Vercellae over the Cimbri (101 BC)

Annihilation of the Cimbri on the Po plain, permanently removing the Germanic threat. Marius was hailed as the savior of Rome.

Standardization of equipment and training (around 104-102 BC)

Standardizing the weaponry supplied by the State and intensive training of the legionaries, including the sarcina (individual pack).

Seven consulships (107-86 BC)

Marius was elected consul seven times, five of them consecutively, an absolute record under the Roman Republic.

Anecdotes

Marius was nicknamed "the third founder of Rome" after Romulus and Camillus, because he had saved the city from the Germanic invasions. Yet this hero came from a modest family in Arpinum: he was a "new man" (homo novus), with no consul among his ancestors, which was extremely rare in a Rome dominated by the nobility.

Before the decisive battle against the Teutons at Aix-en-Provence in 102 BC, Marius deliberately had his soldiers camp facing the immense enemy army, which marched past for six whole days. He wanted his men to grow used to the sight and the terrifying war cries of the Germans so they would no longer fear them on the day of battle.

Marius transformed the Roman army by allowing the poorest citizens, the capite censi, to enlist. From then on the State supplied the equipment. Because the soldiers carried all their own gear to lighten the baggage trains, they were jokingly nicknamed "Marius' mules."

Old and fallen from favor, Marius had to flee his enemies and hid for a time in the marshes of Minturnae. According to tradition, a soldier sent to kill him was so awed by the old general's gaze and voice that he fled without daring to strike.

The rivalry between Marius and his former lieutenant Sulla degenerated into civil war, the first in Roman history. In 87 BC, Marius retook Rome by force and had himself elected consul for the seventh time, fulfilling an old prophecy, but he died a few days after taking office.

Primary Sources

Plutarch, Parallel Lives, Life of Marius (c. 100 AD)
Because he was of humble birth and owed everything to his own courage, they called him a new man. His entire life was a struggle against the nobility of Rome.
Sallust, The Jugurthine War (c. 41 BC)
Marius declared to the people: “To vouch for my loyalty I cannot display the portraits of my ancestors, nor the triumphs and consulships of my family, but, if need be, spears, a banner, military decorations, and scars borne upon my chest.”
Plutarch, Life of Marius (on the battle against the Cimbri) (c. 100 AD)
The plain of Vercellae was strewn with the dead; it is said that more than a hundred thousand Barbarians were killed or taken prisoner, and Marius received the honours of the most brilliant triumph.
Velleius Paterculus, Roman History (c. 30 AD)
Marius was a man of whom one could not say whether he was greater in war or more disastrous in peace: as much as he saved the State by arms, so much did he tear it apart through his furies.
