The Jugurthine War took place in 112–106 BC, between Rome and Jugurtha of Numidia, a kingdom on the north African coast approximating to modern Algeria. Jugurtha was the nephew and adopted son of Micipsa, King of Numidia, whom he succeeded on the throne, overcoming his rivals through assassination, war, and bribery.

The war constituted an important phase in the Roman subjugation of Northern Africa, but Numidia did not become a Roman province until 46 BC. Following Jugurtha's usurpation of the throne of Numidia,[1] a loyal ally of Rome since the Punic Wars,[2] Rome felt compelled to intervene.

Jugurtha and Numidia

Numidia was a kingdom located in North Africa (roughly corresponding to northern modern day Algeria) adjacent to what had been Rome's arch enemy, Carthage. King Micipsa died in 118 BC. He was survived by two natural sons, Adherbal and Hiempsal, and his adopted nephew, Jugurtha. It was Micipsa's wish that all three would share his kingdom after his death. After King Micipsa's death, Jugurtha proved to be a ruthless and unscrupulous man who would do anything to achieve what he wanted, including murder, bribery, treachery, and assassination. Jugurtha learned Roman ways and military tactics while commanding the Numidian army under Scipio Aemilianus at the Siege of Numantia.

After Micipsa died, Jugurtha ordered Hiempsal assassinated and Adherbal fled to Rome for assistance against his adopted brother. A Roman commission was sent to Numidia in 116 BC to make peace and divide the country among the two brothers. However, Jugurtha bribed the Roman officials in the commission and the best regions of Numidia were given to Jugurtha. Nevertheless, it was accepted and peace was made. Shortly after, in 113 BC, Jugurtha provoked a war with his brother and cornered Adherbal in Adherbal's capital city of Cirta. Adherbal along with the Romans living there resisted. A second Roman commission was sent and, after being bribed, allowed Jugurtha to take the city. Jugurtha then executed his brother, Adherbal, along with many of the Romans who helped Adherbal defend Cirta. This execution of the Romans moved the Roman Senate to declare war on Numidia in 112 BC.

Numidia between 112 and 105 B.C. and main battles of the war.


The Roman consul Lucius Calpurnius Bestia led an army against Jugurtha but Jugurtha surrendered and was given unusually favourable terms. It appears that Bestia was bribed. So favourable were Jugurtha's terms of surrender that it led to an investigation in Rome. Jugurtha was summoned to Rome, and, upon arrival, he bribed two Roman Tribunes of the Plebs, who in turn protected him and prevented him from testifying. Jugurtha then attempted to arrange for the assassination of a potential rival (his cousin Massiva, who was staying in Rome) and was expelled from the city. In late 110 or early 109 BC Jugurtha defeated a Roman army led by the praetor Aulus Postumius Albinus Magnus, brother of the consul of that year, apparently by using bribery, treachery, and trickery. He then demanded to be recognized as the rightful ruler of Numidia. The Senate refused.


The consul Quintus Caecilius Metellus was sent to North Africa to defeat Jugurtha. For his efforts Metellus was later given the title "Numidicus." Quintus Caecilius Metellus was honest and able as a commander but was buying time in order to maximize his glory when he did actually defeat them. His successful war plan was to destroy Jugurtha's supply lines and this forced Jugurtha to adopt guerilla tactics. An internal Roman struggle developed between Metellus and his subordinate commander (legate), Gaius Marius. Metellus was fully aware of Marius' ambitions in Roman politics and refused for days to allow him to sail to Rome and stand for the consulship. Eventually, Metellus permitted Marius to return to Rome and Marius was elected consul in 107 BC. Metellus was, however, unaware that Marius wanted his command in Numidia. Numidia was not an area designated to be protected by a consul by the Roman Senate. However, the populares passed a law in its Tribal Assembly which gave the command against Jugurtha to Marius in 107 BC. This was significant because the Assembly usurped the Senate's rights and powers in this matter and the Senate yielded.


When Gaius Marius arrived in Numidia, Jugurtha had joined forces with his father-in-law, Bocchus, the King of Mauretania. Marius continued Metellus's plan and won several minor victories, but, just like the earlier Fabian strategy, Jugurtha's tactics prevented a Roman victory. It soon became evident that Rome could not defeat Jugurtha through war. Instead, Bocchus negotiated a peace treaty with the Romans that included betraying and turning Jugurtha over to them and in return, Bocchus received part of the Numidian Kingdom. Jugurtha was thrown into a pit under the Tullianum in Rome to die.


The Jugurthine War clearly revealed the problems of the Republic at that time. The fact that a man such as Jugurtha could rise to power by buying Roman military and civil officials reflected Rome's moral and ethical decline. Romans now sought individual power often at the expense of the state. This was illustrated by Marius's rise to power by ignoring Roman traditions. These events were also observed by Marius's quaestor, Lucius Cornelius Sulla, who later came to rival Marius in the first of the great civil wars of the Late Republic. The beginning of this rivalry, according to Plutarch, was purportedly Sulla's crucial role in the negotiations for and eventual capture of Jugurtha, which led to Sulla wearing a ring portraying the capture despite Marius being awarded the victory for it.

The Roman historian Sallust wrote a monograph, Bellum Jugurthinum, on the Jugurthine War emphasising this decline of Roman ethics and placed it, along with his work on the Conspiracy of Catiline, in the timeline of the degeneration of Rome that began with the Fall of Carthage and ended with the Fall of the Roman Republic itself. Sallust is one of the most valuable sources on the war, along with Plutarch's biographies of Sulla and Marius.
