Lucius Junius Brutus

• 1. Introduction

  ›

  Lucius Junius Brutus died around 500 BC, and yet the questions his life raises have never stopped troubling historians. Was he a real man, or a myth invented to give Rome's republic a heroic origin? Did he truly watch his own sons be executed for treason, or is that story a fable designed to illustrate the cold demands of civic duty? And how did a man who pretended to be a dullard for years end up founding one of history's most consequential political systems?

  The account of Brutus comes primarily from Livy's Ab urbe condita, written centuries after the events it describes. Almost all earlier Roman records were destroyed when the Gauls sacked the city under Brennus in either 390 or 387 BC. That gap in the archive means every claim about Brutus rests on tradition rather than contemporary documentation. Modern historians have challenged nearly every detail: the people, the chronology, even whether the switch from monarchy to republic was a sudden coup or a slow drift across generations. What survives is a figure at the hinge point between a city ruled by kings and a city that would refuse to tolerate kings for centuries.

• 2. A Nephew in Disguise

  ›

  Brutus was the son of Tarquinia, daughter of Rome's fifth king Lucius Tarquinius Priscus, which made him the nephew of the reigning seventh king, Tarquinius Superbus. That family connection was both a danger and an advantage. According to Livy, Tarquinius had already put to death a number of the leading men of Rome, including Brutus' own brother.

  To survive, Brutus adopted a deliberate strategy of self-concealment. He feigned stupidity so convincingly that his uncle's family dismissed him as harmless. The name itself underlines the act: in Latin, brutus translates to dullard. He wore the label like armor.

  The ruse was tested when he accompanied the king's sons on a journey to the Oracle at Delphi. The princes asked the oracle which of them would next hold power in Rome. The Oracle responded that the first among them to kiss their mother would hold supreme sway. The king's sons understood this literally and planned to rush home to their mother. Brutus read the riddle differently. He interpreted "mother" as Gaia, the earth itself, pretended to trip, and kissed the ground. That small theatrical stumble, performed in front of the men he planned to overthrow, may be the most consequential feigned accident in Roman legend.

• 3. Lucretia and the Breaking Point

  ›

  Sextus Tarquinius, the king's son, raped the noblewoman Lucretia. That act became the trigger for everything that followed. Lucretia summoned Brutus along with Spurius Lucretius Tricipitinus, Publius Valerius Poplicola, and Lucius Tarquinius Collatinus to Collatia. She told them what had happened, then, believing the rape had dishonoured her and her family beyond repair, stabbed herself to death with a dagger.

  According to legend, Brutus took the dagger from Lucretia's body immediately after her death and called out for the overthrow of the Tarquins. The four men then gathered the youth of Collatia and marched to Rome. Brutus summoned the people to the forum and urged them to rise against the king.

  Later accounts, including Livy's, describe Brutus as holding the office of tribunus celerum, a cavalry command, at this moment. Cicero disputes this and places him instead as a private citizen. The distinction matters because it touches on whether the revolt had any formal institutional standing or was a purely popular uprising. The people voted to depose the king and banish the royal family.

  Tarquinius Superbus was conducting a military campaign near Ardea when word reached him. He rode to Rome at speed, but found the city gates closed against him. The army sided with the coup leaders, and the king's sons were expelled. Tarquinius fled into exile with his family, and Tacitus later credited Brutus with "establishing liberty and the consulate."

• 4. The Oath and the New Order

  ›

  Brutus' first recorded act after the expulsion was not administrative but ceremonial. He brought the Roman people together and made them swear an oath: that they would never again permit any man to be king in Rome. The oath Livy preserves in the conspirators' own voice addresses Lucius Tarquinius Superbus directly, pledging prosecution "by sword, by fire, by any means hence" so that neither he nor anyone else would rule Rome.

  There is no scholarly consensus that this oath actually took place. Plutarch and Appian both report it, but differently from each other. What is not disputed is its downstream force. The spirit of the oath, and the figure of Brutus who administered it, inspired later Romans for centuries. His descendant Marcus Junius Brutus would invoke it directly when he joined the conspiracy against Julius Caesar, after a co-conspirator named Cassius reminded him of the ancestor who had expelled a would-be king.

  Brutus and Lucretia's widowed husband Lucius Tarquinius Collatinus were elected as the two first consuls of Rome in 509 BC by the Varronian calendar. Tradition holds that Spurius Lucretius Tricipitinus, appointed interrex by Brutus, conducted the election. Among the institutions later Romans attributed to Brutus' consulship: the taking of auspices before entering office, use of the curiate assembly to bestow consular imperium, expansion of the senate by adding the minores gentes, and the dedication of a temple to Carna on the Coelian hill. A new office, rex sacrorum, was created to handle the religious duties that had belonged to the kings.

• 5. Sons Condemned

  ›

  The Tarquinian family did not accept exile quietly. Their ambassadors returned to Rome and set about subverting prominent citizens, forming what became known as the Tarquinian conspiracy. Among those recruited were two brothers of Brutus' wife Vitellia and, more devastatingly, Brutus' own two sons: Titus Junius Brutus and Tiberius Junius Brutus.

  The conspiracy was discovered. The consuls decided the punishment should be death. Brutus was present at the execution of his sons and watched it through. Livy notes that he showed emotion during the punishment but did not intervene. Later Romans held this up as an example of almost inhuman civic commitment: the man who had freed Rome refused to let family loyalty undo what he had built.

  Not long after, Brutus forced his co-consul Collatinus to resign, or otherwise removed him from office. The stated reasons vary: either Brutus resented Collatinus's family ties to the Tarquins, or he judged his co-consul too lenient with the conspirators. Publius Valerius Poplicola, who had been present at the night of Lucretia's death, was elected suffect consul in Collatinus's place.

  Søren Kierkegaard later read Brutus' willingness to execute his own sons in his work Fear and Trembling, placing it alongside the examples of Agamemnon and Jephthah as an illustration of what he called "tragic heroism" , a category he presented in stark contrast to the faith of Abraham.

• 6. Death at Silva Arsia

  ›

  Tarquinius Superbus made one final attempt to retake Rome by force. He gathered the armies of Tarquinii and Veii and met the Romans at the Battle of Silva Arsia. Valerius commanded the Roman infantry; Brutus commanded the cavalry. Leading the Etruscan cavalry on the other side was Arruns Tarquinius, the king's son.

  Arruns spotted Brutus from a distance by reading the lictors who accompanied him, the ceremonial attendants that marked a consul's presence. Recognising who was in command, Arruns spurred toward Brutus. The two men, who were cousins, charged each other directly and drove their spears into each other simultaneously. Both died on the field.

  The battle itself was inconclusive at first. The right wing of each side routed the other's left. The forces from Tarquinii pushed the Romans back; the Veientes were scattered. Eventually the Etruscan forces withdrew, and Rome claimed the victory.

  The surviving consul Valerius celebrated a triumph and then held a funeral for Brutus with what the sources call great magnificence. The noblewomen of Rome mourned him for a full year, specifically in honour of his vengeance for Lucretia's violation. Polybius reports that during his brief consulship Brutus also signed a treaty with Carthage and oversaw the dedication of the Capitoline temple. These two acts, along with the Roman sources' unanimous attribution of the consulship to him, form what scholars consider the strongest evidence that Brutus was a historical person rather than a pure invention.

• 7. Myth, Politics, and Posterity

  ›

  Marcus Junius Brutus, the most notorious of Julius Caesar's assassins, claimed direct descent from Lucius Junius Brutus. He made that connection visible twice in coin form: first on a denarius while serving as triumvir monetalis in 54 BC, then on a gold aureus minted in the final months of the Liberators' civil war in 42 BC. The portrait of the founder appeared on currency at the moment his descendant was staking everything on killing a man accused of wanting to make himself a king.

  Shakespeare gave the connection its most quoted form. In The Tragedie of Julius Caesar, Cassius tells Marcus Brutus that there was once "a Brutus" who would sooner have tolerated the eternal devil in Rome than a king. That line from Act 1, Scene 2 is not merely dramatic flourish. It is a precise record of how the original Brutus was weaponised in political argument.

  The founder appeared in other literary forms too. He is a leading character in Shakespeare's Rape of Lucrece, a figure in Benjamin Britten's opera The Rape of Lucretia, which drew on André Obey's play Le Viol de Lucrece, and the title character of Nathaniel Lee's Restoration tragedy Lucius Junius Brutus; Father of his Country. That last work was banned in December of 1680, before the Glorious Revolution, for casting Whig political values, including no royal prerogatives and the encouragement of trade, as Roman republicanism.

  By the Enlightenment his image had spread further still. In 1789, at the opening of the French Revolution, Jacques-Louis David publicly exhibited The Lictors Bring to Brutus the Bodies of His Sons, a politically charged painting that provoked controversy precisely because its subject was so legible. Guillaume Guillon-Lethiere treated the same scene a year earlier in Brutus Condemning His Sons to Death in 1788. The memory of Brutus also moved Italian patriots, including those who established the short-lived Roman Republic in February 1849. Whether the man himself existed exactly as described or not, the figure he became shaped republics that came long after Rome.
