Marcus Junius Brutus

Marcus Junius Brutus (Latin: [ˈmaːrkʊs juːniʊs ˈbruːtʊs]; c. 85 BC – 23 October 42 BC) was a Roman politician, orator, and the most famous of the assassins of Julius Caesar. After being adopted by a relative, his legal name became Quintus Servilius Caepio Brutus. He is often referred to simply as Brutus.

Early in his political career, Brutus opposed Pompey, who was responsible for Brutus' father's death. He also was close to Caesar. However, Caesar's attempts to evade accountability in the law courts put him at greater odds with his opponents in the Roman elite and the senate. Brutus eventually came to oppose Caesar and sided with Pompey against Caesar's forces during the ensuing civil war (49–45 BC). Pompey was defeated at the Battle of Pharsalus in 48, after which Brutus surrendered to Caesar, who granted him amnesty.

With Caesar's increasingly monarchical and autocratic behaviour after the civil war, several senators who later called themselves liberatores (liberators) plotted to assassinate him. Brutus took a leading role in the assassination, which was carried out successfully on the Ides of March (15 March) of 44 BC. In a settlement between the liberatores and the Caesarians, an amnesty was granted to the assassins while Caesar's acts were upheld for two years.

Popular unrest forced Brutus and his brother-in-law, fellow assassin Gaius Cassius Longinus, to leave Rome in April 44. After a complex political realignment, Octavian – Caesar's adopted son – made himself consul and, with his colleague, passed a law retroactively making Brutus and the other conspirators murderers. This led to a second civil war, in which Mark Antony and Octavian fought the liberatores led by Brutus and Cassius. The Caesarians decisively defeated the outnumbered armies of Brutus and Cassius at the two battles at Philippi in October 42. After the defeat, Brutus took his own life.

His name has become a synonym and byword for "betrayal" or "traitor" in most languages of Europe. His condemnation for betrayal of Caesar, his friend and benefactor, is perhaps rivalled only by the name of Judas Iscariot, with whom he is portrayed in Dante Alighieri's Inferno. He also has been praised in various narratives, both ancient and modern, as a virtuous and committed republican who fought – however futilely – for freedom and against tyranny.
