The Man They Feared
Julius Caesar rose from a patrician family of modest means to become the most powerful individual in the Roman world through military genius, political brilliance and willingness to take risks that destroyed more cautious men. His decade of conquest in Gaul produced enormous wealth and a loyally devoted army. His accounts of the campaigns — the Gallic Wars — remain among the most readable military memoirs in history and were part of his political strategy: keeping his name and achievements before the Roman public.
The Conspiracy
The conspirators who planned Caesar's assassination called themselves the Liberatores — the Liberators. Led by Cassius Longinus and Marcus Junius Brutus, they genuinely believed they were saving the Republic from tyranny. Their specific fear: that Caesar intended to declare himself king — the one title Roman culture considered absolutely incompatible with republican governance. On March 15th 44BC, twenty-three senators surrounded Caesar in the Theatre of Pompey and stabbed him. Of the 23 wounds, ancient sources suggest only one was immediately fatal. Caesar pulled his toga over his face as he fell.
The Moment the Plan Failed
Caesar's will was read publicly shortly after his death. He had left money to every Roman citizen. The reaction of the crowd was immediate and violent. The conspirators fled Rome within hours. Caesar's ally Mark Antony seized the political moment. Caesar's great-nephew Octavian, just 18 years old, arrived from Greece and began consolidating his position. The Republic the conspirators had killed to protect would last less than twenty more years.
The Irony of History
The civil wars that followed Caesar's assassination lasted over a decade, consuming lives and the remaining institutional fabric of the Republic. When they ended, Rome was an empire under Augustus — Caesar's heir — with far more concentrated power than Caesar had ever possessed. Twenty-three men stabbed Caesar to prevent a monarchy. They created one. It is history's most perfect illustration of how the means chosen to solve a problem can make the problem immeasurably worse.

Frequently Asked Questions
Why was Julius Caesar assassinated?
Julius Caesar was assassinated on the Ides of March, 15 March 44 BC, by a group of senators who feared he intended to make himself king. The conspirators, led by Brutus and Cassius, believed they were saving the Roman Republic from tyranny. The irony is that their action destroyed the Republic they were trying to protect.
How many times was Julius Caesar stabbed?
Julius Caesar was stabbed 23 times by his assassins. Ancient sources report that only one wound was fatal — a stab to the chest. A Roman physician who examined the body, Antistius, reportedly concluded that Caesar might have survived many of the wounds individually. The large number of stab wounds reflected each conspirator's desire to share responsibility for the act.
Did Julius Caesar say 'Et tu, Brute'?
The phrase Et tu Brute — meaning 'And you, Brutus?' — is almost certainly fictional, popularised by Shakespeare's play Julius Caesar written in 1599. Ancient sources differ on Caesar's last words. Suetonius suggests Caesar pulled his toga over his face as he fell. The Greek historian Plutarch records no last words at all.
Was Julius Caesar a good leader?
Caesar was an extraordinarily capable military commander and political strategist who implemented genuine reforms benefiting ordinary Romans. However he also accumulated unprecedented personal power, undermined republican institutions and triggered a civil war that killed hundreds of thousands. Whether he was a good leader depends on whether you prioritise effectiveness or adherence to constitutional principles.
What happened to Rome after Julius Caesar died?
After Caesar's assassination Rome descended into another civil war between his supporters, led by Mark Antony and Octavian, and the conspirators led by Brutus and Cassius. The conspirators were defeated at the Battle of Philippi in 42 BC. Octavian eventually defeated Antony and became Rome's first emperor — Augustus — ending the Republic the assassins had died trying to save.
A Note From The Editor
The assassination of Julius Caesar is one of history's great cautionary tales — not about tyranny, but about the gap between intention and consequence. Twenty-three men believed absolutely that they were saving Rome. They were educated, principled, convinced of their own righteousness. And they destroyed the very thing they were trying to protect. I think about that gap — between what we intend and what we cause — more than almost anything else in ancient history. Good intentions have never been sufficient protection against catastrophic outcomes.
The Roman Political System Before Caesar
To understand Julius Caesar's significance, it is necessary to understand what he was operating within and ultimately destroying. The Roman Republic had functioned for nearly five centuries through a system of elected magistrates, senatorial oversight, and an elaborate set of constitutional conventions designed to prevent any individual from accumulating too much power. Two consuls served as chief executives for one-year terms. Former magistrates accumulated influence in the Senate. Military commands were temporary and geographically limited.
The system had worked, imperfectly, for centuries. But the second and first centuries BCE subjected it to stresses it was not designed to handle. The conquest of the Mediterranean world had produced enormous wealth that was distributed very unequally. The Italian peasantry had been displaced by slave labour on large estates. The armies, increasingly composed of men with no property to return to, became loyal to their commanders rather than to the state. A series of ambitious men — Marius, Sulla, Pompey — had pushed the constitutional limits in ways that progressively weakened the republic's norms.
Caesar's Rise
Julius Caesar was born in 100 BCE into a patrician family with more history than money. His early political career was financed largely by debt. He was a skilled orator, a populist politician who aligned himself with the interests of the plebs against the senatorial elite, and a military commander of exceptional ability.
His alliance with Pompey and Crassus — the so-called First Triumvirate of 60 BCE — gave him the political backing to secure the consulship and then the command of Gaul. The Gallic campaigns of 58-50 BCE were a decade of extraordinary military achievement. Caesar conquered a vast territory stretching from the Mediterranean to the English Channel, defeated multiple confederations of Celtic peoples, and killed or enslaved millions. He also made himself fabulously wealthy from the spoils, paid off his debts, and built an army of veterans personally loyal to him.
The Rubicon and Civil War
When Caesar's command in Gaul expired in 49 BCE, the Senate demanded that he disband his army before returning to Rome. Caesar knew that without his army, he would be legally vulnerable to prosecution by his political enemies. He made the decision that the Roman world had been dreading: he crossed the Rubicon river — the boundary between his province and Italy proper — with his army, making civil war inevitable.
The civil war that followed lasted until 45 BCE, ranging across the entire Mediterranean world. Caesar defeated Pompey at Pharsalus in Greece in 48 BCE; Pompey fled to Egypt and was murdered. Caesar pursued to Egypt, where he became entangled in Egyptian court politics and began his relationship with Cleopatra. He defeated the remaining Pompeian forces in Africa and Spain, and returned to Rome as undisputed master of the Roman world.
The Assassination and Its Consequences
Caesar's assassination on the Ides of March, 44 BCE, was planned by a group of senators who called themselves the Liberatores — the liberators. They believed, or told themselves they believed, that killing Caesar would restore the republic. They were catastrophically wrong.
The assassination unleashed another round of civil wars that lasted thirteen years and destroyed what remained of the republican system. Mark Antony, Caesar's lieutenant, turned public opinion against the conspirators within days of the assassination. Brutus and Cassius were driven from Rome. The young Octavian — Caesar's great-nephew and adoptive son — emerged as a political force of his own. After years of shifting alliances and military conflict, Octavian defeated Antony and Cleopatra at the Battle of Actium in 31 BCE and became, under the name Augustus, the first Roman emperor.
The republic the conspirators had sought to save had been destroyed in the process of trying to save it. The irony was absolute: the assassination of Caesar, intended to preserve republican government, produced the conditions that made imperial government inevitable.
Caesar's Legacy
Julius Caesar's impact on Western civilisation extends far beyond his political career. The Julian calendar, which he introduced in 46 BCE, was the standard calendar of the Western world for sixteen centuries, and its successor — the Gregorian calendar, introduced in 1582 — is a refinement of it. The month of July bears his name. The title Caesar became synonymous with supreme political authority in the Roman world and its successors: the German Kaiser and Russian Tsar are both derived from it.
His written works — particularly the Gallic Wars — became standard texts in the study of Latin. His name became a common noun in multiple languages. The word "caesarean," used for a surgical procedure, derives from a legend about his birth — almost certainly apocryphal, but indicative of the degree to which his name entered the cultural vocabulary of Western civilisation.
