Say the assassination of Julius Caesar and one line comes to mind before any fact does. "Et tu, Brute." You too, Brutus.

Caesar never said that. Suetonius, writing more than a century later, records that he made no reply at all, just a groan, and that only "certain writers" claim he spoke two Greek words to Brutus: "You too, child."

Forty days before the killing, the Senate had voted Caesar dictator for life. Forty days later, twenty three senators voted with knives.

The killing did not save the Republic they said they were saving. It ended it.

Scene 1The Theatre of Pompey, the fifteenth of March

Caesar takes his seat. Senator Tillius Cimber approaches with a petition, and Caesar waves him off.

Cimber grabs Caesar's toga and pulls it off his shoulder. That is the signal.

Publius Servilius Casca strikes first, stabbing Caesar in the neck from behind. Caesar seizes Casca's arm and stabs him back with his stylus.

Then the others close in: Gaius Cassius Longinus, Decimus Brutus, Marcus Brutus, and at least nineteen more.

Caesar falls at the base of a statue of Pompey, the man he had defeated in a civil war four years earlier, in a building that carries Pompey's name.

Suetonius wrote this more than a century and a half after the killing, compiling accounts from people who were not there either.

Suetonius · The Twelve Caesars, Life of Julius Caesar, Chapter 82 · c. 121 CE

“He was stabbed with twenty-three wounds. He said nothing, but merely groaned at the first blow, though certain writers have related that when Marcus Brutus rushed at him, he said in Greek, "You too, child?"”

Twenty three senators stabbed Caesar. The physician who examined the body afterward found that only one of those wounds, the second one, actually killed him.

Every other blow was a man proving he had taken part.

Scene 2The Forum, minutes later

The killers call themselves the Liberatores, the liberators, and they expect the Senate to rally to the Republic they believe they have just saved.

Instead, the Senate flees. The conspirators march to the Capitol carrying their bloody daggers and find the Forum empty.

Marcus Brutus is the conspiracy's moral figurehead, a descendant of the Lucius Junius Brutus who overthrew Rome's last king five hundred nine years before. Gaius Cassius Longinus is the organizer, a veteran commander who resents Caesar's monopoly on power and patronage.

Cassius Dio was writing two hundred seventy years later, about men Caesar had personally pardoned turning on him. He gives Caesar this line as a paraphrase, attributed to him rather than transcribed from anyone who heard him say it.

Cassius Dio · Roman History, Book 44, paraphrased · c. 229 CE

“I have killed many a man in many lands, as a general does on the battlefield, but I have never before spared an enemy and then been betrayed by the one I spared.”

Twenty three of the men who killed Caesar had been pardoned by him. Sulla, the dictator before him, had simply killed nine thousand men rather than take that risk.

Caesar chose mercy. Mercy is what killed him.

Scene 3The Forum, the twentieth of March

Mark Antony, Caesar's co consul, reads the dictator's will aloud at the funeral. Caesar has left his gardens across the Tiber to the people of Rome, and seventy five denarii, about three months' wages for a laborer, to every citizen.

Antony displays Caesar's toga: slashed, blood soaked, pierced with twenty three rents.

Antony did speak that day. Plutarch says so but records no text of the speech at all. A century later, Appian gives Antony this line, though no source any closer to the day confirms he actually said it.

Appian · Civil Wars · second century CE

“Here was a man. When comes such another?”

The crowd already has the will; it needs no convincing. They burn the body on a pyre in the Forum itself, then grab burning branches and run for the houses of Brutus and Cassius.

A poet named Helvius Cinna, no relation to the conspirator Cornelius Cinna, is caught by the mob anyway. They kill him and carry his head through the streets on a spear.

Scene 4Rome, forty three BCE

Caesar's eighteen year old grandnephew and heir, Gaius Octavius, arrives from Apollonia in April to claim his inheritance.

By November, Octavian, Antony, and Lepidus form the Second Triumvirate and proscribe three hundred senators and two thousand equestrians.

Cicero, who had publicly celebrated the killing, is put to death by Antony's soldiers on the seventh of December, forty three BCE. His head and hands are nailed to the Rostra, where he had denounced Antony.

Brutus and Cassius raise armies in the east and are defeated at Philippi in October, forty two BCE. Cassius dies by suicide after the first engagement, Brutus after the second.

Scene 5Actium, the second of September, thirty one BCE

Octavian and Antony turn on each other next. Octavian destroys Antony's fleet at Actium. Antony and Cleopatra flee to Alexandria, where both die by suicide.

In twenty seven BCE, the Senate grants Octavian the title Augustus. He will rule for forty one years. The Republic the Liberatores killed a dictator to save no longer exists.

Five accounts

Five accounts survive the killing of Julius Caesar, and one of them is not about Rome at all. It is about a play written sixteen centuries later that replaced the history it was based on.

  1. Republican: The Last Defenders of Libertas
  2. Caesarian: The Reformer and His Oligarchs
  3. Roman Plebeian: The People's Grief
  4. Provincial: The Conquered Peoples
  5. Shakespeare vs. History: The Play That Shaped Political Imagination

The turn

Each account leaves out exactly what would complicate it.

  1. Republican: The Last Defenders of Libertas

    The Republican case explains the constitutional violation and says far less about the land Caesar redistributed or the clemency he showed the very men who killed him.

    From the record
    Caesar's popular reforms (land redistribution, calendar reform, citizenship expansion)
    The Republic's own dysfunction (corruption, electoral violence, senatorial gridlock for decades before Caesar)
    Caesar's clemency toward defeated enemies, including many of his assassins
    The conspirators' own aristocratic self-interest in preserving senatorial privilege
  2. Caesarian: The Reformer and His Oligarchs

    The Caesarian case counts a century of Republican dysfunction and says almost nothing about the million dead and million enslaved in Gaul that funded the reforms it praises.

    From the record
    Caesar's genocide in Gaul (his own count: 1 million killed, 1 million enslaved)
    Concentration of power in a single individual as a genuine constitutional crisis
    Caesar's manipulation of elections, census, and Senate composition
    The Republic's genuine achievements in limited government and rule of law
  3. Roman Plebeian: The People's Grief

    The plebeian account counts the grain and the land and says nothing about the power that came with them.

    From the record
    Constitutional principles at stake in the assassination
    Caesar's authoritarian methods of concentrating power
    Long-term consequences of replacing republican governance with personal rule
    Manipulation of popular sentiment by Antony and later Octavian
  4. Provincial: The Conquered Peoples

    The provincial account, which names the dead in Gaul in the most detail, still passes over the reforms Caesar extended to conquered peoples in his own lifetime.

    From the record
    Internal Roman constitutional debates about legitimate authority
    Caesar's genuine administrative reforms (calendar, urban planning, legal standardization)
    Integration of provincial elites into Roman governance over subsequent centuries
    Economic development and infrastructure (roads, aqueducts) that accompanied Roman rule
  5. Shakespeare vs. History: The Play That Shaped Political Imagination

    And the academic account, tracing exactly how a play replaced a history, spends its four centuries on Shakespeare's Rome and none on Cleopatra's Egypt, waiting outside the frame entirely.

    From the record
    The actual historical complexity of Roman politics and class dynamics
    Caesar's military conquests and their human cost
    The economic and social conditions of the late Republic
    Non-Western perspectives on and parallels to the assassination

In November eighteen sixty four, the three Booth brothers performed Julius Caesar together on a New York stage.

Five months later, one of them, John Wilkes Booth, assassinated Abraham Lincoln, shouting "Sic semper tyrannis."
