Setting the scene
By 44 BCE, Julius Caesar was dictator for life, having won the civil war against Pompey. He had enacted reforms—calendar reform, debt relief, expanding citizenship—but also accumulated unprecedented power, accepting honors that seemed monarchical. Many senators, led by Brutus and Cassius, feared Caesar intended to make himself king, destroying the Republic. They were also motivated by personal grievances and idealistic republicanism. A conspiracy of about 60 senators formed.
What happened
On March 15, 44 BCE (the Ides of March), Caesar attended a Senate meeting at the Theatre of Pompey. The conspirators surrounded him, and despite warnings from a soothsayer and his wife Calpurnia, Caesar went. They stabbed him 23 times. According to Suetonius, Caesar initially resisted but when he saw Brutus, his protégé, among the attackers, he pulled his toga over his face and said 'kai su, teknon?' (you too, child?)—Shakespeare rendered this as 'Et tu, Brute?' Caesar died at the foot of Pompey's statue.
Why it still matters
Caesar's assassination failed to save the Republic—it triggered another civil war that ended with his heir Octavian (Augustus) becoming emperor. The assassination demonstrated that killing a tyrant does not restore institutions once they've decayed. Caesar became a martyr, deified by the Senate, and his name became synonymous with emperor (Kaiser, Tsar). The Ides of March remains history's most famous assassination, symbolizing betrayal and the dangers of political violence. Shakespeare's play immortalized the event, shaping Western understanding of tyranny and republicanism.
Background
The murder triggered new rounds of civil war. Even centuries later, this episode remains a reference point for how empires rise, fracture, and transform.
