Antony Spared: A Fatal Mistake in Caesar's Assassination

The conspirators who plotted Julius Caesar's assassination on the Ides of March debated whether to kill Mark Antony along with the dictator. Brutus argued against it, insisting that murdering Antony would make the conspiracy look like a power grab rather than a principled defense of the Republic. This decision proved catastrophic. Antony survived, seized Caesar's personal papers and treasury, and delivered a funeral oration that turned the Roman mob against the conspirators. Within days, Brutus and Cassius were forced to flee the city. Antony then allied with Octavian, Caesar's adopted heir, and the general Lepidus to form the Second Triumvirate, which hunted down and executed the conspirators' supporters in a wave of proscriptions that killed over 2,000 senators and equestrians. The decision to spare Antony was the single error that destroyed the conspiracy's chances of success and ensured that Caesar's assassination would lead not to the Republic's restoration but to the creation of an even more powerful autocracy under Augustus.
