Roman Republic

Julius Caesar

Dictator perpetuo

Lifespan · 100 – 44 BCE

A brief orientation

Gaius Julius Caesar was a Roman aristocrat of patrician birth whose political and military career — closely linked to the populares faction of the late Republic — culminated in the destruction of the Republic itself. He served as consul in 59 BCE, conquered Gaul over nearly a decade of military command (58–51), refused to disband his army when the senate demanded it, crossed the Rubicon at the start of 49 with a single legion, defeated Pompey in the resulting civil war, was made dictator (briefly, then for ten years, then for life), and was assassinated on the Ides of March 44 BCE by a conspiracy of senators who hoped to restore the Republic. The hope did not hold. The settlement Augustus reached two decades later was a different form.

The sources

Caesar is unusual in classical history for writing his own narrative — the Commentarii De Bello Gallico and De Bello Civili — in austere third-person prose that became the schoolboy's first Latin author. Cicero's letters to Atticus give the contemporary senatorial reading. Sallust, Plutarch, Suetonius and Cassius Dio provide the longer biographical and analytical treatments. The mid-Renaissance and early-modern political tradition read all of them.

What he changed and what he claimed

Caesar concentrated extraordinary authority in his person and used it. He reformed the calendar (the Julian calendar is named for him), extended Roman citizenship widely, reorganised the provincial administration, settled tens of thousands of veterans on land, and brought into the senate men from outside the traditional aristocracy. His own claim, articulated through proxies in the lead-up to the war and after, was that his dignitas — his standing earned in service to Rome — was being denied by the senatorial faction and that he was acting in defence of it.

The long argument over what to think of him

The reading of Caesar is the central unresolved question of late-Republican history. The senatorial-republican tradition (Cicero in his lifetime, Lucan in the next generation, the long line of republican writers down through the eighteenth century) read him as the man who killed the Republic. A counter-tradition (parts of Plutarch, parts of Suetonius, much of the imperial and many of the modern historical readings) reads him as the figure who reset an institutional order that was already unworkable. The platform does not try to settle this. See the essay Caesar and the collapse of the Republic.

Why he matters for Virtue & Power

Caesar is the single most-read political figure of European history, and arguably the single figure on whose reading the long republican tradition stood or fell. The platform places him at the centre of the late-Republican cluster — alongside Pompey, Cato the Younger, and Cicero — because the literature does.
