Cicero
Rome's greatest orator and a doomed defender of the dying Republic, whose prose shaped Western political thought.

Marcus Tullius Cicero talked his way to the top of a system built to keep men like him out. Born in 106 BCE in a hill town southeast of Rome, he had no consul among his ancestors, which in Roman politics was nearly disqualifying. What he had instead was the sharpest voice in the city. He became Rome's greatest orator, a philosopher who gave Latin a vocabulary for abstract thought, and a front-row witness to the Republic's collapse, which his thousands of surviving letters record almost in real time.
The new man
Romans called a politician with no office-holding ancestors a novus homo, a new man, and the label was rarely kind. Cicero climbed the ladder of magistracies anyway, on schedule, winning each at the youngest age the law allowed through courtroom genius rather than family wealth or a loyal army. The four speeches he aimed at Catiline still open Latin classrooms with their famous first line, quousque tandem, how long will you go on abusing our patience. The summit came in 63 BCE, when as consul he uncovered and crushed the conspiracy of Catiline, an armed plot to seize the state. A grateful Senate hailed him as pater patriae, father of the fatherland. It was the proudest moment of his life, and he never let Rome forget it.
Defender of a dying Republic
Cicero's misfortune was that the Republic he worshipped was already collapsing under the weight of generals with private armies. He spent his last decades trying to prop up the old constitution against the men who dwarfed it, first Julius Caesar, then, after Caesar's assassination in 44 BCE, Mark Antony. Caesar, victorious in civil war, had pardoned Cicero but pushed him to the margins, and he filled the silence by writing philosophy. In fourteen ferocious speeches he called the Philippics, he branded Antony a tyrant in the making. It was a fatal bet. When Antony, Octavian, and Lepidus carved up the empire among themselves in 43 BCE, Antony put Cicero's name near the top of the proscription list, the roll of citizens marked for death.
Head, hands, and afterlife
Soldiers caught him fleeing in December 43 BCE and cut him down. On Antony's orders the hands that had written the Philippics were severed and, together with his head, nailed to the Rostra in the Forum where he had delivered his greatest speeches. The Republic outlasted him by only a few years. His words did far better. His essay On Duties, written for his son in his last year, was read across Europe for the next fifteen centuries, and his treatises on rhetoric and the nature of the state taught Latin prose to the Renaissance and armed the founders of later republics. He kept alive the case he lost in his own lifetime: that liberty rests on law, not on the goodwill of strongmen.
