What happened — and why
Rome destroys Carthage (146 BC)
The Third Punic War. Carthage is razed to the ground, its earth sown with salt. In that same year Corinth — a symbol of Greek culture — is destroyed. Rome becomes the sole power of the Mediterranean.
The philosophical cause
Cato the Elder ended every speech in the Senate with a single phrase: "Carthage must be destroyed." Fear of a rival was stronger than political calculation.
Victory corrupted the victor. Wealth from the provinces, slaves from the conquered lands — and peasants left without land. The Gracchi will try to fix it. They will be killed.
The Gracchi brothers: the first attempt at reform — and the first political massacre
Tiberius Gracchus proposed a land reform: return to the poor the public lands seized by the rich. He was killed by a mob of senators right on the forum (133 BC). His brother Gaius met the same fate (121 BC).
The philosophical cause
Polybius — Polybius had already written it: Rome's mixed constitution is ideal, but wealth will destroy it. The Gracchi saw this before anyone else.
A precedent was set: a political opponent can be killed. Ninety years later Caesar will cross the Rubicon; a hundred and ten years later the Republic will be gone.
Stoicism comes to Rome
Greek philosophers — Panaetius, Posidonius — bring Stoicism to Rome. It becomes the philosophy of the Roman elite: duty, moderation, service to the state.
The philosophical cause
Rome is rich and anxious. Stoicism offers an answer: the external does not matter; only what is inside you matters.
Cicero, Seneca, Marcus Aurelius — all Stoics. It is through Rome that Stoicism will reach the modern age.
