6. Marius and Sulla

Core Argument

The defeat of the Gracchan movement left the Roman ruling class incapable of governing through its old institutions. The senatorial and equestrian orders were locked in conflict, particularly over control of the courts, which determined who could prosecute provincial governors for extortion—a matter of fundamental interest to the publicani drawn from the equites. With neither class able to win decisively, the state apparatus, especially the army, began to rise above society. Gaius Marius’s military reforms of 107 BC transformed the army from a citizen militia into a professional standing army. By opening recruitment to the non-propertied classes, abolishing property distinctions for service branches, and standardising training, he severed the soldier from civil society. Loyalty shifted from the Senate and people to the commander, who guaranteed pay, plunder, and land, laying the basis for Caesarism.

Marius manoeuvred between classes, using the populares and the urban poor to gain power before abandoning them to the aristocracy. The populist leaders Saturninus and Glaucia were massacred by reactionary forces, and a reign of terror united the propertied classes against the poor. Yet the underlying class antagonisms remained unresolved, forcing the state to rely increasingly on military force. The Social War (91–87 BC) erupted when Italian allies, denied Roman citizenship and crushed by debt and land inequality, revolted. The ruling class used the Julian Law and the Lex Plautia Papiria to extend citizenship to non-revolting Italians, dividing the rebellion. The Samnites and Lucanians were crushed by Marius. The war left the treasury drained, the Senate packed with 300 loyal aristocrats, and the voting system weighted toward the propertied classes.

In 88 BC, Sulla led six legions into Rome, the first time the army decided a political struggle. He abolished Sulpician Laws, executed Sulpicius, and banned tribunes from acting without Senate permission. King Mithridates of Pontus invaded Asia and Greece, disrupting the slave supply and causing a severe financial crisis. Cinna, leading the populares, freed slaves, marched on Rome, and unleashed the Marian terror—five days of slaughter against the ruling party. After Marius died, Cinna ruled as dictator, abolished Sulla’s laws, reduced debts by three-quarters, and restored grain distribution. In 83 BC, Sulla landed in Brundisium, bought over opposing armies with gold, and entered Rome as dictator. He instituted a White terror, proscribing at least 4,700 people, confiscating 350 million sesterces, and crushing the Samnites. Sulla established a standing army of 10,000 freed slaves as a bodyguard against citizens, abolished the Gracchan corn dole and equestrian tax-farming system, and attempted to revive small farms through colonisation.

Sulla’s dictatorship concentrated real power in his own hands and the army, not the Senate, despite adding 300 loyal members. He preserved the outward forms of republican democracy while rendering them meaningless. However, his power base, the army, had been transformed: soldiers were loyal only to commanders who guaranteed loot, and six generals had been murdered by their own troops during the civil war. When Sulla ordered Pompey to dismiss his army, Pompey refused; Sulla compromised. He had Quintus Ofella murdered in the marketplace despite having abolished the death penalty for political offences. Sulla’s regime plundered the provinces. War tax on Asia swelled sixfold through usury; provinces faced tithes, land taxes, import duties, forced quartering of troops and officials, and requisitions. Rome’s annual income was only two-thirds of Egypt’s. Slavery reached its heyday, with up to 2 million slaves in Italy—one in three inhabitants. The rich grew fabulously wealthy, flaunting their luxury in defiance of sumptuary laws, while the poor lived in squalid, dangerous slums. Moral decay and the spread of mysticism and superstition accompanied this social breakdown; Sulla himself was superstitious, believing in Fate. The Republic existed in name only, awaiting an executioner.
