In April of 56 BC, Julius Caesar met Marcus Licinius Crassus at Ravenna and Pompey the Great at Luca, modern Lucca in Tuscany, and the three men renewed the First Triumvirate by dividing up Rome's consulships and armies for the next five years.

By the spring of 56 the alliance was close to breaking. Publius Clodius Pulcher's street gangs had made Pompey afraid to walk through Rome, Pompey believed Crassus was backing a plot against his life, and Cicero, just back from exile, moved to reopen Caesar's land law of 59. Lucius Domitius Ahenobarbus was running for the consulship of 55 on a promise to take Caesar's legions away. Caesar couldn't enter Rome without losing his command, so he stayed inside his province and invited his partners north. Plutarch and Appian say more than 200 senators followed them there, though those numbers may be exaggerated, and Cicero, our only witness from the time, describes them as two separate meetings.

Over the next year Rome made the deal legal. Cicero gave his speech On the Consular Provinces arguing that Caesar should keep Gaul, the Senate voted to pay Caesar's legions, Pompey and Crassus were elected consuls for 55 under an interrex, the Lex Trebonia gave them Spain and Syria for five years, and the Lex Pompeia Licinia extended Caesar's command by five more. I follow Ronald Syme in reading Luca as the moment Rome's biggest decisions moved outside its institutions, and I give Erich Gruen's case against that reading too, so you can weigh them yourself.

Julius Caesar broke the Roman Republic years before he crossed the Rubicon, and this episode follows how he did it, from his birth in 100 BC through the consulship of 59 BC and the conquest of Gaul to the deadline of 50 BC.

Caesar came from one of Rome's oldest patrician families and had almost no money. He survived Sulla's proscriptions after refusing to divorce Cornelia, the daughter of Cinna, borrowed his way up the ladder of offices, and won the election for Pontifex Maximus in 63 BC on debts that would have ended his career if he had lost. Marcus Crassus guaranteed his loans so he could leave for Spain.

As consul in 59 BC, Caesar passed his land law over the obstruction of his colleague Marcus Calpurnius Bibulus, who had dung dumped over his head in the Forum and then shut himself in his house for the rest of the year, announcing that he was watching the skies. Caesar ignored him. That year showed that the Republic's lawful brakes only worked if the man being stopped agreed to stop, and it left Caesar open to prosecution the moment he became a private citizen again.

The Lex Vatinia gave him a five-year command in Cisalpine Gaul and Illyricum, and the Senate added Transalpine Gaul. Over the next nine years he fought the Helvetii, Ariovistus, the Belgae, and the Veneti, bridged the Rhine, crossed to Britain twice, and defeated Vercingetorix at the siege of Alesia in 52 BC. The war gave him an army loyal to him, a fortune he used to put senators in his debt, and his own account of the war, the Commentaries on the Gallic War, written in the third person for voters back in Rome.

By 50 BC the Republic had no safe way to make Caesar a private citizen again. I lean on Caesar's own account through much of this episode because it's often all we have, so I'd encourage you to read the Gallic War yourself and keep asking what he wanted his readers to believe.

Pompey could have been Caesar. He chose the Republic, and the Republic destroyed him. Every structural ingredient Caesar would later use to end the Roman Republic, Pompey had first. He refused to use them. That refusal is what killed him.

In 62 BC, Gnaeus Pompeius Magnus landed at Brindisium with the largest Roman army any general had commanded in a generation. He had just spent four years reorganizing the entire eastern Mediterranean world, ending Mithridates, annexing Syria, taking Jerusalem, raising Rome's annual revenue by nearly 70%. He had 40,000 veterans who followed him personally. He had a network of client kings whose crowns had come from his hand. Everyone in Italy expected him to march on Rome.

He disbanded his army on the beach.

He walked into Rome as a private citizen and asked the Senate for two things, both of them legal. Ratify his eastern settlement. Give his veterans the land they had been promised. The Senate refused both for three years. Cato blocked him on principle. Lucullus blocked him out of jealousy. Crassus blocked him out of rivalry. The most constitutional man in Rome had done the constitutional thing, and the Republic responded by proving it could not process him.

That is the moment the Republic ended. Not at the Rubicon. Not at Pharsalus. In the Senate chamber between 61 and 60 BC, when the system refused to reward the one man who still played by its rules.

Everything after that was mechanical. Pompey joined Caesar and Crassus in the First Triumvirate because the Senate had closed the legal route. Caesar built his own personal army in Gaul while Pompey atrophied in Rome. Julia died. Crassus died. The alliance dissolved. And when Caesar crossed the Rubicon in 49 BC, Pompey ran, because the man who had once held the greatest command in Roman history had forgotten how to use it.

He was murdered on a beach in Egypt on September 28, 48 BC, the day before his 58th birthday, by a former Roman officer who had served under him in the pirate campaign fourteen years earlier.

The counterfactual: in 62 BC, Pompey could still have been constitutional. By 49 BC, Caesar could not be. Individual virtue matters, but only inside the window the structure allows. Pompey is the case that proves it.

This is Episode 129 of The Roman Pattern.
