Political Factionalism and Crisis in Late Republican Rome: 62 BC

Opposition to Cicero and the Rise of Metellus Nepos. The political aftermath of the Catilinarian conspiracy initiated a wave of severe attacks against Cicero, whose extrajudicial executions of the conspirators drew immediate legislative backlash. On 10 December 63 BC, new tribunes of the plebs entered office, notably Quintus Metellus Nepos, whose radical reputation had previously impelled Marcus Porcius Cato to seek the tribunate as a counterweight. Metellus Nepos launched systematic denunciations targeting Cicero's unauthorized punishment of Roman citizens. On the final day of December, as outgoing consuls traditionally delivered valedictory speeches detailing their accomplishments, Nepos alongside his colleague Lucius Bestia executed a tribunician veto (intercessio) preventing Cicero from speaking—an exceptional political insult. Denied his speech, Cicero utilized the obligatory consular oath to swear that he had saved the Roman Republic. Serving as Pompey the Great's brother-in-law and former legate in the East, Metellus Nepos returned to Rome as an explicit champion of the general's interests, amid intense debate over how the victorious commander should re-enter Italian politics to resolve remaining insurrections.

Legislative Maneuvering and Praetorian Attacks. On 1 January 62 BC, Gaius Julius Caesar assumed the office of praetor and immediately initiated legislative attacks against the conservative leader Quintus Lutatius Catulus. Focusing on the restoration of the Temple of Jupiter Optimus Maximus on the Capitoline Hill—destroyed by fire in 83 BC and entrusted to Catulus during his consulship in 78 BC—Caesar summoned Catulus before the public assembly in the Forum to answer for alleged financial embezzlement and delayed execution. In a deliberate breach of aristocratic protocol, Caesar barred the ex-consul from speaking from the elevated Rostra, forcing him to defend himself from ground level. Caesar submitted a bill to strip Catulus of the commission and transfer the architectural completion to Pompey, aligning himself publicly with the popular general to cultivate political support (popularis strategy). Strong resistance from conservative optimates ultimately forced Caesar to abandon the measure, highlighting his tendency to prioritize public alignment over legislative victory.

Escalation to Civil Unrest and the Senatus Consultum Ultimum. Caesar Subsequently aligned with Metellus Nepos, who promulgated a bill to recall Pompey and his legions to restore public order in Italy and extinguish Catiline's insurgent forces. Cato fiercely opposed the bill in the Senate, vowing to prevent Pompey's armed entry into Rome. On the voting day, Nepos convened an assembly at the Temple of Castor and Pollux, utilizing its elevated platform in the eastern Forum as a substitute for the Rostra, with Caesar sitting beside him in institutional support. The platform was secured by armed supporters and gladiators. When Cato and his fellow tribune Quintus Minucius Thermus mounted the podium to interpose their veto, Cato sat directly between Nepos and Caesar. As the clerk prepared to read the bill, Cato exercised his tribunician veto; when Nepos attempted to read the text himself, Cato snatched the document, prompting Thermus to physically gag Nepos. The tribune signaled his armed retainers, initiating a severe riot involving improvised weapons and blades.

The Senate's Emergency Decree and the Flight of Nepos. Suspension and Restoration of Caesar. Following the violent disruption, Cato was physically shielded by the consul Lucius Licinius Murena, and the crowd was dispersed. That afternoon, the Senate convened and passed the emergency decree (senatus consultum ultimum). Although a proposal to strip Nepos of his tribunate was dropped at Cato's own insistence, Nepos summoned a final assembly accusing the Senate of conspiring against Pompey, before fleeing the city to join Pompey in Rhodes—an explicit breach of the law forbidding tribunes from leaving Rome overnight. Concurrently, the Senate suspended Caesar from his praetorship due to his support of Nepos. Caesar initially resisted by maintaining his official regalia, but to avert armed conflict, he dismissed his six lictors carrying the fasces (symbols of executive imperium), laid aside his toga praetexta, and retired to the domus publica. When a loyal crowd assembled to forcibly reinstate him, Caesar managed the crowd, successfully de-escalating the crisis and convincing the Senate to reinstate his praetorian powers.

Final Suppression of the Catilinarian Conspiracy and Informer Trials. In the field, Catiline's rebel army was defeated by forces nominally commanded by Gaius Antonius Hybrida, though led on the field by his legate Marcus Petreius. Despite Cato's assertions that decisive action would break the rebels' morale, the main body of insurgents refused surrender and died in battle alongside Catiline, whose end drew aristocratic respect. In Rome, political paranoia led to widespread denunciations incentivized by state rewards. The restored senator Quintus Curius accused Caesar of complicity in the conspiracy, while an equestrian named Lucius Vettius claimed to possess an incriminating letter written by Caesar to Catiline. Appearing before the Senate, Caesar appealed directly to Cicero, who verified that Caesar had voluntarily provided intelligence regarding the plot, thereby stripping Curius of his reward. Acting in his capacity as praetor, Caesar ordered Vettius brought before the Rostra, where he was severely beaten and imprisoned, effectively halting further judicial accusations against Caesar.
