Second Catilinarian conspiracy

The second Catilinarian conspiracy, also known simply as the Catiline conspiracy, was a plot, devised by Catiline with the help of a group of aristocrats and disaffected veterans, to overthrow the Roman Republic. In 63 BC, Cicero exposed the plot which forced Catiline to flee from Rome.

Composition of the conspiracy


Catiline began to attach many other men of senatorial and equestrian rank to his conspiracy, and like him many of the other leading conspirators had faced similar political problems in the Senate. Publius Cornelius Lentulus Sura, the most influential conspirator after Catiline, had held the rank of consul in 71 BC, but he had been cast out of the senate by the censors during a political purge in the following year on the pretext of debauchery. Publius Autronius Paetus was also complicit in their plot, since he was banned from holding office in the Roman government. Another leading conspirator, Lucius Cassius Longinus who was praetor in 66 BC with Cicero, joined the conspiracy after he failed to obtain the consulship in 64 BC along with Catiline. By the time that the election came around, he was no longer even regarded as a viable candidate. Gaius Cethegus, a relatively young man at the time of the conspiracy, was noted for his violent nature. His impatience for rapid political advancement may account for his involvement in the conspiracy. The ranks of the conspirators included a variety of other patricians and plebeians who had been cast out of the political system for various reasons. Many of them sought the restoration of their status as senators and their lost political power.

Promoting his policy of debt relief, Catiline initially also rallied many of the poor to his banner along with a large portion of Sulla’s veterans. Debt had never been greater than in 63 BC since the previous decades of war had led to an era of economic downturn across the Italian countryside. Numerous plebeian farmers lost their farms and were forced to move to the city, where they swelled the numbers of the urban poor. Sulla's veterans were in bad economic straits as well. Desiring to regain their fortunes, they were prepared to march to war under the banner of the "next" Sulla. Thus, many of the plebs eagerly flocked to Catiline and supported him in the hope of the absolution of their debts.

Course of the conspiracy
Catiline sent Gaius Manlius, a centurion from Sulla’s old army, to manage the conspiracy in Etruria where he assembled an army. Others were sent to aid the conspiracy in important locations throughout Italy, and even a small slave revolt which had begun in Capua. While civil unrest was felt throughout the countryside, Catiline made the final preparations for the conspiracy in Rome. Their plans included arson and the murder of a large portion of the senators, after which they would join up with Manlius’ army. Finally, they would return to Rome and take control of the government. To set the plan in motion, Gaius Cornelius and Lucius Vargunteius were to assassinate Cicero early in the morning on November 7, 63 BC, but Quintus Curius, a senator, who would eventually become one of Cicero's chief informants warned Cicero of the threat through his mistress Fulvia. Fortunately for Cicero, he escaped death that morning by placing guards at the entrance of his house who scared the conspirators away.

On the following day, Cicero convened the Senate in the Temple of Jupiter Stator and surrounded it with armed guards. Much to his surprise, Catiline was in attendance while Cicero denounced him before the Senate; however, the senators adjacent to Catiline slowly moved away from him during the course of the speech, the first of Cicero's four Catiline Orations. Incensed at these accusations, Catiline exhorted the Senate to recall the history of his family and how it had served the republic, instructing them not to believe false rumors and to trust the name of his family. He finally accused them of placing their faith in a "homo novus", Cicero, over a "nobilis", himself. Supposedly, Catiline violently concluded that he would put out his own fire with the general destruction of all. Immediately afterward, he rushed home and the same night ostensibly complied with Cicero's demand and fled Rome under the pretext that he was going into voluntary exile at Massilia because of his "mistreatment" by the consul; however, he arrived at Manlius’ camp in Etruria to further his designs of revolution.

While Catiline was preparing the army, the conspirators continued with their plans. The conspirators observed that a delegation from the Allobroges was in Rome seeking relief from the oppression of its governor. So, Lentulus Sura instructed Publius Umbrenus, a businessman with dealings in Gaul, to offer to free them of their miseries and to throw off the heavy yoke of their governor. He brought Publius Gabinius Capito, a leading conspirator of the equestrian rank, to meet them and the conspiracy was revealed to the Allobroges. The envoys quickly took advantage of this opportunity and informed Cicero who then instructed the envoys to get tangible proof of the conspiracy. Five of the leading conspirators wrote letters to the Allobroges so that the envoys could show their people that there was hope in a real conspiracy. However, a trap had been laid. These letters were intercepted in transit to Gaul at the Mulvian Bridge. Then, Cicero had the incriminating letters read before the Senate the following day, and shortly thereafter these five conspirators were condemned to death without a trial despite an eloquent protest by Julius Caesar. Fearing that other conspirators might try to free Lentulus and the rest, Cicero had them strangled in the Tullianum immediately. He even escorted Lentulus to the Tullianum personally. After the executions, he announced to a crowd gathering in the Forum what had occurred. Thus, an end was made to the conspiracy in Rome.
