This book, written by Sallust revolves around the Catilinarian conspiracy, which was an attempted coup d'état by Lucius Sergius Catiline to overthrow the consuls of 63 BC Marcus Tullius Cicero and Gaius Antonius Hybrida and forcibly assume control of the state in their stead. The conspiracy was formed after Catiline's defeat in the consular elections for 62 BC. He assembled a coalition of malcontents aristocrats who had been denied political advancement by the voters, dispossessed farmers, and indebted Sullan veterans and planned to seize the consulship from Cicero and Antonius by force. Cicero later exposed the conspiracy and Catiline fled from Rome to join his army in Etruria. The next month, Cicero uncovered nine more conspirators organizing for Catiline in the city and, on advice of the senate, had them executed without trial.
