Catilinarian conspiracy

63–62 BCE · 1st century BCE · Also known as Second Catilinarian conspiracy, Conspiracy of Catiline

The Catilinarian conspiracy was a plot by the Roman aristocrat Lucius Sergius Catilina (Catiline) and his associates to seize power in Rome in 63 BCE, after he had again failed to win election as consul. Exposed by the consul Cicero, whose four speeches against Catiline became classics of Latin oratory, the conspiracy collapsed: Catiline left the city to join a rebel army in Etruria, and five conspirators arrested in Rome were executed without trial after a debate in the Senate. Catiline was killed when his army was destroyed near Pistoria early in 62 BCE.
