'The Catiline Conspiracy' is a history book published by the Roman historian Sallust. The second historical monograph in Latin literature, it chronicles the attempted overthrow of the government by the aristocrat Catiline in 63 BC in what has been usually called the Catilinarian conspiracy. The narrative of the monograph was seized upon as illustrating the moral and social decadence of the ruling Roman classes, particularly the Roman Senate. Sallust continually critiques Roman corruption throughout his narration.
