"Conspiracy of Catiline and the Jurgurthine War" by Sallust is a pair of historical monographs published around 41-40 BC. These works examine two pivotal conflicts in Roman history: Catiline's conspiracy of 63-62 BC and the Jugurthine War of 112-106 BC. Sallust argues that both episodes reveal a deeper crisis—the corruption and moral decline of the Roman Republic. Through portraits of ambitious leaders and compromised officials, he explores how bribery and political decay threatened Rome's stability and virtue. (This is an automatically generated summary.)
