Gaius Sallustius Crispus, usually anglicised as Sallust, was a historian and politician of the Roman Republic from a plebeian family. Probably born at Amiternum in the country of the Sabines, Sallust became a partisan of Julius Caesar, circa 50s BC. He is the earliest known Latin-language Roman historian with surviving works to his name, of which Conspiracy of Catiline on the eponymous conspiracy, The Jugurthine War on the eponymous war, and the Histories remain extant. As a writer, Sallust was primarily influenced by the works of the 5th-century BC Greek historian Thucydides. During his political career he amassed great and ill-gotten wealth from his governorship of Africa.
