The book presents two works of the Roman historian Sallust describing two important events of
his time: the Jugurthine War and the Catilinarian conspiracy. The Jugurthine War was a conflict
between the Roman Republic and Numidia a kingdom on the north African coast approximating
modern Algeria. The Catilinarian conspiracy was a plot devised by Catiline with the help of a
group of aristocrats and disaffected veterans to overthrow the Roman Republic in 63 BC.
