In Verrem is the work written by Cicero in 70 BC against Gaius Verres, governor of Sicily from 73 to 71 BC, accused of extortion.
Called into question by the Sicilians themselves, who were tired of the abuse and suppression of the praetor, the orator maximus, with only his first two speeches, featuring logical arguments and evidence, convinced Verres into voluntary exile. This, however, did not prevent Cicero from writing five more speeches, which he never gave.
