Publius Cornelius Tacitus, known simply as Tacitus ( TAS-it-əs, Latin: [ˈtakɪtʊs]; c. AD 56 – c. 120), was a Roman historian and politician. Tacitus is widely regarded as one of the greatest Roman historians by modern scholars. The surviving portions of his two major works—the Annals (Latin: Annales) and the Histories (Latin: Historiae)—examine the reigns of the emperors Tiberius, Claudius, Nero, and those who reigned in the Year of the Four Emperors (69 AD).
