"Histories" (Historiae) is a history, written c. 100–110, which originally covered the Year of Four Emperors in Rome following the downfall of Nero, the rise of Vespasian, and the rule of the Flavian Dynasty (69–96) up to the death of Domitian. In June 68, the emperor Nero was deposed in favour of the elderly general Galba, and committed suicide. Beginning in January 69, Tacitus tells the story of the Year of Four Emperors, as Galba was overthrown by Otho, Otho by Vitellius, and finally, Vitellius by Vespasian.
Of the approximately fourteen books originally included in the work, only five books survive. The later books, which originally covered the majority of Vespasian's reign and those of his sons Titus and Domitian, have not survived.
