Titus, (40?–81 A.D.), a Roman emperor. His full name was Titus Flavius Sabinus Vespasianus; he was the son of Vespasian. He accompanied his father, then a general, to Palestine after the Jewish revolt broke out in 66. Titus was left in charge of the Roman forces in 69 when Vespasian returned to Rome because of the death of the emperor Nero. Having been elected emperor, Vespasian ordered his son to press for victory. Jerusalem fell before Titus' attack in 70, and the young general was received in Rome as a triumphant hero.
Titus served as co-ruler with his father and upon his death in 79 became emperor, but reigned only two years before his own death. Titus' brother, Domitian, succeeded as emperor. Domitian erected the Arch of Titus in Rome as a memorial of his brother's and father's victories over the Jews.
