Despite initial concerns over his character, Titus ruled to great acclaim following the death of Vespasian on June 23, 79, and was considered a good emperor by Suetonius and other contemporary historians. In this role he is best known for his public building program in Rome, and completing the construction of the Colosseum in 80, but also for his generosity in relieving the suffering caused by two disasters, the Mount Vesuvius eruption of 79, and the fire of Rome of 80. Titus continued his father's efforts to promote the Flavian dynasty. He revived practice of the imperial cult, deified his father, and laid foundations for what would later become the Temple of Vespasian and Titus, which was finished by Domitian. After barely two years in office, Titus unexpectedly died of a fever on September 13, 81, and was deified by the Roman Senate.
