Titus Caesar Vespasianus (30 December 39 – 13 September 81 AD) was Roman emperor from 79 to 81 AD. A member of the Flavian dynasty, Titus succeeded his father Vespasian upon his death, becoming the first Roman emperor ever to succeed his biological father.
Before becoming emperor, Titus gained renown as a military commander, serving under his father in Judea during the First Jewish–Roman War. The campaign came to a brief halt with the death of emperor Nero in 68 AD, launching Vespasian's bid for the imperial power during the Year of the Four Emperors. When Vespasian was declared Emperor on 1 July 69 AD, Titus was left in charge of ending the Jewish rebellion. In 70 AD, he besieged and captured Jerusalem, and destroyed the city and the Second Temple. For this achievement Titus was awarded a triumph; the Arch of Titus commemorates his victory and still stands today.
During his father's rule, Titus gained notoriety in Rome serving as prefect of the Praetorian Guard, and for carrying on a controversial relationship with the Jewish queen Berenice.
