Vespasian (/vɛsˈpeɪʒ(i)ən, -ziən/; Latin: Vespasianus [wɛspasjˈaːnus]; 17 November AD 9 – 23 June 79) was Roman emperor from 69 to 79. The last emperor to reign in the Year of the Four Emperors, he founded the Flavian dynasty, which ruled the empire for 27 years. His fiscal reforms and consolidation of the empire brought political stability, enabling an extensive program of public works.
Vespasian was the first emperor from an equestrian family who rose only later in his lifetime into the senatorial rank as the first of his family to do so. He rose to prominence through military achievement: he served as legate of Legio II Augusta during the Roman invasion of Britain in 43, and later led the Roman forces in the Jewish rebellion of 66–70.
