Vespasian (/vɛˈspeɪʒ(i)ən, -ziən/; Latin: Vespasianus [wɛspasiˈaːnʊs]; 17 November AD 9 – 23/24 June 79) was a Roman emperor who reigned from 69 to 79 AD. The fourth and last emperor who reigned in the Year of the Four Emperors, he founded the Flavian dynasty that ruled the Empire for 27 years. His fiscal reforms and consolidation of the empire generated political stability and a vast Roman building program.
Vespasian was the first emperor from an equestrian family and only rose into the senatorial rank as the first member of his family later in his lifetime. Vespasian's renown came from his military success; he was legate of Legio II Augusta during the Roman invasion of Britain in 43 and subjugated Judaea during the Jewish rebellion of 66.
