Who is Vespasian from The Jewish War and what is their importance?

Vespasian was the name of the Roman general and subsequent Emperor who was also the father of Titus. Early in his military career Vespasian's troops captured Josephus and planned to send him to Nero. Josephus prophesied that the Roman commander would become Emperor. Consequently Vespasian initially protected Josephus by keeping him from Nero. Later Vespasian rewarded Josephus with his former house in Rome, pension for life and Roman citizenship. Vespasian's first attack on Jerusalem was interrupted by his call to Rome as emperor. The second, final invasion was led by his son Titus despite multiple offers of Roman clemency to the Jews according to Josephus. Nero was anxious about happenings in Judea so he sent Vespasian to take command of the armies in Syria.
