Josephus was a Jew who became a leader in the Jewish rebellion of AD 69. He was captured and ended up working for the Romans as a slave translator during the siege of Jerusalem. After being defeated and humiliated by initial Jewish victories, the Romans had called old General Vespasian out of retirement to lead the army that crushed Judea. While the siege of Jerusalem was going on, word came from Rome that the Praetorian Guard had arranged a new vacancy in Rome (Emperor Vitellius had been murdered after 8 months of rule), and they wanted Vespasian to come to Rome and become Emperor. Vespasian left his son Titus in charge. Titus befriended Josephus.
