Following a revolt in Judaea in A.D. 66, Nero gave Vespasian a special commission to take care ot it. Following the suicide of Nero, Vespasian swore allegiance to his successors, but then revolted with the governor of Syria in spring of 69. He left the siege of Jerusalem to Titus. On December 20, Vespasian arrived in Rome and Vitellius was dead. Vespasian launched a building plan and restoration of the city of Rome at a time when its wealth had been delpleted by civil wars and irresponsible leadership. Vespasian reckoned that he needed 40 billion sesterces. He inflated the currency and increased provincial taxation. He also gave money to insolvent senators so they could keep their positions.
Vespasian died of natural causes on June 23, A.D. 79.
