Vespasian [SEP] Introduction
While Vespasian besieged Jerusalem during the Jewish rebellion, emperor Nero committed suicide and plunged Rome into a year of civil war known as the Year of the Four Emperors. After Galba and Otho perished in quick succession, Vitellius became emperor in April 69. The Roman legions of Roman Egypt and Judaea reacted by declaring Vespasian, their commander, emperor on 1 July 69. In his bid for imperial power, Vespasian joined forces with Mucianus, the governor of Syria, and Primus, a general in Pannonia, leaving his son Titus to command the besieging forces at Jerusalem. Primus and Mucianus led the Flavian forces against Vitellius, while Vespasian took control of Egypt.
