The choice of the first Flavian emperor, Vespasian, was made by the soldiers and presented to a willing senate. Vespasian had made a name for himself in his military career, which included the first Jewish War and siege of Jerusalem, in which his older son, Titus, participated.
Silver Age Latin literature flourished under the first two Flavian emperors.
