The Julio-Claudians and the Flavians

Because the principate was not technically an office, Augustus could not legally hand it to a successor. There were various plots surrounding the succession, including the one for which Ovid was banished. Augustus dealt firmly with plotters, sometimes having them executed, and he also found a way to solve the succession issue. Just as his great-uncle Julius Caesar had adopted him, he adopted his stepson Tiberius (who was also his son-in-law) as his son. Adoption of an heir was a common practice among members of the elite in Rome, who used this method to pass on property to a chosen younger man — often a relative — if they had no sons. Long before Augustus’s death he shared his consular and tribunician powers with Tiberius, thus grooming him for the principate. In his will Augustus left most of his vast fortune to Tiberius, and the Senate formally requested Tiberius to assume the burdens of the principate. Formalities apart, by the time of his death in 14 C.E. Augustus had succeeded in creating a dynasty.

For fifty years after Augustus’s death the dynasty that he established — known as the Julio-Claudians because all were members of the Julian and Claudian clans — provided the emperors of Rome. Two of the Julio-Claudians who followed Augustus, Tiberius and Claudius, were sound rulers and able administrators. The other two, Caligula and Nero, were weak and frivolous men who exercised their power poorly and to the detriment of the empire.

Augustus’s creation of an imperial bodyguard known as the Praetorians (pree-TAWR-ee-uhnz) had repercussions for his successors. In 41 C.E. the Praetorians murdered Caligula and forced the Senate to ratify their choice of Claudius as emperor. The events were repeated frequently. During the first three centuries of the empire, the Praetorian Guard all too often murdered emperors they were supposed to protect, and raised to emperor men of their own choosing.

In his early years Nero ruled fairly well, but he became increasingly paranoid about the power of those around him. In 68 C.E. his erratic actions and his policies led to a revolt by several generals, which was supported by the Praetorian Guard and members of the Senate. He was declared an enemy of the people and committed suicide. This opened the way to widespread disruption and civil war. In 69 C.E., the “year of the four emperors,” four men claimed the position of emperor in quick succession. Roman armies in Gaul, on the Rhine, and in the east marched on Rome to make their commanders emperor. The man who emerged triumphant was Vespasian, commander of the eastern armies.

Vespasian restored the discipline of the armies. To prevent others from claiming the throne, Vespasian designated his sons Titus and Domitian as his successors, thus establishing the Flavian dynasty. Although Roman policy was to rule by peaceful domination whenever possible, he used the army to suppress the rebellions that had begun erupting at the end of Nero’s reign. The most famous of these was one that had burst out in Judaea in 66 C.E., sparked by long-standing popular unrest over taxes. Jewish rebels initially defeated the Roman troops stationed in Judaea, but a larger army under the leadership of Vespasian and his son Titus put down the revolt. They destroyed much of the city of Jerusalem, including the Jewish temple, in 70 C.E., and took thousands of Jews as military captives and slaves, dispersing them throughout the empire. The military conquest of Judaea represented a failure of official Roman policy, but it is a good example of the way in which the Romans maintained clear control over their subjects, a control backed by military force if initial attempts at negotiation failed.

The Flavians carried on Augustus’s work in Italy and on the frontiers. During the brief reign of Vespasian’s son Titus, Mount Vesuvius in southern Italy erupted, destroying Pompeii and other cities and killing thousands of people. (See “Individuals in Society: Pliny the Elder.”) Titus gave money and sent officials to organize the relief effort. His younger brother Domitian, who followed him as emperor, won additional territory in Germany, consolidating it into two new provinces. Later in life he became more autocratic, however, and he was killed in 96 C.E. in a plot that involved his own wife, ending the Flavian dynasty.
