Quick questions on Tiberius AD 14 to 37: HSC Ancient History Section IV

Tiberius maintained Augustus's frontier policy. He continued the imperial bureaucratic system. He showed financial discipline.

Tiberius's adopted nephew, the popular general Germanicus, conducted military operations on the Rhine (AD 14-16). Germanicus's death in Syria (AD 19) under suspicious circumstances became the central rumor of the early reign.

Tiberius's natural son Drusus died in AD 23 (later attributed to poisoning by Sejanus, possibly false).

Sejanus concentrated the Praetorian Guard in Rome (in barracks at the Castra Praetoria, AD 23). He systematically eliminated rivals through trials and judicial murder. He sought to marry Tiberius's daughter-in-law Livilla.

Tiberius retired to Capri in AD 26 and ruled by letter through Sejanus.

Tiberius, possibly alerted by Antonia (Drusus's wife), wrote a verbose denouncing letter to the Senate. Sejanus was arrested at the Senate, executed the same day. The aftermath included widespread proscriptions of Sejanus's allies and family.

Tacitus's Annals presents the trials as Tiberius's vehicle for political revenge against the senatorial class.

Note that Augustus had also used maiestas trials, and that the scale under Tiberius is contested. The emperor's role was sometimes oppressive, sometimes restrained.

Hostile portrait. Tiberius as concealed tyrant. The Annals's first six books are the major source.

Anecdotal, retains the rumors of Capri excesses.

Tiberius's reign was administratively successful (continued Augustan frontier policy, financial discipline) but politically dark (treason trials, Capri seclusion). The blackest period (Sejanus and his aftermath) was substantially due to the structural problems of the Principate, not solely to Tiberius's character.
