context_page_description: Tiberius was the second Roman Emperor. He ruled from 14 to 37 AD. He was the step-son of Caesar Augustus.
  Tiberius was one of Ancient Rome's greatest generals, whose campaigns protected the northern frontier. He reigned for 22 years, and the first part of his imperial work was excellent. Later, he came to be remembered as a dark, reclusive, and somber ruler. After the death of his son Drusus in 23, the quality of his rule declined and ended in terror.
  In 26, Tiberius moved from Rome to the Isle of Capri, and left administration largely in the hands of his unscrupulous Praetorian Prefect Sejanus. Sejanus became the effective ruler of Rome, and plotted against Tiberius, murdering people who opposed him. When alerted, Tiberius counter-plotted to remove Sejanus from his official positions, and eventually executed him. More executions followed of people who had committed crimes under Sejanus' rule.
  Caligula, Tiberius' grand-nephew and adopted grandson, succeeded the Emperor upon his death.
context_section_description: Sejanus had served the imperial family for almost twenty years when he became Praetorian Prefect in AD 15. The death of Drusus elevated Sejanus. Tiberius had statues of Sejanus erected throughout the city, and Sejanus became more and more visible as Tiberius began to withdraw from Rome altogether. Finally, with Tiberius's withdrawal to Capri in AD 26, Sejanus was left in charge of the entire state mechanism and the city of Rome.
  Sejanus's position was not quite that of successor. The presence of Livia (the third wife and advisor of Augustus) seems to have checked his power for a time. Her death in AD 29 changed all that. Sejanus began a series of purge trials of Senators in Rome. Germanicus's widow Agrippina the Elder and two of her sons were arrested and exiled in AD 30 and later all died in suspicious circumstances.
  In response, Tiberius manoeuvered cleverly. He knew an immediate condemnation of Sejanus might not succeed. Since he and Sejanus were then joint Consuls, Tiberius resigned his post of Consul, which forced Sejanus to do likewise. This removed much of Sejanus' legal powers and protection. Then, in AD 31, Sejanus was summoned to a meeting of the Senate, where a letter from Tiberius was read condemning Sejanus and ordering his immediate execution. Macro was appointed Praetorian Prefect, with the specific job of removing Sejanus. Sejanus was tried, and he and several of his colleagues were executed within the week.
  More treason trials followed. Tacitus writes that Tiberius had been hesitant to act at the start of his reign, but now, towards the end of his life, he seemed to do so without compunction. However, Tacitus' portrayal of a tyrannical, vengeful emperor has been challenged by several modern historians. The prominent ancient historian Edward Togo Salmon notes in his work, A history of the Roman world from 30 B.C. to A.D. 138:
  "In the whole twenty two years of Tiberius' reign, not more than fifty-two persons were accused of treason, of whom almost half escaped conviction, while the four innocent people to be condemned fell victims to the excessive zeal of the Senate, not to the Emperor's tyranny".
