Tiberius Julius Caesar Augustus

Tiberius (pron.: /taɪˈbɪriəs/; Latin: Tiberius Julius Caesar Augustus;[2] 16 November 42 BC – 16 March 37 AD), was Roman Emperor from 14 AD to 37 AD. Tiberius was by birth a Claudian, son of Tiberius Claudius Nero and Livia Drusilla. His mother divorced Nero and married Augustus in 39 BC, making him a step-son of Octavian.

Tiberius would later marry Augustus' daughter Julia the Elder (from his marriage to Scribonia) and even later be adopted by Augustus, by which act he officially became a Julian, bearing the name Tiberius Julius Caesar. The subsequent emperors after Tiberius would continue this blended dynasty of both families for the next forty years; historians have named it the Julio-Claudian dynasty. In relations to the other emperors of this dynasty, Tiberius was the stepson of Augustus, great-uncle of Caligula, paternal uncle of Claudius, and great-great uncle of Nero.

Tiberius was one of Rome's greatest generals, conquering Pannonia, Dalmatia, Raetia, and temporarily Germania; laying the foundations for the northern frontier. But he came to be remembered as a dark, reclusive, and sombre ruler who never really desired to be emperor; Pliny the Elder called him tristissimus hominum, "the gloomiest of men."

After the death of Tiberius’ son Drusus Julius Caesar in 23, he became more reclusive and aloof. In 26, against better judgement, Tiberius exiled himself from Rome and left administration largely in the hands of his unscrupulous Praetorian Prefects Lucius Aelius Sejanus and Quintus Naevius Sutorius Macro. Caligula, Tiberius' grand-nephew and adopted grandson, succeeded the emperor upon his death.

Tiberius was born in Rome on 16 November 42 BC, to Tiberius Claudius Nero and Livia Drusilla. In 39 BC, his mother divorced his biological father and remarried Gaius Julius Caesar Octavianus shortly thereafter, while still pregnant with Tiberius Nero's son. Shortly thereafter in 38 BC his brother, Nero Claudius Drusus, was born.

Little is recorded of Tiberius's early life. In 32 BC, Tiberius made his first public appearance at the age of nine, delivering the eulogy for his biological father. In 29 BC, both he and his brother Drusus rode in the triumphal chariot along with their adoptive father Octavian in celebration of the defeat of Antony and Cleopatra at Actium.

In 23 BC, Emperor Augustus became gravely ill, and his possible death threatened to plunge the Roman world into chaos again. Historians generally agree that it is during this time that the question of Augustus's heir became most acute, and while Augustus had seemed to indicate that Agrippa and Marcellus would carry on his position in the event of his death, the ambiguity of succession became Augustus's chief problem.

In response, a series of potential heirs seem to have been selected, among them Tiberius and his brother, Drusus. In 24 BC, at the age of seventeen, Tiberius entered politics under Augustus's direction, receiving the position of quaestor, and was granted the right to stand for election as praetor and consul five years in advance of the age required by law. Similar provisions were made for Drusus.

Tiberius was married two times, with only his first union proceeding a child who would survive to adulthood:

• Vipsania Agrippina, daughter of Marcus Vipsanius Agrippa (16 BC - 11 BC)
  • Drusus Julius Caesar (13 BC - 23 AD)
• Julia the Elder, only daughter of Augustus (11 BC - 6 BC)
