Tiberius ((ラテン語:Tiberius Caesar Dīvī Augustī Fīlius Augustus);〔Classical Latin spelling and reconstructed Classical Latin pronunciation of the names of Tiberius:
〕〔Tiberius' regal name has an equivalent English meaning of "Tiberius Caesar, Son of the Divine Augustus, the Emperor".〕 16 November 42 BC – 16 March 37 AD) was a Roman Emperor from 14 AD to 37 AD. Born Tiberius Claudius Nero, a Claudian, Tiberius was the son of Tiberius Claudius Nero and Livia Drusilla. His mother divorced Nero and married Octavian, later known as Augustus, in 39 BC, making him a step-son of Octavian.
Tiberius would later marry Augustus' daughter (from his marriage to Scribonia), Julia the Elder, 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 following thirty years; historians have named it the Julio-Claudian dynasty. In relations to the other emperors of this dynasty, Tiberius was the stepson of Augustus, grand-uncle of Caligula, paternal uncle of Claudius, and great-grand uncle of Nero.
Tiberius was one of Rome's greatest generals; his conquest of Pannonia, Dalmatia, Raetia, and temporarily, parts of Germania, laid 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."〔Pliny the Elder, ''Natural Histories'' (XXVIII.5.23 ); Capes, (p. 71 )〕
After the death of Tiberius’ son Drusus Julius Caesar in 23 AD, he became more reclusive and aloof. In 26 AD Tiberius removed 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 Tiberius upon his death.〔(【引用サイトリンク】url=http://www.pbs.org/empires/romans/empire/tiberius.html )〕
