Tiberius in Wikipedia

Tiberius Julius Caesar Augustus (November 16, 42 BC – March 16, AD 37), born Tiberius Claudius Nero, 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 his father and was remarried to 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 somber ruler who never really desired to be emperor; Pliny the Elder called him tristissimus hominum, "the gloomiest of men."[1] After the death of Tiberius’ son Drusus Julius Caesar in 23, the quality of his rule declined and ended in a terror. In 26, Tiberius exiled himself from Rome and left administration largely in the hands of his unscrupulous Praetorian Prefects Sejanus and Macro. Caligula, Tiberius' grand-nephew and adopted grandson, succeeded the emperor upon his death...
