"My name is Tiberius Julius Caesar Augustus[b] (/taɪˈbɪəriəs/, ty-BEER-ee-əs; 16 November 42 BC – 16 March AD 37) I was Roman emperor from AD 14 until 37. I succeeded my own stepfather Augustus, the first Roman emperor. I was born in Rome in 42 BC to Roman politician Tiberius Claudius Nero and his wife, Livia Drusilla. In 38 BC, my mother divorced my father and married Augustus. Following the untimely deaths of Augustus' two grandsons and adopted heirs, Gaius and Lucius Caesar, I was designated Augustus' successor. Prior to this, I had proved myself an able diplomat, and one of the most successful Roman generals: my conquests of Pannonia, Dalmatia, Raetia, and (temporarily) parts of Germania laid the foundations for the empire's northern frontier."
