The gens Livia was an illustrious plebeian family at ancient Rome. The first of the Livii to obtain the consulship was Marcus Livius Denter in 302 BC, and from his time the Livii supplied the Republic with eight consuls, two censors, a dictator, and a master of the horse. Members of the gens were honoured with three triumphs. In the reign of Augustus, Livia Drusilla was Roman empress, and her son was the emperor Tiberius.

Tiberius Julius Caesar Augustus was Roman emperor from AD 14 until 37. He succeeded his stepfather Augustus, the first Roman emperor. Tiberius was born in Rome in 42 BC to Roman politician Tiberius Claudius Nero and his wife, Livia Drusilla. In 38 BC, Tiberius' mother divorced his father and married Augustus. Following the untimely deaths of Augustus' two grandsons and adopted heirs, Gaius and Lucius Caesar, Tiberius was designated Augustus' successor. Prior to this, Tiberius had proved himself an able diplomat, and one of the most successful Roman generals: his conquests of Pannonia, Dalmatia, Raetia, and (temporarily) parts of Germania laid the foundations for the empire's northern frontier.
