Tiberius was born on 16 November 42 BC. His mother Livia Drusilla married for the second time and became Octavian’s wife in 38 BC. Consequently, the future Emperor Augustus was Tiberius’ stepfather. Octavian enabled him to have an excellent and extensive education and introduced him to politics. Tiberius entered into a career as a military officer, holding different military posts. In 13 BC he became consul for the first time, along with Publius Quintilius Varus.
The Emperor Augustus sent Tiberius to the northern provinces in order to secure the border along the Danube. In 8 BC he moved towards the north and subdued the Germanic tribes between the rivers Rhine and Elbe. He resettled about 40 000 Sicambri and Suebi in the areas near the Rhine.
When Agrippa’s sons Caius and Lucius died - the destined successors to the Emperor –Tiberius was adopted by his stepfather Augustus. Following his request Tiberius had to simultaneously adopt Germanicus, although he already had a son by birth. Further successful military missions were carried out in Germania. Tiberius reached the rivers Elbe and Weser.
Tiberius needed to intervene in the conflict with Marbod’s Marcomanni in Bohemia and in the outbreak of the uprising in Pannonia. He concluded a peace agreement with Marbod. The rebellion in Pannonia required a great deal of effort and was finally crushed by deploying 15 legions. After Varus’ defeat in 9 AD however he resumed power in the Rhine area. Together with Germanicus, he went back to Germania in the following year where subsequent fights took place. In 12 AD Tiberius was allowed to celebrate his Pannonian triumph.
In 14 AD Tiberius assisted the Emperor Augustus in conducting a census. He was preparing himself to go to Illyria when he heard of the Emperor’s death. He succeeded him on 19 August 14 AD.
