Drusus Julius Caesar
Problems arose quickly for the new Princeps. The Roman legions posted in Pannonia and Germania had not been paid the bonuses promised them by Augustus, and after a short period of time mutinied when it was clear that a response from Tiberius was not forthcoming. Germanicus and Tiberius's son, Drusus Julius Caesar, were dispatched with a small force to quell the uprising and bring the legions back in line.
