Nero Claudius Drusus Germanicus (born 38 bc—died 9 bc), younger brother of Tiberius (who later became emperor) and commander of the Roman forces that occupied the German territory between the Rhine and Elbe rivers from 12 to 9 bc. Drusus was born shortly after the divorce of his mother, Livia Drusilla, from Tiberius Claudius Nero; she immediately married Octavian (later Augustus), who was suspected of being Drusus’ real father. Like his brother, Drusus was allowed to seek office five years before the legally specified age. He became praetor (magistrate) in 11 and consul in 9. With Tiberius he fought against two Alpine tribes (the Raeti and Vindelici), and in 13 he was made governor of the three Gauls. In this office he carried out an important census and erected the altar of Augustus at Lugdunum (now Lyon).
