Nero Claudius Drusus Germanicus (January 14, 38 BC – 9 BC) was born as Decimus Claudius Drusus and was the wife of Augustus, Livia, also known as Drusus, Drusus I, Drusus Claudius Nero or Elder Drusus, the first husband of Tiberius Claudius Nero ‘ is the youngest son and the famous Roman general.
Drusus married Marcus Antonius and Little Antonia, the daughter of Augustus’s sister, Little Octavia, and the loyalty to her became quite famous. Their children are Germanicus, Livilla, Emperor Claudius and the other (at least) who died in childhood. Antonia, who lived for at least fifty years after the death of Drusus, never married again.
Augustus bestowed several titles on his stepchildren. In 19 BC, Drusus had the authority to legally acquire all official duties for five years in order to receive these duties. When Tiberius left Italy as praetor in 16 BC, Drusus replaced him. The following year he took the title quaestor and fought against the Rhaetian bandits in the Alps. Drusus did not able to crush his powers completely, but he wanted a reinforce from Tiberius. The two siblings brought together these Alpine locals easily. In 13 BC, Drusus was sent to Gallia to suppress the rebellion, which was caused by the former ruler. While there, Germen ties crossing the border attacked Roman settlements. By driving the Drusus Legions, the Germans drove behind the Rhine. The Germans entered the depths of their land, reached as far as the North Sea, and attached the annual favors to the Frisians. As a reward, Drusus was made praetor urbanus for 11 years BC.
Drusus did not stay in Rome when he received his title. Once again Baharda headed towards the German border. Again he drove the Germen tribes to the inside until winter stopped him. Although he was attacked on his way back to Rome, Germen succeeded in breaking his forces. It was proclaimed Emperor by their troops. In the year 10 BC, the Chatti tribe attacked the camp of Drusus in unison with the Sicambrians, but they were easily misled. Drusus then went to Lugdunum to meet Augustus and Tiberius (where Claudius was born) and returned to Rome with them. In 9 BC, the council was easily chosen but left the city without undertaking the task once again. Once again after the Chatti had been brought up, this time it was back to the palace against the Marcomanni, but then returned to the Rhine river. Drusus, the result of complications that resulted in falling attenuation, died four months after the accident, where Tiberius joined him. Suetonius tells us that he rejected the offer to return to Rome shortly after his death. Drusus’s body was brought back and his ashes were placed in the “Augustus Mozelesi”. On his behalf Moguntiacum (modern Mainz) became famous with his legions who dictated a monument.  The family was rewarded with the title “Germanicus”, an inheritance and an honorary title passed from father to son. Although Augustus wrote a biography on his behalf, the work did not arrive on a daily basis.
Problem of fatherhood
There are speculations about who Drusus’ father is, and some claim he is Augustus’s own son. This claim, however, has not been widely respected by modern historians because Augustus never accepts that he is his son, nor does he attempt to adopt any adoption. Julia, the eldest daughter of Augustus’s only child, Scribonia. He gave birth to five grandchildren (3 boys, 2 girls) who would take Augustus to all of them. After the death of the two grandsons and the sending of the third to exile, Augustus never acted to adopt the sons of Drusus, Germanicus and Claudius.
Another theory is that Augustus and Livia have been married for 51 years but have never had children since they got married. Perhaps they were successful in making children from other people whom they had previously married, but they both had difficulty in making children together. Ultimately, Augustus did not recognize Livia at the time he was pregnant with Drusus, which meant that he could not father a child from him.
