Nero Claudius Drusus was the son of Livia and the senator Tiberius Claudius Nero. Before he was born his parents divorced so that Augustus could marry his mother. Unlike his older brother, the future emperor Tiberius whom Augustus disliked, the emperor doted on his younger stepson. In 13 BC Drusus was sent to govern Gaul, and while there he repelled an attack by a tribe of Germans who had invaded the province. Most of the following years until his death were spent on campaigns in German territory. First, he crossed the Rhine frontier and penetrated as far as the North Sea, subduing the Frisii. The following years saw him engaged against various confederations of the Chatti, Sicambri and Marcomanni. He died tragically in 9 BC from injuries he sustained when he fell from his horse while on campaign fighting the Marcomanni.
The Arch of Drusus that appears on the reverse of this coin and which commemorated his campaigns in Germania has not survived. Its precise location is not known.
The Arch of Drusus is an ancient arch in Rome, Italy, close to the First Mile of the Appian Way and next to the Porta San Sebastiano. Long misidentified, it is most likely the remains of the Arch of Trajan.
The exact origins of the current Arch are disputed. It is now generally agreed that it has nothing to do with Nero Claudius Drusus, the conqueror of the Germans. The original Arch of Drusus was erected by the Senate in honour of Drusus following his death in 9 BCE, and spanned the Via Appia. Its exact location is not certain, but this arch no longer exists.
