Germania Inferior and Germania Superior, along the Rhine, and neighbouring Raetia were provinces inherited by Hadrian which lacked major external threats and had the potential to become flourishing parts of the Roman Empire. Relying on his personal knowledge of the regional situation he strengthened civilian self-government by gradually reducing the role of the military. Apart from the legions, all other units were stationed in a small defined cordon at the edge of Roman territory. Together with the now well-dated building of the palisade as a continuous running barrier, Hadrian's initiatives might be seen as an imperial gift to the provincials.
