Protection
The protection of roads and rivers was often a precondition of mobility, but protection could also serve as an excuse for self-interested interference with traffic flows. This was the case on the River Weser, which was contested between the City of Bremen and the counts of Oldenburg. Bremen employed armed vessels to protect the river from privateers but also impeded Oldenburg from levying customs duties, to the point of a virtual ‘toll war’. Bremen also struggled to discipline its soldiers whose exactions sparked the protest of boatmen and the riverine population. The way in which safe conduct justified self-serving economic and political goals—on the Lower Weser as elsewhere—can be understood as a dynamic of ‘securitization’, a process in which an issue is presented as existentially threatened and requiring extraordinary emergency measures. In academic debates, some jurists sublimated these tensions into an exclusionary and selective conception of free movement.
