Number of foreign subjects enserfed by the Electors Palatine in 1665. The map shows that the spatial extent of the Palatine incursions in the neighboring territories were much more limited than previously assumed (the light grey area).
The elevation profile of the region shows that most of the serfs lived in the Rhine Rift Valley and in Rhenish Hesse, areas with fertile soils and a warm climate. The villages in these areas were easily accessible and more densely populated, offering a larger tax base.
