This historical map of Germany, focused on the Peace of Westphalia (1648), illustrates the territorial and political settlements that ended the Thirty Years’ War. The use of color is key to the map’s meaning: different shades represent the territorial acquisitions and confirmed sovereignties of the various European states and imperial territories following the peace negotiations.
The map highlights one of the most significant outcomes of the treaty system: the fragmentation and redistribution of authority within the Holy Roman Empire. In the Alsace (Elsass) region, France is shown acquiring the Landgraviates of Upper and Lower Alsace, as well as the Landvogtei (imperial bailiwick) over the Ten Imperial Cities and their associated dependencies. This marks an important westward expansion of French influence and a weakening of direct imperial control in the Upper Rhine region.
In northern Germany, particularly around Osnabrück, the map reflects the complex ecclesiastical and political arrangements established by the peace settlement. The House of Brunswick-Lüneburg (later connected to the Electorate of Hanover) is depicted as gaining alternating rights of appointment to the bishopric of Osnabrück, a compromise arrangement designed to balance Catholic and Protestant interests within the Empire.
Overall, the map serves both as a geographical representation and a political document, visualizing the constitutional restructuring of Central Europe after 1648. It emphasizes the decentralized nature of the post-war Holy Roman Empire, where sovereignty was increasingly divided among territorial princes, free cities, and external powers like France and Sweden.
