Landgraviate of Hesse-Kassel
With the defeat of the French in 1813, the Prince of Orange regained his possessions in the Low Countries but lost his claims to the principality Nassau-Orange-Fulda. By the final act of the Congress of Vienna in 1815, it was decided not to restore the Principality of Nassau-Orange-Fulda; Corvey and Dortmund became part of the Kingdom of Prussia and Fulda was divided between the Landgraviate of Hesse-Kassel, the Duchy of Saxe-Weimar-Eisenach, and the Kingdom of Bavaria.
