Rhineland-Palatinate
The state of Rhineland-Palatinate was founded shortly after the Second World War on 30 August 1946. It was formed mainly from the southern part of the Prussian Rhine Province (the "Regierungsbezirke" of Koblenz and Trier), from Rhenish Hesse, from the western part of Nassau and the Bavarian Rhenish Palatinate minus the county of Saarpfalz. The Joint German-Luxembourg Sovereign Region ("Gemeinschaftliches deutsch-luxemburgisches Hoheitsgebiet") is the only unincorporated area of the state of Rhineland-Palatinate. This condominium is formed by the rivers Moselle, Sauer, and Our, where they run along the border between Luxembourg and Rhineland-Palatinate or the Saarland.
Wolfstein, Rhineland-Palatinate
After the new post-Napoleonic order imposed by the Congress of Vienna in 1814, Wolfsteiners became Bavarian nationals, which until 1918 meant the Bavarian king’s subjects; after monarchy was overthrown in 1918, they belonged to the Free State of Bavaria in the days of the Weimar Republic. Only in 1947, after the Second World War, did the Palatinate formally cease to be a Bavarian exclave, whereupon it was incorporated into the then newly founded state of Rhineland-Palatinate. The break with Bavaria was confirmed by referendum on 22 April 1956.
