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.
Erdesbach
With the founding of the Kingdom of Bavaria after French times in 1816, Erdesbach belonged to the "Bürgermeisteramt" (“Mayoralty”) of Ulmet, the "Landcommissariat" (later "Bezirksamt", then "Landkreis", or rural district) of Kusel and the "bayerischer Rheinkreis", the part of the kingdom that was not contiguous with the rest to the east. The kingdom's borders, as defined by the Congress of Vienna, remained thus until 1945 (by which time the monarchy had ended and Bavaria was now the Free State of Bavaria). With the formation of the new state of Rhineland-Palatinate in 1947, consisting of the "Regierungsbezirke" of Koblenz, Trier, Montabaur, Rheinhessen and Pfalz, a new political order was created in the southwest of what was shortly to become West Germany. Later, the "Regierungsbezirke" of Montabaur and Rheinhessen were dissolved and integrated into the "Regierungsbezirke" of Koblenz and Pfalz respectively; in 2000, all the state's "Regierungsbezirke" were dissolved, and in their stead arose the "Aufsichts- und Dienstleistungsdirektion" (ADD. roughly “Directorate of Inspection and Services”), which is now responsible for the whole of Rhineland-Palatinate.
