Rhineland-Palatinate
On 10 July 1945 the occupation authority on the soil of the present-day Rhineland-Palatinate transferred from the Americans to the French. To begin with, the French divided the region provisionally into two "upper presidiums" ("Oberpräsidien"), Rhineland-Hesse-Nassau (for the hitherto Prussian government districts and regions of Koblenz, Trier, and Montabaur) and Hesse-Palatinate (for the hitherto Bavarian Palatinate and old Hessian-Darmstadt province of Rhenish Hesse). The formation of the state was ordained on 30 August 1946, the last state in the Western Zone of Occupation to be established, by Regulation No. 57 of the French military government under General Marie-Pierre Kœnig. It was initially called Rhenish-Palatinate ("Rheinpfälzisches Land" or "Land Rheinpfalz"); the name Rhineland-Palatinate ("Rheinland-Pfalz") was first confirmed in the constitution of 18 May 1947.
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.
