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.
Middle Rhine
The Allied forces ended hostilities of the Second World War on the Middle Rhine on 19 March 1945. The French again took up the administration of the territory in its occupation zone. At end of 1946, the Americans created the State Hesse in their occupation zone; six months later the French founded of the State of Rhineland-Palatinate. Although some areas were combined in the new states that historically do not belong together, a sense of togetherness quickly appeared. The desire for state boundaries more in line with historical territorial boundaries, however, never ceased entirely.
