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.
Rhineland-Palatinate
Adolf Süsterhenn submitted a draft constitution to the Advisory State Assembly, which was passed after several rounds of negotiation on 25 April 1947 in a final vote with the absolute majority of the CDU voting for and the SPD and KPD voting against it. One of the reasons for this was that the draft constitution made provision for separate schools based on Christian denomination. On 18 May 1947, the Constitution for Rhineland-Palatinate was adopted by 53 percent of the electorate in a referendum. While the Catholic north and west of the new state adopted the constitution by a majority, it was rejected by the majority in Rhenish Hesse and the Palatinate. On the same date, the first elections took place for the state parliament, the Landtag of Rhineland-Palatinate. The inaugural assembly of parliament took place on 4 June 1947 in the large city hall at Koblenz. Wilhelm Boden was elected the first minister-president of Rhineland-Palatinate. Just one month later, Peter Altmeier succeeded him.
