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 ( or ); the name Rhineland-Palatinate () was first confirmed in the constitution of 18 May 1947. The provisional French government at that time wanted originally to leave the option open of annexing further areas west of the Rhine after the Saarland was turned into a protectorate. When the Americans and British, however, had led the way with the establishment of German states, the French came under increasing pressure and eventually followed their example by setting up the states of Baden, Württemberg-Hohenzollern, and Rhineland-Palatinate. However, the French military government forbade the Saarland from joining Rhineland-Palatinate. Mainz was named as the state capital in the regulation; the "Mixed Commission" (), named as the highest organ of state charged with the administration of the new state and with the preparation of an advisory state assembly, started its work in Mainz. However, war damage and destruction meant that Mainz did not have enough administrative buildings, so the headquarters of the state government and parliament was provisionally established in Koblenz. On 22 November 1946, the constituent meeting of the Advisory State Assembly () took place there, and a draft constitution was drawn up. Previously, local elections had been held. Wilhelm Boden was (after a short term of office as the of Rhineland-Hesse-Nassau) nominated on 2 December as the minister president of the new state by the French military government. Early years Adolf Süsterhenn submitted to the Advisory State Assembly a draft constitution, 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. A point of contention involved the draft constitution providing for separate schools based on Christian denomination. On 18 May 1947 53% of the electorate adopted the Constitution for Rhineland-Palatinate in a referendum. While the Catholic north and west of the new state adopted the constitution by a majority, the majority in Rhenish Hesse and the Palatinate voted against. On the same
