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.
Fritz Neumayer
After World War II, Neumayer joined the newly founded liberal party of the western occupation zones, the Free Democratic Party (FDP). Also in 1945, he became president of the state court in Kaiserslautern. He was elected to the advisory state board of the newly founded state of Rhineland-Palatinate in 1946, and to the respective state parliament in 1947. When Rhineland-Palatinate became a constituent state of the Federal Republic of Germany in 1949, Neumayer was elected to the federal parliament, where his primary concern was ensuring the independence of judges from the state.
