Rhineland-Palatinate
Rhineland-Palatinate was established in 1946 after World War II from territory of the historically separate regions of the Free State of Prussia, People's State of Hesse, and Bavaria, by the French military administration in Allied-occupied Germany. Rhineland-Palatinate became part of the Federal Republic of Germany in 1949, and shared the country's only border with the Saar Protectorate until it was returned to German control in 1957. Rhineland-Palatinate has since developed its own identity built on its natural and cultural heritage, including the extensive Palatinate winegrowing region, its picturesque landscapes, and many castles and palaces.
North Rhine
It was formed on 5 June 1945 on the basis of the Berlin Declaration and the resulting creation of occupation zones for the victors of World War II out of the administrative regions ("Regierungsbezirke") of Aachen, Düsseldorf and Cologne, which were all part of Prussia's Rhine Province. The southern part of Rhine province, consisting of the administrative regions of Koblenz and Trier became part of the French occupation zone on 5 June 1945. The division of the Rhineland, which had been united in 1815 by the Congress of Vienna under the Prussian crown, was thus pre-destined to be split between different governments and administrations - from summer 1946 into the states of North Rhine-Westphalia and Rhineland-Palatinate. Rhine Province existed until 20 October 1946. On that day the government formed in August 1946 for the state of North Rhine-Westphalia dissolved the upper councils of the provinces of North Rhine and Westphalia on the instructions of the British occupying power.
