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.
Mont-Tonnerre
Mont-Tonnerre was a department of the First French Republic and later the First French Empire in present-day Germany. It was named after the highest point in the Palatinate, the "Donnersberg". It was the southernmost of four departments formed in 1798 when the west bank of the Rhine was annexed by France. Prior to the French occupation, its territory was divided between the Archbishopric of Mainz, the Bishopric of Speyer, the Bishopric of Worms, Nassau-Weilburg, Hesse-Darmstadt, the Electorate of the Palatinate and the imperial cities of Worms and Speyer. Its territory is now part of the German states of Rhineland-Palatinate and Saarland. Its capital was Mainz ().
