Rhineland-Palatinate
The state of Rhineland-Palatinate was founded shortly after the Second World War on 30 August 1946. It was formed mainly from the southern part of the Prussian Rhine Province (the "Regierungsbezirke" of Koblenz and Trier), from Rhenish Hesse, from the western part of Nassau and the Bavarian Rhenish Palatinate minus the county of Saarpfalz. The Joint German-Luxembourg Sovereign Region ("Gemeinschaftliches deutsch-luxemburgisches Hoheitsgebiet") is the only unincorporated area of the state of Rhineland-Palatinate. This condominium is formed by the rivers Moselle, Sauer, and Our, where they run along the border between Luxembourg and Rhineland-Palatinate or the Saarland.
Nannhausen
In 1399, Nannhausen had its first documentary mention in a document from Count Johann IV of Sponheim. Nannhausen belonged to the Ravengiersburg Monastery and in 1557, in the wake of the Reformation, passed to the Duchy of Palatinate-Simmern. At first, the village was Lutheran, but then later it became Reformed. Once the Dukes of Palatinate-Simmern had died out in 1673, the village passed to Electoral Palatinate, and in 1686, it was no longer forbidden to practise the Catholic faith. Beginning in 1794, Nannhausen lay under French rule. In 1814 it was assigned to the Kingdom of Prussia at the Congress of Vienna. After being under French occupation again after each of the world wars, it became part of the then newly founded state of Rhineland-Palatinate in 1946. The current municipality came into being on 17 March 1974 through the merger of the municipalities of Nannhausen and Nickweiler.
