Palatine Lion
After the Second World War the Palatinate Lion re-emerged as the regional symbol of the Palatinate, for example, on postage stamps in the French Zone of Occupation. Following the creation of the state of Rhineland-Palatinate in 1946, to which the Palatinate belonged, the Palatine Lion occupied a central place in the state coat of arms of Rhineland-Palatinate. The other elements of the Rhineland-Palatine coat of arms are the Wheel of Mainz ("Mainzer Rad") and the Cross of Trier ("Trierer Kreuz"). Even the semi-official coat of arms of the Province of Palatinate, which existed from 1946 to 1968 and dated to the 19th century, bore the Palatine Lion, which after the inclusion of the former territories of Electoral Mainz and Electoral Trier, symbolised the region of the present-day Palatinate.
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.
