From the 19th century to Present:
The Princes of Leiningen
In 1779 Count Karl Friedrich Wilhelm of Leiningen-Dagsburg-Hardenburg was raised into an Imperial princely rank. But the new Princedom Leiningen with its seat in Bad Dürkheim was destined to be there only for a short period of time. In 1794, Napoleon Bonaparte’s troops marched into Palatinate because of the French Revolution and destroyed the Castle of Bad Dürkheim to the ground.
In 1803, the princes (which were forced to take refuge) were compensated for their losts of property and goods on the left side of the Rhine. They took over the allocated territory and the princes started to reorganize the administration of the former imperial principalities Palatinate, Mainz and also the Bishopric of Würzburg at once. The reorganization of the upper administration-, justice and forestry offices were very successful. The other institutions remained the way they were. The reformatory efforts which began in 1805 were never executed because of the Rhine Alliance formed on the 12th July 1806 by the French sovereign and 16 German princes. The File of the alliance brought the end to the souvereignty of the Princedom Leiningen. This happened to the benefit of the Granddukedom Baden, which received all rights of sovereignty. In the treaty of the 8th September 1810 Baden assigned the former properties and offices of Leiningen to the Granddukedom Hessen-Darmstadt. After that only a few properties and offices were left in Hessen. The rest moved to Bavaria in 1816.
The former Principality lost most of its political power. But the polity of law and order was left there until 1848. The princely house was also engaged in topics of educational and cultural issues, road construction and the improvement of the infrastructure.
Queen Victoria (halfsister of Prince Karl of Leiningen, first President of the Paulskirchenkabinett, the First German Parliament)
also supported the work of the family with significant charitable institutions.
In the 20th century the princely family was still engaged in a lot of topics. For example, the establishment of a museum of local history, the renovation of the baroque monastery and the Stauffer castle Wildenburg, the rebuilding of the burned down Latin school and the promotion of tourism in the region.
