In 1813, the inhabitants of Pyrmont began to protest at their lack of autonomy within Waldeck–Pyrmont and the separate constitutional nature of the two territories was confirmed the following year, until a formal union was established in 1849.
1813. aastal hakkasid Pyrmonti elanikud protestima autonoomia puudumise pärast Waldeck-Pyrmontis ja järgmisel aastal kinnitati kahe territooriumi eraldi põhiseaduslik loomus, kuni 1849. aastal formaalne unioon loodi.
