Bad Wildungen, a spa town in Hesse-Nassau, issued its own emergency currency — Notgeld — during the hyperinflationary collapse of 1923, when the Reichsmark's purchasing power was evaporating fast enough to make million-mark denominations a practical necessity rather than an abstraction. Municipal and local authorities across Germany were effectively forced into printing their own money as the central supply of legal tender failed to keep pace with demand.

The DeNG 7/8 reference places this within the documented corpus of German Notgeld issues, catalogued by district. Spa municipalities like Bad Wildungen typically had smaller print runs than industrial centers, which affects survivorship.
