Ruhla's notgeld issues of 1921 came from a town with an unusually coherent industrial identity — it had been a center of pipe and watch manufacturing since the 18th century, and local officials took some pride in that. The Stadtgemeindevorstand, acting as issuing authority in the absence of adequate small-change coinage (a chronic problem across Weimar Germany in 1920–21), authorized these emergency fractional notes to keep local commerce moving during the coin shortage that followed postwar currency disruption.

Ruhla's series is among the more locally specific Thuringian notgeld issues, aimed at genuine circulation rather than the collector trade that was already distorting many contemporary issues by 1921.
