The market of Riegersburg was founded as market around 1140/50 by the sovereign of that time, Margrave Otakar III. Around 1530 only a dozen of craftsmen (cobblers, tailors, weavers, millers) and their families lived in the approximately 15 bourgeois houses “Unndterm Stain zu Rögkherspurg” – that is how the market was called back then. Because nearly all trades were represented in Feldbach and Fürstenfeld, the capacity of the market of Riegersburg always remained quite moderate. When Maria Theresia turned the market into the seat of an administrative district in 1770, which included at first 12 and later on even 18 taxing districts, the place reobtained a central administrative organisation. Since the introduction of municipal self-administration in the year 1850 parish councils and since 1918 mayors manage the fate of the market.
