The Freiämtersturm in December 1830 was a bloodless revolution in the Swiss canton of Aargau. The dissatisfied rural population of the Freie Ämter region in Aargau marched on the cantonal capital of Aarau to demand changes in the cantonal constitution. The Freiämtersturm, together with other uprisings in 1830–31 led to the end of the Restoration period and the beginning of the liberal Regeneration period. The changes during the Regeneration led to the creation of the Federal State in 1848.
