    Cantonal deputies proclaimed the Helvetic Republic as a unified state on April 12, 1798.

Background and detail

Background. The Swiss Confederacy had previously consisted of self-governing cantons united by a loose military alliance. French Republican armies enveloped Switzerland under the pretext of liberating the Swiss people from a feudal system. This military pressure led to the complete overrun of the country by French troops in March 1798, causing the Old Swiss Confederation to collapse.

Proclamation. On April 12, 1798, 121 cantonal deputies formally proclaimed the Helvetic Republic, declaring it "One and Indivisible." This event marked the creation of a centralized government in Switzerland, replacing the previous loose alliance of cantons. The new republic was established as a sister republic of France during the French Revolutionary Wars.
