Background and detail

Background. The Helvetic Republic, established after the 1798 French invasion, replaced the decentralized Old Swiss Confederation with a centralized government. Instability peaked in 1802, culminating in the Stecklikrieg civil war following the withdrawal of French troops. A draft constitution was defeated in a popular vote in June 1802, leading to rural revolt against the Republic.

Mediation Process. Napoleon acted as a mediator, convening representatives of Swiss cantons in Paris to end the conflict. The Act of Mediation was an attempt to compromise between the Ancien Régime and a republic. In the preamble, Napoleon declared the natural political state of the Swiss was a federation, explaining his role as a mediator.

New Cantons. The Act admitted Graubünden, St. Gallen, Thurgau, Ticino, and Vaud as cantons. St. Gallen and Graubünden were formerly associates, while the others were subject lands conquered at various times. The Act aimed to address issues that tore the Republic apart, providing a framework for a new confederation under French influence.
