Title:
Switzerland

Context:
When war broke out between France and its rivals, Russian and Austrian forces invaded Switzerland. The Swiss refused to fight alongside the French in the name of the Helvetic Republic. In 1803 Napoleon organised a meeting of the leading Swiss politicians from both sides in Paris. The result was the Act of Mediation which largely restored Swiss autonomy and introduced a Confederation of 19 cantons. Henceforth, much of Swiss politics would concern balancing the cantons' tradition of self-rule with the need for a central government.

Question:
What was the Act of Mediation responsible for restoring?

Swiss autonomy
