The 1798 invasion of Switzerland by the French First Republic culminated in the creation of a satellite state called the Helvetic Republic. While the 1798 Swiss constitution and the 1803 Act of Mediation stated that France would protect Swiss independence and neutrality, these promises were not kept. With the latter act, Switzerland signed a defensive alliance treaty with France. During the Restoration, the Swiss Confederation's constitution and the Treaty of Paris's Act on the Neutrality of Switzerland affirmed Swiss neutrality.
