During the French Revolutionary Wars, the revolutionary armies marched eastward, enveloping Switzerland in their battles against Austria. In 1798, Switzerland was completely overrun by the French and was renamed the Helvetic Republic. The Helvetic Republic encountered severe economic and political problems. In 1798 the country became a battlefield of the Revolutionary Wars, culminating in the Battles of Zürich in 1799.
In 1803 Napoleon's Act of Mediation reestablished a Swiss Confederation that partially restored the sovereignty of the cantons, and the former tributary and allied territories of Aargau, Thurgau, Graubünden, St. Gallen, Vaud and Ticino became cantons with equal rights.
The Congress of Vienna of 1815 fully re-established Swiss independence and the European powers agreed to permanently recognise Swiss neutrality. At this time, the territory of Switzerland was increased for the last time, by the new cantons of Valais, Neuchâtel and Geneva.
The Restoration, the time leading up to the Sonderbundskrieg, was marked with turmoil, and the rural population struggling against the yoke of the urban centres, for example in the Züriputsch of 1839.
