The French invasion of Switzerland (German: Franzoseneinfall) occurred from January to May 1798 as part of the French Revolutionary Wars. The independent Old Swiss Confederacy collapsed from the invasion and simultaneous internal revolts called the "Helvetic Revolution". The Swiss ancien régime institutions were abolished and replaced by the centralised Helvetic Republic, one of the sister republics of the French First Republic.
