Swiss Federal Charter
Uri, Schwyz and Unterwalden swear mutual aid
In early August 1291 three forest communities by Lake Lucerne formed a "perpetual alliance" of mutual aid against outside threats, above all the Habsburgs. The charter later came to be seen as the founding of Switzerland, and 1 August is its national day.
