The idea of the charter of 1291 representing the founding document of the Confederacy was first suggested in a report by the Federal Department of Home Affairs of 21 November 1889, in the context of a proposed combined celebration of the 700th anniversary of the foundation of Bern and the 600th anniversary of the Confederacy in 1891. Celebration of a national holiday on 1 August based on the date on the document was first suggested in 1899 (although it was introduced officially only in 1994).
