Three Leagues
From Wikipedia, the free encyclopedia
The Three Leagues was the alliance of 1471 of the League of God's House, the League of the Ten Jurisdictions and the Grey League, leading to the formation of the Swiss canton of Graubünden. The Three Leagues became allied with the Old Swiss Confederacy in 1496[citation needed], siding with it in the Swabian war of 1499, but they did not join the Confederacy until the imposition of the Helvetic Republic in 1803.
