三同盟自由州

The Three Leagues, sometimes referred to as Raetia, was the 1471 alliance between the League of God's House, the League of the Ten Jurisdictions, and the Grey League. Its members were all associates of the Old Swiss Confederacy, and as such enjoyed positive relations with the Confederation, which eventually led to the formation of the Swiss canton of Grisons.

The territory corresponds to the core territory of Raetia Curiensis (ruled by the bishops of Chur as Prince-Bishopric of Chur), the early medieval remnant of the Roman province of Raetia prima.
