League of God's House in the context of "Grey League"

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.

The League of the Ten Jurisdictions was the last of the Three Leagues founded during the Middle Ages in what is now Canton Graubünden of Switzerland. The League was created in the County of Toggenburg after the counts of Toggenburg died out. The League initially existed to resist the power of the House of Habsburg, and quickly allied with the Grey League and the League of God's House. In 1524 the three leagues joined to become the Free State of the Three Leagues, which existed until the Napoleonic dissolution of the Free State. The league was an associate and ally of the Old Swiss Confederacy.

The Prince-Bishopric of Chur (German: Hochstift Chur, Fürstbistum Chur, Bistum Chur) was an ecclesiastical principality of the Holy Roman Empire, and had Imperial immediacy. The Prince-Bishopric of Chur controlled contiguous land from the city of Chur, to Engadin, and to Vinschgau. The historical State must be distinguished from the Roman Catholic Diocese of Chur which still exists, even if the bishop was the same man.

They were led by the League of God's House from the 15th century. The Three Leagues then took over any effective power from the Prince-Bishopric (while in Vinschgau the control passed to the Habsburg), and after the Reformation the bishop's estates remained the sole territory of the principality. The bishop had the vote number 51 in the Imperial Diet.
