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 eventually to the formation of the Swiss canton of Graubünden. Most of the lands of Graubünden were part of the Roman province Raetia in 15 BC. The area later was part of the lands of the Bishopric of Chur.

On January 29, 1367, the League of God's House (German: Gotteshausbund, Italian: Lega Caddea, Romansh:  Lia da la Chadé ), was founded to resist the rising power of the Bishopric of Chur and the House of Habsburg. Bishop Peter Gelyto reacted by transferring the bishopric to the Habsburgs in exchange for a pension from the ducal house.

The instrument of union was signed by envoys of the cathedral chapter, the episcopal Ministerialis, the city of Chur and the districts of Domleschg, Schams, Oberhalbstein, Oberengadin, Unterengadin and Bergell. Other districts joined the league subsequently, including the Poschiavo in 1408 and the Vier Dörfer in 1450.
