Disentis Abbey, founded in ca. 720, was already in early medieval times the cultural and political center of the later Grisons. Situated on the road to the Lukmanier pass used by the German emperors on their way to Italy, Disentis became a place of international importance in the high Middle Ages and the prince abbot of Disentis was the lord of the Rhine valley. In the later Middle Ages, the farmer communities in the valleys became stronger and the influence of the monastery decreased, but the abbot of Disentis still played an important role in the founding of the Grey League in 1395.
