The Grey League was founded through the alliance of 21 communities from the "Vorderrhein" and "Hinterrhein" valleys in the Alps. On February 14, 1395, the three main nobles (the abbot of Disentis, Johannes von Ilanz, Baron Ulrich II von Rhäzüns and Baron Albert von Sax-Misox) of the "Vorderrhein" together with delegates from the Court Municipalities in Ilanz created an "eternal alliance". Since the alliance was predominantly located in the high country, it was also known as "Part Sura" ( or High Alliance). Five days later, Count Johann von Werdenberg-Sargans joined the League at Flimserwald.
