History Ilanz is first mentioned in 765 as "Iliande." Ilanz became the capital of the newly formed Grey League in 1395. The Grey League was the second of the Three Leagues which eventually formed canton Graubünden. Johannes von Ilanz, the Abbot of Disentis, was among the three nobles instrumental in creating this "eternal alliance." Ilanz has a special place in the history of the Protestant Reformation. In the 1520s, the Diet of Ilanz declared that citizens of the Three Leagues should be free to choose between Catholicism and the Protestant forms of Christianity then rising to the fore. These and other events resulted in a counter-reformation within the Swiss Confederation that reversed many of the gains of the Reformation in Switzerland.
