 What had begun as a local conflict over the control of the Val Müstair and the Umbrail Pass in the Grisons soon got out of hand when both parties called upon their allies for help; the Habsburgs demanding the support of the Swabian League, and the Federation of the Three Leagues of the Grisons turning to the Swiss "Eidgenossenschaft".
