  • January: The previous opponents of King Friedrich III. from the House of Habsburg and the city of Zurich join forces in the Old Zurich War . Zurich receives a Habsburg captain, Thuringia von Hallwil, to whom the citizens have to take an oath. From now on, the Zurich troops wear the red Habsburg cross, no longer the white federal cross. Although Zurich has the right to conclude such an alliance with the Confederation according to the Federal Letter, the other federal locations demand that the Confederation must be dissolved. Zurich reacts negatively to the invitation to a federal arbitration court in Einsiedeln and invokes its free right of association.
