Also in 1586, a Catholic "coup d'état" in Mulhouse, an associate of the confederacy, prompted the military intervention of the Protestant cantons, which quickly restored the old Protestant order. Strasbourg, another Protestant city, wanted to join the confederacy in 1588, but like Geneva some twenty years earlier, it was rejected by the Catholic cantons. In the Valais, the Reformation had had some success especially in the lower part of the Rhône valley. However, in 1603 the Catholic cantons intervened, and with their support re-Catholicisation succeeded and the Protestant families had to emigrate.
