Page "Reformation in Switzerland" Paragraph 32

The alliance of 1560 of the Catholic cantons with Savoy encouraged duke Emmanuel Philibert to raise claims on the territories his father Charles III had lost in 1536.

After the treaty of Lausanne of 1564, Bern had to return the Chablais south of Lake Geneva and the Pays de Gex ( between Geneva and Nyon ) to Savoy in 1567, and the Valais returned the territories west of Saint Gingolph two years later in the treaty of Thonon.

Geneva was thus a Protestant enclave within the Catholic territories of Savoy again and as a result intensified its relations with the Swiss confederacy and Bern and Zürich in particular.

Its plea for full acceptance into the confederation — the city was an associate state only — was rejected by the Catholic majority of cantons.
