After Francesco Gonzaga's death in 1612, Savoy renewed its claims on Montferrat and invaded (1613) the region. Spain and France intervened.
The Treaty of Cherasco (1631) assigned parts of Montferrat to the house of Savoy, and the rest (including Casale) followed the fortunes of the duchy of Mantua and passed to the Nevers (French) branch of the Gonzaga family. All of Montferrat was recognized by the Peace of Viena (1708) as belonging to the house of Savoy.
