Territory of Monferrato

The Gonzaga Nevers, were the direct successors of the branch of the Gonzaga family, and that is to say: Charles I (1631-1637), Charles II (1637-1665) and Ferdinando Carlo (1665-1707) ruled so bad the remaining territory of Monferrato. Ferdinand Carlo, last and worst of the Dukes of Mantova and Monferrato, sold in 1681 to Louis XIV the citadel of Casale, mighty fortress that gave the Bourbons a solid point of support in the fight against the Habsburgs of Spain and Austria in Italy. During the war of the League of Augusta, Casale was taken off to France from the Austro-Savoy weapons (1695), and returned to Ferdinando Carlo, after having demolished its fortifications. A few years later, at the beginning of the succession war of Spain, the same Ferdinando Carlo delivered his state to the French (1701).
  
Carlo Ferdinando was declared guilty of treason by the emperor, his feudal ruler, and stripped of his states and human rights, Mantova fell under the empire, and Monferrato, after the victory of Turin, was finally assigned to Vittorio Amedeo II (1708) . The treaties of Utrecht (1713) and Rastadt (1714) finally confirmed the allocation of Monferrato to the House of Savoy. Since then, the history of the marquisate is confused with that of Piemonte.
