Northern Italy provided access to the vulnerable southern borders of both
France and
Austria, making
Milan and the
Duchy of Savoy essential to their security. In 1631, France annexed
Pinerolo in
Piedmont and occupied
Casale Monferrato, while much of their territory was on the northern side of the
Alps in modern
France. As a result, most viewed Savoy as a French
satellite state. During the 1688-89
Nine Years' War between France and the
Grand Alliance, Savoy held the key to France's vulnerable southern borders. This concern was heightened by an ongoing Huguenot
Camisard revolt in the south west, while the Allies began recruiting support among the
Waldensians, a Protestant sect in the Swiss
Canton of Vaud, persecuted by both Savoy and France. By summer 1690, it was clear that Savoy could not avoid involvement on one side or the other.
Victor Amadeus II ultimately decided in favour of the Alliance, hoping to regain Pinerolo and Casale, which controlled access to his capital,
Turin. Defeated by the French at
Staffarda in August 1690, his duchy was only saved by receiving reinforcements from Spain,
Bavaria and
Brandenburg-Prussia. In 1692, Victor Amadeus made a short-lived invasion of the
Dauphiné, but the war was financially crippling for participants. Crop failures in France and northern Italy between 1693 and 1695, widespread famine was caused, with Piedmont being one of the worst affected areas. , whose recovery was a primary objective for Savoy. In October 1693, Victor Amadeus was defeated at
Marsaglia, while
Leopold I now claimed Casale as an Imperial possession. This meant replacing the French would not benefit Savoy, and in November 1694, Victor Amadeus intensified informal talks with Louis XIV. In early 1695, France secretly agreed to surrender Casale if its defences were destroyed, and in July Victor Amadeus took possession. With the Allies increasingly suspicious, treaty negotiations were conducted in secret between the
Comte de Tessé and Savoy's senior diplomat, the Marquis de St-Thomas. ==Provisions==
