Victor Amadeus I, Duke of Savoy
Victor Amadeus became Duke of Savoy after his father's death in 1630. Charles Emmanuel's policies had brought a great instability in the relationships with both France and Spain, and troops were needed to defend the Duchy. As money was lacking to recruit mercenaries or train indigenous soldiers, Victor Amadeus signed a peace treaty with Spain. With the Treaty of Cherasco, Savoy was given back Pinerolo, although, according to a secret point of the agreement, that important stronghold was to remain with France in exchange for Geneve.
