Saluzzo was a French enclave in the Piedmontese
Alps in the mid-sixteenth century, having been annexed by
Henry II of France following the death of the last marquis
Gian Gabriele I in 1548. France's claim on the marquisate, however, was relatively weak, and in the 1580s its possession of the territory came to be contested by
Charles Emmanuel I, Duke of Savoy, who had begun pursuing a policy of expansion for his duchy and sought to acquire Saluzzo for himself. Taking advantage of the
civil war weakening France during the reign of his cousin
Henry III, Charles Emmanuel occupied Saluzzo in the autumn of 1588, on the pretext of wanting to prevent its occupation at the hands of the
Protestant Huguenots of
Dauphiné, and continued to hold it for the following twelve years. In 1595 the French king
Henry IV, on the occasion of his visit to
Lyon, offered to grant the Marquisate of Saluzzo to one of Charles Emmanuel's sons as a French fief, but the Duke of Savoy insisted on outright possession and rejected the proposal.
Papal arbitration of the matter proved to be no more successful, and the issue remained unresolved until December 1599, when the king of France received the Duke of Savoy in
Fontainebleau. To resolve the dispute, Henry IV suggested to Charles Emmanuel two alternatives: the return of Saluzzo to France, or to retain the marquisate but to cede in exchange the county of
Bresse, the vicarship of
Barcelonnette, and the
Stura,
Perosa, and
Pinerolo valleys. The Duke of Savoy asked for a period of time to make a decision and returned in early 1600 to
Turin, where he began preparing for an armed conflict against France. He also sent an envoy to
Spain, and was encouraged to hope for Spanish aid from the governor of
Milan,
Pedro Henriquez de Acevedo, Count of Fuentes. Following the expiration of the decision period, Henry delivered an official ultimatum to the Duke of Savoy, to force his cooperation on the issue. Charles Emmanuel, however, continued to refuse to accede to Henry's demands, whereupon the latter decided to resolve the matter by force and declared war against the duchy in August 1600. ==Conflict==
