Treaty of Lyon

The Treaty of Lyon, signed in 1601, was an agreement between France and Spain that settled territorial disputes in northern Italy. At the time, both countries sought control over regions like Savoy and Montferrat. The treaty confirmed French sovereignty over the Duchy of Savoy while Spain retained its control over parts of Italy. This agreement helped to stabilize the balance of power in the region, reducing tensions between the two nations and shaping future diplomatic relations in Europe. It marked a significant moment in the ongoing struggle for influence in Italy during the early modern period.
