Treaty of Lodi

The Treaty of Lodi, concluded in 1454, ended hostilities among the leading states of northern Italy, chiefly the Republic of Venice, the Duchy of Milan, and the Republic of Florence. The agreement followed decades of warfare over the dominance of Lombardy, including the wars surrounding the rise of Francesco Sforza to the duchy of Milan, which had drawn the major Italian powers into shifting alliances and conflict.

The peace recognized Sforza's possession of Milan and established agreed borders among the contracting states, notably fixing the boundary between Milan and Venice. The settlement reflected a desire among the exhausted powers for stability, heightened by the alarming fall of Constantinople to the Ottoman Turks in 1453, which underscored the need for unity among Christian states.

Out of the Treaty of Lodi grew the Italic League, a broader alliance that included the papacy and the Kingdom of Naples, designed to preserve a balance of power on the peninsula. The arrangement ushered in roughly four decades of relative peace in Italy, lasting until the French invasion of 1494 shattered the equilibrium and opened the era of the Italian Wars.
