The War of the League of Cambrai brought France and allied powers into direct conflict with Venice over territorial dominance in northern Italy. King Louis XII led French forces into Venetian-held Lombardy, seeking to break Venetian power and reclaim contested lands, setting the stage for a major confrontation.
On 14 May 1509, the French army under Louis XII engaged Venetian rear-guard forces commanded by Bartolomeo d'Alviano near Agnadello. After roughly three hours of fighting, part of the Venetian army abandoned d'Alviano, leading to a decisive French victory with Venetian losses exceeding 4,000 men.
Following the battle, Louis XII occupied the remainder of Lombardy. Venice suffered a catastrophic loss of its mainland territories, with Machiavelli noting the republic had forfeited in a single day the territorial gains of eight centuries, fundamentally weakening Venetian power in the Italian Wars.
