War of the League of Cambrai


The War of the League of Cambrai, also known by its second stage as the War of the Holy League, was fought from December 1508 to December 1516, as part of the wider Italian Wars of 1494–1559. The main participants of the war, who fought for its entire duration, were France, the Holy Roman Empire, the Papal States, and the Republic of Venice; they were joined at various times by nearly every significant power in Western Europe, including Spain, England, the Duchy of Milan, the Republic of Florence, the Duchy of Ferrara, and the Swiss.
The war was preceded by the Italienzug of Maximilian I, King of the Romans, who crossed into Venetian territory in February 1508 with the imperial army on the way to be crowned Holy Roman Emperor by the pope in Rome. Meanwhile, Pope Julius II, intending to curb Venetian influence in northern Italy, brought together the League of Cambrai, an anti-Venetian alliance consisting of him, Maximilian I, Louis XII of France, and Ferdinand II of Aragon, which was formally concluded in December 1508. Although the League was initially successful, later frictions between Julius and Louis culminated in the pope abandoning the League in 1510 and allying himself with Venice against France.
The Veneto–Papal alliance eventually expanded into the Holy League in 1511, that was also joined by Spain. The League drove the French from Italy in 1512. Later disagreements about the division of the spoils, however, led Venice to abandon the coalition in favor of an alliance with France in 1513. Under the leadership of Francis I, who had succeeded Louis on the throne of France, the French and Venetians would regain the territory they had lost in a campaign culminating in the Battle of Marignano in 1515; the treaties of Noyon and Brussels, which were implemented by January 1517, would essentially return the map of Italy to the status quo of 1508.

Timeline

This is an overview of notable events including battles during the war.
;Prelude
  • July 1506 – March 1507: A popular revolt in Genoa expelled the city's pro-French nobility to Savona. By late November 1506, king Louis XII of France was planning a military expedition to bring Genoa back under pro-French control.
  • 28 March 1507: The Genoese revolutionary council declared war on the king of France, who had already reached Piedmont with his army.
  • 22–29 April 1507: Siege of Genoa. French victory over the Genoese revolutionaries. Louis arranged a triumphal entry and forced the Genoese to swear loyalty to him.
  • April 1507: The Imperial Diet of Konstanz and Maximilian I declared Louis XII of France an enemy of Christianity and a threat to Italy, and requested funding for an Italienzug. Louis XII denied seeking war with the Empire or the Papacy.
  • 14 May 1507: Louis XII left Genoa and held a similar triumphal entry in Milan.
  • 28 June 1507: Louis XII of France and Ferdinand II of Aragon met for six days at Savona to lay the groundwork for the League of Cambrai against Venice, most likely intending to include Maximilian and the Pope into the coalition. Ferdinand departed for Spain on 3 July.
  • July 1507: The Imperial Diet promised Maximilian 12,000 troops for his Italienzug. Because this was not enough to challenge the French in Milan, as he originally intended, Maximilian later ended up deciding to attack Venice instead on the grounds of refusing to ally with him against France, and refusing him passage to Rome.
;Maximilian's Italienzug
  • 24 January 1508: Maximilian requested permission to march to Rome through Venetian territory, but the Venetians suspected the ruse and prepared for war.
  • 4 February 1508: Maximilian I proclaimed himself Holy Roman Emperor in Trento.

  • March–May 1508: Successful Venetian counter-offensives into Imperial territory. The Venetians captured Trieste on 6 May.
  • Summer 1508: Venice agreed to a separate three-year truce with Maximilian without the knowledge or consent of Louis of France. Angered by this 'betrayal', Louis sought to punish the Venetians, and started contemplating a Franco-German alliance with Maximilian against Venice.

    Prelude

In the aftermath of the First Italian War, Pope Alexander VI had, with French assistance, moved to consolidate Papal control over central Italy by seizing the Romagna. The illegitimate son of the Pope, Cesare Borgia, acting as Gonfalonier of the Papal armies, had expelled the Bentivoglio family from Bologna, which they had ruled as a fief, and was well on his way towards establishing a permanent Borgia state in the region when Alexander died on 18 August 1503. Although Cesare managed to seize the remnants of the Papal treasury for his own use, he was unable to secure Rome itself, as French and Spanish armies converged on the city in an attempt to influence the Papal conclave; the election of Pius III stripped Cesare of his titles and relegated him to commanding a company of men-at-arms. Sensing Cesare's weakness, the dispossessed lords of the Romagna offered to submit to the Republic of Venice in exchange for aid in regaining their dominions; the Venetian Senate accepted and had taken possession of Rimini, Faenza, and a number of other cities by the end of 1503.
Julius II, having secured his own control of the Papal armies by arresting and imprisoning Cesare, first in Bologna and later in Ravenna, quickly moved to re-establish Papal control over the Romagna by demanding that Venice return the cities she had seized. The Republic of Venice, although willing to acknowledge Papal sovereignty over these port cities along the Adriatic coast and willing to pay Julius II an annual tribute, refused to surrender the cities themselves. In response, Julius concluded an alliance with France and the Holy Roman Empire against Venice; the death of Isabella I of Castile and the resulting collapse of relations between the parties soon dissolved the alliance, but not before Venice had been induced to abandon several of the cities, except for the three key towns of Rimini, Faenza and Cervia. Julius, although unsatisfied with his gains, did not himself possess sufficient forces to fight the Republic; for the next two years he instead occupied himself with the reconquest of Bologna and Perugia, which, located between Papal and Venetian territory, had in the meantime assumed a status of quasi-independence.
In 1507, Julius returned to the question of the cities in Venetian hands; once again rebuffed by the Senate, he encouraged Emperor Maximilian I to attack the Republic. Maximilian, using his journey to Rome for the Imperial coronation as a pretext, entered Venetian territory with a large army in February 1508 and advanced on Vicenza, but was defeated by a Venetian army under Bartolomeo d'Alviano. A second assault by a Tyrolean force several weeks later was an even greater failure; Alviano not only routed the Imperial army but also seized the entire County of Gorizia, Austrian Istria, as well as Trieste, Fiume, and the westernmost portions of Carniola, forcing Maximilian to conclude a truce with Venice.
