The Second Italian War (1499–1504), sometimes known as Louis XII's Italian War or the War over Naples, was the second of the Italian Wars; it was fought primarily by Louis XII of France and Ferdinand II of Aragon, with the participation of several Italian powers. In the aftermath of the First Italian War, Louis was determined to press his claim on the thrones of Milan and Naples. In 1499 Louis XII invaded Lombardy and seized Milan, to which he had a claim in right of his paternal grandmother Valentina Visconti, Duchess of Orléans.
In response to threats from the Republic of Venice and the Kingdom of Naples, Ludovico Sforza the duke of Milan had invited France into Italy to protect Milan from her enemies. In answer to this request for aid, King Charles VIII of France came to Sforza's assistance by invading Italy in the first Italian Wars (1494-1498). However, in the first battle of that first Italian war—the battle of Fornovo on 6 July 1495—Ludovico Sforza suddenly and unexpectedly changed sides—thus, joining the Venetians and the Kingdom of Naples against the French.
Charles VIII died on 7 April 1498 and was followed to the throne by Louis XII of France. Immediately, King Louis concluded an alliance with the Republic of Venice and obtained some Swiss mercenaries and invaded the Duchy of Milan under the condition that the Lombardian territories be split between Venice and France. Papal support was given for the campaign in exchange for Louis XII's military support for Cesare Borgia's Romagna campaigns. Ludovico Sforza, having also hired an army of Swiss mercenaries returned to Milan find it occupied by Gian Giacomo Trivulzio, who had joined the French; Ludovico's army was soon scattered, and he himself imprisoned in France. Following the final overthrow of Sforza, the Duchy of Milan would serve, for the next twelve years, as a French stronghold and as a springboard for further French military adventures in Italy.
As the summer campaign season of the year 1500 neared, Louis XII became worried about the intentions of newly unified Spain to his west if he moved into Italy to the east. The Spanish monarchs Ferdinand and Isabella were known to be fearful of a new rapprochement between Louis XII and the Italian powers. They might invade France from the west, while Louis XII had his armies in Italy, thus, involving Louis in a war on two fronts. To avoid this prospect, Louis signed an agreement with Spain that divided the spoils of Naples between France and Spain when Naples was conquered. This was the Treaty of Grenada signed on 11 November 1500.
The Treaty of Grenada is a watershed document. It was an invitation to Spain to enter into the political affairs of Italy. The Treaty has been criticized by modern historians as well as contemporaries of Louis XII. Most notably, Niccolò Machiavelli, criticized Louis XII for proposing and signing the Treaty of Grenada in his masterpiece the Prince. Spanish influence would grow and later haunt Louis and his successors to the throne of France.
In his claim to Milan, King Louis XII asserted a family inheritance to support his claim to the Duchy of Milan. However, in the case of Naples, Louis had no inheritance to claim. Instead, Louis XII's claim to Naples rested entirely on Charles VIII's claim and his temporary occupation of the Naples. This was called the "Angevin inheritance." The Angevin inheritance came to Charles VIII as early as 1481 and was the basis of Charles' military campaign against Naples in 1495. Louis XII claimed the Angevin inheritance only because he, Louis XII, was the successor of Charles VIII to the throne of France. The present king of Naples, Frederick IV claimed the throne of Naples upon the death in 1496 of his nephew, Ferdinand II. Ferdinand II was the son of Alfonso II of Naples. Alfonso II had abdicated the throne of Naples to Charles VIII in 1495. Thus, both Ferdinand and his uncle, Frederick IV were considered an illegitimate inheritors and usurpers of the Neapolitan title that rightly belonged to the king of France—now Louis XII.
Louis XII and the monarchs of Spain had agreed to these terms on 11 November 1500 in the Treaty of Grenada and Pope Alexander VI, nominal overlord of the Kingdom of Naples, provided his approval of this deal on 25 June 1501.
Pursuant to the Treaty of Grenada, French and Aragonese armies seized Naples on 2 August 1501. Although it was agreed that Louis XII should assume the throne of Naples, Louis and the monarchs of Spain soon quarreled over the division of the rest of the spoils. Soon war broke out between again between France and Spain. Spain expelled the French from Naples in
When the conflict broke out again in the second half of 1502, Don Gonzalo de Cordoba lacked numeric superiority, but was able to apply the lessons learned in 1495 against the Helvetic infantry; moreover, the Spanish terceros, accustomed to close combat after the Reconquista, addressed some of this imbalance. Cordoba avoided encounter with the enemy at first, hoping to lure the French into complacency. Later, the conflict became characterized by short skirmishes. During this campaign, a French knight, il La Motte, was captured by Spanish forces and later used this time as a hostage to declare his famous Challenge of Barletta on 13 February 1503. Chronic in-fighting between the Italian and French knights, as well as a better supply-line guaranteed by the Spanish navy, gave Cordoba the upper hand against the French, who suffered defeat at Cerignola on 28 April 1503 and Garigliano on 29 December 1503. Louis XII was forced to abandon Naples and on 2 January 1504 left Naples to withdraw to Lombardy.
The Treaty of Granada was a secret pact, agreed to on 11 November 1500, by Louis XII of France and Ferdinand II of Aragon, in which the two parties agreed to divide the Mezzogiorno between themselves after removing Frederick IV of Naples from the Neapolitan throne. Their plans were realized on 25 June 1501 when they were both invested by Pope Alexander VI. On the 25 July 1501, Frederick IV of Naples, hoping to avoid another military conflict between the two national monarchies on Italian soil, abdicated Naples and Campania in favour of the French King. It is worth noting that, as Francesco Guicciardini points out in the Discorso di Logrogno, the partition of the Mezzogiorno between the houses of Aragon and Orléans neglected to take into account the economic system of a region dominated by sheep-rearing and its concomittant transhumance 
The Treaty of Lyon was signed on 31 January 1504 between Louis XII of France and Ferdinand II of Aragon. Based on the terms of the treaty, France ceded Naples to Spain. Moreover, France and Spain defined their respective control of Italian territories. France controlled northern Italy from Milan and Spain controlled Sicily and southern Italy.
The Treaty of Blois of 22 September 1504 concerned the proposed marriage between Charles of the House of Habsburg, the future Charles V, and Claude of France, daughter of Louis XII and Anne of Brittany.
If the King Louis XII were to die without producing a male heir, Charles of the House of Habsburg would receive as dowry the Duchy of Milan, Genoa and its dependencies, the Duchy of Brittany, the counties of Asti and Blois, the Duchy of Burgundy, the Viceroyalty of Auxonne, Auxerrois, Mâconnais and Bar-sur-Seine.
- Her marriage contract with the Duke of Orleans stipulated that in failure of male heirs, she would inherit the Visconti dominions.
