Background The
Italian War of 1494–1498 began when
Ludovico Sforza, then
Regent of Milan, invited
Charles VIII of France to invade Italy, using the
Angevin claim to the
Kingdom of Naples as a pretext. This in turn was driven by the intense rivalry between Ludovico's wife,
Beatrice d'Este, and the wife of his nephew
Gian Galeazzo Sforza,
Isabella of Aragon. Despite being the hereditary Duke of Milan, Gian Galeazzo had been sidelined by his uncle in 1481 and exiled to
Pavia. Both women wanted to ensure their children inherited the Duchy and when Isabella's father became
Alfonso II of Naples in January 1494, she asked for his help in securing their rights. In September Charles invaded the peninsula, which he justified by claiming he wanted to use Naples as a base for a crusade against the
Ottoman Turks. Although Charles conquered Naples with relative ease, after his return to France,
Ferdinand II of Naples quickly regained his kingdom. He did so with support from his distant Trastamaran relative
Ferdinand II of Aragon, who as ruler of the neighbouring
Kingdom of Sicily viewed French expansion in
southern Italy as a threat. In September 1496, Ferdinand of Naples was succeeded by his uncle
Frederick.
War for Milan Charles VIII died on 7 April 1498 and was succeeded by his second cousin
Louis XII of France, who inherited the Angevin claim to Naples while also claiming the
Duchy of Milan through his grandmother
Valentina Visconti. His lawyers also asserted that Milan naturally belonged to the French since it had been founded by their ancestors the
Gauls, as stated by Roman historian
Livy. Louis now approached the
Republic of Venice, then the leading military power in
Northern Italy. Venice had been financing
Pisa in its fight for independence from
Florence, which was supported by Milan. Doing so had proved extremely expensive while Venice was also concerned by the
Ottoman threat to their maritime possessions. As a result, the
Great Council was open to an alliance with France to remove Ludovico, although some members disagreed, including
Agostino Barbarigo, the current
Doge of Venice. In their initial talks, the Venetians demanded lands on both sides of the
Adda river, which Louis considered excessive, while Venice rejected a French request for a subsidy of 100,000
ducats. Under a deal brokered by
Ercole I d'Este, Duke of Ferrara, Venice was granted
Cremona along with lands on the eastern bank of the Adda, and agreed to pay part of Louis' expenses. They would also supply 1,500
cavalry and 4,000 infantry for an attack on Milan from the east and allow Louis to capture
Genoa. In return, France promised to provide military support if the
Ottomans attacked Venice while they were at war with Milan. The
Treaty of Blois was signed on 9 February 1499, while
Pope Alexander VI approved the invasion of Milan in exchange for the French backing
Cesare Borgia's campaign in
Romagna. Louis hired a strong force of
Swiss mercenaries and led by
Gian Giacomo Trivulzio, his troops quickly over-ran the duchy. Ludovico and his children took refuge in Germany with Emperor
Maximilian, while the French entered Milan on 6 October 1499. Following his victory, Louis' Franco-Visconti heraldry and name were painted over the Sforza arms at the
Castello Sforzesco, while portraits of French kings replaced those of the Sforza family in the library at
Pavia. However, tensions soon emerged within the Franco-Venetian alliance over Pisa; while the Venetians preferred an independent Pisa as a way to weaken Florence, Louis needed Florentine support for his attack on Naples. With help from Emperor Maximilian, Ludovico recruited an army of 20,000 mercenaries and retook Milan on 5 February 1500; his army then moved north and captured
Novara from the French on 21 March. However, his inability to pay his troops meant this success proved short-lived and on April 10 Ludovico's army was annihilated at the
Battle of Novara. Despite disguising himself as a Swiss pikeman to evade imprisonment by the French, Sforza was betrayed by his own men and turned over to the French on April 15 and sent into captivity at
Lys-Saint-Georges, remaining in French dungeons until his death in 1508. For the next thirteen years, French possession of Milan gave them a base form which to intervene directly in Italy. Despite defeating Ludovico, Louis XII viewed his brief but violent restoration as inspired by
Pope Alexander VI and led him to deeply distrust the Holy See end up with France openly hostile and attempting to depose the next pope,
Julius II.
Franco-Spanish efforts As the summer campaign season of the year 1500 neared, Louis XII became worried about the intentions of newly unified Spain as he moved further into Italy, drawing his forces eastward. 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, and thus involve Louis in a war on two fronts. In the
Treaty of Granada, signed by Louis and Ferdinand on 11 November 1500, the two agreed Louis would become King of Naples and gain control of
Naples,
Terra di Lavoro, and
Abruzzi while Ferdinand was made Duke of
Calabria and
Apulia; the territories between were to be shared along with their revenue. On 25 June 1500, these terms were approved by
Pope Alexander VI, nominal overlord of the Kingdom of Naples. On 25 July 1501,
Frederick IV of Naples abdicated in favour of Louis and died in French captivity in 1504;
Francesco Guicciardini points out in the
Discorso di Logrogno (1512) that 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 concomitant
transhumance. Within two years, differences over the allocation of the disputed areas led to war between the two powers. == Third Italian War ==
