Italian Wars
The Italian Wars were a series of conflicts fought between 1494 and 1559 in the Italian Peninsula, with subsidiary theatres in Flanders, the Rhineland and Mediterranean Sea. A product of the long-running French–Habsburg rivalry, its primary belligerents were France versus the Holy Roman Empire and Habsburg Spain, supported by numerous Italian states at different stages, along with England, and the Ottoman Empire.
The collapse of the Italic League in 1492 allowed Charles VIII of France to invade Naples in 1494, which drew in Spain and the Holy Roman Empire. Although he was forced to withdraw in 1495, ongoing political divisions among the Italian states made them a battleground in the struggle for European domination between France and the Habsburgs.
After 1503, most of the fighting was initiated by French invasions of Lombardy and Piedmont, but although able to hold territory for periods of time, they could not do so permanently. By 1557, the growth of Protestantism meant the major belligerents faced internal conflict over religion, forcing them to refocus on domestic affairs. This led to the Treaty of Cateau-Cambrésis, under which France was largely expelled from Italy, but in exchange gained Calais from England, and the Three Bishoprics from Lorraine. In turn, Spain acquired sovereignty over the Kingdom of Naples and Kingdom of Sicily in southern Italy, as well the Duchy of Milan in northern Italy.
Fought with considerable brutality, the wars took place against the background of religious turmoil caused by the Reformation, particularly in France and the Holy Roman Empire. They are seen as a turning point in the evolution from medieval to modern warfare, with the use of the arquebus or handgun becoming common, along with significant technological improvements in siege artillery. Literate commanders and modern printing methods also make them one of the first conflicts with a significant number of contemporary accounts, including those of Francesco Guicciardini, Niccolò Machiavelli, and Blaise de Montluc.
Background
Largely driven by the rivalry between the Republic of Venice and the Duchy of Milan, the long-running Wars in Lombardy had finally been ended by the 1454 Treaty of Lodi. Followed shortly thereafter by a non-aggression pact known as the Italic League, it led to a forty-year period of stability and economic expansion, marred only by the 1479 to 1481 Pazzi conspiracy and 1482 to 1484 War of Ferrara. The League's main supporter was the Florentine ruler Lorenzo de' Medici, who also pursued a policy of excluding France and the Holy Roman Empire from the Italian peninsula.Lorenzo's death in April 1492 severely weakened the League at a time when France was seeking to expand in Italy. This originated when Louis XI of France inherited the County of Provence from his cousin Charles IV of Anjou in 1481, along with the Angevin claim to the Kingdom of Naples. His son Charles VIII succeeded him in 1483 and formally incorporated Provence into France in 1486; its ports of Marseille and Toulon provided direct access to the Mediterranean and thus the ability to pursue his territorial ambitions.
In the run-up to the First Italian War, Charles sought to secure the neutrality of other European rulers through a series of treaties. These included the November 1492 Peace of Étaples with Henry VII of England and the March 1493 Treaty of Barcelona with Maximilian I, Holy Roman Emperor.
History
Italian War of 1494–1495
The war began when Ludovico Sforza, then Regent of Milan, encouraged Charles VIII of France to invade Italy, using the Angevin claim to the throne of Naples as a pretext. This in turn was driven by the intense rivalry between Ludovico's wife, Beatrice d'Este, and that of his nephew Gian Galeazzo Sforza, husband of 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.In October, Ludovico formally became Duke of Milan following the death of Gian Galeazzo, who was popularly supposed to have been poisoned by his uncle, and the French marched through Italy virtually unopposed, entering Pisa on 8 November, Florence on 17th, and Rome on 31 December. Charles was backed by Girolamo Savonarola, who used the opportunity to establish a short-lived theocracy in Florence, while Pope Alexander VI allowed his army free passage through the Papal States.
In February 1495, the French reached Monte San Giovanni Campano in the Kingdom of Naples and despatched envoys to negotiate terms with its Neapolitan garrison, who murdered them and sent their mutilated bodies back to the French lines. On 9 February, the enraged besiegers breached the walls of the castle with artillery fire, then stormed it, killing everyone inside. Known as the "Sack of Naples", widespread outrage within Italy allied with concern over the power of France led to the formation of the League of Venice on 31 March 1495, an anti-French alliance composed of Republic of Venice, Milan, Habsburg Spain, and the Holy Roman Empire.
Later joined by Florence, following the overthrow of Savonarola, the Papal States and Mantua, this coalition cut off Charles and his army from their bases in France. Charles' cousin, Louis d'Orleans, now tried to take advantage of Ludovico's change of sides to conquer Milan, which he claimed through his grandmother, Valentina Visconti. On 11 June, he captured Novara when the garrison defected, and reached Vigevano, forty kilometres from Milan. At this crucial point, Ludovico was incapacitated either by a stroke or nervous breakdown, while his unpaid soldiers were on the verge of mutiny. In his absence, his wife Beatrice d'Este took personal control of the Duchy and the siege of Novara, with Louis eventually forced to surrender in return for his freedom.
Having replaced Ferdinand II of Naples with a pro-French government, Charles turned north and on 6 July was intercepted by the League outside Fornovo di Taro. In the resulting Battle of Fornovo, the French forced their opponents back across the Taro river and continued onto Asti, leaving most of their supplies behind. Both sides claimed victory but the general consensus favoured the French, since the League suffered heavier casualties and failed to halt their retreat, the reason for fighting in the first place. In the south, despite some initial reverses, by September 1495 Ferdinand II had regained control of his kingdom. Although the French invasion achieved little, it showed the Italian states were rich and comparatively weak, making future intervention attractive to outside powers. Charles himself died on 7 April 1498, and was succeeded by the former Duke of Orleans, who became Louis XII.
Italian Wars of 1499–1504
The next phase of the conflict originated in the long-standing rivalry between Florence and the Republic of Pisa, which had been annexed by Florence in 1406 but took advantage of the French invasion to regain its independence in 1494. Despite Charles' retreat in 1495, Pisa continued to receive support from Genoa, Venice and Milan, all of whom were suspicious of Florentine power. In order to strengthen his own position, Ludovico once again invited an external power to settle an internal Italian affair, in this case Emperor Maximilian I. In doing so, Maximilian hoped to bolster the League of Venice, which he viewed as an essential barrier to French intervention, but Florence was convinced he favoured Pisa and refused to accept mediation. To enforce a settlement, in July 1496 Maximilian besieged the Florentine city of Livorno, but withdrew in September due to shortages of men and supplies.Following the death of Charles VIII in April 1498, Louis XII began planning another attempt on Milan, while also pursuing his predecessor's claim to the Kingdom of Naples. Aware of the hostility caused by French ambitions in Italy, in July 1498 he renewed the 1492 Peace of Étaples with England and signed a treaty confirming French borders with Burgundy. This was followed in August by the Treaty of Marcoussis with Ferdinand II of Aragon; although it did not address outstanding territorial disputes between the two countries, it agreed "have all enemies in common except the Pope." On 9 February 1499, Louis signed the Treaty of Blois, a military alliance with Venice against Ludovico.
With these agreements finalised, a French army of 27,000 under the Milanese exile Gian Giacomo Trivulzio invaded Lombardy, and in August besieged Rocca d'Arazzo, a fortified town in the western part of the Duchy of Milan. The French siege artillery breached the walls in less than five hours and after the town capitulated, Louis ordered the execution of its garrison and senior members of the civil administration. Other Milanese strongholds surrendered rather than face the same fate, while Ludovico, whose wife Beatrice had died in 1497, fled the duchy with his children and took refuge with Maximilian. On 6 October 1499, Louis made a triumphant entry into Milan.
Florence now asked for French assistance in retaking Pisa, a request Louis was in no hurry to fulfil since they had refused to support his capture of Milan. He was also initially occupied in defeating efforts to regain his duchy by Ludovico, who was captured at Novaro in April 1500 and spent the rest of his life in a French prison. However, Louis needed to maintain good relations with Florence, whose territory he would have to cross in order to conquer Naples, and on 29 June 1500 a combined Franco-Florentine army appeared outside Pisa. Once again, the French artillery quickly opened a gap in the walls but several assaults were repulsed and the siege was abandoned on 11 July.
With Milan firmly in his control, Louis returned to France and left the Florentines to blockade Pisa, which eventually surrendered in 1509. Anxious to begin the conquest of Naples, on 11 November he signed the Treaty of Granada with Ferdinand II of Aragon, an agreement to divide the kingdom between the two. Since Ferdinand had supported the expulsion of the French from Naples in 1495, Louis hoped these concessions would allow him to acquire the bulk of the kingdom without an expensive war. His action was criticised by contemporaries like Niccolò Machiavelli and modern historians, who argue the 1499 Treaty of Marcoussis already gave Louis everything he needed, while inviting Spain into Naples could only work to his detriment.
In July 1501, the French army reached Capua; strongly defended by forces loyal to Frederick of Naples, it surrendered on 24 July after a short siege but was then sacked. In addition to the extensive material destruction, many women were subjected to mass rape and estimates of the dead ranged from 2,000 to 4,000, actions that caused consternation throughout Italy. Resistance crumbled as other towns tried to avoid the same fate and on 12 October Louis appointed the Duke of Nemours his viceroy in Naples. However, the Treaty of Granada had left the ownership of key Neapolitan territories undecided and disputes over these quickly poisoned relationships between the two powers. This led to war in late 1502, which ended with the French being expelled from Naples once again after defeats at Cerignola on 28 April 1503, and Garigliano on 29 December.
