Second loss of Milan by France

The Second loss of Milan by France was the decisive reversal of Louis XII’s Italian expansion and the clearest demonstration that conquest cannot be maintained by battlefield success alone. France had recovered Lombardy and appeared dominant, yet Louis repeatedly converted potential allies into enemies and strengthened powers that could later oppose him. The eventual expulsion of the French from Italy was therefore presented not as an inexplicable accident, but as the consequence of identifiable political and strategic failures.

Causes and Background

The immediate background was Louis XII’s recovery of Milan. After the earlier loss, a mere alarm raised by Ludovico Sforza had been enough to recover the city; on the second occasion, however, the entire political order had to be mobilized against France, and French armies were destroyed and driven out of Italy. The contrast marks the event’s central reversal: a conquest once vulnerable to a single local challenge became vulnerable only after a broad opposition had formed, but that opposition ultimately proved overwhelming.

Louis had entered Italy through Venetian ambition. Venice hoped to receive half of Lombardy, while Louis sought a foothold in a country where France had no friends and where the conduct of Charles VIII had closed every door. The arrangement initially seemed successful. Once Lombardy was recovered, Genoa submitted, Florence came to terms, and the Marquis of Mantua, the Duke of Ferrara, the Bentivogli, the Countess of Forli, the Lords of Faenza, Pesaro, Rimini, Camerino, and Piombino, together with the citizens of Lucca, Pisa, and Siena, offered friendship. Venice had gained only a couple of towns in Lombardy while making the French King master of two-thirds of Italy, and had reason to regret its bargain.

The opportunity was lost when Louis helped Pope Alexander VI occupy Romagna. By strengthening the Church with extensive temporal power, he weakened himself: friends and weaker powers that had attached themselves to France were alienated, while the papacy acquired a greater material base. Louis then had to enter Italy personally to restrain the Pope’s ambition and prevent him from becoming master of Tuscany. The act that was meant to secure influence thus created a stronger rival and compelled further intervention.

A second major error followed from Louis’s desire for the Kingdom of Naples. Instead of leaving a king willing to hold Naples as a tributary, he divided the kingdom with Ferdinand II of Aragon, bringing a powerful foreign rival into Italy. The new arrangement gave the ambitious and discontented in Naples someone to whom they could turn, and the ruler installed in place of the former king was strong enough to expel France. The narrative distinguishes the partition of Lombardy with Venice, which could be defended as the price of gaining a foothold in Italy, from the partition of Naples, which was not supported by comparable necessity.

The Course of the Loss

The loss resulted from a chain of six mistakes. Louis destroyed weaker States, strengthened a Prince who was already powerful, introduced a very powerful stranger into Italy, failed to reside in the conquered country, and failed to establish colonies there. He then added a sixth error by depriving Venice of its dominions. Venice, while powerful, had helped prevent other States from attacking Lombardy; after its ruin, France removed a barrier that had indirectly protected French control.

Louis’s concessions were defended as attempts to avoid war, but the event exposes the danger of postponing rather than preventing conflict. By granting Romagna to Pope Alexander VI and Naples to Spain, France did not remove the causes of war. It allowed rival powers to consolidate their positions until a later struggle would take place under less favorable conditions. The same reasoning applied to Louis’s commitments to the Pope, including the promised undertaking in exchange for the dissolution of his marriage and the cardinal’s hat conferred on Georges d’Amboise: political obligations could not erase the strategic consequences of empowering a rival.

The French failure was also institutional. A newly acquired State joined to an older dominion is easier to retain when it shares language and customs with the conqueror, provided the old laws and taxes are left intact and the former ruling line is removed. Where language, usages, and laws differ, the Prince must rely on exceptional fortune and address, reside in person, or establish colonies that secure the Province at lower cost than a permanent army. Louis did none of these things consistently. His authority remained an external conquest rather than becoming an established political order.

Consequences and Aftermath

The immediate consequence was the destruction and expulsion of French armies from Italy and the second loss of Milan. France had not merely surrendered a city; it had lost the position created by its earlier recovery of Lombardy. The reversal followed the transfer of power to the Church and Spain, the alienation of former friends, and the removal of Venice as a counterweight. The event therefore changed the balance of Italy as much as it changed French possession of Milan.

The episode is connected to a broader principle: a ruler who causes another power’s greatness is himself undone. France had enlarged the Church, introduced Spain into Italy, and then suffered ruin through the powers it had helped raise. The failure was not attributed to Louis’s ambition alone. Acquiring is described as natural, and attempts within one’s power may deserve praise; blame follows when a ruler persists in undertakings beyond his strength or accepts arrangements that create stronger enemies than the territory gained can support.

The event also clarifies why the structure of the conquered State matters. Alexander the Great’s conquest of Asia remained secure after his death because the kingdom of Darius III was organized under a single Prince and his servants; once Darius died, no independent barons remained to generate resistance, and the only disorders came from the ambitions and jealousies of Alexander’s successors. France faced a different environment. Italy contained numerous powers, rival rulers, old memories, and political actors capable of opening or closing access to territory. The same conqueror could therefore succeed in one kind of State and fail in another.

Military and Political Significance

The Second loss of Milan by France belongs to the book’s larger distinction between possessing power and controlling it. A Prince who enters a new Province must have the good will of its inhabitants, must anticipate disorders before they mature, and must avoid creating enemies among those who helped him. Military force can seize a city, but it cannot by itself turn a mixed Princedom into a durable possession. Louis’s first recovery of Milan had benefited from favorable local conditions; the second loss showed that those conditions had been squandered.

The contrast with Cesare Borgia reinforces the military lesson. Cesare Borgia first entered Romagna with French auxiliaries and took Imola and Forli. Finding foreign troops unreliable, he employed mercenaries from the Orsini and Vitelli, then dismissed them when they proved fickle, false, and treacherous, finally relying on forces of his own raising. His reputation increased as he became visibly master of his own arms. Louis’s Italian policy moved in the opposite direction: rather than consolidating independent capacity and local security, it repeatedly relied on arrangements that empowered others.

The comparison extends beyond Italy. The Romans secured Capua, Carthage, and Numantia by destroying them, while their attempt to hold Greece through its own laws and freedom failed until many cities were destroyed. Republics retained a fierce memory of liberty and a thirst for revenge; cities that had lived under princes were easier to attach to a new ruler once their ruling line had disappeared. Milan’s repeated transfer demonstrates the same structural point in a different form: a conquest remains exposed when its political loyalties, institutions, and neighboring powers have not been brought into a stable relationship with the conqueror.

Historical and Narrative Significance

The event functions as a case study in political causation rather than as a simple military defeat. Its meaning is assembled retrospectively from the decisions that preceded it: the Church was enlarged, Spain was introduced, Venice was ruined, residence was neglected, colonies were not sent, and weaker States were destroyed without producing lasting security. Each choice narrowed France’s future options and increased the strength of its eventual opponents.

Its most forceful irony lies in the reversal of apparent success. Louis recovered Lombardy, received submissions from across Italy, and seemed to possess the authority that Charles VIII had lost. Yet the very expansion that made France powerful also made its position fragile. The event confirms that the durability of a conquest depends less on the brilliance of acquisition than on whether the conqueror understands the political relationships that acquisition creates. Milan was lost again because France won territory while losing the conditions that could have enabled it to keep that territory.
