Sforza’s purpose was, however, only half accomplished. Though the lady was won, the Dukedom remained to be secured. But he had to reckon with his father-in-law’s antipathy, doubtless originating in a deep-seated pride of race, and also with the hostile party—led by Niccolò Piccinino and his sons—which was all-powerful in Milan and virtually ruled the now decrepit Filippo. The Milanese armies before long moved once more against Sforza, who retaliated by accepting the command of the Venetian forces and carrying fire and sword right up to the walls of Milan. The terrified Filippo was compelled to seek reconciliation with his offended son-in-law, and to the chagrin of Venice, Sforza abandoned her side in the hour of success and rapidly won back for the Visconte the Milanese territories which he had just conquered for the Republic. At this juncture the Duke, plagued by the irreconcilable importunities of the two parties, used the only resource left to him wherewith to baffle them both. Without confirming his promises to Sforza he fell sick, and, obstinately refusing all remedies, let himself die (1447), reiterating with his last breath a wish that after his death everything might fall to ruin.

And so it did. The city was immediately plunged into confusion and uproar. Pretenders sprang up on every side, and the old faction trouble threatened to overwhelm all order. The cities subject to Milan rebelled, and once more the great State of the Visconti broke up into independent fragments. Meanwhile, in the midst of the tumult in the capital itself, the beautiful word Liberty, still remembered from the glorious days of Milan’s Republican freedom, was breathed by a few noble and disinterested citizens. It was acclaimed by the people, who thought it meant relief from taxation, and was accepted by the various factions, each hoping to make profit out of it. Amid enormous enthusiasm the Golden Republic of St. Ambrogio was constituted, and the supreme authority delegated to a few leading men, who were called Captains and Defenders of the Liberty of Milan.

The first act of the Republic was to sweep away the Castle of Porta Giovia, stronghold and symbol of hated tyranny. The people exulted to see it fall, but many thoughtful men, remembering the predatories who coveted the rich city, were dismayed. Nor did the new Constitution prosper. The Milanese had lost all capacity for self-government under the long-continued despotism of the Visconti. ‘Nothing could make Milan free,’ pronounced Macchiavelli later, ‘being altogether corrupt, as was seen after the death of Filippo Visconte, when desiring to establish liberty she neither was able, nor knew how, to maintain it.’ The tyranny of hostile factions triumphed over the best intentions of the Republicans, and the thoughtless people arrayed themselves one against another, behind leaders whose only aim was to subjugate them. Those who had really pure motives were drawn hopelessly into the whirlpool, and the Defenders of Liberty oppressed each other, and the citizens generally, with every cruelty and injustice.

Meanwhile the Duchy was claimed by the Guelf party for Alfonso of Aragon, on the strength of a will which his supporters had extracted from the dying Filippo. A pretension—first threat of the misfortune that was to fall later on Milan—was also advanced by the Duke of Orleans, son of Filippo’s sister, Valentina Visconte. The Emperor claimed the Duchy as a vacant fief. More dangerous than any of these pretenders was Venice, greedy to extend her empire. But strongest of all was the resolution of Francesco Sforza, who mended the flaw of illegitimacy in his wife’s claim by the strength of his good sword. General of the Milanese armies at Filippo’s death, he used his power to defend the State from the attacks of Venice, and to subdue it gradually to his own sway. But his enemies were strong. The Piccinini, Francesco and Jacopo, warred against him with arms and intrigue, in alliance with the old Guelf faction. They held Milan against him, but their councils were confused by passion and divisions, and the great general drew steadily nearer to the city. He defeated the Piccinini in the field, and outwitted their perfidious diplomacy with an equal craft. He leagued with Venice and Florence against the new Republic, defeated the Duke of Savoy, whom Filippo’s widow, Maria of Savoy, had enlisted against him, and cutting Milan off from all friends or help, laid siege to the capital itself.

Yet still the citizens clung to their illusion of liberty, and obstinately refused to submit to a new master. Amid fierce tumult they appointed fresh magistrates from the lowest ranks, persecuted and proscribed the nobles, and put an enormous price on the head of the ‘perfidious’ Francesco Sforza, decreeing death to any who breathed his name without a curse. But their resolution was useless. For some time they kept the invader at bay with great spirit, aided by his party foes; but the death of Francesco Piccinino at this juncture was a serious blow to the defence. All trade was stopped by the siege, and general ruin threatened this community, long used to wealth and ease. The city was now reduced to grievous straits by famine. The desperate struggles of the democratic leaders, Gio. Ossona and Gio. da Appiano, to maintain their rule by blood and torture in the face of the growing discontent and the ceaseless intrigues of Sforza’s partisans, made them odious to all. Tumults broke out, and everywhere, says Corio, were heard lamentations, weeping and cries. The Captains of Liberty were no longer feared or obeyed. When in desperation they began to parley with Venice, the citizens unanimously agreed that submission to Sforza was a lesser evil than falling into the jaws of San Marco, and a rising of Ghibellines and friends of the Condottiere succeeded in sweeping away the Republic of St. Ambrogio, and opening the gates at last to the victorious Francesco, and to a new era of peace, prosperity and servitude (1450).

Amid the wild applause of countless thousands, the great warrior rode in, followed by his soldiers, whose necks and shoulders were hung round with loaves of bread. It was a fine thing to see—in Corio’s words—with what eagerness the people snatched off the bread, and with what voracity they devoured it. So enormous was the throng, all shouting Sforza and Duca, that the conqueror and his horse were literally lifted up and carried on men’s shoulders. But even yet one or two, among them the high-hearted Ambrogio Trivulzio, opposed his entrance, demanding of him guarantees for the liberty of the city. They were overpowered, however, by the multitudes, and Francesco Sforza was proclaimed Duke by general consent of the citizens.

Milan had immediate consolation for her lost liberty. By the wise provision of the conqueror, such generous abundance flowed in after the herald loaves of the soldiers, that in three days it seemed as if there had been no siege at all. Order was restored with a firm and kindly hand, and the splendid feasts and tournaments, continuing for nine days, and drowning the memory of past afflictions, hid no cruel deeds of vengeance upon the Duke’s political opponents.

Italian historians generally agree in a favourable estimate of Francesco Sforza. Corio, the historian, whose father was a gentleman in the service of the Sforza, and he himself from his youth up, attached to the ducal household, describes the first Duke as liberalissimo, full of kindness, a lover of justice and religion, and declares that none observed faith better than he. This last, in fifteenth century Italy, was not saying much. More impartial writers, while praising his courage, ability and general humanity, recognise that his triumph was due as much to perfidy and political suppleness as to valour. He was a man of his time, and his moral standard was that expressed by Macchiavelli later, who, writing of the Sforza, excuses him on the ground that great men are ashamed to lose, not to gain, by deception.

As Duke of Milan, Francesco still resorted to the same practices. The long tyranny of the Visconti, the strange cruelties and mysterious misanthropic habits of the later princes, the intercourse of the last Duke with astrologers and necromancers, which had wrapped him in a sort of diabolical atmosphere, made the idea of a despot repulsive and awful to the people, apart from their fear of oppression. But the brave, robust presence, the frank and genial manner of this lord of the battlefield and camp, who nothing esteemed astrologers, did much to overcome their prejudices, and his rejection of the gorgeous symbols of sovereignty prepared for his entry as superstitioni dei Re, and unfit for a simple soldier, was carefully calculated to win their confidence. But he dared not trust them. No sooner was he seated on the throne than with false assurances that his only motive was the safety and embellishment of the city, he began to rebuild the castle of Porta Giovia, and to fortify it with enormous walls, and with two huge round towers commanding the habitations of his subjects themselves, an ever visible warning against rebellion. The Milanese, however, made no attempt to shake off the yoke. The bulk of the people resumed with joy their industrial occupations, too content with relief from immediate afflictions to question of the future. They might well, too, recognise that submission to the successful soldier was Milan’s only hope of salvation as an independent State.

In Italy, as a whole, the elevation of Francesco Sforza meant the boon of peace. It enrolled on the side of order and stability the chief element of disturbance in the country. For more than a century continual strife had been kept up by the Condottieri in their own interests. But now that the greatest of them all had attained a solid throne, the era of their irresponsible energies was over. The splendid title and wealth of the Visconti, and the immense resources of the Lombard capital, united with the military skill and renown of the Sforza, could consolidate and safeguard once again that great empire of the Snake, whose decrepitude had been the chief opportunity of the Condottieri, and the provocation of the late wars. On the part chosen by Milan depended largely the fate of the whole peninsula. The far-eyed ambition of the Visconti had chosen war. The new dynasty, on the contrary, preferred to develop the vast wealth of the State which it had won rather than increase its bounds, and was content to relinquish for the sake of peace all pretensions to the cities once belonging to the Visconti, and now usurped by Venice. Neither Francesco nor his successor sought the aggrandisement of their dominions. And where the Visconti, aggressive though they were, had studied the peace of Italy in the larger sense, they were nobly followed by the two first Sforza. Gian Galeazzo’s national policy—Italy for the Italians—his care to keep those Alpine gates, whose keys had been committed to Milan’s charge, locked against a possible invader, was adopted and carried on by the Sforza, through nearly half a century; and when it was reversed, and the flood of disaster and ruin let loose upon the country by Francesco’s younger son, the brilliant prince to whom Fate had denied no gift except just those two qualities which had made the Visconti great—judgment and knowledge of men—there is reason to believe that fear rather than ambition was the motive.
