the most important causes of the final ruin of Italian independence.

Of the Duchy of Milan it is not necessary to speak at any great length,
although the wars between France and Spain were chiefly carried on for
its possession. It had been formed into a compact domain, of
comparatively small extent, but of vast commercial and agricultural
resources, by the two dynasties of Visconti and Sforza. In 1494 Lodovico
Sforza, surnamed Il Moro, ruled Milan for his nephew, the titular Duke,
whom he kept in gilded captivity, and whom he eventually murdered. In
order to secure his usurped authority, this would-be Machiavelli thought
it prudent to invite Charles VIII. into Italy. Charles was to assert his
right to the throne of Naples. Lodovico was to be established in the
Duchy of Milan. All his subsequent troubles arose from this transaction.
Charles came, conquered, and returned to France, disturbing the
political equilibrium of the Italian States, and founding a disastrous
precedent for future foreign interference. His successor in the French
kingdom, Louis XII., believed he had a title to the Duchy of Milan
through his grandmother Valentina, daughter of Gian Galeazzo Visconti.
The claim was not a legal one; for in the investiture of the Duchy
females were excluded. It sufficed, however, to inflame the cupidity of
Louis; and while he was still but Duke of Orleans, with no sure prospect
of inheriting the crown of France, he seems to have indulged the fancy
of annexing Milan. No sooner had he ascended the French throne than he
began to act upon this ambition. He descended into Lombardy, overran the
Milanese, sent Lodovico Sforza to die in a French prison, and initiated
the duel between Spain and France for mastery, which ended with the
capture of Francis I. at Pavia, and his final cession of all rights over
Italy to Charles V. by the Treaty of Cambray.

Of all the republics which had conferred luster upon Italy in its
