It was obvious that the countries newly strengthened, the countries growing in unity and concentration and superfluous forces, would encroach upon those that were demoralised and weakened. By strict reason of State, this was not the policy of France; for the French frontiers were assigned by nature everywhere but in the north-east. There the country was open, the enemy's territory approached the capital; and the true line of expansion was towards Antwerp, or Liege, or Strasburg. But the French were invited into Italy with promise of welcome, because the Angevin claim to Naples, defeated in 1462, had passed to the King of France. The Aragonese, who had been successful in resisting it, was not legitimate, and had been compelled again to struggle for existence by the Rising of the Barons. The rising was suppressed; the discontented Neapolitans went into exile; and they were now in France, prophesying easy triumphs if Charles VIII would extend his hand to take the greatness that belonged to the heir of the house of Anjou. They were followed by the most important of the Italian Cardinals, Della Rovere, nephew of a former Pope, himself afterwards the most famous pontiff who had appeared for centuries. Armed with the secrets of the Conclave, the Cardinal insisted that Alexander VI should be deposed, on the ground that he had paid for the papacy in ascertainable sums of money and money's worth; whereas spiritual office obtained in that way was ipso facto void. The advent of the French, heralded by the passionate eloquence of Savonarola, was also hailed by Florence and its dependencies, in their impatience of the Medicean rule, now that it had dropped from the hands of the illustrious Lorenzo into those of his less competent son. Lodovico Sforza, the Regent of Milan, was also among those who called in the French, as he had a family quarrel with Naples. His father, Francesco, the most successful of the Condottieri, who acquired the Milanese by marriage with a Visconti, is known by that significant saying: "May God defend me from my friends. From my enemies I can defend myself." As the Duke of Orleans also descended from the Visconti, Lodovico wished to divert the French to the more alluring prospect of Naples.
