On the occasion of each new election to the papacy, it is the custom for all the Christian States to send a solemn embassy to Rome, to renew their oath of allegiance to the Holy Father.Ludovico Sforza conceived the idea that the ambassadors of the four Powers should unite and make their entry into Rome on the same day, appointing one of their envoy, viz.the representative of the King of Naples, to be spokesman for all four.Unluckily, this plan did not agree with the magnificent projects of Piero dei Medici.That proud youth, who had been appointed ambassador of the Florentine Republic, had seen in the mission entrusted to him by his fellow-citizens the means of making a brilliant display of his own wealth.From the day of his nomination onwards, his palace was constantly filled with tailors, jewellers, and merchants of priceless stuffs; magnificent clothes had been made for him, embroidered with precious stones which he had selected from the family treasures.All his jewels, perhaps the richest in Italy, were distributed about the liveries of his pages, and one of them, his favourite, was to wear a collar of pearls valued by itself at 100,000 ducats, or almost, a million of our francs.In his party the Bishop of Arezzo, Gentile, who had once been Lorenzo dei Medici's tutor, was elected as second ambassador, and it was his duty to speak.Now Gentile, who had prepared his speech, counted on his eloquence to charm the ear quite as much as Piero counted on his riches to dazzle the eye.But the eloquence of Gentile would be lost completely if nobody was to speak but the ambassador of the King of Naples; and the magnificence of Piero dei Medici would never be noticed at all if he went to Rome mixed up with all the other ambassadors.These two important interests, compromised by the Duke of Milan's proposition, changed the whole face of Italy.
Ludovico Sforza had already made sure of Ferdinand's promise to conform to the plan he had invented, when the old king, at the solicitation of Piero, suddenly drew back.Sforza found out how this change had come about, and learned that it was Piero's influence that had overmastered his own.He could not disentangle the real motives that had promised the change, and imagined there was some secret league against himself: he attributed the changed political programme to the death of Lorenzo dei Medici.But whatever its cause might be, it was evidently prejudicial to his own interests: Florence, Milan's old ally, was abandoning her for Naples.He resolved to throw a counter weight into the scales; so, betraying to Alexander the policy of Piero and Ferdinand, he proposed to form a defensive and offensive alliance with him and admit the republic of Venice; Duke Hercules IIIof Ferrara was also to be summoned to pronounce for one or other of the two leagues.Alexander VI, wounded by Ferdinand's treatment of himself, accepted Ludovico Sforza's proposition, and an Act of Confederation was signed on the 22nd of April, 1493, by which the new allies pledged themselves to set on foot for the maintenance of the public peace an army of 20,000 horse and 6,000 infantry.
Ferdinand was frightened when he beheld the formation of this league;but he thought he could neutralise its effects by depriving Ludovico Sforza of his regency, which he had already kept beyond the proper time, though as yet he was not strictly an usurper.Although the young Galeazzo, his nephew, had reached the age of two-and-twenty, Ludovico Sforza none the less continued regent.Now Ferdinand definitely proposed to the Duke of Milan that he should resign the sovereign power into the hands of his nephew, on pain of being declared an usurper.
This was a bold stroke; but there was a risk of inciting Ludovico Sforza to start one of those political plots that he was so familiar with, never recoiling from any situation, however dangerous it might be.This was exactly what happened: Sforza, uneasy about his duchy, resolved to threaten Ferdinand's kingdom.
Nothing could be easier: he knew the warlike nations of Charles VIII, and the pretensions of the house of France to the kingdom of Naples.
He sent two ambassadors to invite the young king to claim the rights of Anjou usurped by Aragon; and with a view to reconciling Charles to so distant and hazardous an expedition, offered him a free and friendly passage through his own States.
Such a proposition was welcome to Charles VIII, as we might suppose from our knowledge of his character; a magnificent prospect was opened to him as by an enchanter: what Ludovica Sforza was offering him was virtually the command of the Mediterranean, the protectorship of the whole of Italy; it was an open road, through Naples and Venice, that well might lead to the conquest of Turkey or the Holy Land, if he ever had the fancy to avenge the disasters of Nicapolis and Mansourah.So the proposition was accepted, and a secret alliance was signed, with Count Charles di Belgiojasa and the Count of Cajazza acting for Ludovica Sforza, and the Bishop of St.Malo and Seneschal de Beaucaire far Charles VIII.By this treaty it was agreed:--That the King of France should attempt the conquest of the kingdom of Naples;That the Duke of Milan should grant a passage to the King of France through his territories, and accompany him with five hundred lances;That the Duke of Milan should permit the King of France to send out as many ships of war as he pleased from Genoa;Lastly, that the Duke of Milan should lend the King of France 200,000ducats, payable when he started.
On his side, Charles VIII agreed:--
To defend the personal authority of Ludowico Sforza over the duchy of Milan against anyone who might attempt to turn him out;To keep two hundred French lances always in readiness to help the house of Sforza, at Asti, a town belonging to the Duke of Orleans by the inheritance of his mother, Valentina Visconti;Lastly, to hand over to his ally the principality of Tarentum immediately after the conquest of Naples was effected.
