The French King was indeed freed from the necessity of ceding Burgundy, and regained his sons, who had been left hostages in the hands of Charles, in return for a sum of money. The other terms were, however, sufficiently humiliating. Not only did Francis surrender all claims to Italy, and to the overlordship of Artois and Flanders; but he had also to abandon his allies; he even undertook, if necessary, to force the Venetians to disgorge the conquests they had lately made on the Neapolitan coast, and this in the face of his solemn engagement on the honour of a King to include them in any treaty which he might make. Francis, it must be confessed, rated a King’s word rather low. The marriage, first arranged at the Treaty of Madrid, was ratified; it was hoped that if Eleonora, the widowed sister of Charles, were wedded to Francis, the family tie might serve to heal the personal enmity of these two sovereigns, whose rivalry had plunged Europe into an eight years’ war. | Charles leaves Spain for Italy. August, 1529. | Settlement of Italian affairs. Before the negotiations had been brought to a successful issue, Charles had left Spain. It was his earnest desire to finish the war himself, and to receive the imperial crown from the hands of the Pope. It was at Piacenza therefore that he finally ratified the treaty. Italy was now at the mercy of Charles. He was, however, wise enough to adopt a conciliatory policy towards all her States, except the Republic of Florence. Venice was indeed forced to surrender to Charles her conquests on the east coast of Naples, and to restore Ravenna and Cervia to the Pope, but was not further punished. To Francesco Maria Sforza was left the duchy of Milan, with the exception of Monza, which was granted to Antonio de Leyva, Charles’ brave general, and of the citadels of Milan and Como, which Charles kept in his own hands.[48] This policy had its reward. By a treaty of December 23, 1529, Venice and Sforza joined the Pope in contracting a defensive alliance with Charles; while Savoy was strengthened as an outpost against France by the acquisition of the county of Asti. The affairs of Florence had yet to be settled. Charles would gladly have found some middle course. But the Florentines refused to readmit the Medici even as private citizens, and Clement insisted that they should be restored to power. The city, strengthened by the fortifications designed by Michael Angelo, and defended by the militia formed after the advice of Machiavelli, stood an eight months’ siege, during which the Prince of Orange, Charles’ general, was killed. No one, however, came to the aid of the unfortunate Republic, which was forced to accept as Duke, Alessandro, the cousin of the Pope, who had married Margaret, the illegitimate daughter of the Emperor.[49] | Charles crowned Emperor at Bologna.
