At this moment, the death of Sforza of Milan (24th October 1535), altered the position of affairs. He was the last direct descendant of the House, and Milan accordingly fell to Charles as suzerain.Death of Sforza. Oct. 24, 1535. The Emperor, who had only just concluded the expedition against Barbarossa, was anxious to gain time, and amused the King with negotiations. Francis demanded Milan for Henry, Duke of Orleans, his second son. Charles offered to grant it to the Duke of Angoulême, the third son of the French King, on condition of his marrying an Austrian princess.

Meanwhile the French had crossed the Alps by the Pass of Susa, and occupied Turin (April, 1536). Charles now threw off the mask.The French cross the Alps and occupy Turin. April, 1536. He denounced the King as a faithless man, the ally of heretic and infidel, and challenged him to personal combat, suggesting that Burgundy and Milan should be the prize of victory. On this being refused, Antonio de Leyva crossed the Sesia at the head of the imperial troops (May, 1536). The Marquis of Saluzzo, who commanded the French army in Piedmont, deserted to the Emperor, and Charles,Charles makes an unsuccessful attack on Provence. July–Sept. 1536. neglecting to secure Turin, pressed on into Provence in the hopes of bringing Francis to a decisive engagement. The French, contrary to their usual practice, adopted a Fabian policy. They devastated the country as they retired, and threw themselves into strong positions at Avignon and Valence. Unable to storm these places, the imperial army began to suffer from want and disease, to which de Leyva himself succumbed (September 10, 1536). Charles, despairing of success, was forced to evacuate the country (September 23), and retired to Spain ‘to bury there his honour which he had lost in Provence.’

The attack of the Imperialists on Picardy and Languedoc had been equally unsuccessful, although, during the campaign in Picardy,Campaigns in Picardy, Languedoc, Artois, and Piedmont. Francis lost Robert de la Marck, ‘Le Jeune Aventureux,’ the military companion of his youth, and the author of the Memoirs which bear his name. In 1537, the French invaded Artois. The war in Piedmont still continued, and Solyman, in pursuance of his recent treaty, sent Barbarossa to attack the coasts of Naples, while, shortly after, he invaded Hungary in person, and defeated Ferdinand[51] at Essek (October 8).Solyman defeats Ferdinand at Essek. Oct. 1537. This alliance of the French with Solyman excited the indignation of Europe. Paul III., who had hitherto adopted a neutral attitude, now intervened as mediator. Francis was not unwilling to treat, and Charles had nothing to hope from a continuance of the war.Revolt of Ghent, 1537. The Lutherans were daily gaining strength; the attack of the Moslem was threatening the imperial hold on Naples; while in the north, the people of Ghent had risen against the taxes imposed by the Regent of the Netherlands (1537).

Accordingly, a truce for ten years was made at Nice (June 18, 1538). By that truce the Peace of Cambray was confirmed. The rivals abandoned their allies, and each was to retain the conquests they had made.The Truce of Nice. June 18, 1538. Thus the Duke of Savoy was made the scapegoat. Savoy and two-thirds of Piedmont were retained by Francis, the Swiss henceforth occupied the district of Vaud, and the Emperor held the rest, with the exception of Nice, which alone was left to the unfortunate Duke. A conference at Aigues Mortes followed (July 1538), at which Francis, hoping to gain by conciliation what he had failed to attain by arms, adopted a most friendly attitude towards Charles. The Marshal de Montmorency, who had gained a great reputation in the campaign of Provence, urged the King to ally himself with Charles, and even suggested a joint invasion of England, where the anti-papal measures of Henry VIII. and the execution of Bishop Fisher and Sir Thomas More had excited much discontent. Although Francis stopped short of this, he turned a deaf ear to the petition for aid which the citizens of Ghent sent him, and shortly after gave the Emperor a free passage thither through France.

On the approach of Charles, the city, disappointed in its expectation of French assistance, submitted (February 6, 1540), to pay dearly for its rashness.Charles suppresses the revolt at Ghent. Feb. 6, 1540. Fourteen of the leading citizens were executed, the civic privileges were forfeited, a heavy fine was levied, and a garrison admitted within the walls. This completed the ruin of the ancient city, whose commercial supremacy, with that of Bruges, had already passed to Antwerp in consequence of the revolution in the routes of commerce caused by the discovery of the way round the Cape.

Now for a moment it appeared as if King and Emperor would lay aside their long rivalry and unite to resist both heretic and Turk. That Charles entertained such an idea is not to be wondered at. Solyman, encouraged by the French alliance, was menacing Hungary once more, and Barbarossa was still threatening the Mediterranean from Algiers.Advance of Protestantism in Germany. Nor was the danger less at home. Protestantism had made notable advances since the Peace of Nuremberg, 1532. In 1534, Duke Ulrich of Wurtemberg was restored to his duchy, from which he had been driven by the Suabian League in 1519, and which had been granted to Ferdinand, Charles’ brother. The restoration was effected by Philip of Hesse, who defeated the troops of Ferdinand at the battle of Laufen (May 1534), but it was also approved of by John Elector of Trèves, who, although Catholic, was glad to see the House of Hapsburg humbled. Duke Ulrich forthwith established Protestantism in his duchy; the University of Tübingen became the stronghold of the Reformers, and a wedge was driven into the phalanx of Catholic states in South Germany.

In the north, indeed, the outbreak of the Anabaptist revolution at Münster, under John of Leyden, in the spring of 1534, had threatened to compromise the Lutheran party.The Anabaptists at Münster, 1534. This fanatic, who united unbridled licentiousness with strange religious views, attempted to establish a kind of socialistic state of which he proclaimed himself prophet and king. But only the most heated partisanship could find any connection between the views of Luther and of this wild fanatic. As had been the case with the Peasants’ Revolt, Philip of Hesse, one of the most prominent of the leaguers of Schmalkalde, rallied to the cause of order. John of Leyden was executed, his followers dispersed, and Münster restored to its bishop, 1535. Purged from any complicity with the Anabaptists by the suppression of the revolt, the Lutherans continued to make fresh converts in the north of Germany. In the year 1535 Joachim I., Elector of Brandenburg, and in 1539 George, Duke of Saxony, of the Albertine branch of the house, both staunch Catholics, died.George, Duke of Saxony, and Joachim I., Elector of Brandenburg, die and are succeeded by Henry and Joachim II. 1535–1539. Of their successors, Henry of Saxony actually embraced the Lutheran creed, and Joachim II. adopted a conciliatory policy; while his younger brother John, Margrave of the Neumark, became a devoted adherent of the new opinions. Many other smaller princes followed, and, by the close of the year 1539, the only important Catholic states were those of Austria, Bavaria, the Palatinate, the Duchy of Brunswick-Wolfenbüttel, and the three ecclesiastical Electorates; moreover, the Elector of Cologne, Herman von der Wied, was known to be wavering. Shortly after, both he and the Elector-Palatine embraced the Protestant cause.

The crisis demanded instant action. But this was impossible unless the neutrality of France could be secured. Charles accordingly offered the hand of his eldest daughter to the third son of Francis,Charles anxious for a free hand, makes unsuccessful advances to Francis. who, by the death of the dauphin during the campaign in Provence, had now become the Duke of Orleans. He promised to cede to the Duke Franche-Comté and the Netherlands, if Francis, on his part, would grant to him the duchy of Burgundy, abandon all claim to Milan and to the suzerainty of Flanders, and restore the conquests in Savoy and Piedmont to the Duke of Savoy. This would have meant the revival of the old dukedom of Burgundy, but as a fief of the Empire, and it is doubtful whether in any case Francis would have acquiesced in the final loss, not only of his conquests in Piedmont, but also of Milan. In short, the claims on Italy prevented any agreement. After tedious haggling as to whether the Duke of Orleans should have instant possession, and whether the territories should revert to Charles in the event of the Duke’s death without issue, Charles invested Philip, his son, with the duchy of Milan (October 1540), and Francis determined to appeal to arms once more.

With the prospect of war before him, the Emperor recognised the impossibility of using force against the Protestants.Attempted reconciliation with Protestants at Diet of Ratisbon, 1541. Reconciliation, if possible on the basis of comprehension, was the only alternative; and for that purpose he summoned the Diet of Ratisbon, in the spring of 1541. For a moment the chances of reconciliation seemed bright. There had risen of late in Italy a party of reform, led by Reginald Pole, then a fugitive from England, the Venetian Contarini, at this moment the papal legate in Germany, and Morone, Bishop of Modena. This group of literary men, who represented the reaction against the sceptical spirit which had dominated Italy during the days of Leo X., approached very closely to Luther’s views on the doctrine of Justification, and were as eager as he to reform the abuses which disfigured the Church of Rome. Even Paul III. declared himself desirous of doing something. At Ratisbon, a conference of theologians was held, under the presidency of Granvelle, at which Melanchthon, Bucer, and Dr. Eck,[52] Luther’s old opponent, appeared, and an agreement was come to on three of the articles of controversy—Original Sin, Redemption, and Justification. In the Diet itself, the majority of the Electors and of the deputies of the cities declared themselves in favour of this agreement, and Pole rejoiced at the approach of peace and concord. But these hopes were not to be realised. In the Chamber of Princes the opposition was very formidable. The Pope insisted that his supremacy and the Romish view of the Sacraments should be accepted, and Luther could not bring himself to believe in the sincerity of the Catholics. Even if the question had been untrammelled by political considerations, it is very doubtful whether any satisfactory conclusion could have been arrived at, and politics could not be excluded. Reconciliation with the Protestants would make Charles too powerful, as master of a reunited Germany, not to meet with strenuous opposition, both within and without the Empire. Francis and the Pope brought their intrigues to bear on the Princes, many of whom were jealous of Hapsburg influence and dreaded the loss of their political privileges. In vain did the Emperor suggest that the articles on which the theologians had agreed should be accepted for the present, and that, with regard to others, differences of opinion should be tolerated on either side. The agreement was rejected by the Chamber of Princes, much to Charles’ indignation. Thus failed the last chance of a reconciliation between the two religious parties—wrecked on political rivalries—a reconciliation which might have altered the history of Germany and even of Europe. Yet, even so, the Protestants gained much. Charles, anxious for their support during the coming struggle, issued a declaration by which the enforcement of the Recess of Augsburg was still further delayed. Those who had secularised ecclesiastical property were permitted to retain it until the final settlement; Lutherans were to be admitted as assessors to the Imperial Chamber; and, until the meeting of a General Council, no one was to be prevented from adopting Lutheranism. So confident were the Protestants in the strength of their cause, that when the Duke of Brunswick attempted, contrary to this Recess, to force the decisions of the Imperial Chamber on Goslar, he was driven from his duchy by the League of Schmalkalde (summer of 1542), and the Catholics thus lost the only important lay principality which they held in Northern Germany.

While Francis had been doing his utmost to perpetuate the religious divisions in Germany, he had been diligently preparing for war. The Marshal Montmorency, who had advocated friendship with Charles, was disgraced;Francis again declares war. July 1541. alliances were eagerly sought for; and finally, the assassination of the French agent as he was passing through the Milanese on his way to Constantinople (July 3, 1541), gave the French King a decent pretext for breaking the truce of Nice. War, however, was not actually declared till 1542. During the interval Charles suffered two disasters at the hands of the Mahometans. In Hungary, Solyman, marching to the support of the son of Zapolya (who had died in 1540), inflicted a crushing defeat on Ferdinand at Buda (July 30, 1541), and in October, an expedition which the Emperor led in person against Barbarossa in Algiers failed, chiefly owing to wild weather on the African coasts.
