It would be tedious to read the various wars between Charles and his rival. Each of them gained, at different times, great successes, and each experienced, in turn, the most humiliating reverses. Francis was even taken prisoner at the battle of Pavia, in 1525, and confined in a fortress at Madrid, until he promised to the victors the complete dismemberment of France—an extorted promise he never meant to keep. No sooner had he recovered his liberty, than he violated all his oaths, and Europe was again the scene of fresh hostilities. The passion of revenge was now added to that of ambition, and, as the pope had favored the cause of Francis, the generals of Charles invaded Italy. Rome was taken and sacked by the constable Bourbon, a French noble whom Francis had slighted, and cruelties and outrages were perpetrated by the imperial forces which never disgraced Alaric or Attila.
Charles affected to be filled with grief in view of the victories of his generals, and pretended that they acted without his orders. He employed every artifice to deceive indignant Christendom, and appointed prayers and processions throughout Spain for the recovery of the pope's liberty, which one stroke of his pen could have secured. Thus it was, that the most Catholic and bigoted prince in Europe seized the pope's person, and sacked his city, at the very time when Luther was prosecuting his reform. And this fact shows how much more powerfully the emperor was influenced by political, than by religious considerations. It also shows the providence of God in permitting the only men, who could have arrested the reformation, to spend their strength in battling each other, rather than the heresy which they deplored. Had Charles been less powerful and ambitious, he probably would have contented himself in punishing heretics, and in uniting with his natural ally, the pope, in suppressing every insurrection which had for its object the rights of conscience and the enjoyment of popular liberty.
The war was continued for two years longer between Francis and Charles, with great acrimony, but with various success, both parties being, at one time, strengthened by alliances, and then again weakened by desertions. At last, both parties were exhausted, and were willing to accede to terms which they had previously rejected with disdain. Francis was the most weakened and disheartened, but Charles was the most perplexed. The troubles growing out of the Reformation demanded his attention, and the Turks, at this period a powerful nation, were about invading Austria. The Spaniards murmured at the unusual length of the war, and money was with difficulty obtained.
Hence the peace of Cambray, August 5, 1529; which was very advantageous to Charles, in consequence of the impulsive character of Francis, and his impatience to recover his children, whom he had surrendered to Charles in order to recover his liberty. He agreed to pay two millions of crowns for the ransom of his sons, and renounce his pretensions in the Low Countries and Italy. He, moreover, lost reputation, and the confidence of Europe, by the abandonment of his allies. Charles remained the arbiter of Italy, and was attentive to the interests of all who adhered to him. With less chivalry than his rival, he had infinitely more honor. Cold, sagacious, selfish, and ambitious, he was, however, just, and kept his word. He combined qualities we often see in selfish men—a sort of legal and technical regard to the letter of the law, with the constant violation of its spirit. A Shylock might not enter a false charge upon his books, while he would adhere to a most extortionate bargain.
Charles, after the treaty of Cambray was signed, visited Italy with all the pomp of a conqueror. At Genoa, he honored Doria with many marks of distinction, and bestowed upon the republic new privileges. He settled all his difficulties with Milan, Venice, and Florence, and reëstablished the authority of the Medici. He was then crowned by the pope, whom he had trampled on, as King of Lombardy and Emperor of the Romans, and hastened into Germany, which imperatively required his presence, both on account of dissensions among the princes, which the reformation caused, and the invasion of Austria by three hundred thousand Turks. He resolved to recover the old prerogatives of the emperor of Germany, and crush those opinions which were undermining his authority, as well as the power of Rome, with which his own was identified.
A Diet of the empire was accordingly summoned at Diet of Spires. Spires, in order to take into consideration the state of religion, the main cause of all the disturbances in Germany. It met on the 15th of March, 1529, and the greatest address was required to prevent a civil war. All that Charles could obtain from the assembled princes was, the promise to prevent any further innovations. A decree to that effect was passed, against which, however, the followers of Luther protested, the most powerful of whom were the Elector of Saxony, the Marquis of Brandenburg, the Landgrave of Hesse, the Duke of Lunenburg, the Prince of Anhalt, and the deputies of fourteen imperial cities. This protest gave to them the name of Protestants—a name ever since retained. Soon after, the diet assembled at Augsburg, when the articles of faith among the Protestants were read—known as the Confession of Augsburg—which, however, the emperor opposed. In consequence of his decree, the Protestant princes entered into a league at Smalcalde, (December 22, 1530,) to support one another, and defend their religion. Circumstances continually occurred to convince Charles, that the extirpation of heresy by the sword was impossible in Germany, and moreover, he saw it was for his interest—to which his eye was peculiarly open—to unite all the German provinces in a vigorous confederation. Accordingly after many difficulties, and with great reluctance, terms of pacification were agreed upon at Nuremburg, (1531,) and ratified in the diet at Ratisbon, shortly after, by which it was agreed that no person should be molested in his religion, and that the Protestants, on their part, should assist the emperor in resisting the invasion of the Turks. The Germans, with their customary good faith, furnished all the assistance they promised, and one of the best armies ever raised in Germany, amounting to ninety thousand foot, and thirty thousand horse, took the field, commanded by the emperor in person. But the campaign ended without any memorable event, both parties having erred from excessive caution.
Francis soon availed himself of the difficulties and dangers of his rival, formed an alliance with the Turks, put forth his old claims, courted the favor of the German Protestants, and Hostilities between Charles and Francis. renewed hostilities. He marched towards Italy, and took possession of the dominions of the duke of Savoy, whom the emperor, at this juncture, was unable to assist, on account of his African expedition against the pirate Barbarossa. This noted corsair had built up a great power in Tunis and Algiers, and committed shameful ravages on all Christian nations. Charles landed in Africa with thirty thousand men, took the fortress of Goletta, defeated the pirate's army, captured his capital, and restored the exiled Moorish king to his throne. In the midst of these victories Francis invaded Savoy. Charles was terribly indignant, and loaded his rival with such violent invectives that Francis challenged him to single combat. The challenge was accepted, but the duel was never fought. Charles, in his turn, invaded France, with a large army, for that age—forty thousand foot and ten thousand horse; but the expedition was unfortunate. Francis acted on the defensive with admirable skill, and was fortunate in his general Montmorency, who seemed possessed with the spirit of a Fabius. The emperor, at last, was compelled to return ingloriously, having lost half of his army without having gained a single important advantage. The joy of Francis, however, was embittered by the death of the dauphin, attributed by some to the infamous Catharine de Medicis, wife of the Duke of Orleans, in order to secure the crown to her husband. War did not end with the retreat of Charles, but was continued, with great personal animosity, until mutual exhaustion led to a truce for ten years, concluded at Nice, in 1538. Both parties had exerted their utmost strength, and neither had obtained any signal advantage. Notwithstanding their open and secret enmity, they had an interview shortly after the truce, in which both vied with each other in expressions of esteem and friendship, and in the exhibition of chivalrous courtesies—a miserable mockery, as shown by the violation of the terms of the truce, and the renewal of hostilities in 1541.
