This king was likely to eclipse the pleasure-loving rivals of France and England, for he had vast power in Europe through inheritance of the great possessions of his house. Castile and Aragon came to Charles through his mother, Joanna, who was the daughter of Ferdinand and Isabella. Naples and Sicily went with Aragon, though, as a matter of fact, they had been appropriated in violation of a treaty. The Low Countries were part of the dominions of Charles' grandmother, Mary of Burgundy, who had married Philip, the Archduke of Austria. When Maximilian of Austria died in 1519, he desired that his grandson should succeed not only to his dominions in Europe, but also to the proud title of Holy Roman Emperor, which was not hereditary. With the treasures of the New World at his disposal, through the discoveries of Christopher Columbus, Charles V had little doubt that he could obtain anything he coveted.
It was soon evident that Charles' claim to the Empire would be disputed by Francis I, who declared, "An he spent three millions of gold he would be Emperor." The French King had a fine army, and money enough to bribe the German princes, in whose hands the power of "electing" lay. Francis' ambassadors travelled from one to another with a train of horses, heavily laden with sumptuous offerings, but these found it quite impossible to bribe Frederick the Wise of Saxony.
Charles did not scruple to use bribery, and he hoped to win Henry of England by flattery and by appealing to him as a kinsman; for his aunt, Catherine of Aragon, was Henry's Queen at that time. The Tudor King had boldly taken for his motto, "Whom I defend is master," but he had secret designs on the Imperial throne himself, and thought either Francis I or Charles V would become far too powerful in Europe if the German electors appointed one of them.
The Pope entered into the struggle because he knew that Charles of Spain would be likely to destroy the peace of Italy by demanding the Duchy of Milan, which was then under French rule. He gave secret advice, therefore, to the German electors to choose one of their own number, and induced them to offer the Imperial rank to Frederick the Wise of Saxony. This prince did not feel strong enough to beat off the attacks of Selim, the ruler of the Ottoman Empire, then threatening the land of Hungary. He refused to become Emperor and suggested that the natural resistance to the East should come from Austria.
Charles, undoubtedly, had Spanish gold that would assist him in this struggle. In 1519 he was invested with the imperial crown and began to dream of further conquests. A quarrel with France followed, both sides having grievances that made friendship impossible at that period. Charles had offended Francis I by promising to aid d'Albert of Navarre to regain his kingdom. He also wished to claim the Duchy of Milan as the Pope had predicted, and was indignant that Burgundy, which had been filched from his grandmother by Louis XI, had never been restored to his family.
Francis renewed an ancient struggle in reclaiming Naples. He was determined not to yield to imperial pride, and sought every means of conciliating Henry VIII of England, who seemed eager to assert himself in Europe. The two monarchs met at the Field of the Cloth of Gold in 1513 and made a great display of friendship. They were both skilled horsemen and showed to advantage in a tournament, having youth and some pretensions to manly beauty in their favour. The meeting between them was costly and did not result as Francis had anticipated, since Charles V had been recently winning a new ally in the person of Cardinal Wolsey, the chief adviser of the young King of England.
Wolsey was ambitious and longed for the supreme honour of the Catholic Church. He believed that he might possibly attain this through the nephew of Catherine of Aragon. He commended Charles to his master, and in the end gained for him an Austrian alliance. There was even some talk of a marriage between the Emperor and the little Princess Mary.
A treaty with the Pope made Charles V more sanguine of success than ever. Leo X belonged to the family of the Medici and hoped to restore the ancient prestige of that house. He was overjoyed to receive Parma and Placentia as a result of his friendship with the ambitious Emperor, and now agreed to the expulsion of the French from Milan on condition that Naples paid a higher tribute to the Papal See.
These arrangements were concluded without reference to Chièvres, the Flemish councillor, whose influence with Charles had once been paramount. Henceforward, the Emperor ruled his scattered empire, relying only upon his own strength and capability. He naturally met with disaffection among his subjects, for the Spaniards were jealous of his preference for the Netherlands, where he had been educated, and the people of Germany resented his long sojourn in Spain, thinking that they were thereby neglected. It would have been impossible for Charles to have led a more active life or to have striven more courageously to retain his hold over far distant countries. He was constantly travelling to the different parts of his empire, and made eleven sea-voyages during his reign—an admirable record in days when voyages were comparatively dangerous.
Charles changed his motto from Nondum to Plus ultra as he proceeded to send fleets across the ocean that the banner of Castile might float proudly on the distant shores of the Pacific. But the war with France was the real interest of the Emperor's life and he pursued it vigorously, obtaining supplies from the Spanish Cortes or legislative authority of Spain. He gained the sympathy of that nation during his residence at Madrid from 1522-9 and pacified the rebellious spirit of the Communes which administered local affairs. His marriage with Isabella of Portugal proved, too, that he would maintain the traditions of the Spanish monarchy.
