This was the way King Philip reasoned as well as the English. Then he thought: "Elizabeth is a wise, shrewd woman, and she can see that with France and Scotland against her, her only hope is to ally herself with Spain. The only way to be sure of Spain's support is to marry me or some true friend of mine." As for her Protestantism, he did not think that matter of any great importance, for he believed that she would rather be sure of her throne than of her church.
When Elizabeth became queen, she had sent, as was the custom, a letter to the various rulers of Europe, formally announcing her accession. Philip's plans were made before the letter reached him. He had concluded that his only safe course was to marry her himself. He wrote to his ambassador, Count de Feria, and explained why he had come to such a conclusion. It was a great sacrifice, he said, for it would not be easy to rule England in addition to his other domains, and Elizabeth must not be so unreasonable as to expect him to spend much of his time with her. She must give up her Protestant notions, of course, become a Catholic, and agree to uphold the Catholic faith in her country. To marry the sister of his dead wife was against the law of the church, but he was sure that he could induce the Pope to grant special permission.
Philip's reply to Elizabeth's announcement was an ardent letter begging her in most eloquent terms to become his wife. The queen met his request with the gravest courtesy, thanked him for the honor that he had done her, and told him how fully she realized of what advantage such a splendid alliance would be to her. Philip wrote again and again; he told her how highly he thought of her abilities and merits, and what a charming, fascinating woman she was. Elizabeth was shrewd enough to understand why this keen politician was so eager for the marriage, but she answered his letters with the utmost politeness, and when other excuses failed, she told him that she could not make any plans concerning marriage without consulting Parliament, and that body was not yet in session. She mischievously allowed her ladies to see his glowing epistles, but perhaps she may be pardoned for this offence, inasmuch as Count de Feria had foolishly shown the king's letter, and Elizabeth knew precisely what Philip had said about the great sacrifice he was making in wedding her. Philip was so sure she would marry him that he sent envoys to Rome to get the Pope's permission, but before they could return, a final letter came from the queen, refusing to take him for her husband. The Spaniard was easily consoled, for within a month he married the daughter of the French king.
