This pride had its fall, however, as in 1677 the boy-king Charles, at the age of fifteen, which had been fixed as his majority, was made to see that his mother was working against the best interests of his subjects; and he escaped from the honorable captivity in which he had been held at the palace, and gave himself up to his half-brother, Don Juan, who was only too ready to seize this advantage against the hostile queen. Manana was imprisoned in a convent in Toledo, Valenzuela was exiled to the Philippines, and Don Juan, as prime minister, prepared to restore public confidence. In line with his former policy, he made a clean sweep of all the members of the Austrian party, and then began to prepare the way for a French marriage, to strengthen the friendly feeling of the powerful Louis XIV., who had been married to a Spanish wife. Scarcely had the promise for this marriage between Louis's niece Marie Louise and the half-witted Charles been made, when, suddenly, Don Juan sickened and died, and the queen-mother Mariana was again in power. There were dark hints of poison; it was insinuated that Mariana knew more of the affair than she would be willing to reveal; but, whatever the facts, there was no proof, and there was no opportunity for accusations.

Her beauty made an immediate impression upon the feeble mind of her consort; but she spurned his advances, made a jest of his pathetic passion for her, and was soon deep in a life of dissipation. Mariana, as the older woman, might have checked this impulsive nature; but she aided rather than hindered the downfall of the little queen, looked with but feigned disapproval upon the men who sought her facile favors, and, after a swift decade, saw her die, without a murmur of regret. Again there were whispers of poison, but Mariana was still in power, and she lost no time in planning again for Austrian ascendency and an Austrian succession. Once more the puppet king was accepted as a husband, and this time by the Princess Anne of Neuburg, a daughter of the elector-palatine, and sister of the empress, though, in justice to Anne, it should be said that she was an unwilling bride and merely came as Marie Louise had
