That the Duke of York should have concurred in the design of degrading that crown which it was probable that he would himself one day wear may seem more extraordinary. For his nature was haughty and imperious; and, indeed, he continued to the very last to show, by occasional starts and struggles, his impatience of the French yoke. But he was almost as much debased by superstition as his brother by indolence and vice. James was now a Roman Catholic. Religious bigotry had become the dominant sentiment of his narrow and stubborn mind, and had so mingled itself with his love of rule, that the two passions could hardly be distinguished from each other. It seemed highly improbable that, without foreign aid, he would be able to obtain ascendency, or even toleration, for his own faith: and he was in a temper to see nothing humiliating in any step which might promote the interests of the true Church. A negotiation was opened which lasted during several months. The chief agent between the English and French courts was the beautiful, graceful, and intelligent Henrietta, Duchess of Orleans, sister of Charles, sister in law of Lewis, and a favourite with both. The King of England offered to declare himself a Roman Catholic, to dissolve the Triple Alliance, and to join with France against Holland, if France would engage to lend him such military and pecuniary aid as might make him independent of his parliament. Lewis at first affected to receive these propositions coolly, and at length agreed to them with the air of a man who is conferring a great favour: but in truth, the course which he had resolved to take was one by which he might gain and could not lose.
