Shortly after the prorogation came a dissolution and another general election. The zeal and strength of the opposition were at the height. The cry for the Exclusion Bill was louder than ever, and with this cry was mingled another cry, which fired the blood of the multitude, but which was heard with regret and alarm by all judicious friends of freedom. Not only the rights of the Duke of York, an avowed Papist, but those of his two daughters, sincere and zealous Protestants, were assailed. It was confidently affirmed that the eldest natural son of the King had been born in wedlock, and was lawful heir to the crown.
Charles, while a wanderer on the Continent, had fallen in at the Hague with Lucy Walters, a Welsh girl of great beauty, but of weak understanding and dissolute manners. She became his mistress, and presented him with a son. A suspicious lover might have had his doubts; for the lady had several admirers, and was not supposed to be cruel to any. Charles, however, readily took her word, and poured forth on little James Crofts, as the boy was then called, an overflowing fondness, such as seemed hardly to belong to that cool and careless nature. Soon after the restoration, the young favourite, who had learned in France the exercises then considered necessary to a fine gentleman, made his appearance at Whitehall. He was lodged in the palace, attended by pages, and permitted to enjoy several distinctions which had till then been confined to princes of the blood royal. He was married, while still in tender youth, to Anne Scott, heiress of the noble house of Buccleuch. He took her name, and received with her hand possession of her ample domains. The estate which he had acquired by this match was popularly estimated at not less than ten thousand pounds a year. Titles, and favours more substantial than titles, were lavished on him. He was made Duke of Monmouth in England, Duke of Buccleuch in Scotland, a Knight of the Garter, Master of the Horse, Commander of the first troop of Life Guards, Chief Justice of Eyre south of Trent, and Chancellor of the University of Cambridge. Nor did he appear to the public unworthy of his high fortunes. His countenance was eminently handsome and engaging, his temper sweet, his manners polite and affable. Though a libertine, he won the hearts of the Puritans. Though he was known to have been privy to the shameful attack on Sir John Coventry, he easily obtained the forgiveness of the Country Party. Even austere moralists owned that, in such a court, strict conjugal fidelity was scarcely to be expected from one who, while a child, had been married to another child. Even patriots were willing to excuse a headstrong boy for visiting with immoderate vengeance an insult offered to his father. And soon the stain left by loose amours and midnight brawls was effaced by honourable exploits. When Charles and Lewis united their forces against Holland, Monmouth commanded the English auxiliaries who were sent to the Continent, and approved himself a gallant soldier and a not unintelligent officer. On his return he found himself the most popular man in the kingdom. Nothing was withheld from him but the crown; nor did even the crown seem to be absolutely beyond his reach. The distinction which had most injudiciously been made between him and the highest nobles had produced evil consequences. When a boy he had been invited to put on his hat in the presence chamber, while Howards and Seymours stood uncovered round him. When foreign princes died, he had mourned for them in the long purple cloak, which no other subject, except the Duke of York and Prince Rupert, was permitted to wear. It was natural that these things should lead him to regard himself as a legitimate prince of the House of Stuart. Charles, even at a ripe age, was devoted to his pleasures and regardless of his dignity. It could hardly be thought incredible that he should at twenty have secretly gone through the form of espousing a lady whose beauty had fascinated him. While Monmouth was still a child, and while the Duke of York still passed for a Protestant, it was rumoured throughout the country, and even in circles which ought to have been well informed, that the King had made Lucy Walters his wife, and that, if every one had his right, her son would be Prince of Wales. Much was said of a certain black box which, according to the vulgar belief, contained the contract of marriage. When Monmouth had returned from the Low Countries with a high character for valour and conduct, and when the Duke of York was known to be a member of a church detested by the great majority of the nation, this idle story became important. For it there was not the slightest evidence.
