There were clearly marked causes for this brilliant and patriotic era. The indiscriminate marriages of Henry VIII had thrown more than a shadow of doubt upon the legitimacy of every one of his children. On his death he was succeeded, without serious dispute, by his only son, Edward VI. Edward did not live to manhood, but during his short reign his guardians pushed the land far in the direction of Protestantism. Unfortunately they plundered the common people cruelly and persecuted, though only in two cases to the point of burning, both Catholics and the more extreme Protestants. The early death of Edward left no male heir to the royal house. For the first time in English history there were none but women to claim the crown. Moreover, of these at least four had some show of right. They were Mary, the Catholic daughter of King Henry's first wife, and Elizabeth, his Protestant daughter by Anne Boleyn. Or, if both these were to be considered illegitimate, then came their cousins, Mary Stuart, descended from one of Henry's sisters, and Lady Jane Grey, from another. The friends of Lady Jane tried to raise her to the throne, but only succeeded in bringing her to the scaffold. The Catholic, Mary, was declared the rightful queen and ruled England for five years, during most of which she kept her half-sister Elizabeth in prison. Queen Mary was devoted to her religion. The fires which had burned in Henry's time were kindled again, but now for the torture of Protestants, bishops, and men of mark. Mary wedded the Catholic king and cruel fanatic Philip II of Spain, the most powerful monarch of Europe; so that only to her death and the reign of the persecuted Elizabeth could Protestant Englishmen look for relief. Thus the accession of the learned and coquettish Elizabeth brought far more than a mere promise of youth and pleasure; it was a bursting of the fetters of fear.
