The question, thus, was very complicated. It branched into extensive ramifications, which opened a wide field of debate, and led to endless controversies. It is not probable, however, that Mary Queen of Scots, or her friends, gave themselves much trouble about the legal points at issue. She and they were all Catholics, and it was sufficient for them to know that the Holy Father at Rome had sanctioned the marriage of Catharine, and that that marriage, if allowed to stand, made her the Queen of England. She was at this time in France. She had been sent there at a very early period of her life, to escape the troubles of her native land, and also to be educated. She was a gentle and beautiful child, and as she grew up amid the gay scenes and festivities of Paris, she became a very great favorite, being universally beloved. She married at length, though while she was still quite young, the son of the French king. Her young husband became king himself soon afterward, on account of his father's being killed, in a very remarkable manner, at a tournament; and thus Mary, Queen of Scots before, became also Queen of France now. All these events, passed over thus very summarily here, are narrated in full detail in the History of Mary Queen of Scots pertaining to this series. While Mary was thus residing in France as the wife of the king, she was surrounded by a very large and influential circle, who were Catholics like herself, and who were also enemies of Elizabeth and of England, and glad to find any pretext for disturbing her reign. These persons brought forward Mary's claim. They persuaded Mary that she was fairly entitled to the English crown. They awakened her youthful ambition, and excited strong desires in her heart to attain to the high elevation of Queen of England. Mary at length assumed the title in some of her official acts, and combined the arms of England with those of Scotland in the escutcheons with which her furniture and her plate were emblazoned. When Queen Elizabeth learned that Mary was advancing such pretensions to her crown, she was made very uneasy by it. There was, perhaps, no immediate danger, but then there was a very large Catholic party in England, and they would naturally espouse Mary's cause and they might, at some future time, gather strength so as to make Elizabeth a great deal of trouble. She accordingly sent an embassador over to France to remonstrate against Mary's advancing these pretensions. But she could get no satisfactory reply. Mary would not disavow her claim to Elizabeth's crown, nor would she directly assert it. Elizabeth, then, knowing that all her danger lay in the power and influence of her own Catholic subjects, went to work, very cautiously and warily, but in a very extended and efficient way, to establish the Reformation, and to undermine and destroy all traces of Catholic power. She proceeded in this work with great circumspection, so as not to excite opposition or alarm.
