As an introduction to the subject, of which this volume professes more especially to treat, I purpose to give a sketch of the proceedings of the emissaries of Rome in this country, during the long reign of Queen Elizabeth. Queen Mary died A.D. 1558, when her sister Elizabeth succeeded her on the throne. Paul IV. at this time occupied the papal chair: but in less than a year after her accession he was removed by death, and was succeeded by Pius IV. Both these pontiffs were quiet and moderate men, compared with several of those who came after them. At all events, they did not proceed to those extremities to which their successors resorted. There were, indeed, parties in the court of Rome, who laboured to induce these pontiffs to excommunicate the queen, as a heretic and a usurper; but recollecting the fatal consequences which had issued from the hasty proceedings of Clement against Henry VIII., or, probably imagining that greater benefits would result from gentle than from violent measures, they pursued a moderate course, exhorting the queen to return to her allegiance to the see of Rome, and even making promises of concessions respecting the reformation. In 1566, Pius V. was promoted to the papal chair. In a very brief space he gave indications of a departure from the moderate councils of his two immediate predecessors. The efforts of Philip II. of Spain were also, during the early years of this reign, directed to the same object with those of Paul IV. and Pius IV. The king was anxious to marry Elizabeth, in order that he might exercise his influence in England; and as long as he could entertain a hope that his wishes would be realized, he seconded the moderate measures of the Roman pontiff. His expectations on this subject were destined to disappointment; when perceiving that a marriage with the queen was out of the question, he directed his attention towards the accomplishment of his designs on this country by other means than those of treaty and diplomacy. As soon as Pius V. was fixed in the papal chair a different line of policy, therefore, was pursued towards England. Some few years, indeed, elapsed before the queen was actually excommunicated; but conspiracies and treasons were contrived at Rome, with a view to their execution, as soon as suitable persons could be found for the purpose.
