Some of the principal stipulations of these articles were, that Philip was to have the title of King of England jointly with Mary's title of queen. Mary was also to share with him, in the same way, his titles in Spain. It was agreed that Mary should have the exclusive power of the appointment of officers of government in England, and that no Spaniards should be eligible at all. Particular provisions were made in respect to the children which might result from the marriage, as to how they should inherit rights of government in the two countries. Philip had one son already, by his former wife. This son was to succeed his father in the kingdom of Spain, but the other dominions of Philip on the Continent were to descend to the offspring of this new marriage, in modes minutely specified to fit all possible cases which might occur. The making of all these specifications, however, turned out to be labor lost, as Mary never had children. It was also specially agreed that Philip should not bring Spanish or foreign domestics into the realm, to give uneasiness to the English people; that he would never take the queen out of England, nor carry any of the children away, without the consent of the English nobility; and that, if the queen were to die before him, all his rights and claims of every sort, in respect to England, should forever cease. He also agreed that he would never carry away any of the jewels or other property of the crown, nor suffer any other person to do so. These stipulations, guarding so carefully the rights of Mary and of England, were intended to satisfy the English people, and remove their objections to the match. They produced some effect, but the hostility was too deeply seated to be so easily allayed. It grew, on the contrary, more and more threatening, until at length a conspiracy was formed by a number of influential and powerful men, and a plan of open rebellion organized. The leader in this plan was Sir Thomas Wyatt, and the outbreak which followed is known in history as Wyatt's rebellion. Another of the leaders was the Duke of Suffolk, who, it will be recollected, was the father of Lady Jane Grey. This led people to suppose that the plan of the conspirators was not merely to prevent the consummation of the Spanish match, but to depose Queen Mary entirely, and to raise the Lady Jane to the throne. However this may be, an extensive and formidable conspiracy was formed. There were to have been several risings in different parts of the kingdom. They all failed except the one which Wyatt himself was to head, which was in Kent, in the southeastern part of the country. This succeeded so far, at least, that a considerable force was collected, and began to advance toward London from the southern side.
