Since nothing so much strengthens any government as an unsuccessful endeavour to subvert it, it may be thought that the complete failure of the rebellion under the Earls of Northumberland and Westmoreland, with the detection and punishment of the Duke of Norfolk, rendered Elizabeth's throne more secure. But those events revealed the number of her enemies, or at least of those in whom no confidence could be reposed. The rebellion, though provided against by the ministry, and headed by two peers of great family but no personal weight, had not only assumed for a time a most formidable aspect in the north, but caused many to waver in other parts of the kingdom.[206] Even in Norfolk, an eminently protestant county, there was a slight insurrection in 1570, out of attachment to the duke.[207] If her greatest subject could thus be led astray from his faith and loyalty, if others not less near to her councils could unite with him in measures so contrary to her wishes and interests, on whom was she firmly to rely? Who, especially, could be trusted, were she to be snatched away from the world, for the maintenance of the protestant establishment under a yet unknown successor? This was the manifest and principal danger that her counsellors had to dread. Her own great reputation, and the respectful attachment of her people, might give reason to hope that no machinations would be successful against her crown; but let us reflect in what situation the kingdom would have been left by her death in a sudden illness, such as she had more than once experienced in earlier years, and again in 1571. "You must think," Lord Burleigh writes to Walsingham, on that occasion, "such a matter would drive me to the end of my wits." And Sir Thomas Smith expresses his fears in equally strong language.[208] Such statesmen do not entertain apprehensions lightly. Whom, in truth, could her privy council, on such an event, have resolved to proclaim? The house of Suffolk, had its right been more generally recognised than it was (Lady Catherine being now dead), presented no undoubted heir. The young King of Scotland, an alien and an infant, could only have reigned through a regency; and it might have been difficult to have selected from the English nobility a fit person to undertake that office, or at least one in whose elevation the rest would have acquiesced. It appears most probable that the numerous and powerful faction who had promoted Norfolk's union with Mary would have contrived again to remove her from her prison to the throne. Of such a revolution the disgrace of Cecil and of Elizabeth's wisest ministers must have been the immediate consequence; and it is probable that the restoration of the catholic worship would have ensued. These apprehensions prompted Cecil, Walsingham, and Smith to press the queen's marriage with the Duke of Anjou far more earnestly than would otherwise have appeared consistent with her interests.
