In 1564 Mary, as yet fancy-free, was seeking to match herself on purely political grounds. She was not so fastidious as Elizabeth, for she does not seem to have troubled herself at all about personal qualities, if a match seemed otherwise eligible. The Hamiltons pressed Arran upon her. But he was a Protestant. He was not heir to any throne but that of Scotland; and, though a powerful family in Scotland, the Hamiltons could give her no help elsewhere. Philip, who, now that the Guises had become his _protégés_, was less jealous of her designs, wished her to marry his cousin, the Archduke Charles of Austria. But this prince, whom Elizabeth professed to find too much of a Catholic, was, in the eyes of Mary and her more bigoted co-religionists, too nearly a Lutheran; and she doubted whether Philip cared enough for him to risk a war for establishing him and herself upon the English throne. For this reason the husband on whom she had set her heart was Don Carlos, Philip’s own son, a sort of wild beast. But Philip received her overtures doubtfully; the fact being that he could not trust Don Carlos, whom he eventually put to death. Catherine de’ Medici loved Mary as little as she did the other Guises, but the prospect of the Spanish match filled her with such terror that she proposed to make the Scottish Queen her daughter-in-law a second time by a marriage with Charles IX., a lad under thirteen, if she would wait two years for him.
On the other hand, Elizabeth impressed upon Mary that, unless she married a member of some Reformed Church, the English Parliament would certainly demand that her title to the succession, whatever it was, should be declared invalid. The House of Commons was strongly Protestant, and had with difficulty been prevented from addressing the Queen in favour of the succession of Lady Catherine Grey. Apart from religion there was deep irritation against the whole Scotch nation. Sir Ralph Sadler, who had been much employed in Scotland, denounced them as “false, beggarly, and perjured, whom the very stones in the English streets would rise against.” When Elizabeth was dangerously ill in October 1562, the Council discussed whom they should proclaim in the event of her death. Some were for the will of Henry VIII. and Catherine Grey. Others, sick of female rulers, were for taking the Earl of Huntingdon, a descendant of the Duke of Clarence. None were for Mary or Darnley. Mary’s chief friends--Montagu, Northumberland, Westmoreland, and Derby--were not on the Council.
