readily permit an arbitrary and capricious enactment to disturb, Mary Queen of Scots, granddaughter of Margaret, was the indisputable representative of her royal progenitors, and the next in succession to Elizabeth. _Elizabeth's unwillingness to decide the succession, or to marry._--This reversion, indeed, after a youthful princess, might well appear rather an improbable contingency. It was to be expected that a fertile marriage would defeat all speculations about her inheritance; nor had Elizabeth been many weeks on the throne, before this began to occupy her subjects' minds.[182] Among several who were named, two very soon became the prominent candidates for her favour, the Archduke Charles, son of the Emperor Ferdinand, and Lord Robert Dudley, sometime after created Earl of Leicester; one recommended by his dignity and alliances, the other by her own evident partiality. She gave at the outset so little encouragement to the former proposal, that Leicester's ambition did not appear extravagant.[183] But her ablest counsellors who knew his vices, and her greatest peers who thought his nobility recent and ill acquired, deprecated so unworthy a connection.[184] Few will pretend to explore the labyrinths of Elizabeth's heart; yet we may almost conclude that her passion for this favourite kept up a struggle against her wisdom for the first seven or eight years of her reign. Meantime she still continued unmarried; and those expressions she had so early used, of her resolution to live and die a virgin, began to appear less like coy affectation than at first. Never had a sovereign's marriage been more desirable for a kingdom. Cecil, aware how important it was that the queen should marry, but dreading her union with Leicester, contrived, about the end of 1564, to renew the treaty with the Archduke Charles.[185] During this negotiation, which lasted from two to three years, she showed not a little of that evasive and dissembling coquetry which was to be more fully displayed on subsequent occasions.[186] Leicester deemed himself so much interested as to quarrel with those who manifested any zeal for the Austrian marriage; but his mistress gradually overcame her misplaced inclinations; and from the time when that connection was broken off, his prospects of becoming her husband seem rapidly to have vanished away. The pretext made for relinquishing this treaty with the archduke was Elizabeth's constant refusal to tolerate the exercise of his religion; a difficulty which, whether real or ostensible, recurred in all her subsequent negotiations of a similar nature.[187]
