The arrival of Mary Stewart in Scotland brings her personality into more intimate relation with that of Elizabeth than before. The problem of finding bridegrooms politically and personally acceptable to the two queens becomes particularly prominent. Arran, flatly declined by Elizabeth, becomes for a time one of her cousin's actual suitors. The Archduke Charles becomes a possible candidate for either. Dudley, still looked upon as Elizabeth's favoured lover, is offered by her to Mary as a husband. Now, too, we first meet with Henry Stewart, Lord Darnley, [Footnote: See Appendix A, iii.] whose mother, Lady Lennox, was daughter of Margaret Tudor by her second husband, the young man himself being a possible successor to the English throne. Being an English as well as a Scottish subject, brought up in England and therefore not, like Mary--whatever her claims by descent--an alien, that technical ground for disputing her succession did not apply to him. He too was mentioned as a possible suitor both for Elizabeth's and for Mary's hand. Then there was Don Carlos, son of Philip of Spain by his first wife, to whom Mary had a political inclination; or again there was for her a possibility of marrying her dead husband's brother, the boy-king Charles IX. of France. Mary herself, it must be remembered, was still some months short of nineteen when she landed at Leith. And it was a matter of grave political importance to Elizabeth, who should be the man to share the Scottish throne. [Sidenote: 1562 Mary in Scotland] Mary's reception was austere not to say brutal on the part of Knox and his friends; but the Earl of Murray (as Lord James Stewart soon after became) and Maitland, confident now in the security of Protestantism, were not disposed to subordinate polities to zealotry. They were ready for a degree of toleration. Their ultimate goal was the union of the crowns; and they wished Mary to repose her confidence on them. They would not press her to ratify the Treaty of Edinburgh, at any rate unless she was formally recognised as heir presumptive of England. Mary, for her part, though holding by her own faith, was not slow to perceive that for the present at least she must not challenge the Reformers. Her first business was conciliation.
