But perhaps the greatest source of danger was from Spain. There were countless reasons why Philip should declare war—religion, the seizure of his treasure by Elizabethan seamen, the treatment of Mary (though this did not at first much concern him), and Spanish repression in the Netherlands. English negotiation with France would be of value to England, if for nothing else, in keeping France and Spain apart. It was hoped, moreover, that once England and France were united, the combination might check Philip in his dealing with the Netherlands and the English Catholics and in the cruelties visited on Englishmen in Spain. But there were grave objections to a marriage. It would introduce a new and unknown element into English councils. Suppose, as a Catholic, the King should join that party; or worse, ally himself with Mary herself, plot the death of Elizabeth and a Catholic restoration. Or suppose he should become king of France? or that his child should be heir to both thrones? The thought of becoming a French dependency was intolerable to England. In any case it would mean a break with Spain and how could England be sure that France was not merely tempting her to that, finally to leave her to face Spain alone? Plainly, marriage was too close and dangerous a union—as for negotiations, that was another matter, and it was simply for the negotiations themselves that Elizabeth entered upon them. This is proved, I think, by her entire policy. Whenever France seems most willing she draws away; but when France seems likely to abandon such fruitless endeavors, she at once becomes affable and yielding. Sometimes her ministers urged her to definite and decided action, but she always managed to find a loop-hole, if either they or circumstance had forced her into too dangerous agreement. France, on the other hand, could not be content with mere negotiations. She, too, had several definite problems. Rent by civil war, with enormously powerful barons on the one side and a clamorous people on the other, while outside the realm stood Spain and England, only too glad to promote and foster her difficulties, the crown was in a struggle for existence as real as that of Elizabeth. To join Spain would be for France to lose her integral existence and to be swallowed up in the maw of the Hapsburgs. Therefore the English alliance was the only refuge. Besides there were many other advantages. It would stop England’s meddling in French affairs and would calm and reassure the Huguenots. But there was the rub: did the Huguenots need to be reassured? Could France safely commit herself to a liberal policy? To Catherine it was not so much that, as the question of her own authority and personal ambition for her family; she had no intention of giving place to the Huguenots any more than she had to the Guises. And so she wavered when the Guises were becoming too powerful, and helped along the marriage; when the Huguenots began to be too authoritative, she frowned on it.
