Mary Queen of Scots was one of the most remarkable women who ever presided over the destinies of a nation. She was born at Linlithgow on December 8, 1542, a few days before the death of her father, James V., thus becoming a queen before she was a week old. Her complex personality and varied accomplishments have inspired many and various historians, but it has remained for Major Martin Hume to demonstrate the historical fatality of Mary's love affairs. In "The Love Affairs of Mary Queen of Scots," published in 1903, Major Hume gives a convincing and logical reason for Mary's political failure, inasmuch as it did not spring from her goodness or badness as a woman, but from a certain weakness of character. This epitome has been prepared by Major Hume himself. _I.--Betrothed in her Cradle_ When in the great hall at Worms, on that ever-memorable April day in 1521, before the panic-stricken princes, Luther insolently flung at the emperor his defiance of the mediaeval church, the crash, though all unheard by the ears of men, shook to their base the crumbling foundations upon which, for hundreds of years, the institutions of Europe had rested. The sixteenth century thenceforward was a period of disintegration and reconstruction, in which fresh lines of cleavage between old political associates were opened, new affinities were formed, and the international balance re-adjusted. In the long struggle of the house of Aragon, and its successor, Charles V., with France for the domination of Italy, the only effectual guarantee against England's actively aiding its traditional ally, the ruler of Spain and Flanders, against its traditional enemy, France, was for the latter country to keep a tight hold of its alliance with Scotland, by means of which English force might be diverted at any time. The existence of the Scottish "back door" to England, with the ever probable enemy behind it, had long been a check upon English power, and a humiliation to English kings in their efforts to hold the balance between the Continental rivals. But with the spread of Lutheranism in Germany and Henry VIII.'s defiance of the Papacy, the Catholic powers, drawn together in the face of common danger, found a fresh bond of union in their orthodoxy which partially superseded old rivalries. In these circumstances the English policy, which had aimed at the control of Scottish foreign relations to the exclusion of French influence, became not only desirable as it always had been, but vitally necessary to preserve England's independence.
