Modern Europe, in the sense in which we understand the term, dates from the last quarter of the Fifteenth Century. Then England ceased to attempt permanent conquests on the continent. Then Spain assumed European rank and definite position. But two powers then began especially to show themselves, and to play parts which both have maintained down to the present time. The one was France, which then ceased to dread English invasions, from the effects of which she was rapidly recovering, whereby she was left to employ her energies on foreign fields. The other was the _House of Austria_, which, by a series of fortunate marriages, became, in the short period of forty years, the most powerful family the modern world has ever known. On the day when Maximilian, son of Frederick III., Emperor of Germany, wedded Mary of Burgundy, daughter of Charles the Bold, the rivalry between France and the Austrian family began. Philip, son of that marriage, married Juana, daughter of Ferdinand and Isabella; and their son, Charles I. of the Spains, became Charles V. of Germany. Thus there centred in his person a degree of power such as no other sovereign could boast, and which alone would have sufficed to make him the rival of the King of France, Francis I., had no personal feeling entered into the relations between them. But such feeling existed, and grew out of their competition for the imperial crown. The previous ill-will between the Valois and the Hapsburg was greatly increased, and assumed such force as permanently to color the course of European history from that day to this. The rivalry of Charles and Francis was the cause of many contests, and the French monarch, though he was "The Most Christian King," in the opinion of some, more than once aided, or offered to aid, the German Protestants against the Emperor. To Philip II. and Henry II. the rivalry of their fathers descended as an inheritance. It was in their warfare that the Battle of St. Quentin was fought. The progress of the Reformation led monarchs in those days to take a view of affairs not much unlike that which monarchs of this century took in the days of the Holy Alliance, and after the revolution of 1830. The hatred of Protestantism led the two kings to draw together, though Henry II. had had no mean part in that work which had enabled the Protestant Maurice of Saxony to render abortive all the plans of Charles V. for the full restoration of Catholicism in Germany. During the thirty years that followed the death of Henry II., the dissensions of France had rendered her unable to contend with the House of Austria, then principally represented by the Spanish branch of that family; and Philip II. at one time thought of obtaining the crown of that country for a member of his own house. But no sooner had Henry IV. ascended the French throne, and established himself firmly thereon, than the rivalry of France and Austria became as clearly pronounced as it had
