After calling attention briefly to the fact that this spirit of revolt manifested itself in other countries, a logical plan of presentation would be first to discuss the ineffectual efforts of the Emperor Charles V and Pope Leo X to check the movement as it spread through Germany, with an explanation of their failures; then to describe the more successful efforts in this direction taken within the church itself and known as the Counter Reformation; and finally to introduce Philip II as the great champion of orthodoxy, devoting his entire energies and the resources of a great empire to the superhuman task of restoring the church to its former position of power and influence. His career calls up Alva’s efforts to subdue the Netherlands, and that heroic figure, William the Silent; and the sailing of the Great Armada. One semi-religious war, if not two, have already been under discussion in connection with these efforts to suppress the revolt, the Dutch War of Independence and the Spanish Armada. Here is apparently the proper place to introduce the other struggles, beginning with the Thirty Years’ War in Germany, then taking up in turn the Huguenot wars in France and the Puritan Revolution in England, and closing the period with the sequel to this last struggle, The Glorious Revolution of 1688. The Thirty Years’ War. It is natural to turn to Germany first in presenting the religious wars because of the greater familiarity of the student with conditions there. The order becomes thereby strictly chronological, as the Schmalkaldic War broke out in 1546; or, in other words, earlier by several years than either of the other struggles. This war gave rise to the Peace of Augsburg, which was a source of so much discontent that it has been counted as one of the great factors in bringing on the main struggle. Among the points which seem to call for special emphasis are the mixture of religious and political causes underlying the struggle, and the general participation of many of the great powers of Western Europe. This fact served to prolong the war and to give it a more European character and a wider significance. It was not merely a question of _cujus regio, ejus religio_, but of important dynastic and territorial interests. The efforts directed toward the overthrow of the power of the Hapsburgs and the peculiar interests of Denmark, Sweden and England in the contest call for special emphasis. The power of the Hapsburgs in the time of Charles V and later can be shown to good advantage by the use of outline maps. At least three great personalities dominate the scene, Wallenstein, Richelieu and Gustavus Adolphus, all of whom furnish rich material for biographical study. Although it is possible to follow the campaigns with an atlas like Putzger, this study is comparatively barren of results except as it throws light upon the military genius of a Wallenstein or on the prowess of “The Lion of the North.” The effects of the war were to be
