We have in the preceding chapters sought to give a general view of the social life, together with the inner political and economic movements, of Germany during that closing period of the Middle Ages which is generally known as the era of the Reformation. With the definite establishment of the Reformation and of the new political and economic conditions that came with it in many of the rising States of Germany, the Middle Ages may be considered as definitely coming to an end, notwithstanding that, of course, a considerable body of mediæval conditions of social, political, and economic life continued to survive all over Europe, and certainly not least in Germany.
We have now to take a general and, so to say, panoramic view embracing three centuries and a half, dating from approximately the middle of the sixteenth century to the present time. Our presentation, owing to exigencies of space, will necessarily take the form of a mere sketch of events and general tendencies, but a sketch that will, we hope, be sufficient to connect periods and to enable the reader to understand better than before the forces that have built up modern Germany and have moulded the national character. In this long period of more than three centuries there are two world-historic events, or rather series of events, which stand out in bold relief as the causes which have moulded Germany directly, and the whole of Europe indirectly, up to the present day. These two epoch-making historical factors are (1) the Thirty Years' War and (2) the Rise of the Prussian Monarchy.
Owing to the success of Protestantism, with its two forms of Lutheranism and Calvinism in various German territories, the friction became chronic between Catholic and Protestant interests throughout the length and breadth of Central Europe. The Emperor himself was chosen, as we know, by three ecclesiastical electors, the Archbishops of Köln, Trier, and Mainz, and by four princes, the Pfalzgraf, called in English the Elector Palatine, the Markgraves of Saxony and Brandenburg, and the King of Bohemia. The princes and other potentates, owing immediate allegiance to the empire alone, were practically independent sovereigns. The Reichstag, instituted in the fifteenth century, attendance at which was strictly limited to these immediate vassals of the empire, had proved of little effect. This was shown when in the middle of the sixteenth century Protestantism had established itself in the favour of the mass of the German peoples. It was vetoed by the Reichstag, with its powerful contingent of ecclesiastical members. Of course here the economic side of the question played a great part. The ecclesiastical potentates and those favourable to them dreaded the spread of Protestantism in view of the secularization of religious domains and fiefs. This, notwithstanding that there were not wanting bishops and abbots themselves who were not indisposed, as princes of the empire, to appropriate the Church lands, of which they were the trustees, for their own personal possessions. After a short civil war an arrangement was come to at the Treaty of Passau in 1552, which was in the main ratified by the Reichstag held at Augsburg in 1555 (the so-called Peace of Augsburg); but the arrangement was artificial and proved itself untenable as a permanent instrument of peace.
During the latter part of the sixteenth century two magnates of the empire, the Duke of Bavaria on the Catholic side and the Calvinist, Christian of Anhalt, on the Protestant, played the chief rôle, the Lutheran Markgrave of Saxony taking up a moderate position as mediator. Of the Reichstag of Augsburg it should be said that it had ignored the Calvinist section of the Protestant party altogether, only recognizing the Lutheran. In 1608 the Protestant Union, which embraced Lutherans and Calvinists alike, was founded under the leadership of Christian of Anhalt. It was most powerful in Southern Germany. This was countered immediately by the foundation under Maximilian, Duke of Bavaria, of a Catholic League. The friction, which was now becoming acute, went on increasing till the actual outbreak of the Thirty Years' War in 1618. The signal for the latter was given by the Bohemian revolution in the spring of that year.
The Thirty Years' War, as it is termed, which was really a series of wars, naturally falls into five distinct periods, each representing in many respects a separate war in itself. The first two years of the war (1618-20) is occupied with the Bohemian revolt against the attempt of the Emperor to force Catholicism upon the Bohemian people and with its immediate consequences. It was accentuated by the attempt of the Emperor Matthias to compel them to accept the Archduke Ferdinand as King. This attempt was countered through the election by the Bohemians of the Pfalzgraf, Friedrich V (the son-in-law of James I of England), who was called the Winter King from the fact that his reign lasted only during the winter months; for though the Protestant Union, led by Count Thurn, had won several victories in 1618 and even threatened Vienna, the Austrian power was saved by Tilly and the Catholic League which came to its rescue. Many of the Protestant States, moreover, were averse to the Palatine Friedrich's acceptance of the Bohemian crown. The Bohemian movement was ultimately crushed by a force sent from Spain, under the Spanish general Spinola. The final defeat took place at the battle of the White Hill, near Prague, November 8, 1620.
The second period of the war was concerned with the attempt of the Catholic Powers to deprive Friedrich of his Palatine dominions. Here Count Mansfeld, with his mercenary army of free-lances, aided by Christian of Brunswick and others on the side of Friedrich and the Protestants, defeated Tilly in 1622. But later on Tilly and the Imperialists by a series of victories conquered the Palatinate, which was bestowed upon Maximilian of Bavaria. Mansfeld, notwithstanding that he had some successes later in the year 1622, could not effectually redeem the situation, Brunswick's army being entirely routed by Tilly in the following year at the battle of Stadtlohn, which virtually ended this particular campaign.
The third period of the war, from 1624 to 1629, is characterized by the intervention of the Powers outside the immediate sphere of German or Imperial interests. France, under Richelieu, became concerned at the growing power of the Hapsburgs, while James I of England began to show anxiety at his son-in-law's adverse fortunes, though without achieving any successful intervention. The chief feature of this campaign was the entry into the field of Christian IV of Denmark with a powerful army to join Mansfeld and Christian of Brunswick in invading the Imperial and Austrian territories. But the savageries and excesses of Mansfeld's troops had disgusted and alienated all sides. It was at this time that Wallenstein, Duke of Friedland, was appointed general of the Imperial troops, and soon after succeeded in completely routing Mansfeld at the battle of Dessau Bridge in 1626. Four months later Tilly completely defeated Christian IV and his Danes at Lutter. Wallenstein, on his side, followed up his success, driving Mansfeld into Hungary. Mansfeld, in spite of some fugitive successes in the Austrian dominions in the course of his retreat, was compelled by Wallenstein to evacuate Hungary, shortly after which he died. The campaign ended with the Peace of Lubeck in 1629.
The action of the Emperor Ferdinand in attempting to enforce the restitution of Church lands in North Germany was the proximate cause of the next great campaign, which constitutes the fourth period of the Thirty Years' War (1630-36). The immediate occasion was, however, Wallenstein's seizure of certain towns in Mecklenburg, over which he claimed rights by Imperial grant two years before. This, which may be regarded as the greatest period of the Thirty Years' War, was characterized by the appearance on the scene of Gustavus Adolphus, the Swedish King. He was not in time, however, to prevent the sacking of Magdeburg by the troops of Tilly and Poppenheim. The former, nevertheless, was defeated by the Swedes at the important battle of Breitenfeld in 1631. The following year the Imperial army was again defeated on the Lach. Thereupon Gustavus occupied München, though he was subsequently compelled by Wallenstein to evacuate the city. The last great victory of Gustavus was at Lützen in 1632, at which battle the great leader met his death. Wallenstein, who was now in favour of a policy of peace and political reconstruction, was assassinated in 1634 with the connivance of the Emperor. On September 6th of the same year the Protestant army, under Bernhard of Saxe-Weimar, sustained an overwhelming defeat at Nördlingen, and the Peace of Prague the following year ended the campaign.
The fifth period, from 1636 to 1648, has, as its central interest, the active intervention of France in the Central European struggle. The Swedes, notwithstanding the death of their King, continued to have some notable successes, and even approached to within striking distance of Vienna. But Richelieu now became the chief arbiter of events. The French generals Condé and Turenne invaded Germany and the Netherlands. Victories were won by the new armies at Rocroi, Thionville, and at Nördlingen, but Vienna was not captured. The Imperial troops were, however, again defeated at Zumarshauen by Condé, who also repelled an attempted diversion in the shape of a Spanish invasion of France at the battle of Lens in the spring of 1648. The Thirty Years' War was finally ended in October of the same year at Münster, by the celebrated Treaty of Westphalia.
The above is a skeleton sketch in a few words of the chief features of that long and complicated series of diplomatic and military events known to history as the Thirty Years' War.[25]
