It should be remembered as an apology for the stress now laid upon the sociological side of the history of the Thirty Years War, that that side has by historians been resolutely thrust into the background. The most detailed and painstaking narratives of the war are either bare records of military operations or, worse still, represent merely meticulous and valueless unravellings of the web of intrigue with which the pedants of the time deceived themselves into the belief that they were very Machiavels of subtlety and resource. While the Empire was bleeding to death, the chancelleries of half Europe were intent on the detaching from one side or the other of a venal general, or the patching up of some partial armistice that might afford breathing-time to organise further mischief. It does not matter much to any one whether Wallenstein was knave or fool, but it did matter and does matter that the war crippled for two hundred years the finances, the agriculture, and the enterprise of the German people, and dealt a blow to their patriotism from the like of which few nations could have recovered. Even the character of the civil administration was completely altered when the struggle ended. An army of capable bourgeois secretaries and councillors had for centuries served their princes and their fellow subjects well. It is wonderful that throughout the devastating wars waged by Wallenstein and Weimar, and even later on during the organised raids of Wrangel and Königsmark, the records were kept, the village business administered (where there was a village left), and even revenue collected with wellnigh as much regularity as in time of peace. These functionaries, who had worked so well, were at the end of the war gradually dispossessed of their influence, and their posts were taken by a swarm of young place-hunters of noble birth whom the peace had deprived of their proper employment, and whose pride was only equalled by their incapacity. But neither particulars nor generalisations bearing on such subjects are to be found in the pages of professional historians; they must be sought in the contemporary records of the people, of which the present work affords one of the few existing specimens, or else in the work of picturesque writers who, laying no claim to the title of scientific investigators, yet possess the power of selecting salient facts and deducing broad conclusions from them. Freitag's "Bilder aus der Deutschen Vergangenheit" indicates a wealth of material for sociological study which has as yet been but charily used; and recent German works dealing directly with the subject are more remarkable for elegance of production than for depth of research.
