Although the first decade of the German Empire has long been a central topic of historical research, the question with which this essay is concerned—Bismarck's relationship to the pressure groups at this time—cannot be answered satisfactorily on the basis of the material known hitherto. This is due to the fact that until very recently historians have concentrated on the diplomatic-political occurrences. Bismarck's eastern policy, the Livadia affair, the ‘war-in-sight crisis’, the Berlin Congress, and the change from the Three Emperors' Alliance to the ‘Eternal’ Treaty with the Danube monarchy—these are the events always used to demonstrate Bismarck's ‘genius’ in the field of foreign policy. On the problem of the ‘Kulturkampf’ much less effort has been expended. Here Bismarck's outstanding political skill was not as apparent as it was in his judgement of international relations. Moreover, this question was bound up from the very beginning with a strong ideological bias which only slightly weakened after World War II for the first time. Even less attention has been paid to the problems of domestic and social policy and economic developments have been almost totally neglected. It is true that these items have recently obtained new historical relevance from the new socio-political point of view, but up to the present day they have not been clarified. The chief general contributions of this kind have been published by non-German historians (e.g. Rosenberg, Lambi, and Pflanze) in the United States or in Canada. These studies, however, give inadequate answers to specific questions, as do the detailed essays of Karl-Erich Born and Wolfgang Zorn with their systematizing way of reflexion. They do not deal with our formulation of the question: the relationship between economic development and political events in a comparatively short period. Nevertheless, the essays of Born and Zorn will serve as a starting-point for our own investigation. Born in particular realizes the urgent need for more detailed research in the social and economic sphere, and pleads for a ‘supplementary’ approach (Ergänzungsgeschichte). He states that
the history of the aristocracy during the industrial age has to be completed by studies dealing with the history of the trade unions; by dissertations on the history of industrial branches, commercial centres, and companies; and last but not least by works on the disintegration of the old bourgeoisie. Then we shall be able to extend the political history of the German Empire, which is largely clarified, to a comprehensive view of a German historical epoch by adding the social and economic history of the late nineteeth century.
