Historians have often viewed the history of the German empire with Berlin firmly in the centre of the lens, thus privileging the nation-state to the neglect of both the local and the transnational. Zooming out to include transnational processes such as migration and to globalise German history enables us to complicate the dominant narratives of the German nation-state. The movements of Germans overseas—whether as migrants, missionaries, or merchants—helped to forge a global presence for the German empire, but also entailed complex negotiations both among Germans and between Germans and their various “others,” thus revealing the ways in which German nationalist and colonial discourses and practices adapted to local conditions. While the German empire sought to establish itself as a colonial power abroad only in the late nineteenth century, Prussia-Germany was already a colonial power at home, in its eastern provinces. Zooming back in from the global to the local, and refocusing from Berlin to the borderlands, further complicates our understandings of the German empire, by revealing the ways in which local conditions in the eastern borderlands, themselves influenced by transnational phenomena such as international migration, informed the development of German nationalism there. Most notably, the demographics of the Prussian eastern provinces—and the movements of Jews, Germans, Poles, and Ruthenians/Ukrainians in and out of the region—required German nationalists to integrate greater flexibility into their discourse.
