How did the rapid expansion of telegraphic networks fundamentally reshape the political, social, and economic landscape of 19th-century Germany? Jean-Michel Johnston examines the integration of the telegraph into the German state, arguing that this technological infrastructure was not merely a tool for communication but a catalyst for national unification and bureaucratic modernization. Drawing on extensive archival research, the author analyzes the interplay between state policy, private enterprise, and the physical expansion of wires across the German landscape.
