This work investigates the complex and often volatile relationship between the Prussian military establishment and the political governance of the German state from the rise of the Great Elector to the end of the Second World War. Gordon A. Craig, a distinguished historian of German affairs, utilizes extensive archival research and primary source documentation to trace how the army evolved from a tool of the monarchy into an autonomous political force. The text argues that the military's insistence on independence from civilian oversight created a structural imbalance that fundamentally shaped the trajectory of German political life and contributed to the collapse of democratic institutions.

Historians and political scientists frequently cite this work as a foundational text for understanding the structural causes of German militarism. Readers often note the academic density of the prose, which provides a rigorous examination of the institutional mechanisms that allowed the military to exert disproportionate influence over the state.
