This volume investigates the evolution of the relationship between the American citizen and the state through the lens of military service and national defense obligations. Author Laura Kalman, a distinguished legal historian, utilizes a vast array of primary source documents to trace how the concept of the citizen-soldier has shifted from the colonial era to the modern day. The text argues that these changing expectations of service reflect broader transformations in American political identity, social responsibility, and the constitutional limits of federal power.

Scholars and historians frequently cite this work as a comprehensive reference for understanding the legal and social history of American military obligation. The text is noted for its academic rigor and its ability to synthesize complex legislative history into a coherent narrative for students and researchers alike.
