This book investigates the fundamental nature of nationalism and the persistent political and moral challenges that arise when national identity supersedes state allegiance. Steven Grosby, a scholar specializing in the study of nationalism and religion, utilizes a multidisciplinary framework to analyze how national identity functions across human history. He argues that nationalism is not merely a modern political construct but an inherent aspect of the human condition, rooted in social, theological, and anthropological foundations.

Experts and readers frequently cite this work as a highly accessible yet intellectually rigorous entry point into the study of nationalism. The text is noted for its ability to condense complex sociological and anthropological theories into a concise format suitable for students and general readers alike.
