This book investigates the moral legitimacy of nationalism by examining the ethical merits and constraints of national self-determination and state-building. Margaret Moore, a scholar in political theory, synthesizes philosophical inquiry with empirical analysis of contemporary conflict zones. She constructs a framework to evaluate the rights of secession, the ethics of state-sponsored national privileging, and the appropriate accommodation of minority and multicultural groups within a sovereign state.

Experts recognize this work as a significant contribution to the normative study of nationalism and state policy. Readers frequently note the clarity with which the author navigates complex philosophical arguments while maintaining a focus on practical political application.
