Through a detailed examination of the Protestant Reformation and colonial nationalism, Philpott reveals how ideas about legitimate political authority have profoundly altered the international system.

This book is a must-read for anyone interested in understanding the origins of modern statehood and the role of ideas in shaping global politics.
