Throughout history, humanity has borne witness to the political and moral challenges that arise when people place national identity above allegiance to geo-political states or international communities. This book discusses the concept of nations and nationalism from social, philosophical, geological, theological and anthropological perspectives. It examines the subject through conflicts past and present, including recent conflicts in the Balkans and the Middle East, rather than exclusively focusing on theory. Above all, this fascinating and comprehensive work clearly shows how feelings of nationalism are an inescapable part of being human.
