Book excerpt: Why do nations come into conflict? What factors lead to the horrors of ethnic cleansing? This timely book offers clear-eyed answers to these questions by exploring how national identity is shaped by place, focusing especially on Serbia, Hungary, and Romania. Moving beyond studies of nationalism that consider only the economic and geostrategic value of territory, George W. White shows that the very core of national identity is intimately bound to specific places. Indeed, nations define themselves in terms of spaces that have historical, linguistic, and religious meaning, as Serbs have clearly demonstrated in Kosovo. These territories are concrete expressions of a nationAIs identity, both past and present. With his detailed analysis of the places that define national identity in Southeastern Europe, White convincingly shows why territorial disputes so often escalate into war.
