This book examines the history of nation-building during the era of decolonization and the Cold War, and on the more recent post-Cold War and post-9/11 pursuit of nation-building in what have become known as ‘collapsed’ or ‘failed’ states. In the post-Cold War and post-9/11 era nation-building, or what is increasingly termed state-building, has taken on renewed salience, making it more important than ever to set the idea and practice of nation-building in historical perspective. Focusing on both historical and contemporary examples, the contributors explore a number of important themes that relate to ‘successful’ and ‘unsuccessful’ nation-building efforts from South Vietnam in the 1950s and 1960s to East Timor, Afghanistan and Iraq in the twenty-first century. From Nation-Building to State-Building was previously published as a special issue of Third World Quarterly and will be of interest to students and scholars of comparative politics and peace studies.
