Book excerpt: The eight chapters in this book explore more than 150 years of the development of several modern sports – baseball, basketball, cricket, football, handball, ice hockey and lacrosse – across the two Americas, Asia, Australia and Europe, some analysing a century of events since the mid-nineteenth century and some only a few years in the very present. Drawing on the methods of history, international relations, political science, and sociology, the contributing authors examine various theories of sporting globalization. The chapters take a balanced look at the concepts of the nation state and the connected world, which are the substantive core around which modern human society is ordered. They construct stories of entanglements and convergences, from within and without the nation state, in which the national and the non-national are not mutually exclusive. The key features of this collection are how cultural elements are introduced to sport, how changes are perceived, how sporting practices and institutions can be defined at geopolitical and other levels, how we might conceptualize the perimeter of judging the national–transnational or the local–translocal paradigms, and how we could complicate the understanding of sport/knowledge transfer by ascribing different degrees of importance to origin, process, purpose, outcome, personnel and network. This book is a multidisciplinary exploration into the development of modern sporting culture from global and transnational history perspectives. The chapters originally published as a special issue in Sport in Society.
