While rivalry is embedded in any sporting event or performance, soccer, the world’s most popular mass spectator sport, has been an emblem of such rivalries since its inception as an organized sport. Some of these rivalries grow to become long-term and perennial by their nature, extent, impact and legacy, from the local to the global level. They represent identities based on widely diverse affiliations of human life—locality, region, nation, continent, community, class, culture, religion, ethnicity, and so on. Yet, at times, such rivalries transcend barriers of space and time, where soccer-clubs, -nations, -personalities, -organizations, -styles and -fans float and compete with intriguing identities. The present volume brings into focus some of the most fascinating and enduring rivalries in the world of soccer. It attempts to encapsulate, analyse and reconstruct those rivalries—between nations, between clubs, between personalities, between styles of play, between fandoms, and between organizations—in a historical perspective in relation to diverse identities, competing ideologies, contestations of power, psychologies of attachment, bonds of loyalty, notions of enmity, articulations of violence, and affinities of fan culture—some of the core manifestations of sporting rivalry. The chapters in this book were originally published as a special issue of Soccer & Society.
