Power rarely works by force alone: it also rules by winning hearts and minds. States, classes, and social groups all seek political dominance by exerting political, ideological, or cultural leadership over others. This idea - hegemony - is a subtle, complex one, which is too often applied crudely. In this succinct introduction, political theorist James Martin skilfully examines these nuances and shines a new light on hegemony. He introduces its component ideas and critically surveys the most influential thinking about hegemony, from Gramsci's theory of hegemony as a revolutionary strategy and Marxist theories of the state, politics, and culture to the Post-Marxist project of radical democracy. He then considers the concept's critical role in analysing international politics and global political economy, and evaluates the criticism that hegemony is too state-centric to truly capture the dynamics of contemporary struggles for emancipation. This lucid and accessible guide to hegemony will be essential reading for all students of radical politics and social and political theory.
