A comprehensive reassessment of the relevance of Gramsci's theory and practice at the beginning of the twenty-first century. Whilst commentaries on Antonio Gramsci and arguments surrounding his political and intellectual legacy have proliferated, little attention has been hitherto directed to linking the connections and contentions between Political Theory and International Political Economy. This volume brings together leading authorities engaged in common debates to produce, for the first time, a major collection that clarifies, addresses, and lays bare the manifest connections and contentions within political and international theory surrounding the legacy of Antonio Gramsci. In Part I, scholars examine various approaches to Gramsci's thought, including his methodological principles, the specific conception of civil society he offers, his writings on war and cultural struggle, the spatial dimension of his thinking, and his philosophy of history. Part II focuses on very new developments in Gramsci scholarship concerning the questioning of contemporary world order. This includes reflections on his relevancy to issues of globalising capitalism, transformations in the state, revolutionary praxis, orientalism and empire, as well as European regionalism. This book was previously published as a special issue of the leading "Critical Review of International Social and Political Philosophy (CRISPP)".
