Antonio Gramsci’s ‘Prison Notebooks’ have offered concepts, categories, and political solutions that have been applied in a variety of social and political contexts, from postwar Italy to the insurgencies of the Arab Spring. The contributors to ‘Gramsci in the World’ examine the diverse receptions and uses of Gramscian thought, highlighting its possibilities and limits for understanding and changing the world. Among other topics, they explore Gramsci’s importance to Caribbean anticolonial thinkers like Stuart Hall, his presence in decolonial indigenous movements in the Andes, and his relevance to understanding the Chinese left. The contributors consider why Gramsci has had relatively little impact in the United States while also showing how he was a major force in pushing Marxism beyond Europe — especially into the Arab world and other regions of the global South. Rather than taking one interpretive position on Gramsci, the contributors demonstrate the ongoing relevance of his ideas to revolutionary theory and praxis.
