Situated Marxism analyzes theoretical practices in postwar Eastern Europe and the Soviet Union on their own terms and within their institutional, social, and historical contexts. Challenging enduring narratives of dogma and decline, twelve case studies from across the region trace how Marxist thought engaged with science, ecology, global futures, and Western philosophy, and how these engagements shaped new understandings of orthodoxy. The volume reveals a rich intellectual tradition with continuing relevance to today’s debates on knowledge, crisis, and social justice.
