With increasing globalization, the meaning and role of the nation-state are in flux. At the same time, state theory, which might help to explain such a trend, has fallen victim to the general decline of radical movements, particularly the crisis in Marxism. This volume seeks to enrich and complicate current political debates by bringing state theory back to the fore and assessing its relevance to the social phenomena and thought of our day. Throughout, it becomes clear that, whether confronting the challenges of postmodern and neo-institutionalist theory or the crisis of the welfare state and globalization, state theory still has great analytical and strategic value.
