Law is usually understood as an orderly, coherent system, but this volume shows that it is often better understood as an entangled web. Bringing together eminent contributors from law, political science, sociology, anthropology, history and political theory, it also suggests that entanglement has been characteristic of law for much of its history. The book shifts the focus to the ways in which actors create connections and distance between different legalities in domestic, transnational and international law. It examines a wide range of issue areas, from the relationship of state and indigenous orders to the regulation of global financial markets, from corporate social responsibility to struggles over human rights. The book uses these empirical insights to inform new theoretical approaches to law, and by placing the entanglements between norms from different origins at the centre of the study of law, it opens up new avenues for future legal research.
