For centuries, the dominant image of law in Western thought was that of a unified, hierarchical system emanating from a single sovereign source. This picture—often called legal centralism—held that law is the exclusive province of the state, uniform in its application and supreme over all other forms of social ordering. Yet from the earliest encounters with colonial societies, observers noted that people often lived by multiple, overlapping normative orders: customary rules, religious law, local practices, and the official law of the colonizer. The challenge of making sense of this coexistence is the engine that has driven the subfield of legal pluralism. Over the past century, scholars have moved from simply documenting the fact of legal diversity to building sophisticated frameworks that ask how different legal orders interact, conflict, and shape one another.
The roots of legal pluralism lie in two parallel traditions that began to question state-centered definitions of law. In Europe, the sociological jurist Eugen Ehrlich argued in his 1913 work Fundamental Principles of the Sociology of Law that the "living law" of social associations—families, villages, merchant guilds—was more consequential than the formal law of the state. Ehrlich insisted that law was not a top-down command but an emergent property of social life. Meanwhile, early legal anthropologists such as Bronisław Malinowski and Max Gluckman studied dispute resolution in stateless societies, showing that order could be maintained through reciprocity, kinship obligations, and public pressure without a centralized legal apparatus. These scholars did not yet use the term "legal pluralism," but they laid the groundwork by demonstrating that law could exist outside the state. Their work remained largely descriptive, focused on documenting alternative systems rather than theorizing the relationships between them.
The first self-conscious framework for legal pluralism emerged in the 1970s, driven by anthropologists and sociologists who sought to formalize the insights of their predecessors. Classical Legal Pluralism defined itself against legal centralism by asserting that multiple legal orders can coexist within the same social field. A landmark statement came from John Griffiths in his 1986 article "What is Legal Pluralism?," which distinguished between "weak" legal pluralism—where the state recognizes multiple legal systems (as in colonial indirect rule)—and "strong" legal pluralism, where legal orders are fundamentally heterogeneous and not derived from a single source. For Griffiths, strong pluralism was the normal condition of all societies, not just colonial ones. This framework was a formalization of earlier anthropological work: it took the empirical observation of legal diversity and turned it into a general theoretical claim about the nature of law. Yet Classical Legal Pluralism tended to treat legal orders as bounded, self-contained systems—a view that later scholars would find too static.
By the 1980s, a new generation of scholars began to argue that legal orders are not separate spheres but are deeply interwoven and mutually constitutive. New Legal Pluralism shifted the focus from the coexistence of distinct systems to the processes of interaction, negotiation, and hybridity. Sally Falk Moore’s concept of the "semi-autonomous social field" was central to this shift. Drawing on fieldwork among the Chagga of Tanzania, Moore showed that social fields—such as a factory, a village, or a trade union—generate their own internal rules while also being subject to state law and other external pressures. The key move was methodological: instead of mapping separate legal orders, Moore analyzed how people navigate multiple normative frameworks in their everyday lives. Boaventura de Sousa Santos later coined the term "interlegality" to describe the fluid, porous quality of legal life, where different legal orders interpenetrate and mix. New Legal Pluralism thus broadened the scope of inquiry from colonial and postcolonial settings to any complex society, including urban industrial ones. It replaced the image of separate legal systems with one of overlapping, dynamic legal landscapes.
Feminist scholars entering the field in the 1990s pointed out that earlier legal pluralism had been largely gender-blind. Women’s experiences of legal pluralism, they argued, were often distinct from men’s, particularly in contexts where customary or religious law governed family matters, inheritance, and personal status. Feminist Legal Pluralism did not reject the insights of New Legal Pluralism but narrowed the analytical lens to ask how legal pluralism operates differently for women and men. It highlighted the ways in which multiple legal orders can create both opportunities and constraints for women: for example, a woman might appeal to state law to escape a customary marriage, only to find that state courts themselves are patriarchal. This framework also brought attention to the informal, non-state arenas where women’s legal lives are shaped—households, community tribunals, religious councils—and insisted that these sites be taken seriously as legal spaces. Feminist Legal Pluralism coexists with other contemporary frameworks, offering a critical perspective that insists on the gendered dimensions of legal ordering.
Developing alongside the feminist critique, Postcolonial Legal Pluralism emerged from a sustained engagement with the history of colonialism and its aftermath. Scholars such as Mahmood Mamdani argued that colonial powers did not simply impose their own law but actively constructed and codified "customary" law as a tool of governance. This manufactured legal pluralism—where the colonizer recognized a distorted version of indigenous law—created enduring hierarchies and ethnic divisions that persist in postcolonial states. Postcolonial Legal Pluralism thus transformed the understanding of legal pluralism itself: it is not a neutral fact of social life but a product of power, often imposed from above. This framework shares with Feminist Legal Pluralism a critical orientation toward earlier, more descriptive approaches, but its focus is on the colonial genealogy of legal orders and the ways in which legal pluralism can entrench inequality. It remains in living disagreement with frameworks that treat legal pluralism as inherently emancipatory or democratic.
The most recent major framework, Global Legal Pluralism, extends the analysis of legal pluralism beyond the nation-state to the transnational arena. As economic globalization, international human rights regimes, and digital networks have proliferated, scholars have asked whether the same pluralist dynamics that operate within states also operate at the global level. Paul Schiff Berman, a leading voice, argues that global legal pluralism is a response to the fragmentation of authority in a world where no single sovereign can claim supremacy. The framework examines phenomena such as lex mercatoria (the customary law of international commerce), the rulings of international tribunals, and the normative orders of religious diasporas that span borders. Global Legal Pluralism addresses a gap left by earlier frameworks: how to theorize legal ordering when the state is no longer the primary container of law. It has become the leading framework in part because it speaks directly to contemporary concerns about governance beyond the state, but it also builds on the insights of New Legal Pluralism about interlegality and hybridity.
Today, Feminist, Postcolonial, and Global Legal Pluralism are all active traditions, each with its own emphasis. They agree on several foundational points: that legal centralism is empirically false, that multiple normative orders coexist in every society, and that power relations shape how these orders interact. Yet they disagree on what should be the primary unit of analysis. Feminist scholars insist on the centrality of gender; postcolonial scholars foreground the colonial past and its enduring structures; global pluralists focus on transnational flows and institutions. A key tension is whether legal pluralism should be understood primarily as a descriptive tool or as a normative project. Some argue that recognizing legal pluralism can foster tolerance and accommodate difference; others warn that it can legitimize oppressive practices, such as patriarchal customary law or corporate self-regulation. The field remains animated by these disagreements, and the most productive work today often combines insights from multiple frameworks—for example, analyzing how a transnational human rights norm interacts with local gender orders in a postcolonial setting. Legal pluralism has thus evolved from a simple observation of diversity into a rich, contested set of tools for understanding law in a complex world.
