Does law drive social transformation, or does it merely reflect deeper social forces? This question has animated the law and social change subfield for over a century. At its core, the subfield examines how legal institutions, doctrines, and practices both shape and are shaped by social movements, economic pressures, and cultural shifts. Scholars in this tradition treat law not as a neutral instrument but as a contested terrain where competing visions of justice collide. The frameworks that have emerged over the past hundred years each offer a distinct answer to the question of how law and social change relate—and each has left a lasting imprint on the field.
The first systematic attempt to theorize law as a social phenomenon came from Sociological Jurisprudence (1910–1930). Led by Roscoe Pound, this framework argued that law should be understood as a tool for social engineering—a way to balance competing interests in a rapidly industrializing society. Pound rejected the formalist view that judges merely apply preexisting rules; instead, he insisted that law must adapt to social needs. Yet Sociological Jurisprudence remained largely reformist, assuming that legal elites could steer change from above.
Legal Realism (1920–1940) radicalized this insight. Drawing on the work of Karl Llewellyn, Jerome Frank, and others, the Realists argued that law is fundamentally indeterminate: judicial decisions are shaped by the judge's psychology, politics, and social context, not by neutral reasoning. Where Pound saw law as a manageable instrument, the Realists saw a system riddled with uncertainty. They shifted attention from what courts said to what courts actually did, laying the groundwork for empirical study of legal behavior. Legal Realism coexisted with Sociological Jurisprudence for a time, but its more skeptical stance eventually displaced Pound's optimistic engineering model. Both frameworks, however, shared a commitment to studying law in action rather than law on the books—a commitment that would echo through later movements.
The 1970s witnessed an explosion of new frameworks that challenged the assumptions of both earlier realism and mainstream liberal legalism. Critical Legal Studies (CLS, 1970–Present) emerged from a fusion of Legal Realism's indeterminacy thesis with neo-Marxist and poststructuralist thought. CLS scholars such as Duncan Kennedy and Roberto Unger argued that law is not merely indeterminate but deeply ideological: it naturalizes hierarchy and masks political choices as neutral rules. CLS rejected the reformist faith of Sociological Jurisprudence and the behavioral focus of Legal Realism, insisting that law must be understood as a site of political struggle. Its critique of liberal legalism—the idea that law can be a neutral arbiter—became a touchstone for later critical approaches.
Feminist Legal Theory (1970–Present) developed alongside CLS but with a distinct focus. Scholars like Catharine MacKinnon and Martha Fineman argued that law is not just ideological in general but specifically patriarchal: it reflects and reinforces male dominance. Feminist Legal Theory absorbed CLS's critique of neutrality while narrowing its lens to gender. It also diverged from CLS by insisting that law could be a tool for women's liberation, not merely an obstacle. This tension—between law as oppressive and law as emancipatory—remains a live debate within feminist scholarship.
Legal Mobilization Theory (1970–Present) took a different tack. Rather than focusing on legal doctrine or ideology, it asked how ordinary people and social movements actually use law to pursue change. Drawing on the work of Stuart Scheingold and later Michael McCann, this framework examined the conditions under which litigation, legal advocacy, and rights discourse empower or constrain collective action. Legal Mobilization Theory coexisted with CLS and Feminist Legal Theory, but it shifted the unit of analysis from the legal system itself to the grassroots actors who engage with it. It also introduced a more empirical orientation, studying real-world campaigns rather than abstract critique.
Legal Pluralism (1970–Present) challenged the state-centeredness of all previous frameworks. Building on earlier anthropological work, scholars like Sally Engle Merry and John Griffiths argued that law is not a monopoly of the state; multiple normative orders—customary law, religious law, community norms—coexist and interact within any social field. Legal Pluralism narrowed the focus of earlier frameworks by insisting that state law is only one form of regulation among many. It also complemented Legal Mobilization Theory by showing that social change often involves navigating multiple legal orders, not just the official court system.
Critical Race Theory (CRT, 1980–Present) emerged from the recognition that CLS and Feminist Legal Theory had not adequately addressed the centrality of race. Scholars like Derrick Bell, Kimberlé Crenshaw, and Richard Delgado argued that racism is not an aberration but a constitutive feature of American law. CRT drew on CLS's indeterminacy thesis but radicalized it by insisting that race—not just class or gender—is a fundamental axis of legal structure. It also introduced methodological innovations such as storytelling and intersectionality, which revealed how legal categories erase the experiences of people of color. CRT coexists with CLS and Feminist Legal Theory, but its insistence on the primacy of race has often put it in productive tension with those frameworks. Today, CRT remains one of the most influential and contested approaches in the subfield.
The 1990s brought a methodological turn that refocused attention on systematic data collection and everyday experience. Empirical Legal Studies (ELS, 1990–Present) revived the empirical impulse of Legal Realism but with more rigorous social science methods. Scholars in this tradition—often trained in economics, sociology, or political science—use quantitative and qualitative data to test whether legal reforms actually produce their intended effects. ELS narrowed the focus of earlier critical frameworks by setting aside normative critique in favor of measurable outcomes. It also coexists with CLS and CRT in a state of living disagreement: ELS scholars often accuse critical scholars of making untestable claims, while critical scholars argue that ELS ignores the ideological dimensions of law.
Legal Consciousness Research (1990–Present) took a different empirical path. Inspired by the work of Patricia Ewick and Susan Silbey, this framework examines how ordinary people understand, experience, and use law in their daily lives. Rather than studying high-profile litigation or doctrinal change, Legal Consciousness Research explores the subtle ways law shapes common sense—and how people resist or accommodate legal authority. This framework complements Legal Mobilization Theory by focusing on the cultural and cognitive dimensions of legal engagement, but it diverges by emphasizing the mundane rather than the strategic. Legal Consciousness Research also challenges the top-down assumptions of earlier frameworks like Sociological Jurisprudence, showing that law's power operates through everyday acceptance, not just elite engineering.
New Legal Realism (2000–Present) attempts to synthesize the empirical rigor of ELS with the critical insights of CLS, CRT, and Feminist Legal Theory. Scholars like Stewart Macaulay and Elizabeth Mertz argue that the original Legal Realists' call for empirical study was never fully realized, and that contemporary research must combine careful social science with attention to power, inequality, and context. New Legal Realism revives the spirit of early Legal Realism while absorbing the lessons of the critical and interpretive turns. It narrows the gap between ELS and critical frameworks by insisting that empirical work can be politically engaged without sacrificing methodological discipline. This framework remains a vibrant but contested project, as it tries to hold together commitments that have often pulled in opposite directions.
Today, the leading frameworks in law and social change—Critical Legal Studies, Feminist Legal Theory, Legal Mobilization Theory, Legal Pluralism, Critical Race Theory, Empirical Legal Studies, Legal Consciousness Research, and New Legal Realism—coexist as active research programs. They agree on several foundational points: law is not autonomous from society; legal change is shaped by power relations; and studying law requires attention to context, not just doctrine. They also share a rejection of the formalist view that law can be understood through internal logic alone.
Yet deep disagreements persist. The most significant fault line is between critical and empirical approaches. Critical scholars (CLS, CRT, Feminist Legal Theory) argue that law is fundamentally ideological and that empirical methods cannot capture its full political meaning. Empirical scholars (ELS, some strands of Legal Mobilization) counter that without systematic evidence, critical claims remain speculative. Legal Consciousness Research and New Legal Realism attempt to bridge this divide, but the tension remains unresolved. Another disagreement concerns the role of law in social change: some frameworks (Legal Mobilization Theory, parts of Feminist Legal Theory) see law as a potentially transformative resource, while others (CLS, CRT) emphasize law's tendency to co-opt and contain dissent. Legal Pluralism adds further complexity by questioning whether state law is even the most important site of change.
These debates are not signs of weakness; they reflect the subfield's vitality. The question that opened this overview—whether law drives or reflects social change—has no single answer. Instead, the frameworks offer different lenses for understanding the complex, often contradictory relationship between legal institutions and the societies they govern. For students entering the field, the challenge is not to pick a winner but to learn how each framework illuminates some aspects of law and social change while obscuring others.
