For much of the nineteenth and early twentieth centuries, legal history belonged to the law faculties. Its practitioners traced the lineage of doctrines: how the action of trespass gave rise to negligence, how Roman categories survived in the German Pandects. The audience was lawyers, and the purpose was largely to explain how present rules had come to be.

Savigny's historical school in Germany and the English tradition associated with Maitland differed in method and temperament. Yet both treated law as a relatively autonomous body of thought. Its history was what Robert Gordon would later call internal legal history, the story of legal ideas reasoning their way forward through cases, treatises, and codes.

Over the second half of the twentieth century, that autonomy dissolved. Three movements asked new questions of the same material: law and society scholarship, critical legal history, and social historians' use of court records. Comparing them reveals not a single revolution but a series of sharp disagreements about what law actually is, and about where historians should look to find it.

The decisive American turn came from J. Willard Hurst at the University of Wisconsin. Building on Roscoe Pound's 1910 distinction between 'law in books' and 'law in action,' Hurst moved attention away from appellate opinions. He looked instead at statutes, administrative practice, land policy, and the ordinary transactions through which people used law. Timber rights and lumber contracts mattered more to him than the elegant reasoning of high courts. His students would make the 'Wisconsin school' synonymous with this reorientation.

His Law and the Conditions of Freedom in the Nineteenth-Century United States (1956) argued that American law aimed at a 'release of energy,' channelling public authority toward private enterprise and economic growth. The governing question was no longer whether a doctrine was internally coherent. It was what work the doctrine performed in a developing market society. Legal history became a branch of social and economic history rather than a preface to legal reasoning.

Lawrence Friedman's A History of American Law (1973) extended the programme, treating law as a product of social demands and pressures. Here the approach's strength and its limitation coincide. By insisting that law responds to society, the law and society school opened enormous new terrain. Yet it drifted toward functionalism, a model in which law simply mirrors interests and possesses little causal force or internal logic of its own.

Critics also noticed what Hurst's consensual portrait left out. A nation united around growth said little about who paid when energy was released. It had little room for workers injured under new liability rules, Native nations dispossessed through land law, or enslaved people classified as property. These absences followed from the framework's assumption of shared purpose. They opened the door for a more adversarial reading of the same sources.

Takeaway

Asking what law does rather than what law says transforms the archive, the method, and the conclusions. But a purely functional answer risks making law disappear into society altogether.

Critical legal history emerged in the 1970s and 1980s alongside the Critical Legal Studies movement, and it began by rejecting consensus. Morton Horwitz's The Transformation of American Law, 1780–1860 (1977) argued that antebellum judges reshaped property, contract, and tort doctrine to subsidise commercial and industrial interests. Growth was not a shared national project. Its costs were shifted onto farmers, workers, and the weaker parties to bargains.

Robert Gordon's 1984 essay 'Critical Legal Histories' pressed further. He challenged Marxist instrumentalism as well as liberal functionalism. Law, Gordon argued, does not merely reflect social relations; it helps constitute them. Categories like free contract, private property, and the public–private divide shape how people understand what is possible. Their power lies in making contingent arrangements appear natural and necessary, so that hierarchy comes to look like common sense.

British social historians reached related conclusions by different routes. Douglas Hay's essay in Albion's Fatal Tree (1975) argued that eighteenth-century criminal law sustained gentry authority through the theatre of majesty, justice, and mercy, with discretionary pardons binding the poor to their superiors. Yet E. P. Thompson, in Whigs and Hunters the same year, ended by calling the rule of law 'an unqualified human good,' insisting that legal forms constrained rulers too.

That tension defines the tradition's achievement and its difficulty. Critical historians showed that legal neutrality was itself a historical artefact worth explaining. But claims about ideology and naturalisation are hard to demonstrate empirically. John Langbein's rebuttal, 'Albion's Fatal Flaws' (1983), pointed out that most prosecutors were ordinary victims rather than elites. An emphasis on indeterminacy also made it difficult to explain why one outcome prevailed over another. How far law serves power, and how far it restrains it, remained unresolved.

Takeaway

Law's most durable effects may lie less in what it commands than in what it makes seem normal. Showing that something is constructed, however, is not the same as showing who built it or why.

A third transformation came largely from outside legal history. Social and cultural historians discovered that court records were among the richest surviving traces of ordinary lives. Emmanuel Le Roy Ladurie's Montaillou (1975) reconstructed a Pyrenean village from the inquisitorial register of Jacques Fournier. Carlo Ginzburg's The Cheese and the Worms (1976) recovered the cosmology of Menocchio, a sixteenth-century miller, from the transcripts of his heresy trials.

In this work, law was less the object of study than the means of access. Depositions, petitions, and interrogations preserved speech that left no other record. Yet the method raised an obvious problem. These documents were produced by power, often under threat. Ginzburg himself acknowledged that the inquisitor shaped what could be said. He also recognised that historians reading such texts stood uncomfortably close to the interrogator's position.

Natalie Zemon Davis's Fiction in the Archives (1987) turned the problem into a subject. Studying sixteenth-century French pardon tales, she treated supplicants' narratives as crafted stories, shaped by legal requirements, literary conventions, and the help of notaries. The 'fiction' was not falsehood but form. Legal procedure did not merely filter experience. It structured how people told their own lives, and therefore what historians could know about them.

This insight quietly reconnected the archive to doctrine. Later scholars read records as evidence of how people used and argued about legal rules. Hendrik Hartog examined the contested status of pigs on New York's streets. Laura Edwards studied localised law in the post-revolutionary American South. In such work, formal categories mattered again, now as things people inhabited. The archive was neither a transparent window nor a mere instrument of rule. It was a site where legal form and social life met.

Takeaway

Every legal record is both evidence of a life and evidence of the procedure that captured it. Reading one without the other produces either naive social history or bloodless legal history.

Each tradition answered the doctrinal approach differently. Law and society scholarship showed that law's meaning lay in its effects. Critical legal history exposed how legal categories legitimated inequality. Social historians turned the courtroom record into a source for lives otherwise lost.

Each also carried characteristic blind spots. Functionalism tended to dissolve law into society. Ideology critique struggled with evidence. Archival readings sometimes forgot the legal machinery that produced their sources.

The most compelling recent work combines these approaches. It treats doctrine neither as autonomous reasoning nor as mere reflection, but as one of the ways societies argue with themselves. The internal history the field once abandoned has returned, now embedded in the contexts it previously ignored.
