The Weird Medieval Law That Once Punished Animals for Crimes
In 1386, a court in Falaise, Normandy, sentenced a pig to death by hanging. The pig had been dressed in a waistcoat and gloves for the occasion, and the town reportedly paid its executioner for the job, according to municipal accounts reproduced by historian E.P. Evans.
This wasn’t an isolated absurdity. Medieval animal trials occurred across parts of Europe for several centuries, involving formal courts, appointed lawyers, and documented legal verdicts against animals accused of crimes.
The story of how this practice worked, and why it existed, reveals more about medieval law than it does about the animals themselves.
The Pig That Stood Trial in Falaise, Normandy
The Falaise case remains one of the most frequently cited examples in the historical record of animal prosecution. According to E.P. Evans‘s 1906 study, “The Criminal Prosecution and Capital Punishment of Animals,” a sow was formally tried and convicted after mauling a child.
Evans compiled his research from surviving French municipal and court records, along with earlier chronicles documenting similar cases across multiple centuries.
A Sentence Carried Out in Public
The sow’s punishment reportedly mirrored the format used for human executions of the period, including public display and formal ritual. According to local Falaise historical accounts, the event was later commemorated in a painted fresco inside the town’s Church of the Trinity, though the fresco’s exact origin and dating remain.
A similar case occurred in Savigny in 1457, when a sow was tried and executed for a child’s death, while her six piglets were acquitted due to insufficient evidence connecting them to the attack, according to Evans’s documentation.
Two Distinct Categories of Medieval Animal Trials
Medieval animal trials generally fell into two separate legal categories, each following different procedures and serving different purposes, according to legal historian Paul Schiff Berman in his 1994 Columbia Law Review analysis of the practice.
Secular Courts Versus Ecclesiastical Courts
Secular courts handled individual animals accused of direct harm to people, typically domestic animals like pigs, cows, or horses involved in injury or death cases. These trials followed criminal procedure closely, sometimes resulting in execution.
Ecclesiastical courts, operating under canon law, instead handled cases involving pest species like rats, locusts, or weevils, threatening crops or property on a larger scale. These cases typically ended not in execution, but in formal excommunication or a religious curse pronounced against the offending species, Berman explains.
When a Lawyer Defended a Colony of Rats
Perhaps the most famous ecclesiastical case involved rats accused of destroying a barley crop near Autun, France, sometime in the early 16th century.
Bartholomew Chassenée’s Delay Tactics
According to accounts compiled by Evans, a young lawyer named Bartholomew Chassenée was appointed to defend the accused rats. Rather than arguing innocence directly, Chassenée reportedly argued the rats couldn’t safely travel to court, citing genuine danger from cats along the route.
Chassenée successfully petitioned for safe conduct guarantees and repeated delays, according to legal historian Peter Dinzelbacher, writing in the Journal of Interdisciplinary History in 2002. The case eventually lapsed without a clear resolution, though Chassenée’s legal reputation grew significantly afterward, later leading to a prominent career in French law.
Why Medieval Society Prosecuted Animals At All
The practice can seem baffling by modern legal standards, but it reflected a specific medieval understanding of law, order, and divine justice.
Katie Sykes, writing in the Animal Law Review in 2011, argues these trials weren’t primarily about assigning human-level moral responsibility to animals. Instead, they functioned as formal community rituals restoring a sense of legal and religious order after a disruptive event, according to Katie Sykes.
Ecclesiastical trials against pests carried particular religious significance. Communities facing crop failure often interpreted the damage as a form of divine punishment, making a formal legal or religious response feel necessary, Sykes notes, regardless of whether the underlying species could realistically appear in court.
How Reliable Is the Historical Record?
Much of what’s known today about medieval animal trials traces back to a single influential 1906 source, a detail that matters significantly for evaluating how confidently modern readers should treat individual case details.
E.P. Evans and the Limits of Nineteenth-Century Scholarship
Evans compiled dozens of alleged cases from earlier chronicles, court fragments, and secondary historical accounts spanning several centuries and multiple countries. His book remains the foundational source most later writers on the topic still cite directly.
Peter Dinzelbacher’s 2002 review notes that some of Evans’s sources were themselves several centuries removed from the events they described, raising legitimate questions about how precisely certain details, including exact dates, sentencing language, and courtroom procedure, were preserved. This doesn’t mean the broader practice didn’t occur, Dinzelbacher clarifies, but it does mean individual case details deserve some scholarly caution.
What Legal Scholars Make of Animal Trials Today
Modern legal historians generally treat medieval animal trials as genuine, if unusual, examples of pre-modern legal procedure rather than as folklore or exaggeration.
Paul Schiff Berman’s analysis frames the trials as evidence of how deeply medieval communities embedded law within religious and moral frameworks, rather than treating legal process as a purely secular mechanism separate from spiritual belief.
Katie Sykes has also argued the trials offer an unexpectedly useful historical lens for modern animal law discussions, illustrating how legal systems have long grappled with questions about animal agency, culpability, and the proper limits of formal justice.
A Practice That Quietly Disappeared
Animal trials gradually declined as European legal systems moved toward Enlightenment-era distinctions between human moral agency and animal behavior, a shift Berman connects to broader changes in legal philosophy during the 17th and 18th centuries.
No single law explicitly banned the practice across Europe. It simply stopped appearing in court records as legal thinking evolved, leaving behind a documented but genuinely strange chapter of pre-modern legal history, preserved largely through Evans’s original research and the scholars who later reexamined it.
