Just imagine: a judge opens a trial, a prosecutor reads out the indictment, a defence lawyer raises an objection – and sitting in the dock is a rat. What sounds like a bad joke today was a matter of the utmost seriousness in the Middle Ages and early modern period: animals such as rats, pigs or even locusts were actually put on trial, with charges, a defence lawyer and a verdict in accordance with formal legal procedures.

Key findings
- Trials of animals were legal practices taken seriously, which followed strict formal rules – involving charges, witnesses, defence counsel and a verdict.
- Most of the animal trials recorded in historical sources took place between the 13th and 18th centuries, primarily in France, western Germany, northern Italy and Switzerland.
- Rats and other pests were usually tried before ecclesiastical courts, whilst pigs and other farm animals were tried before secular courts.
- A particularly well-known example is the Autun rat trial of 1522, in which the lawyer Barthélemy de Chasseneuz acted as defence counsel for the rats.
- These trials served primarily symbolic, social and religious functions – they did not recognise our modern-day concept of individual guilt.
Introduction: What were medieval animal trials?
In the Middle Ages and early modern period, animals were indeed put on trial, with charges, defence counsel and verdicts in accordance with formal legal rules. Historians confirm that such animal trials took place, although the exact number and reliability of individual recorded cases are a matter of debate amongst researchers. Most of these trials took place between the 13th and 17th centuries, with isolated instances continuing into the 18th century.
A distinction was made between two types of proceedings: secular courts tried individual domestic and farm animals such as pigs, a dog or a bull – usually following an attack on a human. Ecclesiastical courts, on the other hand, dealt with entire populations of pests: rats, mice, locusts, insects or grubs.
For those with an interest in history, students of legal history and cultural studies, this topic illustrates how closely law, religion and the management of natural hazards were intertwined in the Middle Ages – and why animal trials still reveal something about guilt, punishment and the changing relationship between humans and animals to this day. The focus here is on the history of these trials, famous cases such as Autun in 1522 and Falaise in 1386, the differences between secular and ecclesiastical courts, and their symbolic significance. The popular image of a pig on the gallows or a rat on trial is partly based on later literary embellishment, yet genuine trial documents and even receipts for payments still exist today – archived in French municipal archives as sources for one of the most unusual chapters in European legal history.
Rat trials before ecclesiastical courts: The Autun case


The most famous case of a rat trial takes us to Burgundy. In 1522, rats were summoned to appear before an ecclesiastical court in the diocese of Autun – a rural region with significant barley and wheat cultivation. Rat plagues were widespread in Europe at the time, and recurring crop failures drove farmers to despair. When rats once again ravaged the grain fields, the community turned to the ecclesiastical court: the bishop’s representative demanded that the rats be excommunicated and placed under an ecclesiastical ban.
The trial followed a surprisingly formal procedure:
- An ecclesiastical prosecutor brought a collective charge against the rats for theft and the destruction of the barley harvest.
- The statement of claim was read out in public, and several formal summonses were issued.
- As the rats did not appear, a defence counsel was appointed for them: the distinguished jurist Barthélemy de Chasseneuz (c. 1480–1541), who later became known as a commentator on Burgundian customary law.
As the lawyer for his unusual clients, Chasseneuz argued with remarkable legal acumen. Three objections in particular have been historically recorded:
- The first summons was invalid, as it was addressed only in general terms to ‘some rats’, without naming all the animals concerned individually.
- The rats could not safely make their way to court, as cats were lurking everywhere – his clients were therefore entitled to safe passage.
- His clients were scattered across a wide area, so that for many animals the journey would amount to an arduous trek and more time would have to be allowed.
With this defence strategy, Chasseneuz effectively managed to delay proceedings and ultimately secured a de facto dismissal of the case. For the community, the real purpose was not, in any case, to secure an enforceable penalty: the mere formal conduct of the trial was already interpreted as a symbolic banishment of the plague and a restoration of the divine order. Today’s historians and cultural scholars see this as a chapter in legal history that illustrates how familiar court rituals were employed to cope with natural disasters for which there was otherwise no explanation.
Between symbol and punishment: pigs, rats and other animals on trial

The Autun case was not an isolated incident. Recorded animal trials covered a wide range of animals – from pigs to cockchafers, from dogs to locusts. The following overview places the rat trials within the broader context of medieval criminal justice.
| Year | Place | Animal | Charge | Outcome |
|---|---|---|---|---|
| 1386 | Falaise, Normandy | Pig | Fatal injury to a small child | Execution by hanging, dressed in human clothing |
| 1457 | Savigny | Sow | Death of a child | Sentencing of the animal |
| 1499 | Sèves | Pig | Homicide | Execution |
| 1522 | Autun | Rats | Destruction of the grain harvest | Collective proceedings, effectively discontinued |
In the case of Falaise in 1386, an original receipt from the executioner in charge has even survived, documenting the execution of a sow aged around three years. According to tradition, the animal was led publicly to the gallows dressed in human clothing – a waistcoat, gloves and trousers. A mural in the Church of the Holy Trinity in Falaise later depicted the scene, but was lost in the 19th century when the church walls were whitewashed.
Secular trials primarily dealt with cases involving the killing of individual animals and frequently resulted in their execution. In these proceedings, animals were formally treated in a similar manner to human defendants: with arrest, sometimes remand in custody, the examination of witnesses and a written judgement. At the same time, animals were usually classified in legal terms as objects or as property that had caused damage – a contradiction that makes the legal practice of the time particularly remarkable even today.
Ecclesiastical trials against pests such as rats, mice or locusts followed an entirely different logic. The ‘punishments’ imposed were purely symbolic in nature: excommunication, anathema, curses or a liturgically accompanied ‘expulsion’ from certain fields, for example through prayers, processions or holy water – a punishment without any physical enforcement. In these proceedings, too, the animals were sometimes assigned a court-appointed defence lawyer, and lawyers argued formally for or against their clients, just as if they were human defendants.
Trials involving animals thus served primarily to symbolically resolve crises: the reinterpretation of uncontrollable natural phenomena as a regulated, ritualised procedure simultaneously strengthened the authority of both the Church and the secular courts. Ecclesiastical trials were not aimed at punishing an individual perpetrator, but at symbolic purification and the restoration of order – this had nothing to do with modern concepts of animal welfare.
Legal culture and the world of faith: why animals were put on trial in the first place
Why did it seem plausible to an entire society to put a rat on trial? The answer lies in the medieval worldview. Animal trials reflected social fears and the desire for order: any disruption – crop failure, plague, a fatal animal attack – was regarded as a possible indication of a disrupted divine order, which had to be symbolically restored. Animals were conceived as being embedded within a cosmic order in which humans, animals and nature were closely interconnected, even though animals themselves were not usually regarded as independent legal entities.
Animal trials thus also reflect the legal and worldview of the time: they stood at the intersection of Roman law, scholastic theology and local customary law. Scholastically trained jurists engaged in serious debate as to whether and how non-human actors might and should be included in symbolic penal rituals. The social function was clearly discernible: the proceedings served as a means of symbolic conflict resolution – a kind of judicial theatre that channelled collective anxiety and assigned a form of responsibility without having to name a human scapegoat.
Academic discourse: between historical reality and later embellishment
In contemporary research, there is considerable controversy over how reliable individual recorded animal trials are. The Austrian medievalist Peter Dinzelbacher has studied the subject in depth and classified animal trials as a real, serious legal practice of the Middle Ages and the early modern period.
Other researchers, however, call for greater critical analysis of the sources. The Göttingen-based legal historian Eva Schumann, for example, points out that no medieval legal sources have survived from the German-speaking world that unequivocally document formal criminal proceedings against animals, followed by a verdict and public execution. Even the trial of a pig burnt near Paris in 1266 or 1268 – often cited as the supposedly oldest case – has, upon closer examination of the sources, likely turned out to be a misunderstanding of the original account.
This debate demonstrates one thing above all: popular collections of animal trials, such as those that have been in circulation since the early 20th century, conflate well-documented, archival evidence – such as Falaise in 1386, with its preserved receipt of payment, or Autun in 1522, with its surviving court records – with stories that are less well-established or have been embellished over time. For those with an interest in history, it is therefore worth taking a closer look at each individual case, rather than dismissing animal trials wholesale as a consistently reliable, documented mass phenomenon or, conversely, as mere legend.
From the Gallows to the Animal Welfare Debate: A Changing Perspective on Animals
The treatment of animals in court has since undergone a fundamental transformation. Since at least the 18th century, the criminal justice system has increasingly focused on humans capable of criminal responsibility – under the current understanding of the law, animals cannot act ‘culpably’ in the criminal law sense. Nowadays, they are instead the focus of animal welfare law.
Philosophical debates, such as those surrounding the theories of the philosopher Peter Singer, as well as discussions about possible fundamental rights for great apes, whales or elephants, reveal a fundamentally new perspective on the role of animals in our society. Current research also demonstrates cultural learning in primates and a pronounced capacity for pain and emotion in many mammals.
The contrast with medieval practice is thus clear: back then, animals were regarded primarily as potential sources of misfortune, the punishment of which served to symbolically purify the community. Today, the focus is instead on the animal’s own capacity to suffer and on humanity’s responsibility towards it. The history of animal trials – from the rat in the dock to the pig on the gallows – vividly illustrates just how much our understanding of guilt, justice and our relationship with animals has changed since then. After all, the law is always a product of its time.
Animal Trials in Culture and Memory
The story of Chasseneuz and his unusual clients has also left its mark beyond specialist literature. The 1993 British feature film *The Advocate* (released in the United Kingdom under the title *The Hour of the Pig*) draws on Chasseneuz’s historical cases: In it, lead actor Colin Firth plays a lawyer in late medieval France who, amongst other things, defends a pig in court.
Medieval court scenes and historical trial documents also occasionally feature as exhibits in museums and exhibitions, serving as a reminder of this unusual chapter in legal history. For anyone interested in everyday life in the Middle Ages beyond the realm of knights and crafts, animal trials provide a vivid example of how closely everyday life, faith and the law were intertwined at that time.
Frequently Asked Questions
Did animal trials really take place, or are they just legends?
Contemporary written sources exist for several cases, such as Falaise in 1386, Autun around 1522, and the insect trial in Saint-Julien in 1587. Some particularly spectacular stories were embellished in later literature, and not every case cited in popular collections can be fully substantiated. The core of the story, however, is historically verified: animals were indeed brought to trial with charges, witnesses and a verdict – albeit less frequently and in a more varied manner than popular imagination sometimes suggests.
Why were pigs and rats accused so frequently?
In the Middle Ages, pigs roamed freely through villages and their surrounding areas in many places, occasionally injuring or killing children, which sparked public outrage and demanded that someone be held responsible. Rats, on the other hand, were regarded as typical grain pests and were brought to trial primarily in connection with famines. Depending on whether a secular or ecclesiastical court had jurisdiction, the animals faced either actual execution or a purely symbolic excommunication.
How could courts possibly enforce punishments against rats or insects?
Ecclesiastical punishments such as banishment or excommunication were purely symbolic in nature. There was no physical enforcement, as in the case of a pig led to the gallows. Their effectiveness lay solely in the faith of the congregation: people hoped for divine intervention and a reduction in the plague as a result of the ritual being performed.
Were the owners also punished for the actions of their animals?
In many cases, the owner was also held liable, for example through fines, compensation for damages or requirements to supervise their animals more closely. In some jurisdictions, from the start of the modern era onwards, the owner increasingly became the focus of legal responsibility rather than the animal itself.
When did animal trials come to an end in Europe?
Traditional animal trials became increasingly rare during the 17th and 18th centuries and eventually disappeared with the emergence of enlightened concepts of criminal law centred on individual human culpability. Isolated later executions of animals, such as that of the elephant Mary in 1916 in Erwin, Tennessee, are regarded as spectacular isolated cases outside Europe – not as a continuation of the medieval legal tradition.
