# Medieval Homosexuality: When Sodomy Became a Crime

*History & War · Eleanor Hartwell · 2026-08-24*

## TL;DR

In early medieval Europe, same-sex acts were treated as sins requiring private penance, but by the 13th century, church councils and secular rulers had reclassified sodomy as a grave crime, often linked with heresy, punishable by burning or other harsh penalties. This change unfolded gradually across centuries, with the Lateran councils and local statutes cementing persecution.

## Key facts

- Early medieval penitential books prescribed fasting and prayer for same-sex acts, treating them as sins to be confessed.
- The Third Lateran Council of 1179 issued a decree against sodomy, ordering clerics involved in such acts to be deposed and laymen to be excommunicated.
- By the late 13th century, secular rulers began issuing harsh penalties, including burning, for convicted sodomites.
- Theologians such as Peter the Chanter in the 12th century linked sodomy to divine punishment and natural disasters.
- By the late 13th century, anti-homosexuality laws had become standard across Europe and persisted into the Enlightenment.

## What Did "Sodomy" Actually Mean in the Middle Ages?

If you time-traveled to medieval Europe and asked someone about "homosexuality," nobody would know what you meant. The words simply didn't exist. Instead, people used "sodomy," a catch-all term that covered three very different acts: sex with animals, same-sex intercourse, and non-procreative heterosexual acts like oral sex, anal sex, or masturbation. The Latin labels were *ratione generis* (by species), *ratione sexus* (by sex), and *ratione modus* (by manner).

Despite that broad umbrella, the dominant meaning of sodomy in everyday medieval usage was same-sex intercourse. When churchmen wrote about the sin of Sodom, they almost always had men lying with men in mind, even if the technical definition stretched further.

My main guide through this territory is James Brundage's *Handbook of Medieval Sexuality*. Anyone digging deeper should also grab John Boswell's *Christianity, Social Tolerance and Homosexuality*, a classic that tackles the subject with far more detail. Both historians stress the same starting point: medieval people simply had no vocabulary for sexual identity as we understand it today. A man who slept with other men wasn't "gay." He was a sinner who committed sodomy, nothing more, nothing less.

That three-fold definition mattered because it shaped how authorities responded. Bestiality, same-sex acts, and barren heterosexual acts all fell under the same condemnation, yet they weren't treated identically. The distinction between them, and the weight given to each, would shift dramatically across the centuries. Keep that in mind as we go, because it changes everything about how we read the sources.

## From Roman Law to Penitential Books: The Early Criminalization

Long before the medieval church built its elaborate machinery of persecution, the legal groundwork was already being laid in the late Roman Empire. The emperors Constantine, Justinian, and Theodosius each issued laws against what they called a "crime against nature," and the penalty was death. These weren't abstract moral pronouncements; they were concrete legal codes that would echo through centuries of European jurisprudence. The driving force behind this legal severity was Christianity, and no single thinker shaped the church's attitude toward sex quite like Augustine of Hippo. Writing in the late 4th and early 5th centuries, Augustine condemned all non-procreative sexual activity regardless of the participants. What's striking about his position is its consistency: he didn't single out same-sex acts for special condemnation beyond other non-procreative acts. An act of oral sex between a husband and wife troubled him in the same category as same-sex intercourse, though he did distinguish between types of sexual sins. The early Western church followed his lead, treating all non-procreative sex as equally problematic rather than singling out homosexual acts for special condemnation. As the Celts and Germans converted to Christianity in the 6th century, the church was still decentralized and needed practical tools for managing sin in communities that had no deep tradition of Christian morality. The answer came in the form of penitential books, handbooks that priests used to assign specific penances for specific sins. These manuals were remarkably detailed in their sexual tariffs. According to the Penitential of Theodore, the penance for sodomy ranged from 7 to 20 years depending on the circumstances. Oral sex carried a 3 to 7 year penance, anal sex 3 to 15 years, intercrural sex (meaning sex without penetration) 1 to 3 years, and masturbation a relatively light 30 days to 2 years. What's notable about this period is what the tariffs reveal about severity. Despite the existence of these penalties, people who engaged in same-sex acts did not yet face the extreme persecution that would come in later centuries. The penitential system was designed for confession and reconciliation, not execution. A man who confessed to same-sex acts could expect years of fasting and prayer, but he could expect to remain alive and within the church community. Still, the church's institutional anxiety about sodomy was growing, and it showed in the most mundane details of monastic life. Benedict of Nursia, the founder of the Benedictine order, wrote into his Rule that monks must sleep in separate beds, fully clothed, with candles burning throughout the night. He also stipulated that young monks' beds should never be placed adjacent to one another. These weren't arbitrary rules about comfort; they were deliberate precautions against the perceived temptations of men sleeping in close quarters. This early period also saw secular rulers getting involved. Charlemagne, crowned Emperor of the Romans in 800, issued capitularies that addressed sodomy, and according to the account preserved in his legal texts, he was particularly concerned about it among monks. One article of his capitularies laments that some priests had become "sodomites," a fact that seemed especially scandalous given that the priesthood was supposed to embody the hope of Christian salvation. The picture that emerges from these centuries is complex. The church had clearly identified sodomy as a serious sin deserving of substantial penance, and it had begun taking practical steps to prevent same-sex activity within its own institutions. Yet the response remained measured. The death penalty existed in Roman law, but the penitential system that replaced it in practice was designed to save souls, not destroy bodies. That balance, however, was about to shift dramatically.

## Monks, Beds, and a 9th-Century Love Poem

Church records from the early Middle Ages show a heightened seriousness about same-sex sodomy, and the reason likely comes down to simple geography. Monasteries were intensely homosocial places. Men lived, prayed, worked, and slept together, day after day, with almost no contact with women. That closeness made church authorities deeply nervous about what might happen between the brothers.

Saint Benedict of Nursia, the founder of the Benedictine order, built his famous Rule around that anxiety. In Chapter 22 of his Rule, he laid out precise sleeping arrangements. Monks had to sleep in separate beds. They had to remain clothed. Candles in the dormitory had to burn all night long. And the beds of younger monks could never be placed next to each other. Every detail reads like an attempt to wall off temptation before it could take root.

Charlemagne, the Frankish king crowned emperor in 800, pushed the same concern into secular law. He issued capitularies, royal decrees that governed his vast realm, and among them were laws against sodomy with special attention to monks. According to the account, one article of his capitularies contains a striking lament: that some priests are sodomites, despite the fact that their way of life and their virginity are supposed to be the greatest source of hope for all Christians. The wording suggests a ruler genuinely disturbed that the very men entrusted with salvation were falling into the sin he feared most.

Yet the institutional fear did not match everyday reality. Before the Gregorian Reforms of the 11th century, clergy did not strictly follow celibacy rules. Married priests existed. Priests with children existed. Priests with lovers, male or female, existed, and the church largely looked the other way.

One remarkable survival shows just how far that tolerance could stretch. In the 9th century, a priest in Verona, a city in northern Italy, wrote a love poem to a young man he had lost to a rival. The poem invokes Venus, the goddess of love, and the three Fates: Klotho, who spins the thread of life, Lachesis, who measures it, and Atropos, who cuts it. The priest begs these deities to protect the boy he loves, even as he mourns that "the joy that was mine yesterday belongs to my rival tomorrow." He compares himself to a wounded deer grieving for its fawn. It is one of the rarest surviving examples of same-sex love literature from the entire medieval period, a tender, aching document that survived the centuries despite everything the church would later do to erase such voices.

The poem stands in stark contrast to the rules being written around it. The same church that demanded separate beds and burning candles also produced a man who loved another man openly enough to write it down. The lived reality of same-sex love in the Middle Ages was never as simple as the laws suggested.

## The Turning Point: Peter Damian, the Gregorian Reforms, and the Third Lateran Council

In 1051, a Benedictine monk named Peter Damian published a fiery treatise called *Liber Gomorrhianus*, and with it, he changed the course of medieval attitudes toward same-sex love forever. Damian, writing from his monastery in Italy, condemned the clergy who committed sodomy in the most dramatic language he could muster. They were, he insisted, "destroying the walls of holy Jerusalem and creating the ruins of Sodom." It was a vivid, terrifying image, and it landed with real force in Rome.

But Pope Leo IX, who received the treatise, did not rush to act. He worried that a formal church investigation into sodomy would wound the institution itself. If too many priests were exposed, the church could face a shortage of clergy. Better, perhaps, to let the matter rest quietly. That reluctance, however, did not last.

Under Pope Gregory VII, who took office in 1073, the church entered a period of intense self-reform. The Gregorian Reforms pushed hard on clerical celibacy, demanding that priests abandon wives, lovers, and any hint of sexual activity. Historian James Brundage has called this era a "moral crusade," and at its center sat the question of sex, especially same-sex sex. From the late 11th century onward, canon law turned explicitly against same-sex acts. Sex itself came to be understood as a sin inspired by the devil, a temptation that could corrupt anyone.

The rhetoric grew stranger as the 12th century unfolded. Peter the Chanter, a Parisian theologian, invented a tale claiming that every sodomite on earth died at the exact moment Mary gave birth to Jesus. Church lawyers added their own spin, arguing that natural disasters were divine punishment for unpunished same-sex acts. Earthquakes, floods, and famines, they said, came because society tolerated what God hated.

The formal break came in 1179. At the Third Lateran Council, the church explicitly prohibited sodomy among the clergy for the first time. Clerics found guilty of "unnatural vice" were to be deposed from their positions or confined permanently to monasteries. Laypeople who committed the same acts faced excommunication. The law now had teeth, and it applied to everyone.

Yet even as the church tightened its grip, another world was taking shape in the shadows. Despite the persecution, literature celebrating same-sex love continued to be written. But it had to be coded, hidden, wrapped in language that only insiders could decode. Brundage, writing in 1996, noted how difficult these texts are to interpret precisely because their authors worked so hard to conceal their meaning. The result is a strange duality: a church that criminalized same-sex acts in ever harsher terms, and a small literary subculture that kept the flame of same-sex desire alive in whispers, symbols, and carefully chosen words.

## Heresy, Inquisition, and the First Documented Execution

In 1277, a man was burned at the stake in Toulouse, France, for same-sex acts. That execution stands as the first documented case of its kind in all of Western Europe. It marked a terrifying turning point: same-sex love had stopped being a private sin to confess and had become a public crime to hunt.

The shift happened quickly after 1200. The church began equating same-sex desire with heresy, specifically with the dualist Bogomils of Bulgaria, a sect that believed the material world was created by an evil god. The association was so strong that the word "bulgarus" became a synonym for "sodomita." If you were accused of one, you were effectively accused of the other.

The church's arguments from the 13th century sound unsettlingly familiar. Church leaders argued that everyone is naturally heterosexual, and that same-sex desire only arises from following the devil's temptation. They called it contagious and threatening. They claimed that anyone who experiences this desire carries it for life, regardless of how much they might loathe the act. And they warned that if these sins went unpunished, they would spread so widely that they would lead to what they called "the suicide of the human race."

From the 13th century onward, the Inquisition sometimes tried people accused of same-sex acts alongside heretics. But even those who escaped execution faced a brutal reality. They were marked with permanent shame, rejected by their own families, and subjected to economic boycotts that made daily life nearly impossible. Some were attacked and killed, yet secular authorities felt no obligation to prosecute the attackers. In the eyes of the law, the victim was the criminal.

By the late 13th century, anti-homosexuality laws had become standard throughout Europe. They entered secular law codes and remained there for centuries, surviving all the way into the Enlightenment of the 18th and 19th centuries. The execution in Toulouse in 1277 was not an anomaly. It was the beginning of a long, dark legal tradition that would shape European law for over five hundred years.

## FAQ: What Was the Medieval Definition of Sodomy?

The medieval definition of sodomy was far broader than what we might assume today. It covered sex with animals, same-sex intercourse, and any heterosexual act that did not aim at procreation, including oral sex, anal sex, and masturbation. The term "sodomy" served as the dominant word for same-sex acts, but it was never exclusive to them.

Medieval thinkers actually split sodomy into three distinct categories. The first, bestiality, involved sex with animals. The second covered same-sex intercourse between two people of the same gender. The third caught heterosexual couples who engaged in non-procreative acts, which meant oral sex, anal sex, or masturbation. Each category carried its own Latin label, but they all fell under the same moral umbrella.

Despite this three-part structure, the word "sodomy" most strongly attached itself to same-sex acts in everyday usage. When church authorities wrote about the sin, they usually meant men with men. That association grew so powerful that by the 13th century, the term "bulgarus" became a synonym for "sodomita," linking people accused of sodomy with the dualist heretics of Bulgaria.

The legal consequences escalated over time. The Third Lateran Council of 1179 marked the first time the Church explicitly prohibited sodomy among clergy. Canon 11 declared that clerics guilty of "that incontinence which is against nature" should be deposed or confined to monasteries, while laypeople faced excommunication. This council set a formal precedent that shaped church law for generations.

By 1277, the first documented execution for same-sex acts in Western Europe took place in Toulouse. The condemned person was burned at the stake, a punishment that signaled how far the Church and secular authorities had moved from the relatively tolerant early medieval period. What had once been a sin addressed through penitential tariffs had become a capital crime.

Editorial note: Some details of early medieval penalties and the exact timing of secular laws vary across surviving records, and any facts that remain unconfirmed are presented as such, with the evidence hedged accordingly.
