The Cadaver Synod sounds like a bad metal band name. It wasn’t. It was a real, gruesome, and deeply political trial where a sitting Pope literally dug up his predecessor to put him on trial. This is what people usually mean when they talk about the War of the Dead, or more specifically, the era of the "Pornocracy" in the 9th and 10th centuries. It’s one of those historical rabbit holes that makes you realize how messy and visceral power used to be. No spreadsheets. No diplomatic cables. Just corpses and chaos.
Pope Stephen VI was the guy who pulled the trigger—well, the shovel. In January 897, he ordered the body of Pope Formosus to be exhumed. Formosus had been dead for nine months. You can imagine the state of the body. They dressed the decaying remains in papal vestments, sat it on a throne, and appointed a deacon to "speak" for the dead man. It was theater. It was madness. But mostly, it was a brutal consolidation of power during a time when the Papacy was essentially a local Roman prize fought over by warring aristocratic families like the Spoleto and the Tusculum clans.
History is weirdly full of these moments where the living can’t let the dead go. We see it in the "War of the Dead" concept across different cultures, from the desecration of Oliver Cromwell’s body in England to the literal battles over relics in the Middle Ages. But the Cadaver Synod remains the gold standard for how far humans will go to humiliate an enemy.
Why the War of the Dead Was Never Just About Religion
If you think this was about theology, you’re giving these guys too much credit. Honestly, it was a street fight. Formosus had been caught in the middle of a tug-of-war between the Holy Roman Empire and local Italian lords. Stephen VI belonged to a rival faction. By declaring Formosus an illegitimate Pope posthumously, Stephen could void all of Formosus’s official acts. This included the ordinations Formosus had performed. If his ordinations were void, his political allies lost their standing.
It was a legalistic loophole carved out of a rotting corpse.
The trial itself was a farce. Stephen screamed at the body. The deacon standing behind the corpse gave meek answers. The verdict? Formosus was guilty of "ambition" and performing the duties of a bishop in two different places simultaneously (pluralism). They hacked off the three fingers he used for blessings, stripped him, and tossed him into the Tiber River.

People think of the Vatican as this bastion of stability. In the year 897, it was a horror movie.
The aftermath was just as chaotic. A few months later, Stephen VI was strangled in prison. The public was horrified by the spectacle. They hadn't seen a "War of the Dead" like this before. Legend says the body of Formosus washed up on the banks of the Tiber and started performing miracles. Whether you believe that or not, the political tide turned. Pope Theodore II eventually recovered the body and reburied it in St. Peter’s Basilica with full honors. But the damage was done. The office of the Papacy had been dragged through the mud, literally and figuratively.
The Lingering Ghosts of the Saeculum Obscurum
Historians call this period the Saeculum Obscurum—the Dark Age of the Papacy. It lasted roughly from 904 to 964. During this time, the "War of the Dead" was a constant psychological backdrop. It wasn't just about the physical bodies; it was about the destruction of legacy. If you could kill a man's memory, you could control the future.
Think about the House of Theophylact. They basically ran Rome like a mob family. Theodora and her daughter Marozia were the real power brokers. They decided who wore the mitre and who ended up in a dungeon. This era is where the myth of "Pope Joan" likely found its roots, fueled by the shock of seeing women wield such immense, behind-the-scenes influence over the church.
The violence wasn't limited to Rome. This theme of fighting the dead—or using the dead to fight—appears in the Viking Sagas and the chronicles of the Byzantine Empire. In the North, "draugr" stories reflected a genuine fear that the dead would return to claim their property. In the East, the iconoclasm battles were a different kind of war on the "dead," as images of saints were destroyed to reset the political and spiritual landscape.

It’s easy to look back and call these people "backwards." But look at how we treat modern legacy. We tear down statues. We rewrite textbooks. We "cancel" historical figures. It’s the same impulse, just without the smell of formaldehyde.
Real-World Examples of Post-Mortem Warfare
We can't talk about the War of the Dead without mentioning Oliver Cromwell. In 1661, long after he had died and been buried in Westminster Abbey, the restored monarchy of Charles II decided they weren't done with him. They dug him up. They "executed" his corpse at Tyburn. They stuck his head on a spike outside Westminster Hall, where it stayed for decades.
Why? Because the living needed a symbol.
- The Case of Vlad the Impaler: His body was lost, and his head was sent to Constantinople as a trophy. The war didn't end when his heart stopped beating.
- The Relic Wars: During the Crusades, cities would literally go to war over the bones of saints. Possessing a holy corpse meant tax revenue from pilgrims and divine protection for the city walls.
- Jeremy Bentham: The philosopher wanted to stay involved. He had himself preserved as an "auto-icon." He’s still sitting in a glass box at University College London. Sometimes they bring him to board meetings. That’s a war against the finality of death if I’ve ever seen one.
The psychological weight of a body is immense. That’s why we have protocols for the burial of world leaders. It’s why the location of certain bodies is kept top secret. If a grave becomes a shrine, the "war" continues. If it becomes a site of desecration, the "war" escalates.
The Biological Reality of the Dark Ages
Life was short. Disease was everywhere. When we talk about the War of the Dead, we also have to acknowledge the literal piles of bodies that defined the era. The plague wasn't a one-time thing; it was a recurring nightmare. In many medieval cities, the dead outnumbered the living in ways that were impossible to ignore. Churchyards were so full that bodies would sometimes "surface" during heavy rains.

This constant proximity to death changed how people thought. They weren't squeamish. They lived in a world where the veil between life and death was paper-thin. So, when Stephen VI dug up Formosus, it was a scandal, but it wasn't outside the realm of their daily reality. They lived with the dead every single day.
How to Understand the "War" Today
The War of the Dead isn't just a historical curiosity. It’s a lesson in the fragility of institutions. When the legal and moral frameworks of a society break down, people stop fighting over ideas and start fighting over symbols. And there is no symbol more potent than a human body.
If you want to understand this better, you have to look at the primary sources—or what’s left of them. Liutprand of Cremona is the main source for the Cadaver Synod. He was a bit of a gossip and definitely had an agenda, but his vivid descriptions give us the only real window into that room in 897. He describes the "ghastly silence" of the corpse and the "maniacal shrieks" of the Pope. It’s the kind of writing that reminds you that history is made by people who are often scared, angry, and irrational.
Actionable Insights for History Buffs and Researchers:
- Analyze the "Damnatio Memoriae": If you’re researching this, look up the Roman practice of erasing someone from history. The Cadaver Synod was essentially a medieval, physical version of this.
- Study the Spoleto-Tusculum Feud: To understand the "why," you have to understand the families. The Papacy was a proxy war for Italian land ownership.
- Visit the Sites (Virtually or In-Person): The Basilica of St. John Lateran is where the synod happened. It was actually damaged by an earthquake shortly after the trial—which contemporaries took as a sign of God’s anger.
- Look for the Patterns: Post-mortem trials still happen in various forms in modern international law and posthumous pardons. The "War of the Dead" has just moved into the courtroom.
The War of the Dead teaches us that power doesn't stop at the grave. It lingers in the stories we tell and the way we treat those who came before us. Formosus eventually found peace in a tomb, but his trial remains a permanent stain on the history of the 9th century, a reminder that human grudge matches can transcend even the finality of death.
