History is messy. Sometimes, it’s downright grotesque. If you’ve ever wondered how weird the Papacy could get during the Dark Ages, you’ve probably stumbled upon the "War of Corpses"—more accurately known to historians as the Cadaver Synod. It sounds like a horror movie trope. But it was real. In January 897, a dead man was dug up, dressed in royal robes, and forced to stand trial in a Roman courtroom.
Rome was a disaster back then. The ninth century wasn't exactly a time of stability or grace. Families were fighting for the throne, and the Pope wasn't just a spiritual leader; he was a political pawn with a target on his back. You’ve got to understand that the "War of Corpses" wasn't about theology or some deep spiritual disagreement. It was about raw, ugly revenge. Pope Formosus had been dead for about nine months when his successor, Pope Stephen VI, decided he hadn't had enough of him yet.
Stephen VI ordered the rotting body of Formosus to be exhumed. They dragged the corpse into the Basilica del Salvatore. They propped it up on a throne. A deacon was actually appointed to stand behind the dead body and "speak" for it, answering the screaming accusations of the living Pope. It’s hard to imagine the smell. The sheer insanity of the visual. But this happened.
Why the Cadaver Synod actually took place
Politics is usually the culprit. Formosus had a complicated career. Before he was Pope, he was the Bishop of Porto, and he’d been excommunicated once before by Pope John VIII. Eventually, he got back into the Church’s good graces and became Pope himself in 891. But he made a massive mistake: he backed the wrong guy for the title of Holy Roman Emperor.
Formosus initially supported Lambert of Spoleto but later switched sides to Arnulf of Carinthia. This didn't sit well with the Spoleto family. When Formosus died and Stephen VI (a Spoleto puppet) took over, the Spoletos wanted blood. Or, since Formosus was already dead, they wanted his legacy erased.
The "War of Corpses" was a legal maneuver to invalidate everything Formosus had done. If they could prove he was never a legitimate Pope, then all his ordinations and decrees were void. This would effectively strip his allies of their power. Stephen VI wasn't just crazy; he was doing a favor for his political donors. He charged the corpse with perjury and with illegally serving as a bishop in more than one place at once.

It was a circus. Stephen VI literally screamed at the corpse. He asked it why it had usurped the Roman See. The deacon, likely terrified for his own life, mumbled excuses on behalf of the rotting remains. Unsurprisingly, the corpse lost the case.
The Brutal Aftermath of the Trial
The verdict was as grim as the trial itself. The court declared Formosus's papacy void. They stripped the papal vestments off the decaying body. Then, they cut off the three fingers on his right hand—the fingers he used for blessings.
They didn't stop there.
The body was initially buried in a common grave, but then Stephen changed his mind and had it tossed into the Tiber River. This was the ultimate insult. In the eyes of the people, it meant he was denied a Christian burial. But this is where the story gets even weirder. Legend says the body washed up on the banks of the river and started performing miracles. People in Rome started to get uneasy. They might have hated Formosus when he was alive, but treating a dead Pope like trash felt like a bridge too far.
The Backlash Against Stephen VI
Public opinion flipped fast. The "War of Corpses" turned the Roman public against Stephen VI. Honestly, the sight of a Pope screaming at a skeleton was a bit much even for the 800s. A few months after the trial, a riot broke out. Stephen VI was stripped of his power, thrown into prison, and strangled to death in his cell.
The next few Popes spent their short reigns trying to clean up the mess. Pope Theodore II recovered the body from the Tiber and had it reburied in St. Peter’s Basilica with full honors. He even held a ceremony to reinstate the ordinations Formosus had performed. But the drama didn't end. Pope Sergius III, who took power a few years later, actually tried to reinstate the "War of Corpses" verdict. He hated Formosus just as much as Stephen did.
Sergius III had the body dug up again, put on trial again, and beheaded. It’s a period of history often called the "Pornocracy" or the "Saeculum Obscurum" because it was just so incredibly corrupt and violent.
The Long-Term Impact on Church Law
You might think this was just a weird footnote, but the "War of Corpses" changed how the Church handled dead people. Eventually, the Church prohibited the trial of deceased persons. They realized that letting a living Pope put a dead one on trial was a recipe for eternal chaos and undermined the very idea of the Papacy's stability.
It also highlighted the danger of the "Translation of Bishops." Back then, moving from one bishopric to another was seen as "spiritual adultery." You were supposed to stay "married" to your first diocese. Formosus moving from Porto to Rome was the legal technicality they used to destroy him. This event forced the Church to eventually modernize its views on how leaders were moved and promoted.
Historians like Jean-Marie Sansterre have pointed out that the trial was a "theatricalization of power." It wasn't about the law; it was about showing everyone in Rome who was in charge. It was a warning. If we can do this to a dead Pope, imagine what we can do to you.
What we can learn from this morbid history
The "War of Corpses" is a reminder that institutions—even those claiming divine authority—are run by humans with human grudges. It shows how easily the legal system can be weaponized to settle personal scores. When you look at the history of the Cadaver Synod, you see the intersection of superstition, political desperation, and the absolute lack of "chill" in Medieval Rome.

Actionable Steps for History Enthusiasts:
- Read the primary sources: Look for the writings of Liutprand of Cremona. He’s the main source for the gory details of the trial. Just keep in mind he was a bit of a gossip and hated the people he wrote about, so take his "miracle" stories with a grain of salt.
- Trace the Spoletan Dynasty: To understand why this happened, you need to look at the Spoleto family's influence on the Papacy. Their rivalry with the Carolingians is the engine behind the entire trial.
- Visit the Vatican Grottoes: If you’re ever in Rome, you can visit the area where Formosus was eventually re-interred. It’s a much quieter place now than it was in 897.
- Study the Saeculum Obscurum: Research this specific 60-year period of the Papacy. The "War of Corpses" was just the beginning of a cycle of assassinations, poisonings, and power grabs that makes Game of Thrones look like a sitcom.
The trial of Pope Formosus stands as a grim monument to what happens when political tribalism overrides basic human decency. It’s a story of a man who couldn't find peace even in the grave, and a Church that almost collapsed under the weight of its own internal wars. It’s dark, it’s gross, and it’s a vital piece of the puzzle that is European history.
