In the year 897, Rome witnessed one of the most macabre episodes in its long and turbulent history, an event so bizarre that even medieval chroniclers struggled to describe it without disbelief. It became known as the Cadaver Synod, a trial in which Pope Stephen VI ordered the exhumation, interrogation, and condemnation of his deceased predecessor, Pope Formosus. The corpse, dressed in papal vestments and propped upon a throne, was placed on trial before a council of bishops. The spectacle was political theater at its most grotesque, reflecting the bitter factionalism that consumed the papacy during one of its darkest eras. Yet despite how surreal it appears today, the Cadaver Synod was rooted in a very real struggle for power, legitimacy, and control over Rome’s fragile future.
Pope Formosus had died in 896 after a tumultuous career filled with alliances, betrayals, and shifting loyalties. During his life, he had been accused of conspiring with rival factions, particularly those aligned with the Carolingians and various noble families who fought for influence over the papal throne. His papacy was spent navigating these volatile political networks, appointing bishops, negotiating with kings, and trying to assert authority in an environment where the Pope was as much a political figure as a spiritual one. When Formosus died, his opponents did not consider the matter settled. Instead, they sought to erase his legacy by attacking the validity of his reign itself.
Stephen VI, who became Pope less than a year after Formosus’ death, was aligned with the powerful Spoleto family, who resented Formosus for his alliances and political maneuvering. According to several sources, Stephen was pressured, or at least strongly encouraged, by the Spoletans to punish Formosus posthumously. Whether driven by political fear or a personal vendetta, the new Pope agreed to do something unprecedented: open a trial against a dead man. The corpse of Formosus was dug up from its tomb, dressed in full papal garb, and placed on a throne in the Basilica of St. John Lateran as though it were still capable of testifying.
The spectacle was chilling. Chroniclers wrote that the body, already decaying, had to be propped upright. A deacon was appointed to speak for the corpse, answering questions on its behalf as Pope Stephen VI thundered accusations. Formosus was charged with perjury, violating canon law, and illegally assuming the papacy. The charges largely stemmed from old political grievances, particularly Formosus’ actions years before he became Pope, when he had fled Rome and faced accusations of abandoning his post. The proceeding was less a trial than a public humiliation designed to delegitimize everything Formosus had done while in power.
The verdict was predetermined. Formosus was declared guilty on all counts. His papacy was annulled, his acts voided, and his ordinations condemned. To drive the humiliation further, the corpse was stripped of its vestments, the fingers used for blessings were cut off, and the body was dragged through the basilica before being thrown into the Tiber River. It was an act meant not only to erase Formosus from history but to assert Stephen VI’s own authority at a time when the papacy was dangerously unstable.
But the Cadaver Synod had consequences that Stephen did not anticipate. The public, already weary of political corruption and factional violence, recoiled from the grotesque spectacle. Many Romans saw the trial as an act of cruelty, sacrilege, and madness. Within months, a revolt erupted in the city. Stephen VI was imprisoned and later strangled to death, a swift and brutal reversal that underscored just how fragile papal authority had become.
After Stephen’s demise, subsequent popes worked to undo the damage. Formosus’ body was recovered from the river and reburied with honors. Later synods overturned Stephen’s verdicts, restoring Formosus’ legitimacy. Yet the papacy remained haunted by the event. For years, rival factions would alternately condemn and rehabilitate Formosus’ memory, depending on who held power. The Cadaver Synod became a symbol of the intense instability of the late 9th and early 10th centuries, a period historians later called the “pornocracy” or “saeculum obscurum,” when the papacy was dominated by nobles, intrigue, and violence.
Today, the Cadaver Synod stands as one of the strangest moments in church history, a reminder of how political desperation can descend into the grotesque. It is often cited as an example of the extremes to which medieval power struggles could go, where even the dead could be weaponized in the battle for legitimacy. No other event quite matches its surreal blend of ritual, politics, and desecration. In the end, the trial revealed far more about the living, their ambitions, fears, and rivalries, than it ever could about the silent figure propped upon the papal throne.
