Summary
Episode Description:
In the year 897, Pope Stephen VI ordered the rotting corpse of his predecessor, Pope Formosus, to be dug up, dressed in papal robes, propped up on a throne, and put on trial.
Yes, this actually happened.
This bizarre and macabre moment in church history—known as the Cadaver Synod or Synodus Horrenda—is one of the most infamous (and grotesque) episodes of the medieval papacy. In this episode, John Williamson dives deep into the political chaos of 9th-century Rome, explains how the corpse trial came to be, and breaks down why the church literally put a dead pope on the stand.
Get ready for a tale of revenge, power, posthumous punishment, and one of the most unhinged trials in recorded history.
What You’ll Learn in This Episode:
• Who Pope Formosus was, and why his enemies hated him
• Why Pope Stephen VI risked total scandal to hold the corpse trial
• What actually happened during the Synod—from propping up the corpse to cutting off its fingers
• How this event caused riots, a papal overthrow, and a historical backlash that shaped future church policy
• How the corpse trial symbolizes the violent politics of the medieval church
