Answer
Several of Formosus's successors were primarily preoccupied with his controversial legacy, and this was one of the reasons why they attempted to reverse his ordination and exhume his body. This led to the Cadaver Synod, a macabre ceremony in which Formosus's corpse was exhumed, tried, and found guilty of heresy and other crimes. He was then stripped of his ecclesiastical garments and thrown into the Tiber River.
