pope of the Catholic Church (born 816)

Formosus

Pope Formosus was the pope and ruler of the Papal States from 6 October 891 until his death on 4 April 896. His reign as Pope was troubled, marked by interventions in power struggles over the Patriarchate of Constantinople, the Kingdom of West Francia, and the Holy Roman Empire. Because he sided with Arnulf of Carinthia against Lambert of Spoleto, Formosus's remains were exhumed and put on trial in the Cadaver Synod. Several of his immediate successors were primarily preoccupied by the controversial legacy of his pontificate, noting his desertion from the diocese in Portus to pursue personal ambition in Rome.
