Pope John IX (; – January 900) was the bishop of Rome and ruler of the Papal States from January 898 to his death in 900.
Early life
Little is known about John IX before he became pope. Born in Tivoli to a man named Rampoaldo, he was ordained as a Benedictine priest by Pope Formosus. With the support of the powerful duke of Spoleto he was elected pope in early 898 following the sudden death of Pope Theodore II.
Pontificate
With a view to diminish the violence of faction in Rome, John held several synods in Rome and elsewhere in 898. They not only confirmed the judgment of Pope Theodore II in granting Christian burial to Pope Formosus, but also at a council held at Ravenna decreed that the records of the Cadaver Synod held by Pope Stephen VI which had condemned him should be burned. Re-ordinations were forbidden, and those of the clergy who had been degraded by Stephen were restored to the ranks from which he had deposed them. The custom of plundering the palaces of bishops or popes on their death was ordered to be put down both by the spiritual and temporal authorities. John sanctioned the consecration of a metropolitan bishop and three more bishops for the Moravians.
