Pope Conon was Pope from 21 October 686 to his death in 687. He had been put forward as a compromise candidate, there being a conflict between the two factions resident in Rome - the military and the clerical. On his death, Conon was buried in the Patriarchal Basilica of St. Peter. He consecrated the Irish missionary Kilian a bishop and commissioned him to preach in Franconia.
A Greek according to the Liber pontificalis, Conon was the son of an officer from the Thracesian Theme. He was educated in Sicily, where his father may have been posted during the stay of Constans II, and was later ordained a priest at Rome. He may have been among the many Sicilian clergy in Rome, at that time, due to the Islamic Caliphate raids on Sicily in the mid-7th century. His age, venerable appearance, and simple character caused the clergy and soldiery of Rome, who were in disagreement, to put aside their respective candidates and to elect him as pope.
