Pope Constantine

Constantine became bishop of Rome on 25 March 708, near the tail end of the Byzantine Papacy, when the eastern empire still held sway over the church. The defining act of his tenure came in 710 or 711, when he traveled to Constantinople to meet Justinian II and negotiate a compromise on the Trullan canons — decrees from the Quinisext Council that had sparked friction between Rome and the East. He found middle ground, sealed the deal, and returned. No pope would visit the city again for nearly thirteen centuries. Constantine died in Rome on 9 April 715.
