Pope Constantine (b. 664)
Pope Constantine (Latin: Constantinus; 664 – 9 April 715) was the bishop of Rome from 25 March 708 to his death. One of the last popes of the Byzantine Papacy, the defining moment of Constantine's pontificate was his 710/711 visit to Constantinople where he compromised with Justinian II on the Trullan canons of the Quinisext Council. Constantine's was the last papal visit to Constantinople until 1967.
