Pope Agatho (died January 681) served as the bishop of Rome from 27 June 678 until his death. He heard the appeal of Wilfrid of York, who had been displaced from his see by the division of the archdiocese ordered by Theodore of Canterbury. During Agatho's tenure, the Sixth Ecumenical Council was convened to deal with monothelitism. He is venerated as a saint by both the Catholic and Orthodox churches.
