Preparations After Constans' son and successor, Constantine IV had overcome the Muslim siege of Constantinople in 678, he immediately set his sights on restoring communion with Rome: he wrote to Pope Donus suggesting a conference on the matter. When the letter reached Rome, Donus had died. Still, his successor, Pope Agatho, agreed to the Emperor's suggestion and ordered councils held throughout the West so that legates could present the tradition of the Western Church. There was a synod in Milan under Archbishop Mausuetus; another synod was held in 680 at Hatfield, over which Theodore, Archbishop of Canterbury presided. Pope Agatho then convened a synod at Rome at Easter 680, with representatives from the regional synods.
