Edred was succeeded by his sixteen-year-old nephew Edwy, whom Dunstan openly rebuked for unchastity. The furious Edwy drove Dunstan into exile, but the North rose in rebellion on his behalf. When the dust settled, Edwy was dead, his brother Edgar was king, and Dunstan was Archbishop of Canterbury. The coronation service which Dunstan compiled for Edgar is the earliest English coronation service of which the full text survives, and is the basis for all such services since, down to the present. With the active support of King Edgar, Dunstan re-established monastic communities at Malmesbury, Westminster, Bath, Exeter, and many other places. Around 970 he presided at a conference of bishops, abbots, and abbesses, which drew up a national code of monastic observance, the Regularis Concordia. It followed Benedictine lines, but under it the monasteries were actively involved in the life of the surrounding community. For centuries thereafter the Archbishop of Canterbury was always a monk.
Dunstan took an active role in politics under Edgar and his successor Edward, but under the next king, Ethelred, he retired from politics and concentrated on running the Canterbury cathedral school for boys, where he was apparently successful in raising the academic standards while reducing the incidence of corporal punishment. On Ascension Day in 988, he told the congregation that he was near to death, and died two days later.
Propers for Dunstan - Archbishop of Canterbury
O GOD, who dost ever hallow and protect thy Church: Raise up therein through thy Spirit good and faithful stewards of the mysteries of Christ, as thou didst in thy servant Dunstan; that by their ministry and example thy people may abide in thy favour and walk in the way of truth; through Jesus Christ our Lord, who liveth and reigneth with thee in the unity of the same Spirit ever, one God, world without end. Amen.
