In the course of the revival of the English church under Dunstan, Archbishop of Canterbury, and Aethelwold, Bishop of Winchester, a new Benedictine abbey for men was established in Ely in 970. This was one of a wave of monastic refoundations which locally included Peterborough and Ramsey. Ely became one of the leading Benedictine houses in late Anglo-Saxon England. Following the Norman conquest of England in 1066 the abbey allied itself with the local resistance to Norman rule led by Hereward the Wake. The new regime having established control of the area, after the death of the abbot Thurstan, a Norman successor Theodwine was installed. In 1109 Ely attained cathedral status with the appointment of Hervey le Breton as bishop of the new diocese which was taken out of the very large diocese of Lincoln. This involved a division of the monastic property between the bishopric and the monastery, whose establishment was reduced from 70 to 40 monks, headed by a prior; the bishop being titular abbot.
