The foundation of the present cathedral was laid by its first Norman abbot, Simeon, in 1083. But the reputation of Ely had been established long before Etheldreda (Æthelthryth), daughter of Anna, king of East Anglia, was married to Ecgfrith, king of Northumbria, against her will, as she had vowed herself wholly to a religious life. Her husband opposed himself to her vow, but with the help of Wilfrid, archbishop of York, she took the veil, and found refuge from her husband in the marsh-girt Isle of Ely. Here she founded a religious house, in all probability a mixed community, in 673, becoming its first abbess, and giving the whole Isle of Ely to the foundation. In 870 the monastery was destroyed by the Danes, as were also the neighbouring foundations at Soham, Thorney, Crowland and Peterborough, and it remained in ruins till 970, when Æthelwold, bishop of Winchester, founded a new Benedictine monastery here. King Edgar in 970 endowed the monks with the former possessions of the convent and also granted them the secular causes of two hundreds within and of five hundreds without the marshes, all charges belonging to the king in secular disputes in all their lands and every fourth penny of public revenue in the province of Grantecestre. The wealth and importance of Ely rose, and its abbots held the post of chancellors of the king's court alternately with the abbots of Glastonbury and of St Augustine's, Canterbury. But Ely again became a scene of contest in the desperate final struggle against William the Conqueror of which Hereward "the Wake" was the hero. Finally, in 1071, the monks agreed to surrender the Isle of Ely to the king on condition of the confirmation of all the possessions and privileges, held by them in the time of Edward the Confessor. Abbot Simeon (1081-1094), who now began the reconstruction of the church, was related to William and brother to Walkelin, first Norman bishop of Winchester. Under Abbot Richard (1100-1107) the translation from the Saxon church of the bodies of St Etheldreda and of the two abbesses who had followed her, and their enshrinement in the new edifice, took place; and it was due to the honour in which the memory of the foundresses was held that Ely maintained the position of dignity which it kept henceforth until the dissolution of the monasteries. The feast of St Etheldreda, or St Awdrey as she was generally called, was the occasion every year for a large fair here, at which "trifling objects" were sold to pilgrims by way of souvenirs; whence the word "tawdrey," a contraction of St Awdrey. In 1109 the Isle of Ely, most of Cambridgeshire, and the abbeys of Thorney and Cetricht were separated from the diocese of Lincoln, and converted into a new diocese, Ely being the seat of the bishopric, and after the dissolution of the monasteries Henry VIII. converted the conventual church into a cathedral (1541). The diocese is extensive. It covers nearly the whole of Cambridgeshire,
