In the fragmented and localized Europe of the 10th and 11th centuries, the Cluniac network extended its reforming influence far. Free of lay and episcopal interference, and responsible only to the papacy (which was in a state of weakness and disorder, with rival popes supported by competing nobles), Cluny was seen to have revitalized the Norman church, reorganized the royal French monastery at Fleury and inspired St Dunstan in England. There were no official English Cluniac priories until that of Lewes in Sussex, founded by the Anglo-Norman earl William de Warenne "c" 1077. The best-preserved Cluniac houses in England are Castle Acre Priory, Norfolk, and Wenlock Priory, Shropshire. It is thought that there were only three Cluniac nunneries in England, one of them being Delapré Abbey at Northampton.
