At the Domesday survey (1086) much of the land was still uncultivated, but its prosperity increased, and in 1269 each of the twelve prebends of the collegiate church had a house and farmland within the parish. The bishops, to whom the manor belonged until the Reformation, had difficulty in enforcing their warren and other rights; in 1351 Bishop Grandisson obtained an exemplification of judgments of 1282 declaring that he had pleas of withernam, view of frankpledge, the gallows and assize of bread and ale. Two years later there was a serious riot against the increase of copyhold.
