1066 and all That: "by 1086 something had clearly changed. Domesday Book is a record of a land deeply marked by the scars of conquest. In 1086 there were only two surviving English lords of any account. More than 4,000 thegns had lost their lands and been replaced by a group of less than 200 barons. A few of the new landlords were Bretons and men from Flanders and Lorraine but most were Normans. In the case of the Church we can put a date to William's anti-English policy. In 1070 he had some English bishops deposed and thereafter appointed no Englishman to either bishopric or abbey. In military matters, the harrying of the north during the winter of 1069-70 also suggests ruthlessness on a new scale at about this time. In Yorkshire this meant that between 1066 and 1086 land values fell by as much as two-thirds. But whenever and however it occurred it is certain that by 1086 Anglo-Saxon aristocracy was no more and its place had been taken by a new Norman elite."
