Norse England

[Thoresby]

Could the Norse/Vikings have done to the Anglo-Saxons what they did to the Brythonic peoples, i.e. without a total genetic replacement a lasting, near total cultural and religious transformation? So with a PoD after Lindisfarne as much of the Anglo-Saxon zone as possible becomes culturally Norse. Christianity doesn't have to be totally wiped out but it can't be dominant and while Anglo-Saxon can influence the local Norse dialect it has to essentially disappear at anything above the placename level.
It doesn't have to happen for all of the Anglo-Saxon realm though obviously the more the better and similarly there are no restrictions on the Norse also taking over Brythonic/Pictish/Gaelic areas.

England could be dominated and ruled by the Norse but I think the Anglo-Saxons were too plentiful, rich and far away from Scandinavia to be totally extinguished.

 

[Georgie Porgie]

Given that the "Vikings" ruled most of the north of the British Isles from York this would be incredibly easy, especially if Cnut's line could retain the Englash throne.
All it would take is Harthacnut to be more sucessful in retaining all his fathers lands.

 

[Peg Leg Pom]

If Cnuts empire survived his death then it would have eventually become an English empire due to shear weight of numbers and the greater wealth of England. There would have been a need for a permenant navy to move troops between the various parts of the empire inorder to put down any rebelions and the seat of government may well have been York instead of London but other than those differences there would have been few changes to otl before 1066.

William would either have not had an excuse to launch an invasion or have been defeated so the fudal system would not have been imposed on England. Thats not to say it would have been a peasants paradice as they would still have been exploited in as many ways as the earls could think of. The Norse system of government would have been retained so the power of the King would have been moderated through the continued existance of the Kings Council or Witenagemot.

By the 11th century there was little if any difference between Dane and Saxon in England and the battles of 1066 can be described as been between three different Norse contenders for the English Thrown.
