There was nothing very complicated about the Harrying of the North. It came down as far as where I live now (Manchester area) and the economic effect of the slaughter is visible in the Domesday Book (nothing very complicated about that either - there's nothing else like it in all of Europe).

I came to history with an anti-English bias (I'm from South Wales), but the more I learned about the consequences of the Conquest, first when studying law and then when studying archaeology, the more sympathy I felt for the English and the less regard I had for my own Norman ancestors.
