Was the Norman invasion good or bad for England?

The Norman invasion of 1066 had both positive and negative consequences for England. On one hand, it brought significant cultural and administrative changes, introducing feudalism and strengthening the centralized monarchy, which helped to unify the country. On the other hand, it led to widespread violence, displacement of the Anglo-Saxon nobility, and substantial social upheaval. Overall, while the invasion laid the groundwork for a more unified England, it came at a considerable human and social cost.
