Feudalism brought change to England, but not technological advancement

The arrival of the Normans in England brought about social changes rather than technological advancements. The tools, techniques, and methods used by the English and Normans remained largely the same in the 11th century. Peasants continued to work in the fields using traditional tools, animals were raised and slaughtered in similar ways, and fortresses were still made of wood. The Normans may have introduced changes on a social level, but there was no significant leap forward in technology.
