William and his descendants encourage the influence of what culture on the English people?

William the Conqueror and his descendants, particularly through the Norman Conquest of 1066, significantly encouraged the influence of Norman-French culture on the English people. This resulted in the integration of French vocabulary into the English language, changes in legal and administrative practices, and the introduction of feudalism. The Normans also impacted architecture, evident in the construction of castles and cathedrals, thus reshaping English society and culture.
