Did William the Conqueror encourage or harm feudalism in England?

William the Conqueror significantly encouraged feudalism in England by establishing a hierarchical system of land ownership and loyalty following his victory in the Norman Conquest of 1066. He distributed large estates to his loyal knights and nobles, thereby solidifying their power and creating a structured society based on land tenure and vassalage. This system helped maintain order and control over the newly acquired territory, ultimately embedding feudalism deeply into English society. Thus, his actions fundamentally shaped the nature of feudal relationships in England.
