When did feudalism began to spread to Britain soon after?

Feudalism began to spread in Britain shortly after the Norman Conquest of 1066. Following William the Conqueror's victory at The Battle of Hastings, he established a system of land tenure that redistributed land to his followers in exchange for military service. This marked the formal introduction of feudal principles in England, leading to the establishment of a hierarchical society based on land ownership and vassalage.
