A more thorough explanation:

Definition: Feudal law refers to the real-property law of land tenures that was prevalent in England, especially after the Norman Conquest. It was a system of land ownership and obligations between lords and vassals.

Example: Under feudal law, a lord would grant land to a vassal in exchange for their loyalty and military service. The vassal would then become a tenant of the lord and would owe them certain duties and obligations.

Explanation: This example illustrates how feudal law worked in practice. The lord had the power to grant land to their vassals, who would then owe them certain obligations. This system helped to maintain social order and stability in medieval England.
