Feudalism was a social and economic system that dominated medieval Europe, characterized by a hierarchy of lords, vassals, and serfs. Land was held by nobles (lords) in exchange for military service and protection, while vassals pledged loyalty and service to their lords. Peasants or serfs worked the land and provided agricultural produce, often in return for protection and a place to live. This system created a structured society based on land ownership and obligations, influencing political and economic relationships during the Middle Ages.
