Feudalism is a political and social system that existed in Europe during the Middle Ages. It was characterized by the presence of lords and vassals, with the lords holding land from the king and granting it to vassals in exchange for their loyalty and military service. The vassals, in turn, would provide military support to the lords and work the land to produce goods. Feudalism also had a strong hierarchy, with the king at the top, followed by the lords, vassals, and serfs (peasants who were tied to the land and owed labor service to the lords).
