The document summarizes the feudal and manorial systems that governed medieval Europe. Under the feudal system, lords gave land (fiefs) to knights in exchange for military service and loyalty. Peasants lived and worked on large estates (manors) under the manorial system, farming the land in exchange for protection from their lords. Life in villages was difficult, with peasant families living in basic one-room houses and working constantly, while castle life was more comfortable but still lacked modern conveniences.
