Answer:
Manor system is a basis of feudal system. In it peasants had the obligation to work on the land of lords, who held that land in the name of their ruler (senior). Peasants, who were either serfs of freeman had the obligation to work on the land of the noble and received small benefits. They lived in small cottages, had to work practically the whole day, and usually were not even allowed to leave the property. Therefore their status in the society was very bad. They were not even allowed to marry without the consent of the lord.
Step-by-step explanation:
Feudal system, that has developed after the fall of Western Roman Empire was based on loyalty. Ruler was owning the land, that he distributed to his vassals. Those vassals made sure that both them and rulers had benefits from that land, that of course were obtained from the hard work of serfs.
