A Serf was the lowest in the Social Caste in Medieval times, while the Lord and the Lady owned Manors (Households) which were typically larger than most of today's houses. The Lord and Lady were middle class people, and a Serf served the lord and the Lady.
Medieval lands owned by a nobleman or lord for whom the serfs labored and owed allegiance were known as manors or feudal estates. These were self-sufficient agricultural areas, usually centered around a manor house or castle, where the lord exercised control over the serfs who worked the land.
Manors were isolated from each other by large tracts of land owned by the Lord. These were little kingdoms within themselves that were very self efficient. Everything that was needed to run the manor was created locally and in many cases defended locally if the manor came under attack for any reason.

The land owned by a baron was typically referred to as a "manor." This estate often included the lord's residence, agricultural land, and various resources. In the feudal system, manors were essential for the economic and social structure, serving as the center of local governance and agricultural production.
Manors typically used a system of farming known as the manorial system. This involved a lord granting land to peasants in exchange for labor or goods. The peasants would work the land and give a portion of the produce to the lord as rent.
