During the Middle Ages, a serf was bound to work in one manor and could not leave or marry without the lord's permission.
The answer to the question is 'serf,' which refers to a peasant bound to a manor in the medieval feudal system. Serfs were not free to leave the land they worked and were subject to the authority of the estate's lord. Their existence was a crucial part of the agricultural economy during the Middle Ages, primarily from the 9th to the late Middle Ages.
