Medieval Laborers were primarily composed of SERFS, who were legally bound to the land they worked on and had few rights. They were required to work for their lord in exchange for protection and the use of land. SERFS were not allowed to leave the land without permission and were subject to the lord's laws. They were also expected to pay taxes and provide labor services such as plowing fields and harvesting crops. SERFS were the lowest class of medieval society and were considered to be little more than slaves.
