SERF

During the feudal times certain persons who were bound to perform very onerous duties towards others, were so called. There is this essential difference between a serf and a slave; the serf was bound simply to labor on the soil where he was born, without any right to go elsewhere without the consent of his lord; but he was free to act as he pleased in his daily action: the slave on the contrary is the property of his master, who may require him to act as he pleases in every respect, and who may sell him as a chattel.
