SERF
serf. Hist. A person in a condition of feudal servitude, bound to labor at the will of a lord; a villein. ? Serfs differed from slaves in that they were bound to the native soil rather than being the absolute property of a master.¡°As the categories became indistinct, the more abject varieties of slavery disappeared and in the twelfth century the word ¡®villein¡¯ became the general term for unfree peasants. ¡®Serf¡¯ did not become a legal term of art, and in so far as it remained in use it did not connote a status lower than that of villein. The merger was to the detriment of the villani, but it ensured that full slavery was not received as part of the common law.¡± J.H. Baker, An Introduction to English Legal History 532 (3d ed. 1990).
