 The substantive title of "Lord of the Manor" came into use in the English medieval system of feudalism after the Norman Conquest of 1066.The title "Lord of the Manor" was a titular feudal dignity which derived its force from the existence and operation of a manorial court or court baron at which he or his steward presided, thus he was the lord of the manorial court which determined the rules and laws which were to govern all the inhabitants and property covered by the jurisdiction of the court.To the tenants of a certain class of manor known in Saxon times as "Infangenthef" their lord was a man who had the power of exercising capital punishment over them.
