Abstract
In a recent issue of this Journal North and Thomas outlined a model of the rise and fall of the manorial system, with special reference to England. Unfortunately, their model contains a number of inaccuracies which weaken quite seriously its applicability. The propositions of the model are based upon a confusion of terms and an oversight of authorities, both of which have led to a questionable factual and theoretical interpretation. In the following paragraphs an attempt will be made to elaborate upon these criticisms, and to suggest an alternative approach.
