The case of ancient demesne is especially interesting in this light. It presents, as it were, an earlier and less perfect crystallisation of society on a feudal basis than the manorial system of Common Law. It steps in between the Saxon _soc_ and _tun_ on the one hand, and the manor on the other. It owes to the king's privilege its existence as an exception. The procedure of its court is organised entirely on the old pattern and quite out of keeping with feudal ideas, as will be shown by-and-by. Treating of it only in so far as it illustrates the law of status, it presents in separate existence the two classes which were fused in the system of the Common Law; villain socmen are carefully distinguished from the villains, and the two groups are treated differently in every way. A most interesting fact, and one to be taken up hereafter, is the way of treating the privileged group as the normal one. Villain socmen are _the_ men of ancient demesne; villains are the exception, they appear only on the lord's demesne, and seem very few, so far as we can make a calculation of numbers. Villain socmen enjoy a certainty of condition which becomes actual tenant-right when the manor passes from the crown into a private lord's hand. As to its origin there can be no doubt--ancient demesne is traced back to Saxon times in as many words and by all our authorities. [Clues as to the condition of Saxon peasantry.] A careful analysis of the law of ancient demesne may even give us valuable clues to the condition of the Saxon peasantry. The point just noticed, namely, that the number of villain socmen is exceedingly large and quite out of proportion to that of other tenants, gives indirect testimony that the legal protection of the tenure was not due merely to an influx of free owners deprived of their lands by conquest. This is the explanation given by Bracton, but it is not sufficient to account for the privileged position of almost all the tenants within the manor. A considerable part of them surely held before the Conquest not as owners and not freely, but as tenants by base services, and their fixity of tenure is as important in the constitution of ancient demesne as is the influx of free owners. If this latter cause contributed to keep up the standard of this status, the former cause supplied that tradition of certainty to which ancient demesne right constantly appeals.
