This is the first written appearance of the division of society into the 'three orders'; the 'working men' provided the raw materials to support the other two classes. The advent of Christianity brought with it the introduction of new concepts of land tenure. The role of churchmen was analogous with that of the warriors waging heavenly warfare. However what Alfred was alluding to was that in order for a king to fulfil his responsibilities towards his people, particularly those concerned with defence, he had the right to make considerable exactions from the landowners and people of his kingdom. The need to endow the church resulted in the permanent alienation of stocks of land which had previously only been granted on a temporary basis and introduced the concept of a new type of hereditary land which could be freely alienated and was free of any family claims.
