(When William the Conqueror had been some years established in his English realm, he found himself confronted with a feudal baronage largely composed of men who had gone with him from Normandy, where many of them had reluctantly bowed to his command. They were jealous of the royal power and eager for military and judicial independence within their own manors. The Conqueror met this situation with the skill of political genius. He granted large estates to the nobles, but so widely scattered as to render union of the great land-owners and hereditary attachment of great areas of population to separate feudal lords impossible. He caused under-tenants to be bound to their lords by the same conditions of service which bound the lords to the crown, to which each sub-tenant swore direct fealty. William also strengthened his position as king by means of a new military organization and by his control of the judicial and administrative systems of the kingdom. By the abolition of the four great earldoms of the realm he struck a final blow at the ambition of the greater nobles for independent power. By this stroke he made the shire the largest unit of local government. By his control of the national revenues he secured a great financial power in his own hands. A large part of the manors were burdened with special dues to the crown, and for the purpose of ascertaining and recording these William sent into each county commissioners to make a survey, whose inquiries were recorded in the _Domesday Book_, so called because its decision was regarded as final. This book, in Norman-French, contains the results of his survey of England made in 1085-1086, and consists of two volumes in vellum, a large folio of three hundred and eighty-two pages, and a quarto of four hundred and fifty pages. For a long time it was kept under three locks in the exchequer with the King's seal, and is now kept in the Public Record Office. In 1783 the British Government issued a fac-simile edition of it, in two folio volumes, printed from types specially made for the purpose. It is one of the principal sources for the political and social history of the time. The _Domesday Book_ contains a record of the ownership, extent, and value of the lands of England at the time of the survey, at the time of their bestowal when granted by the King, and at the time of a previous survey under Edward the Confessor. Of the detailed registrations of tenants, defendants, live stock, etc., as well, as of contemporary social features of the English people, the following account presents interesting pictures.)
