Domesday Book, record of a general census of England made (1085-86) by order of William I (William the Conqueror). The survey ascertained the economic resources of most of the country for purposes of more accurate taxation. Royal agents took the evidence of local men in each hundred (county subdivision), the latter acting as inquest jurors. Descriptions of each piece of land, its present and former holders, the holding itself, and the population on it were among the facts recorded. For the thoroughness and speed with which it was taken, the Domesday survey as an administrative measure is unsurpassed in medieval history. Written from the data thus gathered, the Domesday Book is an invaluable historical source. It furnished the material for F. W. Maitland's masterly survey, Domesday Book and Beyond (1897), which deals with social and economic conditions in Anglo-Saxon and Conquest times. Many of the Domesday records have been printed by counties in the Victoria County Histories, and several portions have been independently published. The name domesday is a variant of doomsday, meaning day of judgment.

(1086) Original record or summary of William I the Conqueror's survey of England. The most remarkable administrative feat of the Middle Ages, the survey was carried out, against popular resentment, by panels of commissioners who compiled accounts of the estates of the king and his tenants. As summarized in the Domesday Book, it now serves as the starting point for the history of most English towns and villages. Originally called “the description of England,” the name Domesday Book (a reference to doomsday, when people face a final accounting of their lives) was later popularly attached to it.
