The Domesday Survey was a comprehensive record of landholdings in England, commissioned by William the Conqueror in 1085-1086. It aimed to assess the wealth and resources of the kingdom for taxation purposes. The survey involved detailed surveys of land, livestock, and the population, providing a snapshot of medieval England. Completed in 1086, the Domesday Book is the result of this survey and serves as a crucial historical document. It lists over 13,000 places and includes information about landowners, the value of their lands, and the number of tenants. The book remains an essential resource for understanding feudal society in England.
