His royal officers held a public inquiry into the value of all homes and what they owned, and recorded all their data into what is known as the Domesday Book, which itself was divided into two parts - Little Domesday and Great Domesday. Surprisingly, it was prepared in the space of one year and was completed in 1086. The Domesday Book is a statistical document and was used as an administrative tool, a basis for more decisive taxation of William's new realm and to fund his warfare. It involved the first kingdom-wide poll taken in Europe since the Roman era."
