What is the dooms day book used by William conquerer?

The "Doomsday Book" is not a book, but rather a comprehensive survey of England commissioned by William the Conqueror after his conquest in 1066. It's officially called the Domesday Book.

Here's what you need to know:

* Purpose: The Domesday Book aimed to assess the wealth of England to determine how much tax could be levied.

* Scope: It recorded information about land ownership, population, livestock, and other assets in almost every part of England.

* Details: The survey was remarkably thorough, listing everything from the number of plow oxen to the amount of honey produced by each village.

* Legacy: The Domesday Book is a vital historical document, providing an invaluable snapshot of English society in the 11th century. It's still consulted by historians today.

There's no separate "dooms day book" associated with William the Conqueror. The Domesday Book was his primary tool for understanding and controlling his newly conquered territory.
