Stronger Government
The survey gave William information that no previous English king had possessed.
This allowed him to govern more effectively.
Better Tax Collection
Officials could now assess taxes more accurately.
The king knew who owned land and how wealthy they were.
This made tax collection more efficient.
Greater Control
The survey reminded everyone that William was in charge.
The king could investigate any part of the country.
This strengthened royal authority.
Monitoring the Nobles
The Domesday Book also helped William keep an eye on powerful Norman barons.
The king could see exactly how much land each noble possessed.
This reduced the risk of nobles becoming too powerful.
