Now in e-guide format, a full introduction to the Norman Conquest, an event which resulted in dramatic changes to the nation's aristocracy, church and administration.

It brought a new language and cultural influences and revolutionised military architecture with the introduction of the castle. This profound impact was not brought about as the result of a single battle and it took a five-year war for William to establish control over his new kingdom.

In this compact, pocket e-guide, the campaigns are studied in detail, with maps showing how William's energy and strategic intelligence enabled him to defeat his formidable opponents and create a new order.
