Final answer:
The given statement is true.
Step-by-step explanation:
William the Conqueror was a powerful and authoritative ruler who successfully invaded England in 1066, marking the beginning of Norman rule. This statement is true.
After waves of Viking raids and the establishment of a Viking kingdom in eastern England, it took until 879 for the English kingdom of Wessex to defeat the Viking invaders. However, raids started up again, and in 1066, William the Conqueror, a Viking-descended king from Normandy, invaded and defeated the Anglo-Saxon king, instituting Norman rule.
Furthermore, the Bayeux Tapestry, which commemorates the struggle between William and Harold for the throne of England, also confirms William the Conqueror's successful invasion.
