The Norman Conquest refers to the military invasion and subsequent occupation of England by the Duke of Normandy, William the Conqueror, in 1066. However, there are several synonyms for this event, including the Norman Invasion, the Norman Occupation, the Norman Triumph, and the Norman Takeover. Another term used is "1066 and all that," a reference to the year of the event in which the Anglo-Saxon way of life was dramatically changed. Despite the various synonyms, the Norman Conquest remains a significant event in English history, introducing the Norman-French language, feudalism, and new ruling class to the country.
