New Worlds For All Indians, Europeans, and the Remaking of Early America by Colin G. Calloway pg.2

In 1066, William the Bastard, duke of Normandy, invaded England to seize the throne from the Anglo-Saxon King Harold. Defeating and killing Harold in battle, William marched to London and took possession of the city where he had himself crowned King. In the years that followed, the Normans imposed their government, system of Justice, language, and culture on the conquered English people. What emerged, however, was an Anglo-Norman mixture, exemplified in the English language. The names for animals derive from the Anglo-Saxon words of the people who tended the livestock: sheep, cow, and pig: the names for the animals' meat derive from the words of the French-speaking Normans who dined on them: mutton, beef, and pork. Eventually, the Norman conquerors and their culture were absorbed by the conquered. Change occurred and England was never the same again, but it remained English. Such cultural confluences have been part of the give and take between conquered peoples and their conquerors for thousands of years throughout the world.
