From the history of Great Britain
The Danes returned again and again to attack England. The English people had to pay tribute. But the Danes wanted to rule over the country and after many battles took the crown from the English. They held it for twenty-four years. Three Danish kings, one after the other, ruled over England. One of these kings - Canute was at the same time king of England, Denmark, Norway and Sweden. The rule of Danish kings over England came to an end soon after Canute's death in 1035. Now the Normans began to attack the coasts of England from Normandy (France). In 1066 the Normans won the victory and William, Duke of Normandy, was crowned king of England and called William the Conqueror. The invaders burnt houses and killed people. The land was taken from the English and given to the Normans. The invaders spoke French, and it was the language of the upper classes and the government. English was the language of the lower classes.
