Vikings
Europeans were scared of the Vikings because of their strong weapons, swift attacks, and cruel fighting tactics. They were known for their bad treatment of women, children and monks in the places where they fought. When the Vikings came to England, the English kings paid them to leave the country, but the Vikings took their money and sometimes fought them anyway. These payments were called Danegeld. From the 9th century to 1066, when the French Duke of Normandy, who became King William I of England, conquered it, Danish and Norwegian Vikings ruled large parts of England.
