Viking - and Early Middle Ages

The term Viking is customarily used to refer to the Norse (Scandinavian) explorers, warriors, merchants, and pirates who raided, traded, explored and settled in wide areas of Europe and the North Atlantic islands from the late eighth to the mid-11th century. The period from the earliest recorded raids in the 790s until the Norman Conquest of England in 1066 is commonly known as the Viking Age of Scandinavian history. The Normans, however, were descended from Danish Vikings who were given feudal overlordship of areas in northern France — the Duchy of Normandy — in the 10th century. In that respect, descendants of the Vikings continued to have an influence in northern Europe.
