The Vikings were a people of Nordic European origin who were characterized by their great ability to navigate on the high seas and by the actions of conquest and looting of various parts of Europe during the Middle Ages. Vikings were originally from Scandinavia, that is, from the region that today comprises Norway, Sweden and Denmark, but ended up expanding to Iceland, Normandy, Great Britain, Eastern Europe and the Iberian Peninsula. Some authors believe it is possible to speak of a Viking Age, which would have lasted from AD 793 to AD 1066.
