Customarily refers to the Scandinavian explorers, warriors, merchants, and pirates who raided, traded, and settled in wide areas of Europe and the North Atlantic islands from the late eighth to the mid-eleventh century.There is some debate over the meaning of this word, which is attested but rarely used in the early medieval period. It was revived as a term in Scandinavian languages in the 17th century and in English in the early 19th. In contemporary sources it refers to a raider or pirate, often in association with ships and predatory activity. Some modern scholars try to keep to this restricted definition; others are happy with a wider range of meaning, applying the word to Scandinavians and their culture from approximately 790 to the mid or late 11th century, especially outside the Scandinavian homelands.
