The word viking in Old English actually means pirate. My Norse people that settled in Scotland so they were vikings, ,
Very interesting. The word also sometimes refers to people who inhabited a village community during the Viking Age
Viking travellers were seen by many as brutal raiders but were actually just farmers. 
Yeah, there was a lot of communities being settled and established and so a lot of merchants and trading going on,
Viking expansion
Viking expansion is the process by which Norse explorers, traders and warriors, the latter known in modern scholarship as Vikings, sailed most of the North Atlantic, reaching south to North Africa and east to Russia, Constantinople and the Middle East as looters, traders, colonists and mercenaries. Vikings under Leif Erikson, the heir to Erik the Red, reached North America and set up a short-lived settlement in present-day L'Anse aux Meadows, Newfoundland, Canada. Longer lasting and more established settlements were formed
but it was not used in this sense at the time. In Old Norse and Old English, the word simply meant 'pirate'.
The Norse were also known as , "ashmen", by the Germans, (Norse) by the Gaels and (Danes) by the Anglo-Saxons.
The Gaelic terms (Norwegian Viking or Norwegian), (Danish Viking or Danish) and (foreign Gaelic) were used for the people of Norse descent in Ireland and Scotland, who assimilated into the Gaelic culture
