The inhabitants of Norway, Sweden and Denmark, due to the not very fertile living conditions, also subsisted on robberies in more fertile rich areas, either directly on the coast accessible by their ships ... not only in Europe, but were also known in North Africa, even in North America, where their attempts at settlement failed. They also reached the inland along the rivers. They were known mainly as warriors - robbers. They brought home from the loot only what they could directly use, they got rid of everything else, mostly sold in Mediterranean markets, killed unsold slaves, destroyed others. Their motto "We do not need any burden, what we will not use, we will destroy" was common in the world at that time ... They mostly focused their conquests on a period outside their own work on their farms. although some leaders and their retinue made several years of raids, or were hired as mercenaries. Viking mercenaries, for example, founded the imperial dynasty of medieval Russia. Their culture, dances, songs, myths were harsh and sensitive, as was their nature.
