Answer:
Vikings came from what is now Sweden, Norway, and Denmark. Iceland could also be added to the list if we take into account that the vikings who colonized Greenland and Vinland, in North America, were Icelandic.
Explanation:
A place that was not an point of origin for Vikings was Finland.
Finland had a completely different Finnic culture, and while it is true that later on Swedish Vikings conquered the country, it was not originally a Viking Country.
This is the reason why Finland is not considered an Scandinavian country, it is considered a Nordic country instead.
