If someone studies about flags, they will notice that the flags in many regions are similar and have similar territories such as Northern Europe or Scandinavia with the same flag but only different colors because these countries have races from the Viking language in the past when they founded the country and accepted Christianity. These countries had the same national and similar flag.

Scandinavia is a group of countries in northern Europe that includes Denmark, Norway and Sweden. The term is most often used linguistically, to mean places that speak Scandinavian languages (also called the North Germanic languages). Norway, Sweden and some of Finland are on this peninsula.
