Which Germanic tribe mainly inhabited the Scandinavian Peninsula?

In this case, the Vikings or the Normans are meant. In the 7th-12th centuries, thanks to their art of sailors and warriors, they were able to move in small groups on rowing ships from Norway and Denmark through the North Sea to England and France. As a result, they carried out predatory raids, instilled terror in all the inhabitants of coastal cities and merchants, and also settled in the north of France, giving the name of the province of Normandy. In Russia, these tribes were called Varangians.
