What region did the vikings have the least effect on in the middle ages?

Answer 1

The Vikings had the least effect on Muslims in the Middle Ages.

Answer 2

The Vikings had little effect on areas that were not near water that was navigable from the sea. They went up rivers as far as their longboats would allow, and this was very far, especially in such places as Russia, where the land was flat and the rivers did not have fast currents. But they they had nearly no effect in such places as Austria, Switzerland, and Moravia.

Answer 3

Vikings had least effect on areas that were not accessible by boat. Even in those areas, they did have effect, however, because they were traders who moved goods through much of Europe, and the things they traded found their way further inland from the places where they traded them to places that could only be reached by wagon or pack animal.
