Answer:
The answer is VIKINGS.
Step-by-step explanation:
Normans came from Scandinavia (Norway and Denmark), and received their name because when the Vikings attacked France it was very difficult for the French to resist the battles. Hence, the French monarch Charles "The Simple" reached an agreement with Rollo, the Viking king, according to which they were granted a piece of land called Normandy.
The land was granted under certain conditions, one of which was that they had to adopt Christianity and Rollo had to be baptized.
