The Sea Wolves: "The Viking creation of Normandy and its iron Dukes" (The Normans);

During the 9th and 10th centuries Viking raiders from Scandinavia terrorised most of Europe. North Western France suffered increased invasions when by 911 A.D King Charles III "the simple" of France ceded the land from the river Epte to the sea to Rollo's Viking war band. Normandy "land of the North-men", was created. For the next 150 years the iron Dukes of Normandy created one of the most feared and organised Principalities in Medieval Europe.
