Where in Europe did the Vikings attack during the Dark Ages?

Answer 1

Along the coastlines at first, and then up the rivers. The first raid in England was recorded at Lindisfarne in 793. They also raided up the Seine in France, laying siege to Paris at one point. This prompted the King of France to grant Rollo, the Viking leader, the lands west of the Seine and east of Brittany, in exchange for his loyalty to the French Crown. The King of France also owed them protection against other enemies. This is how Normandy was established as a fief of the King of France. This took place in the 10th century, about 100 years before the Norman Conquest of England.

The Vikings also raided Russia, traveling upriver, where the people of that land reportedly asked them to rule over them and protect them. This is where Russia gets its name, as there the Viking raiders were called the Rus.

They raided in North Africa, Spain, Ireland, Scotland, and even settled in the offshore islands, the Orkneys and Shetlands. They colonized Iceland, and the eastern and western shores of Greenland. An expedition to Nova Scotia established a Viking colony at L'Anse Aux Meadowsin the year 1000. This remained there for about a year.

Pretty much everywhere accessible by boat, including the major rivers.
