Vikings
In England the Viking Age began dramatically on 8 June 793 when Norsemen destroyed the abbey on the island of Lindisfarne. The devastation of Northumbria's Holy Island shocked and alerted the royal courts of Europe to the Viking presence. "Never before has such an atrocity been seen," declared the Northumbrian scholar Alcuin of York. Medieval Christians in Europe were totally unprepared for the Viking incursions and could find no explanation for their arrival and the accompanying suffering they experienced at their hands save the "Wrath of God". More than any other single event, the attack on Lindisfarne demonised perception of the Vikings for the next twelve centuries. Not until the 1890s did scholars outside Scandinavia begin to seriously reassess the achievements of the Vikings, recognizing their artistry, technological skills, and seamanship.
Viking raids in the Rhineland
During this time, the Vikings attacked the Frankish Empire sailing their ships up the big rivers from the North Sea and Atlantic Ocean. Such raids mainly affected areas on the Seine and in modern-day Netherlands and Belgium. Previously, the Vikings had raided England (Lindisfarne, 793) and Ireland (Dublin, 795). In 820, the first major attack by Vikings on the Frankish Empire was recorded, taking place around the mouth of the river Seine, and at the same time other Vikings probably invaded Flanders. In 845, Paris was attacked for the first time with about 700 longships up the Seine. The Parisians bought the raiders off with 7,000 pounds of silver. By 926, thirteen of these payments have been documented in the Frankish Empire. The Elbe estuary and the already fortified city of Hamburg were attacked by Danish warriors in 845.
