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.
History of Europe
The Viking Age, a period of migrations of Scandinavian peoples, occurred from the late 8th century to the middle 11th century. The Normans, descendants of the Vikings who settled in Northern France, had a significant impact on many parts of Europe, from the Norman conquest of England to Southern Italy and Sicily. The Rus' people founded Kievan Rus', which evolved into Russia. After 1000 the Crusades were a series of religiously motivated military expeditions originally intended to bring the Levant back under Christian rule. The Crusaders opened trade routes which enabled the merchant republics of Genoa and Venice to become major economic powers. The Reconquista, a related movement, worked to reconquer Iberia for Christendom.
