Vikings in Iberia
The first incursion of the Vikings in Iberia has been characterised as 'probably the most significant episode of the whole period of Viking activity in the South'. It is mentioned in "Annales Bertiniani", and dated August 844, when a group from a plundering expedition entered the Garonne and reached Galicia. Despite storm damage, some proceeded to South-West Spain. This account is consistent with several later, but independent sources in Latin and Arabic. In particular, the late ninth- or early tenth-century "Chronicle of Alfonso III" adds that after plundering a number of coastal villages they were ultimately repulsed in the vicinity of "Farum Brecantium" (i.e. the Tower of Hercules). Ramiro I of Asturias gathered troops in Galicia and Asturia for the counter-attack. After the Asturian victory, the Vikings continued their voyage in direction of Lisbon. While some authors consider that the reliability of this chronicle is open to doubt, others consider that other local chronicles confirm the arrival of the Norsemen.
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.
