context_page_description: Viking expansion is the process by which Norse explorers, traders and warriors, the latter known in modern scholarship as Vikings, sailed most of the North Atlantic, reaching south to North Africa and east to Russia, Constantinople and the Middle East as looters, traders, colonists and mercenaries. Vikings under Leif Erikson, the heir to Erik the Red, reached North America and set up a short-lived settlement in present-day L'Anse aux Meadows, Newfoundland, Canada. Longer lasting and more established settlements were formed in Greenland, Iceland, the Faroe Islands, Great Britain, Ireland and Normandy.
  It is debated whether the term Viking represents all Norse settlers or just those who raided.
context_section_description: Compared with the rest of Western Europe, the Iberian Peninsula seems to have been little affected by Viking activity, either in the Christian north or the Muslim south. In some of their raids on Iberia, the Vikings were crushed either by the Kingdom of Asturias or the Emirate armies.
  Our knowledge of Vikings in Iberia is mainly based on written accounts, many of which are much later than the events they purport to describe, and often also ambiguous about the origins or ethnicity of the raiders they mention. A little possible archaeological evidence has come to light, but research in this area is ongoing. Viking activity in the Iberian peninsula seems to have begun around the mid-ninth century as an extension of their raids on and establishment of bases in Frankia in the earlier ninth century, but although Vikings may have over-wintered there, there is as yet no evidence for trading or settlement.
  The most prominent and probably most significant event was a raid in 844, when Vikings entered the Garonne and attacked Galicia and Asturias. When the Vikings attacked A Coruña they were met by the army of King Ramiro I and were heavily defeated. Many of the Vikings' casualties were caused by the Galicians' ballistas – powerful torsion-powered projectile weapons that looked rather like giant crossbows. 70 of the Vikings' longships were captured on the beach and burned.
  They then proceeded south, raiding Lisbon and Seville. This Viking raid on Seville seems to have constituted a significant attack.
  859–861 saw another spate of Viking raids, apparently by a single group. Despite some elaborate tales in late sources, little is known for sure about these attacks. After unsuccessful raids on both northern Iberia and Al-Andalus, the Vikings seem also to have raided other Mediterranean targets – possibly but not certainly including Italy, Alexandria, and Constantinople−and perhaps over-wintering in Francia.
  Evidence for Viking activity in Iberia vanishes after the 860s, until the 960s–70s, when a range of sources including Dudo of Saint-Quentin, Ibn Ḥayyān, and Ibn Idhārī, along with a number of charters from Christian Iberia, while individually unreliable, together afford convincing evidence for Viking raids on Iberia in the 960s and 970s.
  Tenth- or eleventh-century fragments of mouse bone found in Madeira, along with mitocondrial DNA of Madeiran mice, suggests that Vikings also came to Madeira (bringing mice with them), long before the island was colonised by Portugal.
  Quite extensive evidence for minor Viking raids in Iberia continues for the early eleventh century in later narratives (including some Icelandic sagas) and in northern Iberian charters. As the Viking Age drew to a close, Scandinavians and Normans continued to have opportunities to visit and raid Iberia while on their way to the Holy Land for pilgrimage or crusade, or in connection with Norman conquests in the Mediterranean. Key examples in the saga literature are Sigurðr Jórsalafari (king of Norway 1103–1130) and Røgnvaldr kali Kolsson (d. 1158).
