Vikings were Norse seafarers, mainly speaking the Old Norse language, who during the late 8th to late 11th centuries, raided and traded from their Northern European homelands across wide areas of Europe, and explored westwards to Iceland, Greenland, and Vinland. The term is also commonly extended in modern English and other vernaculars to the inhabitants of Norse home communities during what has become known as the Viking Age. This period of Nordic military, mercantile and demographic expansion constitutes an important element in the early medieval history of Scandinavia, Estonia, the British Isles, France, Kievan Rus' and Sicily. Facilitated by advanced sailing and navigational skills, and characterised by the longship, Viking activities at times also extended into the Mediterranean littoral, North Africa, the Middle East and Central Asia. Following extended phases of (primarily sea- or river-borne) exploration, expansion and settlement, Viking (Norse) communities and governments were established in diverse areas of north-western Europe, Belarus, Ukraine and European Russia, the North Atlantic islands and as far as the north-eastern coast of North America. This period of expansion witnessed the wider dissemination of Norse culture, while simultaneously introducing strong foreign cultural influences into Scandinavia itself, with profound developmental implications in both directions.Popular, modern conceptions of the Vikings-the term frequently applied casually to their modern descendants and the inhabitants of modern Scandinavia-often strongly differ from the complex picture that emerges from archaeology and historical sources. A romanticised picture of Vikings as noble savages began to emerge in the 18th century; this developed and became widely propagated during the 19th-century Viking revival. Perceived views of the Vikings as alternatively violent, piratical heathens or as intrepid adventurers owe much to conflicting varieties of the modern Viking myth that had taken shape by the early 20th century. Current popular representations of the Vikings are typically based on cultural clichés and stereotypes, complicating modern appreciation of the Viking legacy. These representations are not always accurate-for example, there is no evidence that they wore horned helmets.The Vikings were known as Ascomanni ("ashmen") by the Germans for the ash wood of their boats, Dubgail and Finngail ( "dark and fair foreigners") by the Irish, Lochlannach ("lake person") by the Gaels and Dene (Dane) by the Anglo-Saxons. The period from the earliest recorded raids in the 790s until the Norman conquest of England in 1066 is commonly known as the Viking Age of Scandinavian history.Thus the end of the Viking Age for the Scandinavians also marks the start of their relatively brief Middle Ages.Colonization of Iceland by Norwegian Vikings began in the ninth century. During the Viking Age, Scandinavian men and women travelled to many parts of Europe and beyond, in a cultural diaspora that left its traces from Newfoundland to Byzantium.A variety of sources illuminate the culture, activities, and beliefs of the Vikings. Although they were generally a non-literate culture that produced no literary legacy, they had an alphabet and described themselves and their world on runestones. The most important primary sources on the Vikings are contemporary texts from Scandinavia and regions where the Vikings were active.[79]Writing in Latin letters was introduced to Scandinavia with Christianity, so there are few native documentary sources from Scandinavia before the late 11th and early 12th centuries.
