(Danish: Vikinger; Faroese: Víkingur; Icelandic: Víkingar; Norwegian: Vikinger; Nynorsk: Vikingar; Swedish: Vikingar), from Old Norse víkingr, were Germanic Norse seafarers, speaking the Old Norse language, who raided and traded from their Scandinavian homelands across wide areas of northern and central Europe, as well as European Russia, during the late 8th to late 11th centuries.
The term is also commonly extended in modern English and other vernaculars to the inhabitants of Viking home communities during what has become known as the Viking Age. This period of Norse military, mercantile and demographic expansion constitutes an important element in the early medieval history of Scandinavia, the British Isles, France, Kievan Rus’ and Sicily.
Facilitated by advanced seafaring 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 polities were established in diverse areas of north-western Europe, European Russia, the North Atlantic islands and as far as the north-eastern coast of North America.
