Vikings (Norwegian and Danish: Vikinger; Swedish and Nynorsk: Vikingar; Icelandic: Víkingar), from Old Norse víkingr, were Norse seafarers, speaking the Old Norse language, who raided and traded from their Scandinavian homelands across wide areas of northern, central and eastern Europe, 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, Ireland, France, Kievan Rus' and Sicily.
