Viking character T-POSE 3D modelVikings were a seafaring people originally from Scandinavia (present-day Denmark, Norway, and Sweden),[3][4][5][6] who from the late 8th to the late 11th centuries raided, pirated, traded, and settled throughout parts of Europe.[7][8][9] They voyaged as far as the Mediterranean, North Africa, the Middle East, Greenland, and Vinland (present-day Newfoundland in Canada, North America). In their countries of origin, and in some of the countries they raided and settled, this period of activity is popularly known as the Viking Age, and the term Viking also commonly includes the inhabitants of the Scandinavian homelands as a whole during the late 8th to the mid-11th centuries. The Vikings had a profound impact on the early medieval history of northern and Eastern Europe, including the political and social development of England (and the English language)[10] and parts of France, and the establishment of Kievan Rus', the ancestor of the later states of Belarus, Russia, and Ukraine.[11][12]

Expert sailors and navigators of their characteristic longships, Vikings established Norse settlements and governments in the British Isles, the Faroe Islands, Iceland, Greenland, Normandy, and the Baltic coast, as well as along the Dnieper and Volga trade routes across Eastern Europe where they were also known as Varangians. The Normans, Norse-Gaels, Rus, Faroese, and Icelanders emerged from these Norse colonies. At one point, a group of Rus Vikings went so far south that, after briefly being bodyguards for the Byzantine emperor, they attacked the Byzantine city of Constantinople.[13] Vikings also voyaged to the Caspian Sea and Arabia.[14][15] They were the first Europeans to reach North America, briefly settling in Newfoundland (Vinland). While spreading Norse culture to foreign lands, they simultaneously brought home slaves, concubines, and foreign cultural influences to Scandinavia, influencing the genetic[16] and historical development of both. During the Viking Age, the Norse homelands were gradually consolidated from smaller kingdoms into three larger kingdoms: Denmark, Norway, and Sweden.

The Vikings spoke Old Norse and made inscriptions in runes. For most of the Viking Age, they followed the Old Norse religion, but became Christians over the 8th–12th centuries. The Vikings had their own laws, art, and architecture. Most Vikings were also farmers, fishermen, craftsmen, and traders. Popular conceptions of the Vikings often strongly differ from the complex, advanced civilisation of the Norsemen 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.[17][18] Varying views of the Vikings—as violent, piratical heathens or as intrepid adventurers—reflect conflicting modern Viking myths that took shape by the early 20th century. Current popular representations are typically based on cultural clichés and stereotypes and are rarely accurate—for example, there is no evidence that they wore horned helmets, a costume element that first appeared in the 19th century
