|Vikings is the modern name given to seafaring people primarily from Scandinavia (present-day Denmark, Norway and Sweden), who from the late 8th to the late 11th centuries raided, pirated, traded and settled throughout parts of Europe. They also voyaged as far as the Mediterranean, North Africa, the Middle East, and North America. In some of the countries they raided and settled in, this period is popularly known as the Viking Age, and the term "Viking" also commonly includes the inhabitants of the Scandinavian homelands as a collective whole. The Vikings had a profound impact on the early medieval history of Scandinavia, the British Isles, France, Estonia, and Kievan Rus'.
Expert sailors and navigators aboard their characteristic longships, Vikings established Norse settlements and governments in the British Isles, Ireland, the Faroe Islands, Iceland, Greenland, Normandy, the Baltic coast, and along the Dnieper and Volga trade routes across modern-day Russia, Belarus, and Ukraine, where they were also known as Varangians. The Normans, Norse-Gaels, Rus' people, Faroese and Icelanders emerged from these Norse colonies. The Vikings also voyaged to Constantinople, Iran, and Arabia. 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, profoundly influencing the genetic 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 period they followed the Old Norse religion, but later became Christians. 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 civilization of the Norsemen that emerges from archaeology and historical sources. Interestingly, Viking women enjoyed a wide range of personal liberty, they could divorce their husbands, inherit property and rule, Celtic Queen Boudica is prime example. -From Wikipedia
The Celts (/kɛlts, sɛlts/, see pronunciation of Celt for different usages) or Celtic peoples are a collection of Indo-European peoples in Europe and Anatolia, identified by their use of Celtic languages and other cultural similarities. Historical Celtic groups included the Gauls, Celtiberians, Gallaeci, Galatians, Lepontii, Britons, Gaels, and their offshoots. The relation between ethnicity, language and culture in the Celtic world is unclear and debated; for example over the ways in which the Iron Age people of Britain and Ireland should be called Celts. In current scholarship, 'Celt' primarily refers to 'speakers of Celtic languages' rather than to a single ethnic group.
