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.

The Vikings were originally diverse Scandinavian seafarers from Norway, Sweden, and Denmark (though other nationalities were later involved) whose raids and subsequent settlements significantly impacted the cultures of Europe and were felt as far as the Mediterranean regions c. 790 - c. 1100 CE.
