In early medieval texts, the Old Norse word ‘víking’ describes an activity a group of ‘víkingr’ (explorers, merchants, travellers) would carry out as they took to the seas on expeditions. These could include raiding, trading, diplomacy, settlement and intermarriage. And when their violent attacks were recorded, their victims never called them ‘Vikings’. Instead, they were Norse, Swedes or Danes. If written about in a damning way they were ‘pagans’, ‘heathens’ or ‘wolves’.
