What are some differences between vikings and Celts?

Vikings and Celts were distinct cultures with different origins and societal structures. Vikings, originating from Scandinavia, were known for their seafaring, raiding, and trading during the late 8th to early 11th centuries, while Celts were a diverse group of tribes in Europe, particularly in present-day Ireland, Scotland, and Wales, with a rich tradition in art and storytelling. The Vikings practiced a polytheistic religion and had a hierarchical society centered around chieftains, whereas the Celts had a more tribal and clan-based organization with a strong emphasis on warrior culture and druids as spiritual leaders. Additionally, their languages and art styles differed significantly, reflecting their unique cultural identities.
