The Celtic tribes were a group of ancient peoples who lived in Europe, primarily during the Iron Age and into the Roman period. They were known for their distinct languages, art, and social structures. The tribes inhabited regions that include modern-day Ireland, Scotland, Wales, France, and parts of Central Europe. Celtic society was organized into clans, each led by a chieftain. They practiced agriculture, animal husbandry, and trade, and were skilled in metalwork. The Celts had a rich oral tradition, with stories and legends passed down through generations, contributing to their unique cultural identity.
