The Celts were a group of tribal societies in Iron Age and Medieval Europe, known for their rich culture and distinct languages. They inhabited regions that are now part of modern-day Ireland, Scotland, Wales, France, and Britain, among others. The Celts are often recognized for their intricate artwork, including metalwork and stone carvings, which reflect their beliefs and social structures. Celtic society was organized into clans, each led by a chieftain. They practiced polytheism, worshipping various deities and nature spirits. The legacy of the Celts continues to influence modern culture, particularly in music, literature, and festivals that celebrate their traditions.
