Who were the Druids priests of?

Druids were the priestly class in ancient Celtic societies, primarily found in regions that are now part of modern-day Ireland, the United Kingdom, and France. They played a significant role in religious, educational, and legal matters within their communities, serving as intermediaries between the gods and the people. Druids were known for their deep connection to nature, as well as their practices in rituals and sacrifices. Their influence waned with the spread of Christianity and the Roman conquest of Celtic territories.
