The Gaulish religion was practiced by the ancient Celtic tribes in Gaul, which is now modern-day France and parts of Belgium, Switzerland, and Italy. It was polytheistic, meaning that the Gauls worshipped multiple gods and goddesses, often associated with natural elements, animals, and local landmarks. Rituals included offerings, sacrifices, and festivals to honor these deities. Druids played a significant role in Gaulish religion, serving as priests, teachers, and judges. They were responsible for conducting ceremonies and preserving sacred knowledge. The religion emphasized the importance of nature and the afterlife, with beliefs in reincarnation and the spiritual significance of certain sites, such as groves and rivers.
