Unlike the well-established religions of Greece, Rome and Egypt, Celtic myth is more localized, with no universal pantheon. References have been found to over 400 Celtic gods and goddesses, many of whom were only recognized by small cults.
At one time, the Celts were spread throughout Europe as far as Asia minor (modern Turkey). The Celts even occupied Rome for a time, before the rise of the Roman Empire, and although they were eventually brought into the Roman Empire, the Celtic people maintained their own religious practices even after the spread of Christianity.
During the Roman era, Celtic-speaking people inhabited Gaul, a vast area of Europe where France, Belgium, Switzerland and some surrounding areas are now located.
Much of the Celtic population merged with Roman and German cultures, while others survived in the modern Celtic nations around the British isles: Scotland, Ireland, Wales, the Isle of Man, Cornwall and Brittany. Some Celtic populations also remain elsewhere in England and Spain, while others migrated to the Americas, in regions such as Cape Breton in Nova Scotia, Canada.
