What are fairies and Where do they come from?

To understand what they are, we should look at some of those found in Celtic mythology and other Celtic traditions. But, then you would discover that fairies are not just confined in Celtic traditions. Many cultures and civilizations have their own versions of fairies.

There are enough kinds of fairies to confuse anyone, because sometimes writers have associated one fairy with a different kind.

In Celtic religion, there was Celtic deities in Gaul (France and Belgium), Hispania (Spain) and Britannia (Britain) during the Roman occupation of these regions or provinces. But the situation changed when Christianity spread to the west and north. These deities that were worshipped before the conversion to Christianity were reduced to the status of fairies in Celtic mythology and folklore.

So in Ireland the gods in the Tuatha De Danann were degenerated to the roles of fairies (eg. Dagda and Lugh), people living under the dune mound or fabled islands, or even within underwater domains. Similar degeneration occurred with old deities in Wales, Scotland and other surviving pockets of Celtic kingdoms (such as Cornwall, Brittany and island of Man).

These earlier Celtic traditions of fairies, the former Irish or Welsh deities were also not fairies in the usual sense. They looked very much like human, in size and shape, except that they have special magical powers and they seemed eternally young, but they don't have wings. The Dananns or their Welsh counterparts were usually seen as race of fair people. They can die just as mortals can, but their lives could last hundreds or even thousands of years.

The problem is that sometimes, the Christian authors have also turned them into beings serving the Devil, and that the fairies were actually demons. However this view is no longer shared, today.

These medieval fairies are different from the common folklore and fairy tales of today. The Tuatha de Danann is nothing like the brownie, leprechaun and goblin of these later traditions.
