It's a widespread idea at this point particularly in modern paganism and popular Western culture that fairies are nature spirits, that is that they are intrinsically bound to our natural world in some way. This idea is often simply stated as fact, implied to have always been true, or even argued as the older or more legitimate belief. In paganism its one aspect of a current trend I'm seeing to homogenize and simplify fairies by defining them as easily as possible, erasing all the nuances and complexity that we find in the actual folklore and beliefs.

I'm not telling anyone what to believe but what does bother me is seeing people claiming that the idea of fairies as spirits of nature is ancient, from a Celtic culture, or in line with folklore. Of course there are examples of beings that we might now classify as fairies from various cultures...that are heavily tied into nature and might fit the description of a nature spirit....

So what then is a nature spirit? I don't think there is any one agreed on definition of this term which is used rather nebulously by different groups. The most basic view of course is that a nature spirit is a spirit of nature, that is a spirit which inhabits or ensouls any natural object or phenomena....

What is a fairy? At its most basic a fairy is an Otherworldly being, although the term is often applied more to such beings from the Celtic cultural milieu than elsewhere. The word is also often used as an adjective, hence 'fairy woman' (bean sidhe), fairy godmother, or fairy hound to describe a more specific type of being that is from Fairy/the Otherworld....Many, many different kinds of Otherworldly beings that are known in folklore and anecdotes under specific names from Brownies to Urisgs, from Bean Sidhe to Each Uisce, would fall under the wider term of fairy.

While many modern pagans and some non-pagan academics may view fairies, in toto, now as nature spirits that is definitely not how they have been understood across history, although as noted some nature spirits do fall into the wider definition of 'fairy'. Rather from its inception in the 12th and 13th centuries the word fairy was applied to beings from the Otherworld (i.e. the world of Fairy) that is beings who were inherently not from the human world. Fairies could pass between the human world and their own world as they chose to, could be seen or be invisible, could - in fact were known to - change their habitations regularly. They were even known to emigrate across oceans with populations or individuals something nature spirits cannot do being bioregion specific. While they may defend natural locations or things like a tree or boulder this is never done because its a tree or boulder but because it belongs to the fairies, or put another way it isn't based on a desire to protect the environment generally but out of territoriality (the same as humans fighting over territory will defend what they perceive to be theirs). As often as we see stories of fairies defending a fairy tree we see stories of them striking a person down for building on a fairy road or fouling a fairy well; its the violation of their possession of a space not the natural world they are angry over.

So, how did this current Westernized view comes about? It was a confluence of different factors rooted in upper and later middle class media and occultism, which explains why the viewpoint is predominantly found today in popculture and modern paganism, but is less common in cultures that still hold older views and understandings of fairies. A concise timeline of the shift in how mainstream Western culture viewed fairies in relation to nature:

-Victorian Era - The Victorian era ran from roughly 1837 to 1901, encompassing the reign of British monarch Queen Victoria. It marked a period that included the end of the Industrial Revolution and many social changes including the growth of the middle class in both the United States and Britain. This period is notable for its romanticism of nature and the natural world, poetic appreciation of paganism and pagan themes, and its radical re-envisioning of fairies in art and literature. Victorian culture, divorced from actual belief in fairies, instead made them the fodder of entertainment infantilizing them, diminishing them, and gentling them in character and appearance, among many other things*.

-Theosophy - beginning in the last quarter of the 19th century Theosophy was the precursor for the 20th century New Age movement and drew on concepts from Gnosticism, Neoplatonism, and Rosicrucianism. It forwarded an understanding of fairies drawn from a blend if contemporary cultural romanticism of nature (see previous point) and the 15th century alchemical classification of fairies as elemental beings. Combining these two concepts resulted in a view of fairies as tied to natural elements and strongly connected to the natural world.

-Edwardians - following the Victorian era we move into the Edwardian, and we see a continuation of the shift in fairies in mainstream culture. JM Barrie's Peter Pan play and book are released during this time and the infamous Cottingley fairy pictures begin at the end of this era; both typify the way that modern popular culture has come to view fairies as small, fairly harmless**, and connected to the natural world in dress, home, and appearance. Immediately following this period we see Cicely Mary Barker's Flower Fairy books emerging which crystalize all of the previous influences into a single form: the fairy as small nature spirit.

-20th Century Pagans - moving into the later 20th century we find these previous influences taken into different corners of paganism and appearing in diverse books. Fairies are defined as spirits of nature, often directly conflated to elementals using the classical alchemical system, and sometimes further seen as guardians of nature and guides to human evolution and right relationship with the earthly world.

This modern view of fairies as nature spirits then is one that has been woven across the last 150 years or so initially coming from groups who did not necessarily believe in fairies but were indulging in a need for entertainment using fairies as the players on the stage, taken from there back into belief, then out again, then back in. This process has largely divorced the fairy-as-nature-spirit from the folkloric fairy, and even perhaps the actual nature spirits from the popular culture ideas of nature-fairies.

Ultimately we can perhaps argue that some fairies are nature spirits, given how loose the definitions of both terms are, but it's an egregious oversimplification to say that all fairies are spirits of nature. We can also say that people who are seeking nature spirits and calling them fairies are getting nature spirits and this undoubtedly adds to the current muddy waters on the subject. But we must be very careful not to generalize out and assume that all fairies are nature spirits because some may be, or even because the ones that a certain author writes about or a certain person connects to are. The bulk of fairylore and modern anecdotal accounts from living cultures with active fairy beliefs show that these Otherworldly beings are not directly tied to the natural world but are travellers who come and go here.

The best way to understand fairies is to look to the living cultures the beliefs come from. Much of what we have as mainstream or popculture beliefs, while not necessarily useless, must be understood in context to really be understood. If you want to understand nature spirits, look to the world around you and work to connect to it; if you want to understand fairies look to generations of gathered knowledge, experience, and be very careful. One of these things is not like the other.
