So much like Christianity there are different denominations of Wicca. Although these different traditions generally believe in the same basics the details are often different. There are many many different traditions of Wicca so below are some of the different traditions (but certainly not all)
-After England removed the witchcraft law in 1950 Gerald Gardner "came out of the broom closet". He rewrote the rituals of the coven he belonged to for accuracy. This Tradition is coven exclusive. You can't really be part of this tradition as a solitary practitioner. In Gardnerian covens they have a degree system in which one learns the craft. The coven has to initiate you into the coven. They do their work skyclad (naked).
Alex Sanders founded this tradition in 1960. It is inspired by Gardnerian Wicca. You still must be in a coven for this tradition. They also work skyclad and have similar rituals to Gardnerian. This tradition places more emphasis on ceremonial magick though.
George Patterson founded this tradition in 1970. Followers of this tradition are also known as the Georgian church. Rituals are inspired from Gardnerian and Alexandrian with some other elements added. In some of these covens members write their own rituals. Some work skyclad and others don't.
Raymond Buckland founded this tradition in 1973. He was a protege of Gardner. Buckland taught the Gardnernian tradition for many years. He saw some flaws in it though so he started his own tradition. This tradition is based on Saxon traditions. Each coven decides if they will work skyclad or robed. Witches of this tradition can be initiated through a coven or through self-study.
This tradition focuses on the goddess with little talk of a god. The goddess is worshipped in her 3 aspects (maiden, mother, and crone). Since the 1970's this tradition has been seen as the feminist movement of the craft. Some covens of this tradition are female only.
Tradition looks to ancient Celtic and Druidic deities and beliefs. There's an emphasis on magickal and healing powers of plants, minerals, gnomes, fairies, and elemental spirits. Some rituals are derived from Gardnerian practice.
Although all Wicca is nature based this type of Wicca really focuses on nature. This type of Wicca tends to draw upon folklore, folk-religion, and folk magick. This tradition focuses a lot on the earth, trees, herbs, plants, and flowers for medicinal purposes and magickal value. They tend to grow their own herbs and have gardens. The deities worshipped varies on the Wiccan but typically Green Wiccans acknowledge the earth mother or a series of nature spirits as their deity. Typically spirits of nature, the dead (human and animal), or the fey are part of this tradition. This is the tradition I am currently interested in.
This is a tradition that is usually not exclusive. Another tradition is typically involved with it. This is a tradition for those people who are fortunate to have Wicca run in the family. I hope my future children will be hereditary Wiccans
This tradition is most common these days especially in solitary practitioners. This tradition is when you take bits and pieces of the various traditions and make your own that works best for you. You can also take elements from other pagan customs like Shamanism or even elements from other religions like Buddhism.
So there we have it, a description of common Wiccan Traditions. Don't forget this is not nearly close to all of them. This is merely an overview of more common ones that are either fundamental to the creation of Wicca or that I find interesting.
The next post will be about the training a Wiccan goes through in a Coven.
Also I didn't get enough questions to do a mytake Q+A but if you'd be interested on a general mytake where I talk about how I found the path and specific things to me in relation to Wicca you should let me know either in the comments or by liking this mytake!
