Wicca is a religion that can be found in many English-speaking countries, originally founded by the British civil servant Gerald Gardner, probably in the 1940s, although it was first openly revealed in 1954. Since its founding, various related Wiccan traditions have evolved, the original being Gardnerian Wicca, which is the name of the tradition that follows the specific beliefs and practices established by Gerald Gardner.
The history of Wicca is a much debated topic. Gardner claimed that the religion was a survival of matriarchal religions of pre-historic Europe (see Völva), taught to him by a woman named Dorothy Clutterbuck. Many believe he invented it himself, following the thesis of Dr. Margaret Murray and sources such as Aradia: Gospel of the Witches by Charles Godfrey Leland, and the practices of Freemasonry and ceremonial magic; and while Clutterbuck certainly existed, historian Ronald Hutton concluded that she is unlikely to have been involved in Gardner's Craft activities. While the ritual format of Wicca is undeniably styled after late Victorian era occultism, the spiritual content is inspired by older Pagan faiths, with Buddhist and Hindu influences. Whether any historical connection to Pagan religion exists, the aspiration to emulate Pagan religion (as it was understood at the time) certainly does.
The idea of primitive matriarchal religions, deriving ultimately from studies by Johann Jakob Bachofen, was popular in Gardner's day, both among academics (e.g., Erich Neumann, Margaret Murray) and amateurs such as Robert Graves. Later academics (e.g. Carl Jung and Marija Gimbutas) continued research in this area, and later still Joseph Campbell, Ashley Montagu and others highly esteemed Gimbutas's work on the matrifocal cultures of Old Europe. Both matrifocal interpretation of the archaeological record, and the foundations of criticism of such work, continue to be matters of academic debate. Some academics carry on research in this area (consider the 2003 World Congress on Matriarchal Studies). Critics argue that matriarchal societies never actually existed, and are an invention of researchers such as Margaret Murray.
It is commonly understood that Wiccans worship two deities, the Goddess and the God sometimes known as the Horned God. Some traditions such as the Dianic Wiccans mainly worship the Goddess; the God plays either no role, or a diminished role, in Dianism. Many Gardnerian Wiccans do not claim to be duotheistic, but rather, may practice some form of polytheism, often with...
