Wicca

Wicca is a pagan based religion, established in 1954 by Gerald Gardiner, founded on the 1921 writings of Margaret Murray. It is essentially a modern interpretation of witchcraft. Gardiner originally called the religion Witchcraft, and it's followers, the Wica.
Wicca has a strong connection to nature,  colourful rituals, and positive morality laid down in The Wiccan Rede. Major Wiccan themes include love of nature, equality of male and female, appreciation of the ceremonial, a sense of wonder and belief in magic, and appreciation of the symbolism and psychological realities behind the gods and goddesses of antiquity.
Wicca perceives itself as a religion based on the broad themes of ancient pre-Christian paganism, although it is not drawn directly from paganism. For example, Wicca shuns some central practices of old paganism, such as animal sacrifice.
Wicca s organised into autonomous covens, which contain any number of witches of three or more, and are mostly led by a High Priest or Priestess.
