Wicca is a modern pagan, witchcraft religion. It was developed in England during the first half of the 20th century and it was introduced to the public in 1952 by Gerald Gardner, a retired British civil servant. It draws upon a diverse set of ancient pagan and 20th century hermetic motifs for its theological structure and ritual practice. Wicca is a diverse religion with no central authority or figure defining it. It is divided into various lineages and denominations, referred to as \traditions\, each with its own organisational structure and level of centralisation. Due to its decentralized nature, there is some disagreement over what actually constitutes Wicca. Some traditions, collectively referred to as British Traditional Wicca, strictly follow the initiatory lineage of Gardner and consider the term \Wicca\ to apply only to such lineaged traditions, while other eclectic traditions do not. Wicca is typically duotheistic, worshipping a god and goddess traditionally viewed as a mother goddess and horned god. These two deities are often viewed as facets of a greater pantheistic godhead. However, beliefs range from \hard\ polytheism to even monotheism. Wiccan celebration follows approximately eight seasonally based festivals known as Sabbats. An unattributed statement known as the Wiccan Rede is the traditional basis of Wiccan morality. Wicca involves the ritual practice of magic.
