Input: Question: What year did Gardner found his Wicca tradition? Passage:Contemporary Paganism, or Neo-Paganism, is a wide variety of modern religious movements influenced by the various pagan beliefs of pre-modern Europe. The religion of Pagan Witchcraft, or Wicca, was developed in England during the first half of the 20th century and is one of several Pagan religions. The figure at the forefront of Wicca's early development was the English occultist Gerald Gardner (1884–1964), the author of Witchcraft Today (1954) and The Meaning of Witchcraft (1959) and the founder of a tradition known as Gardnerian Wicca. Gardnerian Wicca revolved around the veneration of both a Horned God and a Mother Goddess, the celebration of eight seasonally-based festivals in a Wheel of the Year and the practice of magical rituals in groups known as covens. Gardnerianism was subsequently brought to the U.S. in the early 1960s by an English initiate, Raymond Buckland (1934–), and his then-wife Rosemary, who together founded a coven in Long Island.
