Wicca is a Neopagan religion and a religious movement found in many different countries. It was first publicised in 1954 by a British civil servant named Gerald Gardner after the British Witchcraft Act was repealed. He claimed that the religion, of which he was an initiate, was a modern survival of an old witch cult, which had existed in secret for hundreds of years, originating in the pre-Christian Paganism of Europe. Wicca is thus sometimes referred to as the Old Religion. The veracity of Gardner's claims cannot be independently proven, and it is thought that Wiccan theology began to be compiled no earlier than the 1920s. Various related Wiccan traditions have since evolved, or been adapted from, the form established by Gardner, which came to be called Gardnerian Wicca. These other traditions of Wicca each have distinctive beliefs, rituals, and practices. Many traditions of Wicca remain secretive and require that members be initiated. There is also a movement of Eclectic or Solitary Wiccans who do not believe that any doctrine or traditional initiation is necessary in order to practice Wicca.
