When the religion first came to public attention, it was commonly called "Witchcraft". For instance, Gerald Gardner—the man regarded as the "Father of Wicca"—referred to it as the "Craft of the Wise", "witchcraft", and "the witch-cult" during the 1950s. There is no evidence that he ever called it "Wicca", although he did refer to the collective community of Pagan Witches as "the Wica" (with one "c"). As a name for the religion, "Wicca" developed in Britain during the 1960s. It is not known who precisely invented the term "Wicca" in reference to the religion, although one possibility is that it might have been Gardner's rival Charles Cardell, who was referring to it as the "Craft of the Wiccens" by 1958. The first recorded use of the word "Wicca" appears in 1962, and it had been popularised to the extent that several British practitioners founded a newsletter called "The Wiccan" in 1968.
