LaVey likely began preparations for the formation of his Church of Satan in either 1965 or early 1966, and it was officially founded on Walpurgisnacht 1966. He then declared that 1966 marked Year One of the new Satanic era. It was the first organized church in modern times to be devoted to the figure of Satan, and according to Faxneld and Petersen, the church represented "the first public, highly visible, and long-lasting organisation which propounded a coherent satanic discourse". Its early members were the attendees of LaVey's Magic Circle, although it soon began attracting new recruits. Many of these individuals were sadomasochists or homosexuals, attracted by the LaVeyan openness to different sexual practices. LaVey had painted his house black, with it becoming known as "the Black House", and it was here that weekly rituals were held every Friday night.
