Satanism is a group of ideological and philosophical beliefs based on Satan. Contemporary religious practice of Satanism began with the founding of the atheistic Church of Satan in America in 1966, although a few historical precedents exist. Prior to the public practice, Satanism existed primarily as an accusation by various Christian groups toward perceived ideological opponents, rather than a self-identity. Satanism, and the concept of Satan, has also been used by artists and entertainers for symbolic expression.
