Modern Satanism is a diverse set of ideological beliefs and practices that emerged in the 20th century, primarily associated with the Church of Satan, founded by Anton LaVey in 1966. It emphasizes individualism, self-empowerment, and personal responsibility, often rejecting traditional religious dogmas. Followers typically do not worship a literal devil but use Satan as a symbol of freedom and rebellion against oppressive systems. Another prominent form is Thelema, founded by Aleister Crowley, which incorporates elements of mysticism and personal spiritual exploration. Modern Satanists often engage in rituals and symbolism to express their beliefs, focusing on personal growth and the pursuit of knowledge rather than the worship of supernatural beings.
