Religious cults are groups that often deviate from mainstream religious beliefs and practices. They typically have a charismatic leader who claims special knowledge or insight, attracting followers who seek spiritual fulfillment or community. These groups may employ intense recruitment techniques and can sometimes isolate members from their families and society. Cults often promote unique doctrines that differ significantly from traditional religions, which can lead to controversial practices. Some well-known examples include the People's Temple, led by Jim Jones, and the Branch Davidians, led by David Koresh. These groups have been associated with extreme behaviors and tragic events in history.
