A "Secret Society" is a group of individuals who come together for a specific purpose, often shrouded in secrecy. Members typically share common interests, beliefs, or goals, and they may engage in exclusive rituals or ceremonies. These societies often have strict membership criteria and may require oaths of secrecy from their members. Historically, secret societies have existed in various cultures and can be associated with political, social, or religious movements. Examples include the Freemasons, the Illuminati, and the Skull and Bones. While some societies focus on philanthropy or personal development, others may pursue more controversial agendas.
