The Aryan Brotherhood is a white supremacist prison gang that originated in the United States during the 1960s. It was formed by white inmates in California prisons as a response to the increasing influence of other racial groups. The gang is known for its violent activities, including drug trafficking and extortion, and has a reputation for brutal enforcement of its rules. Members of the Aryan Brotherhood often use symbols like the number 88, which represents "Heil Hitler," and the swastika. The gang has been involved in various criminal enterprises both inside and outside of prison, and it maintains a strict code of conduct among its members.
