"Aryan Nations (AN) is a white nationalist neo-Nazi organization founded in the 1970s by Richard Girnt Butler as an arm of the Christian Identity group Church of Jesus Christ-Christian. As of December 2007 there were two main factions that claimed descent from Butler's group. Aryan Nations has been called a "terrorist threat" by the FBI, and the RAND Corporation has called it the "first truly nationwide terrorist network" in the USA...
...Like many other extreme racist groups, AN has produced many small, transitory subgroups. Rob Mathews formed a group called The Order, which committed a number of violent crimes, including murder. Their mission was to bring about a race war. "
To sum it up, it is a racist extremist group.
