The Sons of Ragnarok is an American one-percenter outlaw motorcycle gang active in northern California. In 1948, World War II veterans began riding motorcycles together, and they joined forces with an independent group in Oakland to become one of the largest outlaw biker gangs in the country. The Sons of Ragnarok were predominantly white and had close ties with the Aryan Nations and white supremacist biker gangs, leading to a spike in "white-only" chapters and members and the grolup being considered a terrorist organization.
