The Mongols Motorcycle Club, formed in the 1970s and inspired (in name) by the enormous Mongol empire of Genghis Khan, is believed to have about 70 chapters nationwide, though most of its 500 to 600 or so Latino and Native American members can be found in California, and more often than not, they are former members of Los Angeles-area street gangs. No surprise then that the ATF is one of many law enforcement agencies that consider the Mongols to be the "most violent and dangerous" biker gang currently operating in the United States. Allied with Bandidos, Outlaws and Sons of Silence, the Mongols are rivals with the Hells Angels.
