The Mongols Motorcycle Club, sometimes called the Mongol Nation or Mongol Brotherhood, is a "one-percenter" outlaw motorcycle club and alleged organized crime syndicate. The club is headquartered in southern California and was originally formed in Montebello, California, in 1969. Law enforcement officials estimate there are approximately 1000 to 1500 full-patched members (with the expansion in Australia in 2013). The Mongols main presence is in southern California, but also all over the United States with chapters in 14 states, as well as international chapters in 18 countries.
