The Hells Angels Motorcycle Club (HAMC) is a worldwide one-percenter motorcycle club whose members typically ride Harley-Davidson motorcycles. In the United States and Canada, the Hells Angels are incorporated as the Hells Angels Motorcycle Corporation. Common nicknames for the club are the "H.A.", "Red & White", "HAMC", and "81". With a membership of between 3,000 and 3,600 and 467 charters located in 59 countries, the HAMC is the largest motorcycle club in the world. The Hells Angels originated on March 17, 1948, in Fontana, California, when several small motorcycle clubs agreed to merge. Otto Friedli, a World War II veteran, is credited with starting the club after breaking from the Pissed Off Bastards motorcycle club over a feud with a rival gang. According to the Hells Angels' website, the club’s name was first suggested by an associate of the founders named Arvid Olsen, who had served in the "Hell's Angels" squadron of the Flying Tigers in China during World War II. It is at least clear that the name was inspired by the tradition from World Wars I and II whereby the Americans gave their squadrons fierce, death-defying titles; an example of this lies in one of the three P-40 squadrons of Flying Tigers fielded in Burma and China, which was dubbed "Hell's Angels". In 1930, the Howard Hughes film Hell's Angels showcased extraordinary and dangerous feats of aviation, and it is believed that the World War II groups who used that name based it on the film. According to the Hells Angels' website, they are aware that there is an apostrophe missing in "Hell's", but state that, "...it is you who miss it. We don't". Some of the early history of the HAMC is not clear, and accounts differ. According to Ralph "Sonny" Barger, founder of the Oakland charter, early charters of the club were founded in San Francisco, Gardena, Fontana, Oakland and elsewhere, with the members usually being unaware that there were other clubs. One of the lesser-known clubs existed in North Chino/South Pomona, in the late 1960s. Other sourc
