On March 17th, 1948 the first Hells Angels Motorcycle Club was founded in Fontana/San Bernardino area in the United States of America. About the same time, other clubs were formed in various parts of the state of California, but none of these clubs were associated with Hells Angels nor with each other. Most of them do not exist today, but the Berdoo charter (San Bernardino) still do.
During the fifties more Hells Angels Charters came into existence. In the beginning the different charters had nothing to do with each other, but after some years they united and a regular criteria of admission was laid down. From having been exclusively a California phenomenon, the club developed internationally in 1961. It happened when the first charter outside California was adopted – strangely enough – as far away as Auckland, New Zealand. During the Sixties Hells Angels spread to the East Coast of the USA and later to the Midwest.
