The Bandidos Motorcycle Club is a 1%er Motorcycle Club with a worldwide membership. The club was formed in 1966 by Don Chambers in San Leon, Galveston County, Texas, USA. Its slogan is: We are the people our parents warned us about. It is estimated to have 2,400 members in 210 chapters, located in 16 countries. Don Chambers, having served in Vietnam as a Marine, modeled the clubs colors after the scarlet and gold motif of the United States Marine Corps. After Chambers' presidency ended due to his conviction for murder in El Paso, Texas, Ronnie Hodge was elevated to president. Under the watch of Hodge, the Bandidos expanded internationally to become the largest 1%er Motorcycle Club.
The Bandidos, also called the "Bandido Nation", is the fastest-growing outlaw Motorcycle Club in the world with over 90 chapters in the USA, 90 chapters in Europe, and another 17 in Australia and Southeast Asia. In the USA, the club is concentrated in Texas, but extends into Louisiana, Mississippi and twenty other states. The Rock Machine Motorcycle Club in Canada "patched over" to Bandidos in 2000, and there is a chapter in Toronto, Ontario. In recent years the club has also expanded heavily into Austrailia and parts of Europe as well. Additionally, it is looking into setting up shop in Russia and also in Singapore, Malaysia and Thailand. The Bandidos are organized by local chapters, with state and regional officers, as well as a national chapter made up of four regional vice presidents and a national president.
The Bandidos also have a large number of "support clubs." These groups usually wear reverse colors (gold border with red background rather than the Bandidos' red-border–and–gold background). They also commonly wear a "support patch" consisting of a round patch in Bandidos colors on the front upper left of the colors (vest), as worn by the member. Most of these clubs are regional. The Federal Bureau of Investigation as well as the Criminal Intelligence Service Canada have named the Bandidos an Outlaw Motorcycle Club.
