The first Mexican gang, the Varrio Viejo Gang, was founded in 1957 by Rodolfo Cadena, a Chicano gangster in Los Angeles. It was made up of 13 prisoners at the Deuel Vocational Institution, who called themselves "La Eme", short for "Mafia" ("Eme" is the Spanish word for the letter M). The first real Mafia organization, however, was the Granados crime family, founded by Rico Granados, who based his organization in Miami, Florida and Havana, Cuba. That organization specialized in pornography, construction, guns, drugs, and whatever Rico could put his hands on; legends said that he buried a body under every house that he built. The Granados were wiped out in 1960, but by this time, many Mexican Mafia families and gangs had formed. They forced the Sureños and Vagos to pay them protection, while they made enemies with Norteños because of their affiliation to the Nuestra Familia gang, which in turn was at war with the Varrio Viejo Gang since the 1960s. The La Eme were later influenced by people such as Montoya Santana, Arturo Guzman Decena, and Martin Madrazo, among others.
