The East Side Longos is a Mexican-American gang that was founded in Long Beach, California during the 1960s. The gang was the largest Sureno gang in the Harbor Area of Long Beach, and it paid homage to the Mexican Mafia. The gang's harsh treatment of Asian immigrants led to the rise of the Tiny Rascal Gang and Asian Boyz, among other Asian gangs, and the Tiny Rascals and Longos became engaged in a deadly feud in the early 1990s after a carload of Tiny Rascals shot and killed a 16-year-old Longo in 1989. The Longos responded by killing several Tiny Rascals, turning the streets into a killing zone. The gang would develop rivalries with the Fresno Bulldogs, the 18th Street Gang, the Nortenos, the Tiny Rascals, the Asian Boyz, Menace of Destruction, the Sons of Samoa, and the Big Circle Gang.
