18th Street, also known as “Barrio 18,” is a notorious and violent gang that originated in the Rampart district in central Los Angeles. The gang was formed in the 1960s after Clanton 14, one of the oldest Hispanic gangs in the city, refused to be more inclusive and accept members who were not Mexican. In response, younger Mexican-Americans created 18th Street and began recruiting members from different nationalities, making it one of the first multiracial gangs.
Today, 18th Street operates as loosely organized cells or “cliques,” with each cell reporting to a leader who oversees activities in a specific region. The gang gained prominence during the 1992 LA riots when rival gangs united against the LAPD following the acquittal of four white officers in the Rodney King case.
In recent years, 18th Street has become a transnational criminal organization, engaging in drug trafficking, human smuggling, and violence, including murder. The gang has established a criminal empire built on extortion, drug trade, and intimidation through violence. In a surprising turn of events, 18th Street and MS-13, former rivals, joined forces to form a “super gang” focused on profit-making ventures like drug trafficking and underground casinos.
To move up in the gang’s hierarchy, members are required to commit heinous crimes that advance the gang’s interests. Targets include rival gangs, members who violate rules, and individuals suspected of cooperating with law enforcement. The gang also extorts street vendors and homeless individuals, demanding “rent” for residing in areas under their control.
In a tragic incident in 2013, a member of 18th Street was sentenced to life in prison for attempting to kill a street vendor who failed to make a payment. The vendor survived, but a 23-day-old infant nearby was killed in the crossfire. With over 50,000 members, 18th Street is one of the largest criminal organizations globally and was designated a Foreign Terrorist Organization and Specially Designated Global Terrorist in September 2025.
