The Mexican Mafia, also known as La Eme, is a highly organized criminal group that originated in the California prison system during the late 1950s. It was formed by Mexican-American inmates to protect themselves and gain power within the prison environment. Over time, the gang expanded its influence beyond prisons, engaging in various criminal activities, including drug trafficking, extortion, and murder. The Mexican Mafia is known for its strict code of conduct and loyalty among members. It often collaborates with other gangs, such as the Norteños and Surenos, to maintain control over territories and criminal enterprises. Law enforcement agencies continue to combat the group's activities, which pose significant challenges to public safety.
