What does MS-13 stand for? 

MS-13

Mara Salvatrucha, commonly known as MS-13, is an international criminal gang that originated in Los Angeles, California, in the 1970s and 1980s. Originally, the gang was set up to protect Salvadoran immigrants from other gangs in the Los Angeles area. Over time, the gang grew into a more traditional criminal organization. MS-13 is defined by its cruelty, and its rivalry with the 18th Street Gang. Many MS-13 members were deported to El Salvador after the close of the Salvadoran Civil War in 1992, or upon being arrested, facilitating the spread of the gang to Central America. The gang is currently active in many parts of the continental United States, Canada, Mexico, and Central America. Most members are Central American, Salvadorans in particular. As an international gang, its history is closely tied to United States–El Salvador relations. In 2018, the gang accounted for less than 1% (10,000) of total gang members in the United States (1.4 million), and a similar share of gang murders. The gang is often referenced by the United States' Republican Party to advocate for anti-immigrant policies.
