Also known as: Sur 13, Los Sureños, Sureños Trece
History: The term "Sureños" was first used in the 1970s as a result of a California prison war between the Mexican Mafia
(La EME) and Nuestra Familia (NF). This war resulted in a territorial division between gang members
from northern California (norteños = northerners) who aligned with NF, and those from southern
California (sureños = southerners) aligned with La EME.
Membership/Hierarchy: Sureño gangs share no
common organizational structure; however, they are all subordinate to La EME. Within the prison
system, members of these gangs often unite under direction of La EME.
Location: In addition to prison associations, individual Sureño gang members have
migrated to areas ouside of California and assimilated under the name Sureños. These gang members rarely maintain associations in California, but use the name to signal their
alliance with other Sureño gangs. These gangs use names such as Sur 13, Los Sureños, Sureño Trece,
or other variations.
Gang Identifiers: Sureño identifiers will always include the number "13" and will likely include "Sur" or "Sureño". Gang colors are Blue and White.
