# Prison gangs in the United States

This short description is INTENTIONALLY "none" &#x2D; please see WP:SDNONE before you consider changing it!
A prison gang is an inmate organization that operates within a prison system, that has a corporate entity, exists into perpetuity, and whose membership is restrictive, mutually exclusive, and often requires a lifetime commitment. Political scientist David Skarbek argues the emergence of prison gangs are due to the dramatic increase in the prison population and inmate's demand for safety. Skarbek observes that in a small, homogeneous environment, people can use social norms to interpret what behavior is acceptable, but a large, heterogeneous setting undermines social norms and acceptable behavior is more difficult to determine. Prison gangs are geographically and racially divided, and about 70% of prison gang members are in California and Texas. Skarbek suggests prison gangs function similar to a community responsibility system. Interactions between strangers are facilitated because you do not have to know an individual's reputation, only a gang's reputation. Some prison gangs are transplanted from the street. In some circumstances, prison gangs "outgrow" the internal world of life inside the penitentiary, and go on to engage in criminal activities on the outside. Gang umbrella organizations like the Folk Nation and People Nation have originated in prisons.

## Prison gangs
### Hispanic

* La Eme or the Mexican Mafia: (Blue) "Eme" is the Spanish name of the letter "M," and it is the 13th letter in the alphabet. The Mexican Mafia is composed mostly of Hispanics, although there rarely are some White members (at least associates). The Mexican Mafia and the Aryan Brotherhood are allies. They work together to control prostitution, drug-running, weapons, and "hits" or murders. Eme was originally formed in 1956 in the Deuel Vocational Institute by Hispanic prisoners from the southern part of that state. It has traditionally been composed of US-born and US-raised Hispanics with "Sureños" gangs of southern California paying tribute to it. During the 1970s and 1980s, Eme in California established the model of leveraging its power in prison to control and profit from criminal activity on the street. The gangs activities fall into two categories: conventional crimes - distributing drugs, robbery, and murder, and illicit market exchange - protecting property, enforcing agreements, and handling disputes. Members of the Mexican Mafia are recognized by a "black hand" tattoo commonly found across their back, chest, leg, or neck. (photo)
* Nuestra Familia: (Red) ("Our family" in Spanish) "N," the 14th letter in the alphabet, along with the Roman numeral "XIV" is the symbol Nuestra Familia is another mostly Hispanic prison gang that is constantly at war with La Eme. It was originally formed by Northern-California- or rural-based Hispanic prisoners with "Norteños" gangs of Northern California paying tribute to it, opposing domination by La Eme which was started by and associated with Los Angeles gang members. Nuestra Familia was first established California's Soledad Prison in the 1960s.
* The Texas Syndicate: A mostly Texas-based street and prison gang that includes mostly Hispanic members and does (albeit rarely) allow non-Hispanic Caucasian members. The Texas Syndicate, more than La Eme or Nuestra Familia, has been associated or allied with Mexican immigrant prisoners, while Eme and Familia tend to be composed of and associate with US-born or raised Hispanics.
* Mexikanemi: Also known as the Texas Mexican Mafia, is a Mexican-American prison and street gang established in the Texas Department of Criminal Justice in 1984. It functions separately from the original California Mexican Mafia, and members consider themselves primarily tied to the area of Aztlán, formerly Mexican territories in the southwestern United States. The group engages in a wide range of illegal activities including drug trafficking, loan sharking, and money laundering.
* Ñetas: a Hispanic (mainly Puerto Rican) gang, founded in Puerto Rico and on the eastern coast of the US. Originally formed in 1970 in the Río Piedras State Penitentiary, Puerto Rico.
* Fresno Bulldogs: Mexican American street and prison gang. Fresno Bulldogs are largely conflicted with other prison gangs and are the biggest Hispanic gang in California unaffiliated with Sureños and Norteños.

### African American

* Most African American prison gangs retain their street gang names and associations. These commonly include Rollin' sets (named after streets, i.e. Rollin' 30s, Rollin' 40s etc.) that can identify with either Blood or Crip affiliations.
* The Black Guerrilla Family represents an exception, as an originally politically based group that has a significant presence in prisons and prison politics. It was founded in 1966 at San Quentin State Prison, California by former Black Panther member George L. Jackson.
* United Blood Nation: an African American street, and prison gang found on the east coast. They are rivals with the Ñetas and have ties with the Black Guerilla Family.

### White

* Aryan Brotherhood: A white prison gang that originated in California's San Quentin Prison amongst White American prisoners in 1964. Their emblem, "the brand", consists of a shamrock and the number 666. Other identifiers include the initials "AB", Swastikas and the sigrune. Perhaps out of their ideology and the necessity of establishing a presence among the more numerous African American and Hispanic gang members, the AB has a particular reputation for ruthlessness and violence. Since the 1990s, in part because of this reputation, the AB has been targeted heavily by state and federal authorities. Many key AB members have been moved to "supermax" control-unit prisons at both the federal and state level or are under federal indictment.
* Nazi Lowriders: A newer white prison gang that emerged after many Aryan Brotherhood members were sent to the Security Housing Unit at Pelican Bay or transferred to federal prisons. NLR is associated with members originally from the Antelope Valley and is known to accept some light-skinned or Caucasian-identified Hispanic members.
* Public Enemy No. 1: A white street and prison gang based in Southern California. They have replaced the NLR in holding the "keys" for the Aryan Brotherhood on the mainline prison population.
* Dirty White Boys: A white prison gang made up of inmates from Texas, and have a heavy presence in the federal system.
* European Kindred: a white supremacist prison gang founded in Oregon that is affiliated with the Aryan Brotherhood (AB) and the Ku Klux Klan (KKK).
* Aryan Circle: The Aryan Circle split from the Aryan Brotherhood to maintain criminal gang status and white supremacist beliefs, and to oppose black and Hispanic prison gangs.
* Dead Man Incorporated (DMI): a predominantly white prison gang founded in the Maryland Correctional System with branches in many other correctional facilities throughout the U.S.
* Pale Kings (PK): a white prison gang that originated in Pittsburgh, Pennsylvania. The Pale Kingz who also identify by the initials "PK" are primarily located within the Pennsylvania state prison system and throughout the county jails of Pennsylvania. Unlike many of the white prison gangs PK does not share the same white supremacy/white supremacist beliefs.
* Aryan Brotherhood of Texas: A white prison, and street gang. Despite the similarity of the name, the Aryan Brotherhood of Texas (ABT) does not have ties with the original Aryan Brotherhood. Founded in Texas in the 1980s, the ABT was created mainly as a criminal enterprise.
* 211 Crew
* Simon City Royals: A predominantly white street and prison gang, established in Chicago during the late 1950s.
* Soldiers of Aryan Culture: A nationwide neo-Nazi prison gang composed exclusively of Caucasian inmates.
* Universal Aryan Brotherhood: A white power prison gang primarily based out of Oklahoma. Despite its name, this gang had no relation to the original Aryan Brotherhood.

## Latent prison management function

Christian Parenti argues in his book Lockdown America that prison gangs serve a convenient function for the prison establishment and officers. They help regulate rogue and rebellious elements within the prison population without intervention from prison authorities.
Parenti sees the repression dished out by gangs on non-affiliated prisoners as a latent function of prison gangs. Thus, gangs are often more-or-less tolerated by prison administrators due to the side-benefits they afford.
