Texas Gangs, Explained: Tango Blast, the Prison Gangs and the State's Tier System

Part of Nationwide Gangs: ← Back to series hub

The biggest Texas gangs were born behind bars. The state's Department of Public Safety (DPS) estimates there are more than 100,000 gang members in Texas, and its four top-tier threats are Tango Blast, the Texas Mexican Mafia, MS-13 and Barrio Azteca.¹ Two of those four started as prison self-protection groups, and the biggest, Tango Blast, exists mainly because inmates wanted protection without joining the older prison gangs.¹

That's the short version. The longer version is a story about prisons that manufacture gangs, a border that turns gangs into cartel subcontractors, and a ranking system that tells you what the state is worried about.

How Texas Ranks Its Gangs

DPS sorts gangs into three tiers, with Tier 1 posing the greatest threat to the state.¹ The ranking isn't just about headcount. The scoring looks at a gang's ties to Mexican cartels, transnational activity, violence, how widespread it is across Texas, its alliances with other gangs, its size, how well it organizes members across the state, juvenile recruitment, threats to police and involvement in sex trafficking.¹

There's a caveat that DPS prints right on its chart: the rankings describe the threat statewide and don't necessarily show the biggest gang problem in any particular region.¹ A Tier 3 gang can be the main problem in one town.

One more caveat. As of October 2026, the most recent statewide assessment DPS posts publicly is the November 2018 edition.¹⁶ Everything below that comes from DPS reflects that report, not a fresh count.

Tier 1: The Big Four

Tango Blast

Estimated size (2018): 22,000–25,000 members.¹

Tango Blast is the largest gang network in Texas, and it isn't really one gang. DPS describes it as a set of cliques that formed as a self-protection group against traditional prison gangs like the Texas Mexican Mafia and the Texas Syndicate.¹ It has no strict commitment rules and a loose structure, which DPS calls a "hybrid" status that allows widespread recruitment and makes it appealing to younger members.¹ The same report says the Tangos have built business relationships with various Mexican cartels.¹

The Texas Mexican Mafia

Estimated size (2018): 4,000–6,000 members.¹

The Texas Mexican Mafia (TMM) formed inside the Texas prison system in 1984, according to DPS, as a way for inmates to protect themselves from the Texas Syndicate.¹ In other words, the protection needed its own protection. DPS reported that law enforcement pressure had slowed TMM's growth and that a younger generation was causing internal strife, but it still expected the gang to stay a significant threat.¹

MS-13

Estimated size (2018): 600–1,000 members.¹

MS-13 is the smallest gang on the Tier 1 list, and it's there for its violence, cartel relationships and recruitment of juveniles, not its size.¹ DPS says MS-13 members once used Texas mainly as a transit route or a place to hide, but that more recent intelligence suggests the gang now uses Houston as a hub of criminal activity.¹

Barrio Azteca

Estimated size (2018): 1,000–2,500 members.¹

Barrio Azteca is the border gang. Its hub is El Paso and Ciudad Juárez, and DPS ties its Tier 1 ranking to its relationships with the Juárez and Sinaloa cartels and its spread into more of Texas.¹ Federal prosecutors describe it as a street and prison gang that began in the late 1980s and grew into a transnational criminal organization allied with La Línea, the enforcement arm of the Juárez cartel.²

The case that made the gang's reach impossible to ignore came on March 13, 2010. Barrio Azteca hit teams in Juárez killed a U.S. Consulate employee, her husband, and the husband of another consulate employee.² The gunmen had initially mistaken them for rival gang members as they left a child's birthday party.³ The Barrio Azteca lieutenant who ordered the killings was sentenced to life in a U.S. federal court in 2014.² Trial evidence showed teams under his command killed up to 800 people between January and August 2010.²

Tier 2: The Long List

The second tier is crowded. In the 2018 report it included:¹

• The Bloods and the Crips, both born in Los Angeles. DPS says Bloods presence in Texas has been documented since the 1980s.¹ Our histories of the Bloods and the Crips cover how they got there.
• The Aryan Brotherhood of Texas, which DPS says puts its racist ideology secondary to its everyday criminal business.¹
• The Texas Syndicate, which formed in the California prison system in the 1960s before moving into Texas prisons and onto Texas streets.¹
• The Latin Kings, the Chicago-born gang that built a "nation". It dropped from Tier 1 to Tier 2 in 2018 after major law enforcement operations in Central Texas.¹
• The Sureños, an umbrella of gangs that pay homage to the California Mexican Mafia.¹
• The Texas Chicano Brotherhood, concentrated in South Texas.¹
• The Gangster Disciples, Chicago-founded and, DPS notes, active around Texas's major military installations.¹
• The Aryan Circle, which DPS describes as having a paramilitary structure.¹
• The Bandidos Outlaw Motorcycle Gang, formed in the 1960s.¹

The Gangster Disciples and the Texas Chicano Brotherhood both moved up to Tier 2 in 2018.¹

The Bikers: Waco and After

On May 17, 2015, members of the rival Bandidos and Cossacks motorcycle clubs met in the parking lot of a Twin Peaks restaurant in Waco. In minutes, nine people were dead and at least 20 were critically injured, making it the deadliest biker shootout in U.S. history.⁴ Police arrested 177 people, and 155 were indicted on identical organized crime charges.⁴

Then the cases fell apart. Only one went to trial, and it ended in a mistrial. In April 2019, the McLennan County district attorney dropped all remaining charges. Nobody was convicted.⁴

DPS's 2018 report says the Waco aftermath and the convictions of the Bandidos' national leadership opened the door for other motorcycle gangs to challenge the club's dominance in Texas.¹ One of those challengers, the Kinfolk Motorcycle Gang, was created in the summer of 2016 and is in a violent feud with the Bandidos. DPS added it as a Tier 3 threat.¹ For the national story of the clubs, see Hells Angels and Bandidos.

The Cartel Connection

The thread that ties almost every Texas gang profile together is Mexico. DPS's scoring explicitly weighs cartel relationships, and the 2018 report links Tango Blast, Barrio Azteca, MS-13, the Texas Syndicate, the Texas Chicano Brotherhood, the Aryan Brotherhood of Texas and the Gangster Disciples to cartels in one way or another.¹ DPS says gangs provide direct support to cartel drug and human smuggling operations into and through Texas, and that cartels use gang members to move weapons and money to Mexico and sometimes to commit violence on both sides of the border.¹ For the bigger picture, see Mexican Cartels on American Soil.

The Newest Case: Houston's YNS

Not every Texas gang is a statewide brand. On October 13, 2026, federal prosecutors in Houston announced charges against 16 alleged members and affiliates of YNS, which they describe as a violent gang in Houston's Greenspoint area.⁵ Six were indicted by a federal grand jury, and 10 face federal criminal complaints. The charges include conspiracy to possess cocaine with intent to distribute, robbery conspiracy and using a firearm during a drug trafficking crime.⁵

According to the allegations, members planned to rob what they believed was a stash house holding 42 kilograms of cocaine, after meeting with a confidential informant.⁵ The case was investigated by FBI Houston and the Houston Police Department, with help from DPS, the ATF and the U.S. Marshals Service.⁵ The defendants are presumed innocent unless convicted, and the cases are ongoing.⁵

Why Texas Prisons Keep Making Gangs

Look at the origin stories and a pattern jumps out. The Texas Syndicate came from California prisons. The Texas Mexican Mafia formed in Texas prisons to protect members from the Texas Syndicate. Tango Blast formed to protect members from both.¹ Each new group was a defensive answer to the last one. DPS also notes a generational shift: younger members are dropping the old "blood in, blood out" rule of lifetime membership in favor of what it calls a free-enterprise approach, as seen in Tango Blast.¹

That's the uncomfortable lesson of Texas gang history: much of it started inside prisons. For more on how American prisons shaped crime outside their walls, see our prisons and punishment series, and for the national map, Street Gangs in American History.

FAQ
