The Bloods formed in Los Angeles around 1972, with the Piru Street group in Compton at the center of the origin, largely as a defensive alliance among neighborhood gangs that felt pressured by the rapidly growing Crips. They are identified with the color red and, like the Crips, are a loose federation of often-rival "sets" rather than a single organization. Two decades later a separate East Coast formation, the United Blood Nation, coalesced in the New York City jail system at Rikers Island in the early 1990s. This page treats the Bloods as documented social history and as an iconographic record, not as a decoder for identifying people and not as glamorization. Gang tattooing is one narrow strand inside a far larger Black Los Angeles social history that these communities should not be reduced to.

Who are the Bloods?

The Bloods are a loose federation of street gangs that originated in Los Angeles around 1972, associated with the color red and organized into many semi-autonomous neighborhood units called "sets." They formed largely as a defensive response to the growing dominance of the Crips, with the Piru Street group in Compton central to the origin. The Bloods are not a single centralized organization; sets operate independently, share colors and symbols, and have at times been in conflict with one another as well as with Crip sets. A distinct later formation, the United Blood Nation, emerged separately on the U.S. East Coast in the early 1990s.

When and where did the Bloods form?

The Bloods formed in Los Angeles around 1972, with the origin centered on Piru Street in Compton. The documented account is that by late 1972, the Piru group and several other non-Crip neighborhood gangs that felt victimized by Crip pressure held a meeting and agreed to form a new federation, adopting red as their unifying color in deliberate contrast to Crip blue. Some sources trace the Piru group's roots to the late 1960s and treat 1972 as the point of formal alliance. The East Coast United Blood Nation formed later and separately, in 1993, inside the Rikers Island jail complex in New York City.

What do Bloods colors and tattoos mean?

The Bloods are identified with the color red, most visibly the red bandana. Blood-associated tattoos, graffiti, and lettering typically encode set names, neighborhood identifiers, and a vocabulary of symbols and numbers, along with coded letter conventions used to disrespect Crip rivals. United Blood Nation initiation has been associated with a three-dot or "dog paw" mark. These meanings are regional, set-specific, and often deliberately ambiguous; there is no universal decoder, and this page is not a field guide for identifying individuals.

Origins in the social history of South Los Angeles

The Bloods cannot be understood apart from the Crips, and neither can be understood apart from the social history of Black Los Angeles. The same conditions that produced the Crips, the dismantling of the city's Black Power and community organizations after the 1965 Watts uprising, the FBI and LAPD campaigns against the Black Panther Party, and the deindustrialization that stripped stable working-class employment out of South Los Angeles through the late 1960s and 1970s, formed the backdrop for the Bloods as well. The historian Mike Davis in City of Quartz and the gang researcher Alex Alonso both situate the rise of these federations inside that collapse of political and economic infrastructure rather than treating them as freestanding criminal phenomena.

The specific spark for the Bloods, however, was the Crips themselves. As the Crips expanded across South Central and into Compton in the early 1970s, neighborhood gangs that were not Crip-aligned came under sustained pressure. The Piru group, named for Piru Street in Compton, is the documented center of the response. By late 1972, the Piru group and several other independent sets that felt threatened, reported to have included gangs such as the L.A. Brims and the Athens Park Boys among others, met and agreed to band together as a counterweight. They chose red, already associated with Piru identity, as the federation's color, in direct opposition to Crip blue. The name "Blood" drew on a long-standing term of address among Black men, a vernacular word for brother, repurposed as the badge of the new alliance.

This origin matters for an honest treatment. The Bloods are frequently presented in popular media as simply the mirror image of the Crips, two interchangeable rival armies. The documented history is more specific: the Bloods began as the smaller, defensive federation, an alliance of the pressured, and the red-versus-blue rivalry that became an American cultural shorthand grew out of that asymmetry. As with the Crips, the romantic framing that recasts the gang as a political movement and the sensationalist framing that treats it as a spontaneous criminal eruption both miss the documented sequence: young men in segregated, deindustrializing neighborhoods organizing for protection after the institutions that might have channeled that energy had been broken.

The federation of sets

Like the Crips, the Bloods are not one gang. They are a federation of neighborhood-based "sets" that share the color red and a broad rivalry with Crips but operate independently, sometimes with their own colors, customs, and even conflicts with one another. Many sets take their names from streets, neighborhoods, or the Piru lineage; "Piru" itself remains a distinct identity within and alongside the broader Blood federation, and not every Piru set uses the Blood label in the same way. There is no central authority that defines a single national meaning for Blood marks. Each set generates identifiers tied to its own geography and history, which is the structural reason any universal decoder fails.

The United Blood Nation and the East Coast

The Bloods most people encounter on the U.S. East Coast trace to a separate formation. In 1993, at the Rikers Island jail complex in New York City, predominantly African American detainees formed the United Blood Nation as a loose confederation, reported to have organized initially for protection against other established jail groups. The United Blood Nation adopted the Blood identity and red color of the Los Angeles federation but developed as its own organization with its own structure on the East Coast, from which it spread into the surrounding region through the 1990s. The East Coast and West Coast Bloods are therefore linked by name, color, and symbolism rather than by a single continuous chain of command. This jail-system origin also places the United Blood Nation squarely inside the broader American carceral marking history documented elsewhere in the Atlas.

The marking and tattoo record (tiered)

Blood identity has historically been expressed more through color, clothing, hand signs, and graffiti than through tattooing, and where tattoos appear they overwhelmingly encode set and neighborhood identity rather than a fixed symbolic alphabet. The table below describes the claims that circulate about these marks. It is descriptive, not an endorsement of any fixed reading, and it is explicitly not a guide for identifying individuals.

| Mark or convention | Circulated reading | Tier | | --- | --- | --- | | The color red / red bandana | Blood affiliation; the most consistent and widely documented identifier | VERIFIED as the associated color; shade and usage vary by set | | Set name and neighborhood lettering | Identification with a specific set or area | MIXED (the naming convention is documented; any specific decode is local) | | The letter "B" elevated, the letter "C" disrespected or crossed out | Rivalry signaling against Crips in graffiti and lettering | MIXED (documented as a graffiti convention; reading is contextual) | | Three-dot or "dog paw" mark | Associated with United Blood Nation initiation in East Coast reporting | MIXED; an attested association, not a universal Blood mark | | Five-point star, the number five, five-point crown | Alignment claims that vary by region and overlap with other federations | CONTESTED; five-point symbolism is shared across multiple unrelated groups and is not a uniform Blood code | | Generic "gang tattoo" decoder lists online | A fixed national code | FOLKLORE; rejected here |

Hard caution. Any source offering a universal decoder ring for Blood tattoos is unreliable by definition. Meanings are local, set-specific, era-specific, and frequently kept deliberately ambiguous. The five-point star and similar marks in particular are shared across multiple unrelated organizations and carry no single Blood-specific meaning. Law-enforcement "gang identification" guides that flatten this variation have been criticized for producing false positives that fall hardest on young Black men who are not gang-involved.

This record sits inside the broader American carceral tattoo tradition documented elsewhere in the Atlas, and the United Blood Nation's jail-system origin makes that connection direct. The contested-meaning problem here is the same one that governs prison tattooing generally: the marks are real, but the circulated meanings are folklore far more often than they are code.

Significance

The Bloods are significant first as social history. Together with the Crips they are among the most studied examples of what follows the removal of a community's political and economic infrastructure, and the red-versus-blue dynamic became a durable shorthand in American popular culture from the 1980s onward through hip-hop, film, and journalism. That cultural saturation is itself part of why folklore around the marks proliferated and why so many "decoder" lists circulate.

Their iconographic significance is narrower and more contested than popular accounts suggest. The durable element is the color red. The tattoo and lettering systems are real but regional, and they belong to the larger story of how marginalized American communities have used the body, the wall, and the jail yard as documents of belonging and protection.

Cultural context and sensitivity note

This page is social history and an iconographic record. It is not a how-to, not a guide for identifying people as gang members, and not glamorization. Five cautions govern it.

  1. The community is not the gang. Compton, Watts, and the wider Black Los Angeles are a vast social, cultural, and political history. The Bloods are one narrow strand within it. Reducing these neighborhoods to their gangs is itself a distortion, and a historically loaded one.
  2. Meanings are contested. Almost every "meaning" in popular Blood-tattoo lists is regional, era-specific, set-specific, and frequently misread. Meanings are presented here as claims, never as universal facts.
  3. Decoder framing is rejected. This page does not function as a field guide for identifying gang members. The policing practice of reading clothing, marks, or neighborhood as proof of gang membership produces documented false positives and is described here as a framing, not adopted as truth.
  4. Allegations are attributed. Criminal allegations and convictions referenced in connection with these communities are attributed to court records and reported journalism, not asserted as the Atlas's own findings.
  5. Dignity. The people inside this history, including those who were criminalized, are treated as people, not as specimens. The improvised, the coerced, and the violent are described as social history, not as instruction or entertainment.
