Gangs and Criminal Networks: Geography, History, and Policy: Territorial Time Travel: Tracing the Geographic Evolution of American Gangs — full transcript

Introduction

Professor Andrea Hagan: And we are back. Welcome to "Let's Talk About Gangs & Criminal Networks." I'm your host, Ms. A. Today, in Episode 5, we're embarking on a journey I call "Territorial Time Travel: The Geographic Evolution of American Gangs." We often think of gangs as a modern problem, but their roots in American soil are deep, tangled, and profoundly shaped by geography. From the crowded tenements of 19th-century New York to the sprawling digital territories of today, the story of American gangs is a story of space and place. Today, we'll analyze how the geographic and social landscapes of the United States have influenced the evolution of gangs. We'll draw on key academic texts, including "Gangs and Social Change" by Martín Sánchez-Jankowski and "History of Street Gangs in the United States" by Howell and Moore. We'll also use a specific case study from a 2007 intelligence report on street gangs in Louisiana to ground our discussion in a real-world example.

Part 1: The Birth of Territoriality - 19th Century Urban America

Professor Andrea Hagan: Our story begins in the rapidly industrializing cities of the 19th century. Waves of European immigrants, particularly the Irish, settled in densely packed, impoverished neighborhoods. As Howell and Moore note, these early gangs, like the infamous Five Points in New York City, were born from "slum conditions and the accompanying crime problems." Their territory was their world. It was a "defensive localism," as described by Adamson, where the gang served as the "basic unit of social life among the young males." These weren't just criminal enterprises; they were social hubs, often indistinguishable from local fire companies or political clubs. Their territory was a source of identity and a buffer against a hostile new world. Sánchez-Jankowski argues that this early gang formation was a rational response to structural conditions. For marginalized immigrant youth, the gang provided "camaraderie, entertainment, and goods to consume." It wasn't a sign of individual pathology, but a collective adaptation to poverty and discrimination.

Part 2: Expanding Scales - Prohibition and Organized Crime

Professor Andrea Hagan: The 20th century brought new geographic dynamics. Prohibition, enacted in 1920, was a game-changer. Suddenly, the localized territories of street gangs were insufficient. The demand for illegal alcohol created a national market, and with it, the rise of organized crime syndicates. This era saw a dramatic expansion in the geographic scale of criminal networks. Figures like Al Capone, who got his start in the Five Points Gang of New York, built empires that spanned cities and states. As Sánchez-Jankowski points out, this period marked a shift. Gangs became more involved in the "production and retail illicit drug economy," a precursor to the drug-fueled gang violence of later decades. The key geographic concept here is the expansion of market territory. The need to control supply chains, from production to distribution, forced criminal organizations to think beyond the neighborhood. This set the stage for the transnational networks we see today.

Part 3: Segregation and Resistance - The Civil Rights Era and the Rise of Modern Street Gangs

Professor Andrea Hagan: The mid-20th century saw another massive demographic shift: the Great Migration of African Americans from the rural South to northern and western cities. This internal migration, as Howell and Moore detail, led to the formation of new, racially segregated ghettos. In cities like Chicago and Los Angeles, black youth faced intense hostility from white gangs and a discriminatory justice system. Gangs like the Black P-Stone Nation and the Gangster Disciples in Chicago, as well as the Crips and Bloods in Los Angeles, initially formed as a means of self-protection. They were a response to "racial intimidation, school and residential segregation, [and] extreme marginalization." Here, geography is explicitly about spatial segregation and resistance. The "defensive localism" of the 19th century was reborn, but now infused with the politics of race and the struggle for civil rights. The very boundaries of the ghetto, meant to contain and control, became the territories these new gangs claimed and defended.

Part 4: Geographic Concentration and Violence - The Crack Epidemic

Professor Andrea Hagan: The 1980s brought the crack cocaine epidemic, and with it, an explosion of gang-related violence. This period is a stark example of how a new market can radically reshape the geography of crime. Sánchez-Jankowski describes this as a time of "drug deregulation," where the decline of the Italian Mafia's monopoly opened up opportunities for street gangs to enter the retail drug trade. The result was a "combination of contracting market opportunities in the production sector... and the expanding market opportunities in... the illicit drug economy." Geographically, this led to intense concentration and competition. Gang territories became valuable real estate for drug sales. The violence was not random; it was a tool to control these markets. As Sánchez-Jankowski notes, in an underground economy with no legal recourse, "those who possess the most physical power and are willing to use it are the most successful." This is why the crack era is synonymous with a dramatic increase in gang-related homicides.

Part 5: From Local to Global - Contemporary Transnational Networks

Professor Andrea Hagan: This brings us to the contemporary era, where gangs have gone global. The rise of transnational gangs like MS-13 is a direct consequence of U.S. deportation policies in the 1990s. As Howell and Moore explain, gang members deported to Central America "effectively imported Los Angeles-style gang culture to the post-conflict societies of El Salvador, Guatemala and Honduras." This created a "revolving door" of migration and criminal activity. These gangs now operate across national borders, involved in drug trafficking, human smuggling, and other international crimes. Their territory is no longer just a neighborhood; it's a network of "cliques" spanning the hemisphere. This represents the ultimate evolution of gang geography, spanning from the local street corner to the global network.

Case Study: Louisiana - A Microcosm of Gang Geography

Professor Andrea Hagan: Now, let's bring these themes to a specific location: Louisiana. A 2007 intelligence report from the Louisiana State Analytical and Fusion Exchange provides a fascinating snapshot of gang activity in the state. The report identifies two main types of gangs: turf gangs and transient gangs. This immediately highlights the geographic dimension. The turf gangs, like the "1100 Boys" and "900 Boys" in Iberia Parish, are defined by their specific, block-level territories. Their conflicts are classic turf wars, rooted in neighborhood identity and control of local drug markets, primarily crack and powdered cocaine. This mirrors the historical patterns we've discussed, from the 19th-century immigrant gangs to the crack-era street gangs. The report also notes the presence of nationally affiliated gangs, such as the Bloods and Crips, in cities like Alexandria and Shreveport.

Professor Andrea Hagan: This shows how national gang cultures have diffused and adapted to local conditions. The "Lakeview Boyz" in Shreveport, for example, are identified as a branch of the Rolling 60's Crips, a clear link to the gang's origins in Los Angeles. Finally, the report touches on the emergence of transnational gangs like MS-13 in Louisiana, noting a "significant increase in Hispanic workers" after Hurricane Katrina. While the report states that, at the time, there were "no known criminal activities or violent crimes connected to these members," it highlights the potential for these networks to establish a foothold in the future. This is a perfect example of how migration patterns, driven by economic opportunity (in this case, post-disaster rebuilding), can create the conditions for the emergence of new gang geographies. The Louisiana case study illustrates, in microcosm, the multiple layers of gang geography operating simultaneously: the hyper-local turf gang, the nationally affiliated set, and the emerging transnational network.

Conclusion: There is Nothing New Under the Sun

Professor Andrea Hagan: As we've seen, the geographic evolution of American gangs is a story of adaptation. From the defensive territoriality of immigrant gangs to the market-driven expansion of organized crime, from the segregated spaces of resistance to the global networks of today, gangs have consistently responded to the changing social, economic, and political landscapes of the United States. Sánchez-Jankowski puts it best when he argues that gangs "respond to rather than create significant social changes." The patterns we see across time and space are not coincidental. They are the product of enduring structural forces: poverty, discrimination, marginalization, and the allure of the underground economy. The geography of gangs is not just about maps and territories. It's about power, identity, and survival. It's about how the very spaces we inhabit shape our lives, our choices, and our destinies. That's all the time we have for today.
