From labor unions to 'super gangs': the evolution of American street life

In short: Before they were symbols of organized crime, early American gangs were often just groups of laborers or migrants seeking identity. From the 1780s to the modern era, these organizations have shifted from local social clubs to sophisticated federations, driven by migration, urban renewal, and systemic exclusion.

The roots of American street gangs are surprisingly diverse. In the 1780s, early groups emerged in New York, including paramilitary groups formed by enslaved people like Smith's Fly Boys. By the early 1800s, immigrant groups—English, Irish, and German—formed gangs in the Five Points neighborhood. Crucially, these early members were often common laborers rather than career criminals. It wasn't until the late 1820s that groups like the Forty Thieves began to focus specifically on criminal activity, eventually establishing links with local politicians. The 20th century saw a geographic and demographic shift. In Chicago, gangs were initially multiethnic but became dominated by Polish and Italian immigrants in the late 1800s, often tied to the Stockyards. In the American West, Los Angeles gangs emerged in the 1920s from 'boy gangs' modeled on Latino 'palomilla' social groups.

Unlike the Midwest, these West Coast gangs were shaped significantly by ethnic segregation and alienation rather than just poverty. By the 1930s and 1940s, these groups began to use graffiti to mark territory and reacted against police authority. Post-WWII dynamics introduced the era of 'super gangs.' In the Northeast, urban renewal and the demolition of low-income housing pushed diverse populations into smaller areas, sparking turf wars. In the Midwest, the Great Migration and the 1919 Chicago race riot created conditions for black youth to form self-protection groups, which evolved into gangs like the Vice Lords by the 1960s. By the 1970s, these groups began federating into massive alliances, such as the Bloods and Crips in Los Angeles or the Folk Nation and People Nation in the Midwest, often coordinating across multiple cities.

The scale of modern gang activity is vast. As of 2011, approximately 1.4 million people in the U.S. were part of gangs, with over 33,000 active groups. While local gangs often emulate national ones for recognition, the most significant dangers currently stem from national street gangs involved in large-scale drug smuggling and international criminal connections.
