Chicago – a city known worldwide for its stunning architecture, deep-dish pizza, and vibrant culture. But beneath its gleaming skyscrapers and beautiful lakefront lies a captivating darker history that has fascinated generations: its notorious legacy of crime and gangsters. From the early days of frontier lawlessness to the infamous Prohibition era and beyond, Chicago’s underworld has shaped not just the city’s identity but American popular culture as a whole.

Join us as we journey through the shadowy streets and hidden haunts of Chicago’s most infamous characters and discover why this captivating history continues to intrigue visitors from around the world.

The Seeds of Lawlessness: Chicago’s Early Criminal Days

Chicago’s reputation for lawlessness wasn’t born during Prohibition – it stretches back to the city’s earliest days. As early as the 1840s, while Chicago was transforming from a frontier outpost to a booming metropolis, it was already earning a dubious reputation for horse theft, robberies, and various criminal enterprises.

The city’s strategic location made it a hub for commerce, and where commerce thrived, so did illicit activities. By the mid-19th century, Chicago reportedly hosted more gambling establishments than Philadelphia (a larger city at the time) and had a higher per-capita concentration of gambling venues than New York.

The Great Chicago Fire of 1871 marked a turning point, not just in the city’s architectural development but also in its criminal landscape. The chaotic aftermath of the fire, with widespread looting and a breakdown in social order, created fertile ground for criminal activities to flourish.

The Birth of Chicago’s Underworld Legends

The late 19th and early 20th centuries saw Chicago’s criminal enterprises becoming more organized and its criminals more colorful. One such character was Michael “Mickey” Finn, owner of the Lone Star Saloon. In 1903, Finn was discovered to have been drugging his patrons’ drinks for years, allowing his staff to rob them while unconscious. His nefarious practice gave birth to the term “Mickey Finn” or “slipping a Mickey” – terminology that persists in our cultural lexicon more than a century later.

This period also saw the rise of powerful street gangs, such as Ragen’s Colts, an Irish gang whose influence extended beyond mere criminal activities and into Chicago’s social and political landscape. The gang’s involvement in the Chicago Race Riot of 1919 – which erupted after a Black teenager drowned in Lake Michigan and a white man was arrested for throwing rocks at Black swimmers – demonstrated how deeply criminal organizations had embedded themselves into the city’s fabric. The ensuing violence lasted for days, resulting in numerous deaths, injuries, and extensive property damage.

The Golden Age of Gangsters: Prohibition and the Rise of Organized Crime

While Chicago’s criminal history runs deep, it was the Prohibition era (1920-1933) that truly cemented the city’s reputation as America’s gangster capital. The nationwide ban on alcohol created an unprecedented opportunity for organized crime to flourish, and Chicago’s gangsters seized it with both hands.

Under figures like Johnny Torrio and later Al Capone, the Chicago Outfit transformed from a neighborhood gang into a sophisticated criminal empire that controlled a vast network of speakeasies, gambling dens, and brothels. The enormous profits from bootlegging allowed these organizations to expand their influence, bribing police officers, judges, and politicians to turn a blind eye to their activities.

Walk in Capone’s Footsteps: Our Chicago Crime and Gangster Tour guides you through the neighborhoods where the infamous “Beer Wars” between rival gangs played out, with stops at Holy Name Cathedral where you can still see evidence of a gangland shooting, and past sites where notorious figures like Dean O’Banion and Hymie Weiss conducted their deadly business.

 

The Key Players: Faces of Chicago’s Underworld

Al “Scarface” Capone

No discussion of Chicago’s criminal history would be complete without substantial mention of Alphonse Gabriel Capone. Rising from humble beginnings as a Brooklyn street thug to become the most notorious gangster in American history, Capone’s seven-year reign over Chicago’s underworld has become the stuff of legend.

What made Capone unique wasn’t just his willingness to use violence – though the brutal St. Valentine’s Day Massacre of 1929, where seven members of the rival North Side Gang were gunned down, certainly demonstrated that willingness. It was also his understanding of public relations. Despite his criminal activities, Capone carefully cultivated an image as a benevolent community figure, opening soup kitchens during the Great Depression and presenting himself as a businessman providing services the public demanded.

This carefully managed public persona helped Capone maintain popular support even as law enforcement intensified their efforts to bring him down. Ultimately, it wasn’t murder or bootlegging charges that ended Capone’s career, but tax evasion – a fact that highlights the complex relationship between Chicago’s gangsters and the law.

John Dillinger: Public Enemy Number One

Though not a Chicago native, bank robber John Dillinger’s dramatic final chapter played out on the city’s streets, forever linking him to Chicago’s gangster lore. Known for his daring bank robberies and prison escapes, Dillinger captured the public imagination during the depths of the Great Depression, with some seeing him as a folk hero striking back against the financial institutions many blamed for their economic suffering.

Dillinger’s story came to its dramatic conclusion outside the Biograph Theater in Chicago in 1934, where he was gunned down by FBI agents after being betrayed by the “Lady in Red,” Anna Sage. The theater and the alley where Dillinger fell remain popular stops for those interested in Chicago’s criminal history.

Stand Where History Happened: While our Chicago Crime and Gangster Tour focuses primarily on the North Side and Loop areas, our knowledgeable guides will share fascinating stories about Dillinger and other notorious figures who made their mark on the city’s criminal landscape. You’ll hear tales of “Machine Gun” Jack McGurn at the James Hotel and learn about the Chicago handshake – a deadly greeting in the gangster world.

 

The Supporting Cast

Chicago’s gangland drama featured a colorful cast of characters beyond just Capone and Dillinger:

• Vincenzo “Big Jim” Colosimo: Considered Chicago’s first “Vice Lord,” Colosimo established the South Side Gang that would later evolve into the Chicago Outfit under Torrio and Capone.
• Johnny “The Fox” Torrio: Colosimo’s successor and Capone’s mentor, Torrio was a strategic thinker who laid the groundwork for modern organized crime in America before passing the reins to Capone.
• Frank “The Enforcer” Nitti: Taking over after Capone’s imprisonment, Nitti expanded the Outfit’s operations into labor racketeering and extortion, ensuring the organization’s continued prosperity after Prohibition.
• George “Bugs” Moran: Leader of the North Side Gang and Capone’s chief rival, Moran was the intended target of the St. Valentine’s Day Massacre but arrived late, narrowly escaping death.

The Stage: Infamous Locations in Chicago’s Crime Saga

Chicago’s landscape is dotted with locations that played significant roles in its criminal history, many of which still stand today:

The Biograph Theater

This historic movie house in the Lincoln Park neighborhood remains perhaps the most famous site in Chicago’s gangster geography. It was here, on July 22, 1934, that John Dillinger attended a showing of the film “Manhattan Melodrama” before being gunned down by federal agents in a nearby alley. Today, the theater operates as a live performance venue, but its iconic marquee and façade remain largely unchanged from that fateful night.

St. Valentine’s Day Massacre Site

Though the original building at 2122 North Clark Street has long since been demolished (replaced by a parking lot for a nursing home), this site in Lincoln Park marks one of the bloodiest episodes in gangland history. On February 14, 1929, seven members of George “Bugs” Moran’s North Side Gang were lined up against a wall and executed by men posing as police officers, presumed to be working for Al Capone. The massacre shocked the nation and brought unprecedented law enforcement attention to Capone’s operations.

Holy Name Cathedral

This magnificent cathedral on State Street bears a unique connection to Chicago’s gangland wars – a bullet hole in its cornerstone from a 1926 shootout that killed Hymie Weiss, a member of the North Side Gang. This physical scar on one of the city’s most important religious buildings serves as a permanent reminder of how completely the violence of the gangster era permeated Chicago society.

Green Mill Cocktail Lounge

This Uptown jazz club, opened in 1907, was a favorite hangout of Al Capone, who had a regular table with a clear view of both entrances. The Green Mill also had a series of underground tunnels, allowing for quick escapes during police raids. Today, the Green Mill remains a popular jazz venue with much of its Prohibition-era ambiance preserved, offering visitors a chance to sip cocktails in the same space once frequented by Chicago’s most notorious gangster.

Experience Authentic Locations: The Chicago Crime and Gangster Tour brings you to many historic sites, including the Marina Towers where “The Camel” Murray Humphreys once lived, and locations associated with the notorious Calabrese brothers. You’ll stand at the Clark Street Bridge where Vincent “Schemer” Drucci met his end, and visit the Federal Plaza where some of Chicago’s most significant mob trials took place.

Speakeasies: The Social Centers of Prohibition Chicago

The Prohibition era gave rise to one of Chicago’s most enduring cultural institutions: the speakeasy. These illicit drinking establishments, often hidden behind false fronts or requiring passwords for entry, became important social spaces during the dry years. Unlike the saloons they replaced, speakeasies often welcomed women as patrons, creating more integrated social scenes and challenging traditional gender norms.

Some notable Chicago speakeasies included:

• The Green Mill: Beyond being a Capone hangout, this venue was a premier jazz destination.
• Twin Anchors: Operating under the name “Tante Lee Soft Drinks” during Prohibition, this Old Town establishment claims to be one of Chicago’s oldest bars.
• The Drifter: Located beneath the Green Door Tavern, this modern speakeasy pays homage to its Prohibition-era roots.

Many of these establishments survived the end of Prohibition and continue to operate today, offering visitors a tangible connection to Chicago’s past. The legacy of speakeasies can also be seen in Chicago’s modern craft cocktail culture, which often draws inspiration from Prohibition-era mixology.

Cultural Impact: How Gangsters Shaped Chicago’s Identity

The impact of crime and gangsters on Chicago extends far beyond the historical events themselves. This era profoundly influenced Chicago’s culture in numerous ways:

Music and Entertainment

Chicago’s speakeasies became crucial incubators for jazz music, with musicians like Louis Armstrong and King Oliver finding receptive audiences in these underground venues. The association between jazz and the criminal underworld created a sense of danger and rebellion that helped propel the genre to national prominence.

Literature and Film

Chicago’s crime history has inspired countless works of literature and film, from contemporaneous novels like James T. Farrell’s “Studs Lonigan” trilogy to later works like Nelson Algren’s “The Man with the Golden Arm.” In cinema, gangster films became a distinct genre, with movies like “Scarface” (1932), “The Untouchables” (1987), and “Road to Perdition” (2002) all drawing inspiration from Chicago’s criminal past.

Architecture and Urban Development

The enormous profits generated by bootlegging and other illicit activities during Prohibition found their way into legitimate investments, including some of Chicago’s iconic buildings. The Carbide & Carbon Building, with its dark green and gold façade resembling a champagne bottle, is just one example of how Prohibition-era wealth shaped the city’s skyline.

The Legacy: Chicago’s Ongoing Relationship with its Criminal Past

While the era of Al Capone and the Chicago Outfit’s dominance has long passed, the city continues to grapple with this complex legacy. Today’s Chicago presents two faces to visitors interested in its gangster history: the romanticized version found in tours and museums, and the more sobering reality of how organized crime impacted communities and continues to influence perceptions of the city.

Modern organized crime in Chicago looks very different from its Prohibition-era counterpart, but echoes of that history occasionally resurface in news headlines. Recent developments, like the February 2024 delayed sentencing of reputed mobster Paul Carparelli and the March 2025 judicial decision regarding bribery convictions in the ComEd 4 case, demonstrate that Chicago’s relationship with corruption and organized crime remains an ongoing story.
