The North Side Gang, also known as the North Side Mob, was an Irish-Polish-American criminal organization within Chicago during the Prohibition era from the early 1920s to the mid-1930s. It was the principal rival of the South Side Gang, also known as the Chicago Outfit, the crime syndicate of Italian-Americans Johnny Torrio and Al Capone.

History of the North Side Gang

Early history

Like many other Chicago-based Prohibition gangs, the North Side Gang originated from the Market Street Gang, one of many street gangs in Chicago at the turn of the 20th century. The Market Street Gang was made up of pickpockets, sneak thieves and labor sluggers working in the 42nd and 43rd Wards. The gang especially distinguished itself during the newspaper "Circulation Wars" of the early 1910s between the Chicago Examiner and the Chicago Tribune.

It was during the Circulation Wars that future North Side leader Dean O'Banion, then a member of the juvenile satellite Little Hellions, would develop valuable contacts with politicians and journalists. O'Banion and other members of the North Siders would be mentored by safecracker Charlie "The Ox" Reiser. O'Banion was one of the many Market Streeters to become a bootlegger.

Prohibition

With the start of Prohibition, the members of the North Side Gang quickly took control of the existing breweries and distilleries in the North Side of Chicago. This gave them a near monopoly on the local supply of real beer and high quality whiskey; their rivals only had supplies of rotgut liquor and moonshine. Based on the North Clark Street restaurant McGovern's Saloon and Café, the North Side Gang would soon control the working-class neighborhoods of the 42nd and 43rd Wards within months. In addition to bootlegging, the gang continued to burglarize local stores and warehouses and run illegal gambling operations. Unlike the rival Chicago Outfit, however, they refused to traffic in prostitution.

O'Banion strengthened his political protection by assisting his politician friends in committing election fraud. He also ran a publicity campaign in the North Side, with large-scale donations to orphanages and charities as well as food and loans to the poor and unemployed.

The old hostility between Irish and Italian gangs, combined with O'Banion's refusal to sell portions of North Side distilleries to the South Siders, raised tension between the North and South Siders. During several meetings arranged by Torrio, O'Banion would often insult the Italians. O'Banion also secretly hijacked South Side beer shipments and sold them back to their owners. However, the North Side Gang also ran into trouble with other ethnic gangs; in 1921, O'Banion shot Ragen's Colts member Davy "Yiddles" Miller after he insulted a North Sider at a local opera.

Although O'Banion was arrested and charged with burglary in 1922, the North Side Gang enjoyed considerable protection from the Chicago police department. At one point, O'Banion threw a lavish banquet for Chicago politicians and police officials. Attendees included Chief Detective Michael Hughes, Police Lieutenant Charles Evans, County Clerk Robert Sweitzer, public works commissioner Colonel Albert A. Sprague, and a host of both Democratic and Republican politicians. Dubbed the "Balshazzar Feast" by the press, it was later investigated by reform Mayor William E. Dever.

In 1924, Chicago police assisted the North Side Gang in robbing the Sibly Distillery, which had been under federal guard since the beginning of Prohibition. Escorted by Police Lieutenant Michael Grady and four detective sergeants, North Siders looted the distillery in broad daylight, taking 1,750 barrels of bonded whiskey worth approximately $100,000. Although Grady and the other police officers were later indicted for this crime, they were quickly dismissed.

Relations between the North and South Side gangs continued to fester. In early 1924, O'Banion agreed to an alliance with Torrio and Capone that was brokered by Mike Merlo. However, the alliance began to flounder when O'Banion demanded that Angelo Genna pay a $30,000 gambling debt from losses at the co-owned gambling casino The Ship. This demand contravened an agreement allowing Angelo and other gang members to run up debts there. In the interest of maintaining harmony, Torrio persuaded Genna to pay his gambling debt.

However, Torrio himself would lose patience when O'Banion offered to sell him the valuable Sieben Brewery. On May 19, 1924, while Torrio was inspecting the property, O'Banion arranged for the police to raid the place and arrest Torrio. After his release from custody, Torrio acceded to demands from the Genna crime family, allies of Chicago Outfit, to kill O'Banion.
