In the smoky backrooms and blood-stained alleys of New York City, two criminal empires clashed and collaborated: the Irish Mob and the Italian Mafia.
This is the story of their rivalry, their uneasy alliances, and the power struggles that defined Hell’s Kitchen in the 20th century. At the heart of this saga is Jimmy Coonan, the Irish-American gangster who dared to challenge the Mafia’s dominance.
Discover the rise and fall of Jimmy Coonan, the mastermind behind The Westies, in our in-depth biography.
The Irish Mob: Grit and Defiance in Hell’s Kitchen
The Irish Mob, rooted in the immigrant struggles of Hell’s Kitchen, was a force of raw, unpolished power. Unlike the structured and ceremonial Italian Mafia, the Irish operated with a fierce, almost reckless intensity. Led by figures like Mickey Spillane and later Jimmy Coonan, the Irish Mob thrived on extortion, loan-sharking, and brutal violence. Their base, Hell’s Kitchen, was a gritty Irish enclave where survival meant outsmarting or outfighting rivals.
The Westies, under Coonan’s leadership, became the most notorious Irish gang, known for their gruesome dismemberment tactics. Their approach was less about tradition and more about sending a message: cross us, and you’ll disappear.
The Italian Mafia: Power and Precision
The Italian Mafia, particularly the Gambino crime family led by Paul Castellano, operated with a different ethos. Structured like a corporation, the Mafia had a hierarchy, codes, and a sprawling network that controlled much of New York’s underworld. Their operations—drug trafficking, racketeering, and contract killings—were executed with precision and discipline, a stark contrast to the Irish Mob’s chaotic energy.
The Mafia’s dominance in New York was unchallenged until the Irish, under Coonan, began carving out their own territory. This set the stage for a clash that would reshape Hell’s Kitchen’s criminal landscape.
Jimmy Coonan’s Gambino Alliance
Rather than wage all-out war, Jimmy Coonan chose a smarter path: alliance. In the 1970s, he struck a deal with Paul Castellano, allowing The Westies to operate under the Gambino family’s protection. In exchange, the Irish handled the Mafia’s “dirty work”—contract killings, debt collection, and street-level enforcement.
This partnership was a game-changer. The Westies gained legitimacy and resources, while the Gambinos outsourced their most violent tasks. But the alliance wasn’t without tension. The Irish Mob’s unpredictability clashed with the Mafia’s rigid structure, creating a fragile balance of power.

Rivalry and Betrayal
Despite their alliance, the Irish Mob and Italian Mafia were never true equals. The Mafia viewed the Irish as useful but subordinate, while Coonan’s ambition fueled resentment. Tensions flared as The Westies expanded into drug trafficking, a domain the Mafia fiercely guarded. Internal betrayals, like Mickey Featherstone’s eventual turn to the FBI, further strained the relationship.
The FBI’s crackdown in the 1980s, fueled by informants like Mickey Featherstone, targeted both groups. Coonan’s 1986 conviction for racketeering and murder marked the end of the Irish Mob’s dominance, while the Mafia faced its own reckoning with high-profile prosecutions.
Legacy of the Irish Mob vs. Italian Mafia
The clash between the Irish Mob and Italian Mafia left an indelible mark on New York’s criminal history. The Westies, though short-lived, proved that a small, scrappy gang could challenge the Mafia’s iron grip. Hell’s Kitchen, once a battleground for these titans, has since gentrified, but its gritty past lingers in the stories of Coonan, Castellano, and their warring empires.
This saga is more than just a crime story—it’s a reflection of the immigrant struggle, the thirst for power, and the cost of ambition. The Irish Mob may have faded, but its defiance lives on in the lore of New York’s underworld.
