Is The Westies a true story? Here's the real history behind the Ronald Reagan-era gangster drama

As big and brash as its New York setting, MGM+ action-drama The Westies stars JK Simmons as an Irish-American gang leader, Eamon Sweeney, managing both his own men and a fraught working relationship with the Mafia. Jonathan Wright looks at the history behind the series

A dimly lit pub interior where four people sit around a worn wooden table. Several pint glasses filled with dark beer, a couple of shot glasses, an ashtray, and a packet of cigarettes are scattered across the tabletop. The group appears relaxed and deep in conversation; one person leans forward with their hands clasped, another rests an arm on the table, while the others sit back slightly. Behind them, framed pictures hang on the wall and a stained‑glass lamp casts warm, amber light over the scene, giving the space a cosy, intimate atmosphere.

In 1975, New York City was synonymous with violence and deprivation. It was also on the verge of bankruptcy. President Gerald Ford was so loathe to extract the city from its fiscal crisis that he inspired a famous headline in the New York Daily News: “Ford to City: Drop Dead.”

But the new decade brought a new sense of optimism and the beginning of a long era of gentrification. Big projects helped to drive the change in mood, such as the construction of the vast Jacob K Javits Convention Center in Hell’s Kitchen, a neighbourhood long associated with working-class Irish-Americans, between 1979 and 1986.

It’s this project that forms the backdrop to The Westies, named for a real-life gang active in the area, and which moves with the percussive energy of Peaky Blinders, not least in the way loud music punctuates the action and, from the moment The Dropkick Murphys’ raucous ‘Dropped on My Head’ kicks in, sets the mood. But how much of what we see on screen is based on the historical record?

Does The Westies tell a true story?

The Westies certainly existed, although there’s not much evidence they adopted this name themselves. Many of the show’s main plot-lines are fictional and major characters have been invented. That said, the series draws heavily on the historical record as it explores life in Manhattan at the beginning of Ronald Reagan’s first presidency.

This was a time when there was moolah to be made in the Big Apple, including for those running rackets and taking backhanders. There’s plenty of evidence to suggest developers paid off mobsters to ensure their projects went ahead without disruption.

Four people stand inside a dimly lit bar with wooden walls and sunlight filtering through blinds. They’re dressed in rugged, casual clothing—jackets, jeans, work boots. One person drinks from a bottle while holding a small cooler; another wears gloves and grips a cane or stick; a third stands with a crowbar at their side; the fourth watches from near the counter. Their stances suggest tension or preparation, giving the scene a cinematic, slightly foreboding atmosphere.

Who were the real-life Westies?

While not as famous as the Italian-American Mafia, the Irish Mob has its own violent history. It’s a story that underpinned, via a 1927 non-fiction book by journalist Herbert Asbury, Martin Scorsese’s 2002 epic Gangs of New York – starring Daniel Day-Lewis as the terrifying Bill the Butcher, a figure based on the real-life William Poole (1821–55).

As for the Westies specifically, the gang emerged in the early 1960s. Their leader from around 1977 is said to have been James Coonan (b1946), who was convicted of racketeering – among other charges – in 1988 and sentenced to 75 years in jail. Today, he resides at Federal Correctional Institution, Schuylkill, a medium-security prison in Pennsylvania.

There’s an underlying truth in JK Simmons’ portrayal of gang leader Eamon Sweeney as a man capable of terrible violence, yet who projects the image of an affable community leader. Mickey Spillane (1933-77), Coonan’s predecessor as the kingpin of Hell’s Kitchen, was a “gentleman gangster” who supposedly gave turkeys to needy families at Thanksgiving.

An older man sits behind a cluttered wooden desk in a dim office with wood‑panelled walls and blinds filtering soft light. He wears a dark shirt, a vest, and a striped tie, leaning back slightly in a cushioned chair. On the desk are a lamp, eyeglasses, a glass tumbler, scattered papers, a pen, and a small decorative object. Behind him, an old‑fashioned radio and several plaques hang on the wall, giving the room a vintage, mid‑century feel.

Did the Westies clash with Italian-American mobsters?

In the series, the Westies have an uneasy truce with the Gambino family, but there’s an undercurrent of suppressed violence in the relationship. The real-life Westies certainly partnered with Italian-American crime families and carried out contract killings on their behalf.

However, there was also tension. In May 1977, Mickey Spillane was murdered, shot five times, likely by Roy DeMeo (1940–83), though this has never been confirmed. It’s widely assumed the killing came about after, as part of manoeuvrings to take over leadership of the Westies, Jimmy Coonan made a deal with Gambino leader Paul Castellano (1915–85).

How much did the construction of the Jacob K Javits Convention Center change Hell's Kitchen?

Today, Manhattan is a place where the purchase price of single-family homes and townhouses averages between $9 and $12.4mn. It’s an island for the rich, but this follows years when money has poured into Manhattan.

Things were very different in December 1979, when detailed plans for the Javits Center were revealed. It was a vast project and its announcement alone led to a surge in real estate prices in the area. However, the build was beset with issues and plans for it to open in 1984 had to be cancelled because of difficulties in manufacturing custom parts. It finally opened on 3 April 1986 and cost many millions more than expected.

In front of the structure, wide cylindrical concrete columns rise from a paved plaza where two people walk past, emphasising the scale and openness of the contemporary architectural design.

Throughout its construction, there were stories of mobsters taking kickbacks and payoffs. Ironically, this can be said to have backfired on the Westies. As in the series, the gang, grown notorious for its violence, attracted the attention of the FBI, which worked with federal and local authorities to bring down the gang and break its hold on Hell's Kitchen.

Did the IRA seek support in New York?

A major subplot in The Westies involves Bridget Walsh (Sarah Bolger), the girlfriend of Sweeney’s sharpest lieutenant in a not-strong field, Jimmy Roarke (Tom Brittney of Granchester fame). When her old flame, Brendan Cahill (Allen Leech), an Irish republican who has taken up arms, shows up asking for a favour, it’s clear she has much to hide. While the specific storyline is fictional, the Irish Republican Army (IRA) often looked to the Irish-American communities of the USA for funding.

Four people stand close together in a softly lit bar, facing one another as if deep in conversation. Warm hanging lights glow above them, and framed pictures line the wall behind. The person on the left wears a light orange short‑sleeved shirt and jeans; next to them, someone in a dark green jacket over a grey shirt listens intently. Beside them, a man in a fitted grey T‑shirt with a brown belt and watch stands with his hands at his sides. On the right, a person in a striped shirt leans slightly forward. Other patrons and ambient bar décor fill the background, giving the scene a casual, intimate atmosphere.

Throughout the Troubles, the Irish Northern Aid Committee (NORAID), supported the republican cause. It still exists today – though on a much smaller scale – and has always maintained it raised money purely for humanitarian relief.
