How a widow’s name from 1840s Ireland became synonymous with America’s most violent labor conspiracy

The Molly Maguires of Pennsylvania

They called themselves after an Irish widow who fought cruel landlords back home. But in Pennsylvania coal country, the Molly Maguires became something much darker.

Between 1862 and 1876, mine bosses lived in fear of midnight visits from hooded men seeking revenge for workplace injustice. The Ancient Order of Hibernians provided perfect cover for their secret meetings.

Here’s the true story of America’s most notorious mining conspiracy, and where to find the jail-turned-museum that preserves the story.

Irish miners brought old grudges

The Molly Maguires took their name from an Irish widow who fought landlords in 1840s Ireland. When Irish immigrants fled the potato famine to Pennsylvania’s coal region, they brought this tradition of violent payback with them.

Mine owners greeted them with “Irish need not apply” signs and forced them into the most dangerous jobs. Families lived in company housing, shopped at company stores, and often owed money to their bosses at month’s end.

Langdon gets stoned to death

The violence started during the Civil War. On June 14, 1862, pit boss Frank Langdon got into a public fight with young miner John Kehoe at a volunteer rally. That night, someone stoned Langdon to death.

Over the next six years, five more mining officials would die in similar attacks. The war had created perfect conditions for trouble by increasing coal demand while pulling miners away to fight.

Fraternal group hides violent core

The Irish miners needed organization, so they formed the Ancient Order of Hibernians as a legitimate fraternal group. But inside the AOH, a secret inner circle called the Molly Maguires handled the dirty work.

When legal channels failed, the Mollies sent “coffin notices” threatening death to supervisors and strikebreakers. The notices worked because everyone knew the threats were real.

Gowen builds his mining empire

Franklin Gowen saw opportunity in the chaos. As president of the Philadelphia and Reading Railway and Coal Company, he was combining railroad and mining power into one empire.

By 1873, Gowen was determined to crush the growing union movement completely. He had even written a law in 1865 that let companies create their own private police forces. In December 1874, Gowen led other operators in slashing wages by 20 percent.

Spy arrives in coal country

Gowen needed inside information, so he hired the Pinkerton Detective Agency. On October 27, 1873, agent James McParlan arrived in Port Clinton calling himself “James McKenna.”

His orders from Allan Pinkerton were simple: stay until every killer is dead. McParlan earned $12 a week to drink, dance, and talk tough at places like the Sheridan House in Pottsville, slowly winning the trust of local Mollies.

Pay cuts trigger bloody strike

Gowen’s wage cuts pushed the miners over the edge. On January 1, 1875, they went on strike rather than accept the 20 percent reduction. The violence escalated quickly. In March, union leader Edward Coyle was murdered.

Another AOH member was shot by the rival Welsh “Modocs” gang. Mine boss Patrick Vary opened fire on a group of miners, leaving what Gowen later bragged was “a long trail of blood” as they fled.

McParlan watches murders pile up

The spy found himself witnessing exactly what Pinkerton had sent him to document. Gomer James was killed while tending bar. A group of Mollies told McParlan they had murdered mine boss Sanger and his companion.

McParlan had tried to warn Sanger but failed to save him. By late 1875, the constant violence was wearing on the detective: “The very sun looks crimson to me,” he wrote to his boss.

Detective sets his final trap

McParlan knew his cover was wearing thin, so he made one bold play.

He demanded a meeting of all Molly leaders, claiming he needed to defend himself against informer accusations. But he secretly slipped an invitation to Captain Linden along with those sent to the Molly bosses, planning a mass arrest.

When McParlan learned Kehoe planned to kill him, he caught the first train to Philadelphia on March 7, 1876. The Coal & Iron Police had already rounded up over 60 suspected Mollies.

James McKenna was never real

The trials began that spring in Pottsville. On May 6, 1876, a well-dressed stranger walked into the courthouse and took the witness stand. When asked his name, he answered: “James McParlan. I am a detective with Pinkerton’s Detective Force.”

The revelation sent “a deep and universal groan” through the packed courtroom as miners realized their trusted friend had been a spy all along. Gowen himself took over as prosecutor, despite the obvious conflict of interest.

Companies bought their own justice

The trials were rigged from the start. Irish Catholics couldn’t serve on juries, but non-English speaking German Protestants could. Most prosecution witnesses were on the payroll of the same railroad and mining companies trying to destroy the unions.

As one historian later wrote, it was “one of the most astounding surrenders of sovereignty in American history.” Private companies had run the investigation, made the arrests, and prosecuted the cases while the state simply provided the courtroom and gallows.

Seven men hang together

The executions came swiftly. On June 21, 1877, “Black Thursday,” four men dropped through the gallows built inside the jail: Alexander Campbell, Edward Kelly, Michael Doyle, and John Donohue. Three more would follow over the next two years.

Before his execution, one condemned man pressed his dirty hand against his cell wall, declaring: “This handprint will remain as proof of my innocence.” The mark is still visible today.

In 1979, more than a century later, Pennsylvania finally granted John Kehoe a posthumous pardon.
