The Great Railroad Strike of 1877 heralded a new era of labor conflict in the United States. That year, mired in the stagnant economy that followed the bursting of the railroads’ financial bubble in 1873, rail lines slashed workers’ wages (even, workers complained, as they reaped enormous government subsidies and paid shareholders lucrative stock dividends). Workers struck from Baltimore to St. Louis, shutting down railroad traffic—the nation’s economic lifeblood—across the country.

Panicked business leaders and friendly political officials reacted quickly. When local police forces were unwilling or incapable of suppressing the strikes, governors called out state militias to break the strikes and restore rail service. Many strikers destroyed rail property rather than allow militias to reopen the rails. The protests approached a class war. The governor of Maryland deployed the state’s militia. In Baltimore the militia fired into a crowd of striking workers, killing eleven and wounding many more. Strikes convulsed towns and cities across Pennsylvania. The head of the Pennsylvania Railroad, Thomas Andrew Scott, suggested that, if workers were unhappy with their wages, they should be given “a rifle diet for a few days and see how they like that kind of bread.” Law enforcement in Pittsburgh refused to put down the protests, so the governor called out the state militia, who killed twenty strikers with bayonets and rifle fire. A month of chaos erupted in the city. Strikers set fire to the city, destroying dozens of buildings, over a hundred engines, and over a thousand cars. In Reading, strikers destroyed rail property and an angry crowd bombarded militiamen with rocks and bottles. The militia fired into the crowd, killing ten. Strikers in St. Louis seized rail depots and declared for the eight-hour day and the abolition of child labor. Troops and vigilantes fought their way into the depot, killing eighteen and breaking the strike. Rail lines were shut down all across neighboring Illinois, where coal miners struck in sympathy, tens of thousands gathered to protest under the aegis of the Workingmen’s Party, and twenty protesters were killed in Chicago by special police and militiamen.

Courts, police, and state militias suppressed the strikes, but it was federal troops that finally defeated them. When Pennsylvania militiamen were unable to contain the strikes, federal troops stepped in. When militia in West Virginia refused to break the strike, federal troops broke it. On the orders of the President, American soldiers were deployed all across northern rail lines. Soldiers moved from town to town, suppressing protests and reopening rail lines. Six weeks after it had begun, the strike had been crushed.

Nearly 100 Americans died in “The Great Upheaval.” Workers destroyed nearly $40 million worth of property. The strike galvanized the country. It convinced laborers of the need for institutionalized unions, persuaded businesses of the need for further political influence and government aid, and foretold a half-century of labor conflict in the United States.
