Learning Objectives
By the end of this lesson, students will be able to:
- Describe the working conditions inside late-century American factories, mills, and railroads, including hours, wages, accident rates, and the expansion of child labor that accompanied industrial growth.
- Compare the Knights of Labor and the American Federation of Labor as rival models of industrial unionism, accounting for membership rules, programs, leadership, and the consequences of each model.
- Account for the causes, conduct, and outcomes of the four flagship Gilded Age strikes (the Great Railroad Strike of 1877, Haymarket in 1886, Homestead in 1892, and Pullman in 1894), and explain why each strike pulled federal authority further toward the side of capital.
- Use Skill 6.C to construct an argument from the relationships among the lesson primary sources about whether organized labor in the Gilded Age was a defeated movement, a partial success, or both.
- Account for the continuities and shifts in American labor between 1865 and 1898 (Reasoning 3), including the persistence of low wages and dangerous conditions and the shift from broad-membership to craft unionism after Haymarket.
Key Concepts
The story of Gilded Age labor is the story of the human cost that industrial capitalism extracted from the people who actually ran its machines. As prices for many manufactured goods fell after 1870 and the real wages of skilled workers rose modestly, many Americans saw improved standards of living, even as the gap between rich and poor grew wider than at any point in the nineteenth century (KC-6.1.I.C). The picture changed sharply for the workers underneath those headline numbers. Steelworkers in the Pittsburgh mills worked twelve-hour shifts, seven days a week, and rotated between day shift and night shift through a single twenty-four-hour swing every two weeks. Garment workers in New York lofts paid for their own thread and sewing-machine rent out of piece-rate wages that fell during every depression. Railroad brakemen lost fingers, hands, or lives to handheld link-and-pin couplers at a rate that dwarfed every other industrial occupation, and the Interstate Commerce Commission would not require automatic couplers until 1893. The industrial workforce grew, and child labor expanded along with it (KC-6.1.II.B.i): children as young as eight worked as breaker boys in Pennsylvania anthracite mines and as doffers in southern textile mills, and roughly one in six children between ten and fifteen was a wage earner in 1900. The wage settlement that the new factory order produced was, on the whole, less safe, less stable, and less free than the artisanal and farm work it replaced.
Workers responded by organizing. Labor and management clashed over wages and working conditions, with workers organizing local and national unions or directly confronting business leaders (KC-6.1.II.C). Two rival national federations took shape in the 1880s and divided the labor movement for the rest of the century. The first was the Knights of Labor, founded in 1869 in Philadelphia as a secret society of garment cutters and reorganized into a public organization in 1881 under Terence V. Powderly, a Pennsylvania-born machinist. The Knights opened their rolls to skilled and unskilled workers, to women, to African Americans, and to recent immigrants, and they rejected the trade-union assumption that craft membership was the basis for organization. They preached a sweeping program: the eight-hour day, equal pay for women, the abolition of child labor, government ownership of railroads and telegraphs, the replacement of the wage system with cooperative ownership, and an end to convict labor. After a successful 1885 strike against Jay Gould's Wabash Railroad, membership ballooned from roughly 100,000 to roughly 700,000 inside a single year. The Knights were the first major broad-membership national labor organization in American history.
The second federation was the American Federation of Labor, founded in December 1886 under Samuel Gompers, a London-born cigar maker. The AFL took the opposite organizing strategy. It was a federation of skilled-trade unions only, accepting unskilled workers and most women only at the margins, and it pursued what Gompers called pure and simple unionism focused on bread-and-butter wage and hour gains rather than the cooperative or political program of the Knights. Where the Knights asked what was wrong with industrial capitalism, the AFL asked what could be wrung out of it for craft members through the strike, the boycott, and the trade agreement. The AFL accepted industrial capitalism rather than challenging it. By 1900, after the Knights had collapsed, the AFL counted roughly 500,000 members and had become the dominant national labor body for the next forty years.
Four flagship strikes carried the question of labor's place in industrial capitalism into the public square between 1877 and 1894. The first was the Great Railroad Strike of 1877. Pittsburgh, Baltimore, Martinsburg, and St. Louis erupted in July of that year after the Baltimore and Ohio Railroad announced a third wage cut in twelve months. The strike was spontaneous rather than union-organized, and at its peak it stopped most rail traffic between Chicago and the Atlantic coast for nearly two weeks. President Rutherford B. Hayes deployed federal troops, the first peacetime use of the regular army against American workers. More than one hundred strikers and bystanders were killed across multiple cities, and the railroads got their wage cuts. The strike of 1877 set the basic federal pattern that the next three strikes would confirm: when industrial conflict spilled into interstate commerce, the United States Army or the federal courts would intervene on the side of capital.
The second was the Haymarket affair of May 1886. A wave of national strikes for the eight-hour day on May 1, 1886, drew an estimated 350,000 workers off the job in cities across the country. Three days later in Chicago, a labor rally at Haymarket Square called to protest police violence against McCormick Reaper strikers ended when an unidentified bomb thrower killed seven police officers. Eight anarchists were tried for the bombing on the theory that their published rhetoric had incited it; four were hanged, one died by suicide, and the remaining three were eventually pardoned in 1893 by Illinois Governor John Peter Altgeld, who concluded that the trial had been a frame. The Knights of Labor had no organizational connection to the bomb, but the press painted them with the same anarchist brush, and Powderly's cautious public response failed to repair the damage. Membership collapsed from roughly 700,000 in 1886 to roughly 100,000 in 1890. Haymarket is the moment at which the broad-membership model of the Knights gives way to the craft-only model of the AFL.
The third was the Homestead Strike of 1892. The Amalgamated Association of Iron and Steel Workers, the strongest skilled-craft union in the country, struck the Carnegie Steel Homestead Works outside Pittsburgh after manager Henry Clay Frick announced wage cuts and a refusal to renew the union contract while Andrew Carnegie was vacationing in Scotland. Frick locked the workers out, hired three hundred Pinkerton agents, and floated them up the Monongahela River on barges to retake the plant by force. The Pinkertons were beaten back in a daylong battle on July 6 that killed at least nine people. Frick then secured Pennsylvania National Guard troops, broke the strike, and operated the mill with strikebreakers. The Amalgamated Association of Iron and Steel Workers was destroyed inside Carnegie's mills, and the Pittsburgh steel industry would not be unionized again until the New Deal era of the 1930s. Homestead is the moment at which the country's strongest craft union learned that it could not stand against the country's most modern corporation.
The fourth was the Pullman Strike of 1894. George Pullman, the manufacturer of the sleeping cars that ran on every major American railroad, cut wages by roughly twenty-five percent during the 1893 depression while refusing to reduce the rents in his company town outside Chicago. Workers walked out, and Eugene V. Debs's American Railway Union, a new industrial union that organized all railroad workers regardless of craft, voted a sympathy boycott of every train carrying Pullman cars. The boycott shut down rail traffic west of Chicago. Attorney General Richard Olney, a former railroad attorney, secured a federal injunction against the strike under the Sherman Antitrust Act on the theory that the boycott was a conspiracy in restraint of interstate commerce, and President Grover Cleveland sent federal troops to enforce the injunction over the objection of Illinois Governor Altgeld. Debs was jailed for violating the injunction, and the United States Supreme Court unanimously upheld his contempt conviction in In re Debs (1895), giving the federal courts a permanent constitutional weapon against the strike. Pullman is the moment at which the federal injunction became the principal legal device used to break American strikes for the next forty years.
| Year | Strike | Trigger | Federal response | Outcome for labor |
|---|---|---|---|---|
| 1877 | Great Railroad Strike | Third B&O wage cut in twelve months | President Hayes deployed regular army troops | Wage cuts upheld; over one hundred killed; first peacetime federal deployment against workers. |
| 1886 | Haymarket affair | Police violence against eight-hour-day strikers at McCormick | State prosecution of anarchists; no federal action | Knights of Labor publicly identified with anarchism; membership collapsed. |
| 1892 | Homestead Strike | Frick wage cut and lockout at Carnegie Steel | Pennsylvania National Guard restored Frick's plant | Amalgamated Association destroyed; steel non-union for forty years. |
| 1894 | Pullman Strike | Pullman wage cut without rent reduction in company town | Federal injunction under the Sherman Antitrust Act; federal troops | Strike broken; Debs jailed; In re Debs sanctioned the labor injunction. |
A radical alternative survived the defeat of the broad-membership model. The Industrial Workers of the World, founded in Chicago in 1905 and known to its critics as the Wobblies, organized unskilled and immigrant workers in the lumber, mining, and migratory-harvest industries that the AFL had abandoned. The IWW envisioned one big union that would replace the wage system rather than negotiate inside it. Although the IWW falls just outside the bounds of Period 6, it sits on the curriculum as the period's organizational legacy: the unfinished part of the Knights of Labor program that craft unionism would not address. State and federal repression during and after the First World War would dismantle the IWW, but in the early twentieth century it kept the broad-membership tradition alive.
The political and legal context made all of this possible. Late-century courts read the common law of conspiracy, the Sherman Antitrust Act, and the Fourteenth Amendment as protections of contractual freedom that ran in favor of employers, not workers. In re Debs in 1895 turned the labor injunction into a routine instrument; Lochner v. New York in 1905 (just past the period boundary) struck down a New York maximum-hours law for bakers as an unconstitutional interference with the freedom of contract. Working-class political power was real but bounded: immigrant voters delivered urban majorities to political machines that returned services and graft, but they did not deliver federal labor legislation. The eight-hour day for federal employees in 1868, the abolition of the truck-store wage in some states, the federal Erdman Act of 1898 banning yellow-dog contracts on the railroads, and the slow spread of state factory-inspection statutes were the principal legislative gains of the period. Federal recognition of the right to organize would not come until the Wagner Act of 1935. The labor settlement of the Gilded Age was a settlement in capital's favor, and the Progressive Era and the New Deal would be the long political answer to it.
Primary Source Excerpts
Five sources frame the lesson. Together they let students reconstruct the Gilded Age labor argument from the workers' founding documents, from the press coverage of the great strikes, and from the Supreme Court decision that locked the federal injunction into place.
Knights of Labor, Preamble and Platform, 1878
"The recent alarming development and aggression of aggregated wealth, which, unless checked, will inevitably lead to the pauperization and hopeless degradation of the toiling masses, render it imperative, if we desire to enjoy the blessings of life, that a check should be placed upon its power and upon unjust accumulation, and a system adopted which will secure to the laborer the fruits of his toil."
The Reading platform of January 1878 was the founding public statement of the Knights of Labor. Drafted by Uriah Stephens and revised under Powderly, it set out the program by which the Knights would judge every legislative proposal of the next decade: the eight-hour day, the abolition of child and convict labor, equal pay for equal work for women, government ownership of the railroads and the telegraph, the replacement of the wage system with cooperatives, and a graduated income tax. Read alongside the AFL founding documents below, the preamble lets students see the choice the labor movement faced after Haymarket and the program that the AFL chose to abandon.

The press coverage of Haymarket is the proof that newspapers, not the courts, did the political work of breaking the Knights of Labor. The Chicago and New York papers connected the bombing to a broad anarchist conspiracy on the morning after the rally, and the wood engravings that followed turned the eight Haymarket defendants into the public face of organized labor. Powderly's measured public response, which condemned both the bombing and the rush to judgment, satisfied no one. The contrast between the founding platform of 1878 and the press coverage of 1886 is the empirical proof of how quickly public opinion can shift against a movement that the press has reframed as a threat to public order.

The Homestead photographs do for industrial conflict what Mathew Brady did for the Civil War: they put the casualties of a national event on a single visual surface that ordinary people could read. The images of the burned-out Pinkerton barges, of the strikers' wives bringing meals to the riverbank, and of the National Guard tents that occupied the town let students reconstruct the geography and the chronology of one strike with precision. They also let students see what the press coverage left out, including the role of women in the strike committee and the work of the strikebreakers who eventually crossed the picket line.

"The strong arm of the National Government may be put forth to brush away all obstructions to the freedom of interstate commerce or the transportation of the mails. If the emergency arises, the army of the Nation, and all its militia, are at the service of the Nation to compel obedience to its laws."
Justice David Brewer's unanimous opinion in In re Debs upheld the federal contempt conviction of Eugene V. Debs for violating the injunction that broke the Pullman Strike. The opinion rested the federal injunction power on the federal interest in protecting interstate commerce and the federal mails rather than on the Sherman Antitrust Act, but the legal effect was the same: federal judges could enjoin a strike on the application of a federal attorney without a jury, and federal marshals and federal troops could enforce the injunction. In re Debs turned the labor injunction into the dominant legal weapon against American strikes until the Norris-LaGuardia Act of 1932 narrowed it. The case is the legal capstone of the four flagship strikes.

"What does labor want? We want more schoolhouses and less jails; more books and less arsenals; more learning and less vice; more leisure and less greed; more justice and less revenge. We want more of the opportunities to cultivate our better natures."
The AFL convention in Columbus, Ohio, in December 1886 was the founding moment of pure and simple unionism in the United States. Gompers's speeches and the federation's constitution defined organized labor for the next half century: a federation of skilled-craft national unions, autonomous within their own jurisdictions, focused on the strike, the boycott, and the trade agreement, and unwilling to accept the broad-membership coalition that Powderly had built. Read against the Knights of Labor preamble, the Gompers documents are the inflection point. Haymarket had taken the broad-membership model off the table; the AFL constitution put a narrower, harder, and more durable model in its place.

- (Continuity and Change) Compare the Knights of Labor preamble of 1878 with the AFL founding documents of 1886. Identify two continuities and two significant shifts between the two visions. Which set, the continuities or the shifts, did more to determine the trajectory of the American labor movement, and on what grounds?
- (Causation) Trace the causal chain that runs from the Haymarket bombing on May 4, 1886, to the collapse of Knights of Labor membership by 1890. At which step in the chain do you think a different choice by Powderly, by the Chicago press, or by the trial judge would have produced a different outcome, and why?
- (Comparison) Compare the federal response to the Great Railroad Strike of 1877, the Homestead Strike of 1892, and the Pullman Strike of 1894. What pattern emerges, and what does the pattern reveal about the relationship between organized labor and the federal government during the Gilded Age?
- (Continuity and Change) Industrial working conditions in 1898 in many ways resembled those of 1865: long hours, dangerous machinery, and falling real wages during depressions. Identify one specific way the situation of the industrial worker had nonetheless shifted by 1898, and explain why that shift mattered for the workers themselves.
- (Sourcing) Account for how the perspective and the audience of the Knights of Labor preamble, the Haymarket press coverage, the Homestead photographs, the In re Debs opinion, and the AFL founding speeches each shape what the source can and cannot tell us about the question of organized labor's place inside American industrial capitalism.
Classroom Activities
Strike Map and Timeline
Project a wall map of the United States covering the years 1877 through 1894. In pairs, students place the four flagship strikes on the map and the timeline, label each with one cause, one federal response, and one outcome, and color-code them by which side of capital or labor the federal response served. The pairs then write a one-sentence claim that summarizes the pattern they see.
Knights Versus AFL Decision Lab
Distribute the Knights of Labor preamble and the AFL founding speech as paired handouts and a two-column graphic organizer with rows for membership rules, program, leadership, tactics, and likely consequences. Students complete the organizer in pairs, then defend in writing the choice they would have made in 1886 if they had been a Chicago packinghouse worker, a Pittsburgh steel puddler, or a New York garment worker.
Reading the Homestead Photographs
Project the 1892 Homestead photograph series at full size. Students annotate the images in five layers: the geography of the mill on the Monongahela, the strikers' breastworks, the Pinkerton barges, the National Guard tents that followed, and the women and children visible at the margins. Each layer is matched to a key concept code (KC-6.1.II.C, KC-6.1.II.B.i, KC-6.1.I.C). The activity rehearses the visual document type that often appears on the AP exam.
In re Debs in Plain Language
Distribute the operative paragraph of Justice Brewer's opinion. In small groups, students translate the paragraph into plain language a high-school sophomore could read, then identify the specific federal power the opinion creates and the specific labor tactic it disables. Each group ends by predicting one consequence the opinion would have for American labor in the next forty years and supports the prediction with one piece of evidence drawn from the lesson.

AP Practice Questions
- (A) A series of court decisions that ruled the Knights' cooperative ownership program unconstitutional under the Fourteenth Amendment.
- (B) The public association of the Knights with the anarchist bombing at Haymarket Square in May 1886, which broke the federation's reputation even though no Knights leader had any connection to the bomb.
- (C) Terence V. Powderly's open endorsement of the Pullman boycott of 1894 and the resulting federal indictments of Knights officers.
- (D) Samuel Gompers's purchase of Knights of Labor charters and assets at the AFL founding convention in December 1886.
- (E) President Cleveland's executive order banning federal recognition of organizations that admitted women and Black workers as members.
Correct: (B). Knights of Labor membership stood at roughly 700,000 in mid-1886. The Haymarket bombing on May 4 of that year, and the press campaign that followed, identified the Knights with anarchist violence in the public mind and collapsed membership to roughly 100,000 inside three years (KC-6.1.II.C). The other options invert or fabricate the historical record (LO 6.E; Skill 6.C).
- Identify ONE specific way in which industrial working conditions between 1865 and 1898 differed from the work that most Americans had performed before the Civil War.
- Explain ONE specific difference between the Knights of Labor and the American Federation of Labor as models of industrial unionism.
- Explain ONE specific way in which the federal government shaped the outcome of the four flagship Gilded Age strikes (1877, 1886, 1892, or 1894).
Scoring: 1 point for each part. Strong responses to part (a) name a specific shift such as the twelve-hour shift, the rise of piece-rate wages, the expansion of child labor in mines and textile mills, or the high accident rates that handheld railroad couplers produced (KC-6.1.II.B.i, KC-6.1.II.C). Part (b) responses might cite the broad-membership versus craft-only difference, the Knights' cooperative-ownership versus the AFL's pure and simple unionism, or the difference in willingness to accept industrial capitalism as the framework inside which labor would bargain. Part (c) responses might cite President Hayes's deployment of regular army troops in 1877, the state-level prosecution of the Haymarket defendants in 1886-1887, the Pennsylvania National Guard's role at Homestead in 1892, or the federal injunction and federal troops sent against the Pullman strikers in 1894 and the Supreme Court's unanimous decision in In re Debs in 1895.
