(As late as 1968, the Haymarket events were alive; in that year a group of young radicals in Chicago blew up the monument that had been erected to the memory of the police who died in the explosion. And the trial of eight leaders of the antiwar movement in Chicago around that time evoked, in the press, in meetings, and in literature, the memory of the first "Chicago Eight," on trial for their ideas.)

After Haymarket, class conflict and violence continued, with strikes, lockouts, blacklisting, the use of Pinkerton detectives and police to break strikes with force, and courts to break them by law. During a strike of streetcar conductors on the Third Avenue Line in New York a month after the Haymarket Affair, police charged a crowd of thousands, using their clubs indiscriminately: "The New York Sun reported: "Men with broken scalps were crawling off in all directions…"

Some of the energy of resentment in late 1886 was poured into the electoral campaign for mayor of New York that fall. Trade unions formed an Independent Labor party and nominated for mayor Henry George, the radical economist, whose Progress and Poverty had been read by tens of thousands of workers. George's platform tells something about the conditions of life for workers in New York in the 1880s. It demanded:

that property qualifications be abolished for members of juries.

that Grand Jurors be chosen from the lower-class as well as from the upperclass, which dominated Grand Juries.

that the police not interfere with peaceful meetings.

that the sanitary inspection of buildings be enforced.

that contract labor be abolished in public works.

that there be equal pay for equal work for women.

that the streetcars be owned by the municipal government.

The Democrats nominated an iron manufacturer, Abram Hewitt, and the Republicans nominated Theodore Roosevelt, at a convention presided over by Elihu Root, a corporation lawyer, with the nominating speech given by Chauncey Depew, a railroad director. In a campaign of coercion and bribery, Hewitt was elected with 41 percent of the vote, George came second with 31 percent of the vote, and Roosevelt third with 2 7 percent of the vote. The New York World saw this as a signal:

The deep-voiced protest conveyed in the 67,000 votes for Henry George against the combined power of both political parties, of Wall Street and the business interests, and of the public press should be a warning to the community to heed the demands of Labor so far as they are just and reasonable.…

In other cities in the country too, labor candidates ran, polling 25,000 out of 92,000 votes in Chicago, electing a mayor in Milwaukee, and various local officials in Fort Worth, Texas, Eaton, Ohio, and Leadville, Colorado.

It seemed that the weight of Haymarket had not crushed the labor movement. The year 1886 became known to contemporaries as "the year of the great uprising of labor." From 1881 to 1885, strikes had averaged about 500 each year, involving perhaps 150,000 workers each year. In 1886 there were over 1,400 strikes, involving 500,000 workers. John Commons, in his History of the Labor Movement in the United States, saw in that:

… the signs of a great movement by the class of the unskilled, which had finally risen in rebellion… The movement bore in every way the aspect of a social war. A frenzied hatred of labour for capital was shown in every important strike… Extreme bitterness toward capital manifested itself in all the actions of the Knights of Labor, and wherever the leaders undertook to hold it within bounds, they were generally discarded by their followers.…

Even among southern blacks, where all the military, political, and economic force of the southern states, with the acquiescence of the national government, was concentrated on keeping them docile and working, there were sporadic rebellions. In the cotton fields, blacks were dispersed in their work, but in the sugar fields, work was done in gangs, so there was opportunity for organized action. In 1880, they had struck to get a dollar a day instead of 75 cents, threatening to leave the state. Strikers were arrested and jailed, but they walked the roads along the sugar fields, carrying banners: "A DOLLAR A DAY OR KANSAS." They were arrested again and again for trespassing, and the strike was broken.

By 1886, however, the Knights of Labor was organizing in the sugar fields, in the peak year of the Knights' influence. The black workers, unable to feed and clothe their families on their wages, often paid in store scrip, asked a dollar a day once more. The following year, in the fall, close to ten thousand sugar laborers went on strike, 90 percent of them Negroes and members of the Knights. The militia arrived and gun battles began.

Violence erupted in the town of Thibodaux, which had become a kind of refugee village where hundreds of strikers, evicted from their plantation shacks, gathered, penniless and ragged, carrying their bed clothing and babies. Their refusal to work threatened the entire sugar crop, and martial law was declared in Thibodaux. Henry and George Cox, two Negro brothers, leaders in the Knights of Labor, were arrested, locked up, then taken from their cells, and never heard from again. On the night of November 22, shooting broke out, each side claiming the other was at fault; by noon the next day, thirty Negroes were dead or dying, and hundreds wounded. Two whites were wounded. A Negro newspaper in New Orleans wrote:

… Lame men and blind women shot; children and hoary-headed grandsires ruthlessly swept down! The Negroes offered no resistance; they could not, as the killing was unexpected. Those of them not killed took to the woods, a majority of them finding refuge in this city…

Citizens of the United States killed by a mob directed by a State judge… Laboring men seeking an advance in wages, treated as if they were dogs!..

At such times and upon such occasions, words of condemnation fall like snow-flakes upon molten lead. The blacks should defend their lives, and if needs must die, die with their faces toward their persecutors fighting for their homes, their children and their lawful rights.

Native-born poor whites were not doing well either. In the South, they were tenant farmers rather than landowners. In the southern cities, they were tenants, not homeowners. C. Vann Woodward notes (Origins of the New South) that the city with the highest rate of tenancy in the United States was Birmingham, with 90 percent. And the slums of the southern cities were among the worst, poor whites living like the blacks, on unpaved dirt streets "choked up with garbage, filth and mud," according to a report of one state board of health.

There were eruptions against the convict labor system in the South, in which prisoners were leased in slave labor to corporations, used thus to depress the general level of wages and also to break strikes. In the year 1891, miners of the Tennessee Coal Mine Company were asked to sign an "iron- clad contract": pledging no strikes, agreeing to get paid in scrip, and giving up the right to check the weight of the coal they mined (they were paid by the weight). They refused to sign and were evicted from their houses. Convicts were brought in to replace them.

On the night of October 31, 1891, a thousand armed miners took control of the mine area, set five hundred convicts free, and burned down the stockades in which the convicts were kept. The companies surrendered, agreeing not to use convicts, not to require the "ironclad contract/ and to let the miners check on the weight of the coal they mined.

The following year, there were more such incidents in Tennessee. C. Vann Woodward calls them "insurrections." Miners overpowered guards of the Tennessee Coal and Iron Company, burned the stockades, shipped the convicts to Nashville. Other unions in Tennessee came to their aid. An observer reported back to the Chattanooga Federation of Trades:
