In the spring of 1886 the United States witnessed a mass proletarian campaign for the eight-hour working day (see Note 581). Up to 65,000 people went on strike in Chicago in the first days of May. Workers clashed with police at a meeting held on
3 May. During the following day's protest meeting in Haymarket Square an agent provocateur threw a bomb which exploded and killed seven policemen and four workers. The police opened fire on the crowd, as a result of which a number were killed and over 200 wounded. Mass arrests were carried out and the leaders of the Chicago Labor Union brought before the court. Despite the broad campaign in defence of the accused in the United States and a number of European countries, four of them — Albert R. Parsons, August Spies, Adolph Fischer and George Engel— were hanged on 11 November 1887 on the decision of the US Supreme
In memory of the events of 1886 in Chicago, the International Socialists' Congress held in Paris in 1889 resolved to proclaim 1 May International Workers' Day.—

"The Knights of Labor" (The Noble Order of the Knights of Labour) is the name of an American workers' organisation founded in Philadelphia in 1869 and constituting a secret society until 1881. The bulk of the members of the 'Order' were unskilled workers, including a large number of Blacks. Its aims were to set up cooperatives and organise mutual assistance, and it took part in a considerable number of working-class campaigns. However, the leadership of the 'Order' to all intents and purposes rejected the idea of workers' taking part in political struggle and advocated cooperation between classes. In 1886 the leadership worked against the general strike, forbidding its members to take part. Rank-and-file members of the 'Order' nevertheless did so, and after this the 'Order' began to lose influence among the working masses, falling apart by the end of the 1890s

Theoretical ignorance is an attribute of all young nations, but so is speedy practical development. In America as in England no amount of exhortation will help until the need is really there. And in America it is there, as is a growing awareness of it. The entry of the indigenous working masses into the movement in America is for me one of the great events of 1886. As for the Germans over there, let the presently prosperous kind gradually assimilate with the Americans — they'll still be a step or two ahead of the latter and a nucleus will nevertheless remain which will still retain a theoretical grasp of the nature and progress of the movement as a whole, will keep the process of fermentation going and, eventually, rise to the top again.

The anarchist follies in America may prove advantageous; it is undesirable that the American workers, given their present wholly bourgeois level of thinking — high wages and short hours — should win victories too quickly. That might unduly reinforce the biassed TRADES UNION spirit.


Friedrich Engels

Letter to Laura Lafargue

29. May 1886


So I do believe, too, that the anarchist follies of Chicago will do much good.582 If the present American movement— which so far as it is not exclusively German, is still in the Trades Union stage — had got a great victory on the 8 hours question, Trades Unionism would have become a fixed and final dogma. While a mixed result will -help to show then that it is necessary to go beyond 'high wages and short hours'.


Engels is referring to the mass campaign for the eight-hour working day which developed in major centres of US industry (Chicago, New York, Pittsburgh, Cincinatti, St Louis, Boston, Baltimore, Milwaukee) in the spring of 1886. The campaign
culminated in a general strike and mass demonstrations on 1 May 1886 involving over 350,000 people. Almost 200,000 workers secured a shorter working day as a result.—

Whatever the mistakes and the Borniertheit of the leaders of the movement, and partly of the newly-awakening masses too, one thing is certain: the American working class is moving, and no mistake. And after a few false starts, they will get into the right track soon enough.
This appearance of the Americans upon the scene I consider one of the greatest events of the year.

A very good bit of work would be a series of pamphlets stating, in popular language, the contents of Das Kapital. The theory of surplus value No. 1; the history of the various forms of surplus value (cooperation, manufacture, modern industry) No. 2; accumulation and the history of primitive accumulation No. 3; the development of surplus value making in colonies [last chapter) No. 4 — this would be especially instructive in America, as it would give the economical history of that country, from a land of independent peasants to a centre of modern industry, and might be completed by specially American facts.

before the mass of the American working people will begin to read socialist literature. And for those that do read and will read, there is matter enough being provided, and least of all will Der Ursprung be missed by them. With the Anglo-Saxon mind, and especially with the eminently practical development it has taken in America, theory counts for nothing until imposed by dire necessity, and I count above all things upon the teaching our friends will receive by the consequences of their own blunders, to prepare them for theoretical schooling.

The entry of the Americans into the movement and the revival of the French movement by the three labour deputies and by Decazeville — these are the two events of world historic importance this
year. In America there's all sorts of tomfoolery going on — here the anarchists, there the KNIGHTS OF LABOR — but no matter; the thing has got going and will make rapid progress. There are still many disappointments in store — the wire-pullers of the old political parties are preparing covertly to take over the leadership of the budding workers' party—and colossal blunders will be made, but nevertheless, things will go faster there than anywhere else.




Friedrich Engels

Letter to Sorge

16-17 September 1886


In a country as unsophisticated as America which, though wholly without a feudal past, has evolved along purely bourgeois lines yet has uncritically taken over from England a mass of ideology deriving from feudal times, such as English common law, religion, sectarianism, and where the exigencies of practical work and of the concentration of capital have engendered a general contempt, only now diminishing
amongst the most highly educated and learned circles, for all theory — in such a country, the people will have to find out what their own social interests are by making one blunder after another.
Nor will the workers be spared this experience; the confusion of the TRADES UNIONS, the socialists, the KNIGHTS OF LABOR, etc., will persist for some time yet, until wisdom is born of their own misfortunes. But the main thing is that they are now in motion, that they are actually progressing, and that the spell has been broken; things will move fast, faster than anywhere else, even though the course they take may seem erratic and, from the theoretical standpoint, almost demented.


Friedrich Engels

Letter to Laura Lafargue

24. November 1886


I hope you have received the American letters I sent you yesterday, to-day I can keep my word and write. Our people have indeed hit upon a lucky moment for their journey,601 it coincides with the first formation of a real American working men's party and what was practically an immense success, the Henry George 'boom' in New York. 657 Master George is rather a confused sort of a body and being a Yankee, has a nostrum of his own, and not a very excellent one, but his confusion is a very fair expression of the present stage of development of the Anglo-American working class mind, and we cannot expect even American masses to arrive at theoretical perfection in six or
eight months — the age of this movement. And considering that the Germans in America are anything but a fair and adequate sample of the workmen of Germany, but rather of the elements the movement at home has eliminated — Lassalleans, disappointed ambitions, sectarians of all sorts— I for one am not sorry that the Americans start independently of them, or at least of their leadership. As a ferment the Germans can and will act, and at the same time undergo, themselves,
a good deal of useful and necessary fermentation. The unavoidable starting point, in America, are the Knights of Labor, who are a real power, and are sure to form the first embodiment of the movement.
Their absurd organisation and very slippery leaders — used to the methods of corrupt American partisanship — will very soon provoke a crisis within that body itself, and then a more adequate and more effective organisation can be developed from it. All this I think will not take very long in Yankeeland; the great point gained is that the political action of the working class as an independent party is henceforth established there.


Friedrich Engels

Letter to Kautsky

29. November 1886



In America, apart from New York, the real movement is running ahead of the Germans. The Americans' real organisation is the KNIGHTS OF LABOR which is as muddle-headed as the masses themselves.
But it is from this chaos that the movement will evolve, not from the German sections — the Germans, that is, who, for the past 20 years, have proved incapable of extracting from their theory what America needs.549 But this is just the moment when the Germans might exert a very enlightening influence — if only they had learnt English!




Friedrich Engels

Letter to Sorge

29 September 1886


The Henry George boom naturally brought a vast amount of dirty business to light, and I'm glad I wasn't there. Nevertheless, it was an epoch-making day. The Germans simply have not realised how they can use their theory as a lever that will set the American masses in motion; they themselves do not for the most part understand the theory and treat it in doctrinaire and dogmatic fashion as something which, having once been learnt by rote, is sufficient as it Stands for any and every need. To them it is a credo, not a guide to action. Besides which, they refuse to learn English on principle.

Hence the American masses have had to find a way of their own and would appear to have done so for the time being in the KNIGHTS OF LABOR whose muddle-headed principles and ridiculous organisation would seem to match their own muddle-headedness. From all that I hear, the KNIGHTS OF LABOR are a real power, particularly in New England and the West, and are daily becoming more so as a result of the brutality of the capitalist opposition. It is, I believe, necessary to work in their midst, to form, within this still fairly malleable mass, a nucleus of men who know the movement and its aims and will thus automatically take over the leadership of at least some part of it when, as is inevitable, the present 'Order' disintegrates. The worst aspect of the KNIGHTS OF LABOR is their political neutrality whose only result is the sharp practice of the Powderlys, etc. But this last has had its sting drawn by the response of the masses in the November elections, more especially in New York. In a country that has newly entered the movement, the first really crucial step is the formation by the workers of an independent political party, no matter how, so long as it is distinguishable as a labour party. And this step has been taken far sooner than we might have expected, and that's the main thing. That the first programme of this party should still be muddle-headed and extremely inadequate,3 that it should have picked Henry George for its figurehead, are unavoidable if merely transitory evils. The masses must have the time and the opportunity to evolve; and they will not get that opportunity until they have a movement of their own — no matter what its form, providing it is their own movement — in which

they are impelled onwards by their own mistakes and learn by bitter experience.

The movement in America is at the same stage as it was at home before 1848; the really intelligent chaps will at first play the same role over there as did the Communist League before 1848 among the working men's associations.13 Save that in America things will move infinitely faster; for it is completely unprecedented for a movement to

achieve such electoral successes after an existence of barely eight months. And what is still lacking, the bourgeois will make good; nowhere else irt the world do they behave so outrageously and tyranically a See Der Sozialist, No. 40, 2 October 1886.-b See F. Engels, 'Preface to the 1888 English Edition of the Manifesto of Ike Communist Party'.

304. Engels to Sorge. 29 November 1886 533 as there, and your judges knock Bismarck's imperial pettifoggers into a cocked hat. When the struggle is conducted by the bourgeois with weapons such as these, it will rapidly come quickly to a head and, unless we in Europe bestir ourselves, the Americans will soon steal a march on us. But just now it is doubly necessary to have a few chaps on our side who are thoroughly versed in theory and in well-tried tactics and who can also speak and write English, since the Americans, for good historical reasons, lag far behind in all theoretical matters; true, they did not bring with them from Europe any medieval institutions, but instead a mass of medieval traditions—religion, English common (feudal) law, superstition, spiritualism — in short, every kind of balderdash that was not immediately harmful to business and now comes in very handy for the stultification of the masses.

And if people are available whose clear grasp of theory enables them to tell the Americans what the consequences of their mistakes are likely to be, and make them see that any movement which does not constantly bear in mind that the ultimate goal is the destruction of the wage system, must necessarily go astray and come to nothing, then much silliness can be avoided and the process be considerably curtailed. But it must be done in English, the specifically German character must be sloughed off, and this the gentlemen of the Sozialist are hardly qualified to do, while those of the Volkszeitung may be shrewder, but only in regard to business.

The American elections this month made a tremendous impact on Europe. The absence up till now of a labour movement in England, and more especially in America, has been the great trump card of radical Republicans everywhere, notably in France. Now these chaps are utterly dumbfounded — Mr Clemenceau in particular who, on 2 November, witnessed the collapse of all that his policy was based on. 'Just look at America,' he never tired of saying, 'that's a real republic for you — no poverty and no labour movement!' And it's the same with the men of Progress93 and 'democrats' in Germany and over here — where they are just experiencing an incipient movement of their own. What has completely stunned these people is the fact that the movement is so strongly accentuated as a labour movement, and that it has sprung up so suddenly and with such force.


Friedrich Engels

Letter to F. Kelley-Wischnewetzky

28 December 1886


First you seem to me to treat New York a little as the Paris of America, and to overrate the importance, for the country at large, of the local New York movement with its local features. No doubt it has a great importance, but then the North-West with its background of a numerous farming population and its independent movement will hardly accept blindly the George theory.

Secondly the preface of this book is hardly the place for a thoroughgoing criticism of that theory, and offers even not the necessary space for it.

Thirdly I should have to study thoroughly Henry George's various writings and speeches (most of which I have not got) so as to render impossible all replies based on subterfuges and side-issues.

My preface will of course turn entirely on the immense stride made by the American working-men in the last ten months, and naturally also touch Henry George and his land scheme. But it cannot pretend to deal extensively with it. Nor do I think the time for that has come.

It is far more important that the movement should spread, proceed harmoniously, take root and embrace as much as possible the whole American proletariat, than that it should start and proceed, from the beginning, on theoretically perfectly correct lines. There is no better road to theoretical clearness of comprehension than to learn by one's own mistakes, 'durch Schaden klug werden'. And for a whole large class, there is no other road, especially for a nation so eminently practical and so contemptuous of theory as the Americans. The great thing is to get the working-class to move as a class; that once obtained, they will soon find the right direction, and all who resist, Henry George or Powderly, will be left out in the cold with small sects of their own.

Therefore I think also the Knights of Labor6 0 9 a most important factor in the movement which ought not to be pooh-poohed from without but to be revolutionised from within, and I consider that many of the Germans there have made a grievous mistake when they tried, in the face of a mighty and glorious movement not of their creation, to make of their imported and not always understood theory a kind of alleinseligmachendes Dogma,* and to keep aloof from any movement which did not accept that dogma. Our theory is not a dogma but the exposition of a process of evolution, and that process involves successive phases. To expect that the Americans will start with the full consciousness of the theory worked out in older industrial countries is to expect the impossible. What the Germans ought to do is to act up to their own theory — if they understand it, as we did in 1845 and 1848,— to go in for any real general working-class movement, accept its faktischeh starting point as such, and work it gradually up to the theoretical level by pointing out how every mistake made, every reverse suffered, was a necessary consequence of mistaken theoretical views in the original programme: they ought, in the words of the Kommunistischen Manifest: Hn der Gegenwart der Bewegung die Zukunft der Bewegung zu repräsentieren' . But above all give the movement time to consolidate, do not make the inevitable confusion of the first start, worse confounded by forcing down people's throats things which, at present, they cannot properly understand, but which they will soon learn. A million or two of working-men's votes next November for a the only saving dogma - b actual - c 'in the movement of the present to represent the future of the movement' a bona fide working-men's party is worth infinitely more at present than a hundred thousand votes for a doctrinally perfect platform.

The very first attempt — soon to be made if the movement progresses— to consolidate the moving masses on a national basis — will bring them all face to face, Georgites, Knights of Labor, Trade-Unionists and all; and if our German friends by that time have learnt enough of the language of the country to go in for a discussion, then will be the time for them to criticise the views of the others and thus, by showing up the inconsistencies of the various standpoints, to bring them gradually to understand their own actual position, the position made for them by the correlation of capital and wage labour. But anything that might delay or prevent that national consolidation of the working-men's party — on no matter what platform—I should consider a great mistake, and therefore I do not think the time has arrived to speak out fully and exhaustively either with regard to Henry George or the Knights of Labor.






The Haymarket massacre

The Haymarket massacre or Haymarket riot was the aftermath of a bombing that took place at a labor demonstration on Tuesday May 4, 1886, at Haymarket Square in Chicago. It began as a peaceful rally in support of workers striking for an eight-hour day and in reaction to the killing of several workers the previous day by the police. An unknown person threw a dynamite bomb at police as they acted to disperse the public meeting. The bomb blast and ensuing gunfire resulted in the deaths of seven police officers and at least four civilians; scores of others were wounded.

In the internationally publicized legal proceedings that followed, eight anarchists were convicted of conspiracy. The evidence was that one of the defendants may have built the bomb, but none of those on trial had thrown it. Seven were sentenced to death and one to a term of 15 years in prison. The death sentences of two of the defendants were commuted by Illinois governor Richard J. Oglesby to terms of life in prison, and another committed suicide in jail rather than face the gallows. The other four were hanged on November 11, 1887. In 1893, Illinois' new governor John Peter Altgeld pardoned the remaining defendants and criticized the trial.

The Haymarket affair is generally considered significant as the origin of international May Day observances for workers. The site of the incident was designated a Chicago Landmark in 1992, and a public sculpture was dedicated there in 2004. In addition, the Haymarket Martyrs' Monument at the defendants' burial site in nearby Forest Park was designated a National Historic Landmark in 1997.

No single event has influenced the history of labor in Illinois, the United States, and even the world, more than the Chicago Haymarket Affair. It began with a rally on May 4, 1886, but the consequences are still being felt today. Although the rally is included in American history textbooks, very few present the event accurately or point out its significance.


Following the Civil War, particularly following the Depression of 1873–79, there was a rapid expansion of industrial production in the United States. Chicago was a major industrial center and tens of thousands of German and Bohemian immigrants were employed at about $1.50 a day. American workers worked on average slightly over 60 hours, during a six-day work week. The city became a center for many attempts to organize labor's demands for better working conditions. Employers responded with anti-union measures, such as firing and blacklisting union members, locking out workers, recruiting strikebreakers; employing spies, thugs, and private security forces and exacerbating ethnic tensions in order to divide the workers. Mainstream newspapers supported business interests, and were opposed by the labor and immigrant press. During the economic slowdown between 1882 and 1886, socialist and anarchist organizations were active. Membership of the Knights of Labor, which rejected socialism and radicalism, but supported the 8-hour work day, grew from 70,000 in 1884 to over 700,000 by 1886. In Chicago, the anarchist movement of several thousand, mostly immigrant, workers centered about the German-language newspaper Arbeiter-Zeitung ("Workers' Times"), edited by August Spies. Other anarchists operated a militant revolutionary force with an armed section that was equipped with guns and explosives. Its revolutionary strategy centered around the belief that successful operations against the police and the seizure of major industrial centers would result in massive public support by workers, revolution, destroy capitalism, and establish a socialist economy.

May Day parade and strikes

In October 1884, a convention held by the Federation of Organized Trades and Labor Unions unanimously set May 1, 1886, as the date by which the eight-hour work day would become standard. As the chosen date approached, U.S. labor unions prepared for a general strike in support of the eight-hour day.

On Saturday, May 1, thousands of workers went on strike and rallies were held throughout the United States, with the cry, "Eight-hour day with no cut in pay." Estimates of the number of striking workers across the U.S. range from 300,000 to half a million. In New York City the number of demonstrators was estimated at 10,000 and in Detroit at 11,000. In Milwaukee, Wisconsin, some 10,000 workers turned out. In Chicago, the movement's center, an estimated 30,000-to-40,000 workers had gone on strike and there were perhaps twice as many people out on the streets participating in various demonstrations and mrches,as, for example, a march by 10,000 men employed in the Chicago lumber yards.Though participants in these events added up to 80,000, it is disputed whether there was a march of that number down Michigan Avenue led by anarchist Albert Parsons, founder of the International Working People's Association [IWPA] and his wife Lucy and their children.

The words "Workingmen Arm Yourselves and Appear in Full Force!" were removed from the revised flier.

On May 3, striking workers in Chicago met near the McCormick Harvesting Machine Company plant. Union molders at the plant had been locked out since early February and the predominantly Irish-American workers at McCormick had come under attack from Pinkerton guards during an earlier strike action in 1885. This event, along with the eight-hour militancy of McCormick workers, had gained the strikers some respect and notoriety around the city. By the time of the 1886 general strike, strikebreakers entering the McCormick plant were under protection from a garrison of 400 police officers. Although half of the replacement workers defected to the general strike on May 1, McCormick workers continued to harass strikebreakers as they crossed the picket lines.

Speaking to a rally outside the plant on May 3, August Spies advised the striking workers to "hold together, to stand by their union, or they would not succeed." Well-planned and coordinated, the general strike to this point had remained largely nonviolent. When the end-of-the-workday bell sounded, however, a group of workers surged to the gates to confront the strikebreakers. Despite calls for calm by Spies, the police fired on the crowd. Two McCormick workers were killed (although some newspaper accounts said there were six fatalities). Spies would later testify, "I was very indignant. I knew from experience of the past that this butchering of people was done for the express purpose of defeating the eight-hour movement."

Outraged by this act of police violence, local anarchists quickly printed and distributed fliers calling for a rally the following day at Haymarket Square (also called the Haymarket), which was then a bustling commercial center near the corner of Randolph Street and Desplaines Street. Printed in German and English, the fliers claimed that the police had murdered the strikers on behalf of business interests and urged workers to seek justice. The first batch of fliers contain the words Workingmen Arm Yourselves and Appear in Full Force! When Spies saw the line, he said he would not speak at the rally unless the words were removed from the flier. All but a few hundred of the fliers were destroyed, and new fliers were printed without the offending words. More than 20,000 copies of the revised flier were distributed.

The rally began peacefully under a light rain on the evening of May 4. August Spies, Albert Parsons, and Samuel Fielden spoke to a crowd estimated variously between 600 and 3,000 while standing in an open wagon adjacent to the square on Des Plaines Street. A large number of on-duty police officers watched from nearby.

Paul Avrich, a historian specializing in the study of anarchism, quotes Spies as saying:

There seems to prevail the opinion in some quarters that this meeting has been called for the purpose of inaugurating a riot, hence these warlike preparations on the part of so-called 'law and order.' However, let me tell you at the beginning that this meeting has not been called for any such purpose. The object of this meeting is to explain the general situation of the eight-hour movement and to throw light upon various incidents in connection with it.

Following Spies' speech, the crowd was addressed by Parsons, the Alabama-born editor of the radical English-language weekly The Alarm. The crowd was so calm that Mayor Carter Harrison, Sr., who had stopped by to watch, walked home early. Parsons spoke for almost an hour before standing down in favor of the last speaker of the evening, the British socialist Samuel Fielden, who delivered a brief ten-minute address. Many of the crowd had already left as the weather was deteriorating.

A New York Times article, with the dateline May 4, and headlined "Rioting and Bloodshed in the Streets of Chicago ... Twelve Policemen Dead or Dying", reported that Fielden spoke for 20 minutes, alleging that his words grew "wilder and more violent as he proceeded".Another New York Times article, headlined "Anarchy’s Red Hand" and dated May 6, opens with: "The villainous teachings of the Anarchists bore bloody fruit in Chicago tonight and before daylight at least a dozen stalwart men will have laid down their lives as a tribute to the doctrine of Herr Johann Most." It refers to the strikers as a "mob" and uses quotation marks around the term "workingmen".

Bombing and gunfire

A map of the bombing published by the Chicago Tribune on May 5, 1886

At about 10:30 pm, just as Fielden was finishing his speech, police arrived en masse, marching in formation towards the speakers' wagon, and ordered the rally to disperse.[36] Fielden insisted that the meeting was peaceful. Police Inspector John Bonfield, proclaimed:

I command you [addressing the speaker] in the name of the law to desist and you [addressing the crowd] to disperse.

A home-made bomb with a brittle metal casing filled with dynamite and ignited by a fuse,[39] was thrown into the path of the advancing police. Its fuse briefly sputtered, then the bomb exploded, killing policeman Mathias J. Degan with flying metal fragments and mortally wounding six other officers.

Witnesses maintained that immediately after the bomb blast there was an exchange of gunshots between police and demonstrators. Accounts vary widely as to who fired first and whether any of the crowd fired at the police. Historian Paul Avrich maintains that the police fired on the fleeing demonstrators, reloaded and then fired again, killing four and wounding as many as 70 people. What is not disputed is that in less than five minutes the square was empty except for the casualties. According to the May 4 New York Times demonstrators began firing at the police, who then returned fire. In his report on the incident, Inspector Bonfield wrote that he "gave the order to cease firing, fearing that some of our men, in the darkness might fire into each other".An anonymous police official told the Chicago Tribune, "A very large number of the police were wounded by each other's revolvers. ... It was every man for himself, and while some got two or three squares away, the rest emptied their revolvers, mainly into each other."

In all, seven policemen and at least four workers were killed. Another policeman died two years after the incident from complications related to injuries received on that day. About 60 policemen were wounded in the incident. They were carried, along with some other wounded people, into a nearby police station. Police captain Michael Schaack later wrote that the number of wounded workers was "largely in excess of that on the side of the police". The Chicago Herald described a scene of "wild carnage" and estimated at least fifty dead or wounded civilians lay in the streets. It is unclear how many civilians were wounded since many were afraid to seek medical attention, fearing arrest. They found aid where they could.

Aftermath and red scare

A harsh anti-union clampdown followed the Haymarket incident. There was a massive outpouring of community and business support for the police and many thousands of dollars were donated to funds for their medical care and to assist their efforts. The entire labor and immigrant community, particularly Germans and Bohemians, came under suspicion. Police raids were carried out on homes and offices of suspected anarchists. Scores of suspects, many only remotely related to the Haymarket affair, were arrested. Casting legal requirements such as search warrants aside, Chicago police squads subjected the labor activists of Chicago to an eight-week shakedown, ransacking their meeting halls and places of business. The emphasis was on the speakers at the Haymarket rally and the newspaper, Arbeiter-Zeitung. A small group of anarchists were discovered to have been engaged in making bombs on the same day as the incident, including round ones like the one used in Haymarket Square.

Newspaper reports declared that anarchist agitators were to blame for the "riot", a view adopted by an alarmed public. As time passed, press reports and illustrations of the incident became more elaborate. Coverage was national, then international. Among property owners, the press, and other elements of society, a consensus developed that suppression of anarchist agitation was necessary. While for their part, union organizations such as The Knights of Labor and craft unions were quick to disassociate themselves from the anarchist movement and to repudiate violent tactics as self-defeating.Many workers, on the other hand, believed that men of the Pinkerton agency were responsible because of the agency's tactic of secretly infiltrating labor groups and its sometimes violent methods of strike breaking.

Legal proceedings

The police assumed that an anarchist had thrown the bomb as part of a planned conspiracy; their problem was how to prove it. On the morning of May 5, they raided the offices of the Arbeiter-Zeitung, arresting its editor August Spies, and his brother (who was not charged). Also arrested were editorial assistant Michael Schwab and Adolph Fischer, a typesetter. A search of the premises resulted in the discovery of the "Revenge Poster" and other evidence considered incriminating by the prosecution.

On May 7 police searched the premises of Louis Lingg where they found a number of bombs and bomb-making materials. Lingg's landlord William Seliger was also arrested but cooperated with police and identified Lingg as a bomb maker and was not charged. An associate of Spies, Balthazar Rau, suspected as the bomber, was traced to Omaha and brought back to Chicago. After interrogation, Rau offered to cooperate with police. He alleged that the defendants had experimented with dynamite bombs and accused them of having published what he said was a code word, "Ruhe" ("peace"), in the Arbeiter-Zeitung as a call to arms at Haymarket Square.

The defendants

Rudolf Schnaubelt, the police’s lead suspect as the bomb thrower, was arrested twice early on and released. By May 14, when it became apparent he had played a significant role in the event, he had fled the country. William Seliger, who had turned state's evidence and testified for the prosecution, was not charged. On June 4, 1886, seven other suspects, however, were indicted by the grand jury and stood trial for being accessories to the murder of Degan.Of these, only two had been present when the bomb exploded. Newspaper editor August Spies and Samuel Fielden had spoken at the peaceful rally and were stepping down from the speaker's wagon in compliance with police orders to disperse just before the bomb went off. Two others had been present at the beginning of the rally but had left and were at Zepf's Hall, an anarchist rendezvous, at the time of the explosion. They were: Arbeiter-Zeitung typesetter Adolph Fischer and the well-known activist Albert Parsons, who had spoken for an hour at the Haymarket rally before going to Zepf's. Parsons, who believed that the evidence against them all was weak, subsequently voluntarily turned himself in, in solidarity with the accused. A third man, Spies's assistant editor Michael Schwab (who was the brother-in-law of Schnaubelt) was arrested since he was speaking at another rally at the time of the bombing (he was also later pardoned). Not directly tied to the Haymarket rally, but arrested because they were notorious for their militant radicalism were George Engel (who was at home playing cards on that day), and Louis Lingg, the hot-headed bomb maker denounced by his associate, Seliger. Another defendant who had not been present that day was Oscar Neebe, an American-born citizen of German descent who was associated with the Arbeiter-Zeitung and had attempted to revive it in the aftermath of the Haymarket riot.

Of the eight defendants, five – Spies, Fischer, Engel, Lingg and Schwab – were German-born immigrants; a sixth, Neebe, was a U.S.-born citizen of German descent. Only the remaining two, Parsons and Fielden, born in the U.S. and England, respectively, were of British heritage.

The trial, Illinois vs. August Spies et al., began on June 21, 1886, and went on until August 11. The trial was conducted in an atmosphere of extreme prejudice by both public and media toward the defendants. It was presided over by Judge Joseph Gary. Judge Gary displayed open hostility to the defendants, consistently ruled for the prosecution, and failed to maintain decorum. A motion to try the defendants separately was denied. The defense counsel included Sigmund Zeisler, William Perkins Black, William Foster, and Moses Salomon. Selection of the jury was extraordinarily difficult, lasting three weeks, and nearly one thousand people called. All union members and anyone who expressed sympathy toward socialism were dismissed. In the end a jury of 12 was seated, most of whom confessed prejudice towards the defendants. Despite their professions of prejudice Judge Gary seated those who declared that despite their prejudices they would acquit if the evidence supported it, refusing to dismiss for prejudice. Eventually the peremptory challenges of the defense were exhausted. Frustrated by the hundreds of jurors who were being dismissed, a bailiff was appointed who selected jurors rather than calling them at random. The bailiff proved prejudiced himself and selected jurors who seemed likely to convict based on their social position and attitudes toward the defendants. The prosecution, led by Julius Grinnell, argued that since the defendants had not actively discouraged the person who had thrown the bomb, they were therefore equally responsible as conspirators. The jury heard the testimony of 118 people, including 54 members of the Chicago Police Department and the defendants Fielden, Schwab, Spies and Parsons. Albert Parsons' brother claimed there was evidence linking the Pinkertons to the bomb. This reflected a widespread belief among the strikers.

Exhibit 129a from the Haymarket trial: Chemists testified that the bombs found in Lingg's apartment, including this one, resembled the chemical signature of shrapnel from the Haymarket bomb.

Police investigators under Captain Michael Schaack had a lead fragment removed from a policeman's wounds chemically analyzed. They reported that the lead used in the casing matched the casings of bombs found in Lingg's home. A metal nut and fragments of the casing taken from the wound also roughly matched bombs made by Lingg. Schaack concluded, on the basis of interviews, that the anarchists had been experimenting for years with dynamite and other explosives, refining the design of their bombs before coming up with the effective one used at the Haymarket.

At the last minute, when it was discovered that instructions for manslaughter had not been included in the submitted instructions, the jury was called back, and the instructions were given.

Verdict and contemporary reactions

The jury returned guilty verdicts for all eight defendants. Before being sentenced, Neebe told the court that Schaack's officers were among the city's worst gangs, ransacking houses and stealing money and watches. Schaack laughed and Neebe retorted, "You need not laugh about it, Captain Schaack. You are one of them. You are an anarchist, as you understand it. You are all anarchists, in this sense of the word, I must say." Judge Gary sentenced seven of the defendants to death by hanging and Neebe to 15 years in prison. The sentencing provoked outrage from labor and workers' movements and their supporters, resulting in protests around the world, and elevating the defendants to the status of martyrs, especially abroad. Portrayals of the anarchists as bloodthirsty foreign fanatics in the press along with the 1889 publication of Captain Schaack's sensational account, Anarchy and Anarchism, on the other hand, inspired widespread public fear and revulsion against the strikers and general anti-immigrant feeling, polarizing public opinion.

In an article datelined May 4, entitled "Anarchy’s Red Hand", The New York Times had described the incident as the "bloody fruit" of "the villainous teachings of the Anarchists." The Chicago Times described the defendants as "arch counselors of riot, pillage, incendiarism and murder"; other reporters described them as "bloody brutes", "red ruffians", "dynamarchists", "bloody monsters", "cowards", "cutthroats", "thieves", "assassins", and "fiends". The journalist George Frederic Parsons wrote a piece for The Atlantic Monthly in which he identified the fears of middle-class Americans concerning labor radicalism, and asserted that the workers had only themselves to blame for their troubles.[66] Edward Aveling remarked, "If these men are ultimately hanged, it will be the Chicago Tribune that has done it." Schaack, who had led the investigation, was dismissed from the police force for allegedly having fabricated evidence in the case but was reinstated in 1892.


The case was appealed in 1887 to the Supreme Court of Illinois,[69] then to the United States Supreme Court where the defendants were represented by John Randolph Tucker, Roger Atkinson Pryor, General Benjamin F. Butler and William P. Black. The petition for certiorari was denied.

Commutations and suicide

After the appeals had been exhausted, Illinois Governor Richard James Oglesby commuted Fielden's and Schwab's sentences to life in prison on November 10, 1887. On the eve of his scheduled execution, Lingg committed suicide in his cell with a smuggled blasting cap which he reportedly held in his mouth like a cigar (the blast blew off half his face and he survived in agony for six hours).


Execution of defendants —Engel, Fischer, Parsons, and Spies

The next day (November 11, 1887) four defendants—Engel, Fischer, Parsons, and Spies—were taken to the gallows in white robes and hoods. They sang the Marseillaise, then the anthem of the international revolutionary movement. Family members including Lucy Parsons, who attempted to see them for the last time, were arrested and searched for bombs (none were found). According to witnesses, in the moments before the men were hanged, Spies shouted, "The time will come when our silence will be more powerful than the voices you strangle today." In their last words, the men reportedly praised anarchism. Parsons tried to request to speak, but he was cut off when the signal was given to open the trap door. Witnesses reported that the condemned men did not die immediately when they dropped, but strangled to death slowly, a sight which left the spectators visibly shaken.

Identity of the bomber

Notwithstanding the convictions for conspiracy, no actual bomber was ever brought to trial, "and no lawyerly explanation could ever make a conspiracy trial without the main perpetrator in the conspiracy seem completely legitimate." Historians such as James Joll and Timothy Messer-Kruse say the evidence points to Rudolph Schnaubelt, brother-in-law of Schwab, as the likely perpetrator. Howard Zinn, in A People's History of the United States also pointed towards Schnaubelt, suggesting he was a provocateur, posing as an anarchist, who threw the bomb so police would have a pretext to arrest leaders of Chicago's anarchist movement. However, Paul Avrich disputes this claim as being "sheer speculation and utterly without foundation." Avrich argues that Schnaubelt's appearance did not match the description of the bomber and that his behavior was inconsistent with either being the culprit or a mole.

Pardon and historical characterization

Among supporters of the labor movement in the United States and abroad and others, the trial was widely believed to have been unfair, and even a serious miscarriage of justice. Prominent people such as novelist William Dean Howells; celebrated attorney Clarence Darrow; poet and playwright Oscar Wilde; and playwright George Bernard Shaw strongly condemned it. On June 26, 1893, Illinois Governor John Peter Altgeld, the progressive governor of Illinois, himself a German immigrant, signed pardons for Fielden, Neebe, and Schwab, calling them victims of "hysteria, packed juries, and a biased judge" and noting that the state "has never discovered who it was that threw the bomb which killed the policeman, and the evidence does not show any connection whatsoever between the defendants and the man who threw it." Altgeld also faulted the city of Chicago for failing to hold Pinkerton guards responsible for repeated use of lethal violence against striking workers. Altgeld's actions concerning labor were used to defeat his reelection.

Soon after the trial, anarchist Dyer Lum wrote a history of the trial critical of the prosecution. In 1888, George McLean, and in 1889, police captain Michael Shack, wrote accounts from the opposite perspective. Awaiting sentencing, each of the defendants wrote their own autobiographies (edited and published by Philip Foner in 1969), and later activist Lucy Parsons published a biography of her condemned husband Albert Parsons. Fifty years after the event, Henry Davis, wrote a history, which was superseded in another scholarly treatment by Paul Avrich in 1984, and a "social history" of the era by Bruce C. Nelson in 1988. In 2006, labor historian, James Green, wrote a popular history.

Christopher Thale writes in the Encyclopedia of Chicago that lacking credible evidence regarding the bombing, "...the prosecution focused on the writings and speeches of the defendants." He further notes that the conspiracy charge was legally unprecedented, the Judge was "partisan," and all the jurors admitted prejudice against the defendants. Historian Carl Smith writes, "The visceral feelings of fear and anger surrounding the trial ruled out anything but the pretense of justice right from the outset." Smith notes that scholars have long considered the trial a "notorious" "miscarriage of justice." In a review somewhat more critical of the defendants, historian Jon Teaford concludes that "[t]he tragedy of Haymarket is the American justice system did not protect the damn fools who most needed that protection... It is the damn fools who talk too much and too wildly who are most in need of protection from the state."[In 2011, labor historian Timothy Messer-Kruse published a history. Based on his examination of the trial transcripts and other archival material, he concludes there is abundant evidence connecting defendants to advocacy of violence and preparations for it. He argues that Chicago's anarchists were indeed "part of an international terrorist network and did hatch a conspiracy to attack police with bombs and guns that May Day weekend"; and he calls the evidence establishing the guilt of "most of the defendants"[vague] "overwhelming." Moreover, Messer-Kruse opines that the trial was fair "by the standards of the age" and the jury representative. According to him, "The tragic end of the story was the product not of prosecutorial eagerness to see the anarchists hang, but largely due to a combination of the incompetence of the defendant's lawyers and their willingness to use the trial to vindicate anarchism rather than to save the necks of their clients."

During the late 20th century, scholars doing research into the Haymarket affair were surprised to learn that much of the primary source documentation relating to the incident (beside materials concerning the trial) was not in Chicago, but had been transferred to then-communist East Berlin.

Effects on the labor movement and May Day

The Haymarket affair was a setback for the American labor movement and its fight for the eight-hour day. Yet it also can be seen as strengthening its resistance, especially in Chicago, where, as historian Nathan Fine points out, trade union activities continued to show signs of growth and vitality, culminating later in 1886 with the establishment of the Labor Party of Chicago.

Fine observes:

[T]he fact is that despite police repression, newspaper incitement to hysteria, and organization of the possessing classes, which followed the throwing of the bomb on May 4, the Chicago wage earners only united their forces and stiffened their resistance. The conservative and radical central bodies – there were two each of the trade unions and two also of the Knights of Labor — the socialists and the anarchists, the single taxers and the reformers, the native born...and the foreign born Germans, Bohemians, and Scandinavians, all got together for the first time on the political field in the summer following the Haymarket affair.... [T]he Knights of Labor doubled its membership, reaching 40,000 in the fall of 1886. On Labor Day the number of Chicago workers in parade led the country.

On the first anniversary of the event, May 4, 1887, the New-York Tribune published an interview with Senator Leland Stanford, in which he addressed the consensus that "the conflict between capital and labor is intensifying" and articulated the vision advocated by the Knights of Labor for an industrial system of worker-owned co-operatives, another among the strategies pursued to advance the conditions of laborers. The interview was republished as a pamphlet to include the bill Stanford introduced in the Senate to foster co-operatives.

Popular pressure continued for the establishment of the 8-hour day. At the convention of the American Federation of Labor (AFL) in 1888, the union decided to campaign for the shorter workday again. May 1, 1890, was agreed upon as the date on which workers would strike for an eight-hour work day.

This sympathetic engraving by English Arts and Crafts illustrator Walter Crane of "The Anarchists of Chicago" was widely circulated among anarchists, socialists, and labor activists.

In 1889, AFL president Samuel Gompers wrote to the first congress of the Second International, which was meeting in Paris. He informed the world's socialists of the AFL's plans and proposed an international fight for a universal eight-hour work day. In response to Gompers's letter, the Second International adopted a resolution calling for "a great international demonstration" on a single date so workers everywhere could demand the eight-hour work day. In light of the Americans' plan, the International adopted May 1, 1890 as the date for this demonstration.

A secondary purpose behind the adoption of the resolution by the Second International was to honor the memory of the Haymarket martyrs and other workers who had been killed in association with the strikes on May 1, 1886. Historian Philip Foner writes "[t]here is little doubt that everyone associated with the resolution passed by the Paris Congress knew of the May 1 demonstrations and strikes for the eight-hour day in 1886 in the United States ... and the events associated with the Haymarket tragedy."

The first international May Day was a spectacular success. The front page of the New York World on May 2, 1890, was devoted to coverage of the event. Two of its headlines were "Parade of Jubilant Workingmen in All the Trade Centers of the Civilized World" and "Everywhere the Workmen Join in Demands for a Normal Day."The Times of London listed two dozen European cities in which demonstrations had taken place, noting there had been rallies in Cuba, Peru and Chile. Commemoration of May Day became an annual event the following year.

The association of May Day with the Haymarket martyrs has remained strong in Mexico. Mary Harris "Mother" Jones was in Mexico on May 1, 1921, and wrote of the "day of 'fiestas'" that marked "the killing of the workers in Chicago for demanding the eight-hour day". In 1929 The New York Times referred to the May Day parade in Mexico City as "the annual demonstration glorifying the memory of those who were killed in Chicago in 1887." The New York Times described the 1936 demonstration as a commemoration of "the death of the martyrs in Chicago." In 1939 Oscar Neebe's grandson attended the May Day parade in Mexico City and was shown, as his host told him, "how the world shows respect to your grandfather".

The influence of the Haymarket affair was not limited to the celebration of May Day. Emma Goldman, the activist and political theorist, was attracted to anarchism after reading about the incident and the executions, which she later described as "the events that had inspired my spiritual birth and growth." She considered the Haymarket martyrs to be "the most decisive influence in my existence". Her associate, Alexander Berkman also described the Haymarket anarchists as "a potent and vital inspiration." Others whose commitment to anarchism crystallized as a result of the Haymarket affair included Voltairine de Cleyre and "Big Bill" Haywood, a founding member of the Industrial Workers of the World.Goldman wrote to historian Max Nettlau that the Haymarket affair had awakened the social consciousness of "hundreds, perhaps thousands, of people".

Suspected bombers

While admitting none of the defendants were involved in the bombing, the prosecution made the argument that Lingg had built the bomb and two prosecution witnesses (Harry Gilmer and Malvern Thompson) tried to imply the bomb thrower was helped by Spies, Fischer and Schwab. The defendants claimed they had no knowledge of the bomber at all.

Several activists, including Dyer Lum (a close associate of the defendants who wrote an account of the case in 1891), Voltairine de Cleyre and Robert Reitzel, later hinted they knew who the bomber was. Writers and other commentators have speculated about many possible suspects:

Rudolph Schnaubelt was indicted but fled the country. From this photograph, a prosecution witness identified Schnaubelt as the bomber.

  • Rudolph Schnaubelt (1863–1901) was an activist and the brother-in law of Michael Schwab. He was at the Haymarket when the bomb exploded. Schnaubelt was indicted with the other defendants but fled the city and later the country before he could be brought to trial. He was the detectives' lead suspect, and state witness Gilmer testified he saw Schnaubelt throw the bomb, identifying him from a photograph in court. Schnaubelt later sent two letters from London disclaiming all responsibility, writing, "If I had really thrown this bomb, surely I would have nothing to be ashamed of, but in truth I never once thought of it." He is the most generally accepted and widely known suspect and figured as the bomb thrower in The Bomb, Frank Harris's 1908 fictionalization of the tragedy. Written from Schnaubelt's point of view, the story opens with him confessing on his deathbed. However, Harris's description was fictional and those who knew Schnaubelt vehemently criticized the book.

  • George Schwab was a German shoemaker who died in 1924. German anarchist Carl Nold claimed he learned Schwab was the bomber through correspondence with other activists but no proof ever emerged. Historian Paul Avrich also suspected him but noted that while Schwab was in Chicago, he had only arrived days before. This contradicted statements by others that the bomber was a well-known figure in Chicago.

  • George Meng (b. around 1840) was a German anarchist and teamster who owned a small farm outside of Chicago where he had settled in 1883 after emigrating from Bavaria. Like Parsons and Spies, he was a delegate at the Pittsburgh Congress and a member of the IWPA. Meng's granddaughter, Adah Maurer, wrote Paul Avrich a letter in which she said that her mother, who was 15 at the time of the bombing, told her that her father was the bomber. Meng died sometime before 1907 in a saloon fire. Based on his correspondence with Maurer, Avrich concluded that there was a "strong possibility" that the little-known Meng may have been the bomber.

  • An agent provocateur was suggested by some members of the anarchist movement. Albert Parsons believed the bomber was a member of the police or the Pinkertons trying to undermine the labor movement. However, this contradicts the statements of several activists who said the bomber was one of their own. Lucy Parsons and Johann Most rejected this notion. Dyer Lum said it was "puerile" to ascribe "the Haymarket bomb to a Pinkerton."

  • A disgruntled worker was widely suspected. When Adolph Fischer was asked if he knew who threw the bomb, he answered, "I suppose it was some excited workingman." Oscar Neebe said it was a "crank."Governor Altgeld speculated the bomb thrower might have been a disgruntled worker who was not associated with the defendants or the anarchist movement but had a personal grudge against the police. In his pardoning statement, Altgeld said the record of police brutality towards the workers had invited revenge adding, "Capt. Bonfield is the man who is really responsible for the deaths of the police officers."

  • Klemana Schuetz was identified as the bomber by Franz Mayhoff, a New York anarchist and fraudster, who claimed in an affidavit that Schuetz had once admitted throwing the Haymarket bomb. August Wagener, Mayhoff's attorney, sent a telegram from New York to defense attorney Captain William Black the day before the executions claiming knowledge of the bomber's identity. Black tried to delay the execution with this telegram but Governor Oglesby refused. It was later learned that Schuetz was the primary witness against Mayhoff at his trial for insurance fraud, so Mayhoff's affidavit has never been regarded as credible by historians.

  • Thomas Owen was a carpenter from Pennsylvania. Severely injured in an accident a week before the executions, Owen reportedly confessed to the bombing on his deathbed by saying, "I was at the Haymarket riot and am an anarchist and say that I threw a bomb in that riot." He was an anarchist and apparently had been in Chicago at the time but other accounts note that long before his accident he had said he was at the Haymarket and saw the bomb thrower. Owen may have been trying to save the condemned men.

  • Reinold "Big" Krueger was killed by police either in the melee after the bombing or in a separate disturbance the next day and has been named as a suspect but there is no supporting evidence.

  • A mysterious outsider was reported by John Philip Deluse, a saloon keeper in Indianapolis who claimed he encountered a stranger in his saloon the day before the bombing. The man was carrying a satchel and on his way from New York to Chicago. According to Deluse, the stranger was interested in the labor situation in Chicago, repeatedly pointed to his satchel and said, "You will hear of some trouble there very soon." Parsons used Deluse's testimony to suggest the bomb thrower was sent by eastern capitalists. Nothing more was ever learned about Deluse's claim.

Lingg, Spies, Fischer, Engel, and Parsons were buried at the German Waldheim Cemetery (later merged with Forest Home Cemetery) in Forest Park, Illinois, a suburb of Chicago. Schwab and Neebe were also buried at Waldheim when they died, reuniting the "Martyrs." In 1893, the Haymarket Martyrs' Monument by sculptor Albert Weinert was raised at Waldheim. Over a century later, it was designated a National Historic Landmark by the United States Department of the Interior.

Throughout the 20th century, activists such as Emma Goldman chose to be buried near the Haymarket Martyrs' Monument graves.

Workers finish installing Gelert's statue of a Chicago policeman in Haymarket Square, 1889. The statue now stands at the Chicago Police Headquarters.

In 1889, a commemorative nine-foot (2.7 meter) bronze statue of a Chicago policeman by sculptor Johannes Gelert was erected in the middle of Haymarket Square with private funds raised by the Union League Club of Chicago. The statue was unveiled on May 30, 1889, by Frank Degan, the son of Officer Mathias Degan. On May 4, 1927, the 41st anniversary of the Haymarket affair, a streetcar jumped its tracks and crashed into the monument. The motorman said he was "sick of seeing that policeman with his arm raised". The city restored the statue in 1928 and moved it to Union Park. During the 1950s, construction of the Kennedy Expressway erased about half of the old, run-down market square, and in 1956, the statue was moved to a special platform built for it overlooking the freeway, near its original location.

The statue-less pedestal of the police monument on the 100th anniversary of the Haymarket affair in May 1986; the pedestal has since been removed.

The Haymarket statue was vandalized with black paint on May 4, 1968, the 82nd anniversary of the Haymarket affair, following a confrontation between police and demonstrators at a protest against the Vietnam War.[126] On October 6, 1969, shortly before the "Days of Rage" protests, the statue was destroyed when a bomb was placed between its legs. Weatherman took credit for the blast, which broke nearly 100 windows in the neighborhood and scattered pieces of the statue onto the Kennedy Expressway below.[127] The statue was rebuilt and unveiled on May 4, 1970, to be blown up yet again by Weatherman on October 6, 1970.[126][127] The statue was rebuilt, again, and Mayor Richard J. Daley posted a 24 hour police guard at the statue.[127] This guard cost $67,440 per year.[128] In 1972, it was moved to the lobby of the Central Police Headquarters, and in 1976 to the enclosed courtyard of the Chicago police academy.[126] For another three decades the statue's empty, graffiti-marked pedestal stood on its platform in the run-down remains of Haymarket Square where it was known as an anarchist landmark.[126] On June 1, 2007, the statue was rededicated at Chicago Police Headquarters with a new pedestal, unveiled by Geraldine Doceka, Officer Mathias Degan's great-granddaughter.[123]

In 1992, the site of the speakers' wagon was marked by a bronze plaque set into the sidewalk, reading:

"A decade of strife between labor and industry culminated here in a confrontation that resulted in the tragic death of both workers and policemen. On May 4, 1886, spectators at a labor rally had gathered around the mouth of Crane's Alley. A contingent of police approaching on Des Plaines Street were met by a bomb thrown from just south of the alley. The resultant trial of eight activists gained worldwide attention for the labor movement, and initiated the tradition of 'May Day' labor rallies in many cities."

The marker under the Mary Brogger monument, vandalized

On September 14, 2004, Daley and union leaders—including the president of Chicago's police union—unveiled a monument by Chicago artist Mary Brogger, a fifteen-foot speakers' wagon sculpture echoing the wagon on which the labor leaders stood in Haymarket Square to champion the eight-hour day.[129] The bronze sculpture, intended to be the centerpiece of a proposed "Labor Park", is meant to symbolize both the rally at Haymarket and free speech. The planned site was to include an international commemoration wall, sidewalk plaques, a cultural pylon, a seating area, and banners, but construction has not yet begun.

As of 2014, a feature motion picture is being produced about the Haymarket affair, the events leading up to it, and its aftermath.
