From An Anarchist FAQ:
May 1st is a day of special significance for the labour movement. While it has been hijacked in the past by the Stalinist bureaucracy in the Soviet Union and elsewhere, the labour movement festival of May Day is a day of world-wide solidarity. A time to remember past struggles and demonstrate our hope for a better future. A day to remember that an injury to one is an injury to all.
The history of Mayday is closely linked with the anarchist movement and the struggles of working people for a better world. Indeed, it originated with the execution of four anarchists in Chicago in 1886 for organising workers in the fight for the eight-hour day. Thus May Day is a product of "anarchy in action" -- of the struggle of working people using direct action in labour unions to change the world.
It began in the 1880s in the USA. In 1884, the Federation of Organised Trades and Labor Unions of the United States and Canada (created in 1881, it changed its name in 1886 to the American Federation of Labor) passed a resolution which asserted that "eight hours shall constitute a legal day's work from and after May 1, 1886, and that we recommend to labour organisations throughout this district that they so direct their laws as to conform to this resolution." A call for strikes on May 1st, 1886 was made in support of this demand.
In Chicago the anarchists were the main force in the union movement, and partially as a result of their presence, the unions translated this call into strikes on May 1st. The anarchists thought that the eight hour day could only be won through direct action and solidarity. They considered that struggles for reforms, like the eight hour day, were not enough in themselves. They viewed them as only one battle in an ongoing class war that would only end by social revolution and the creation of a free society. It was with these ideas that they organised and fought.
In Chicago alone, 400 000 workers went out and the threat of strike action ensured that more than 45 000 were granted a shorter working day without striking. On May 3, 1886, police fired into a crowd of pickets at the McCormick Harvester Machine Company, killing at least one striker, seriously wounding five or six others, and injuring an undetermined number. Anarchists called for a mass meeting the next day in Haymarket Square to protest the brutality. According to the Mayor, "nothing had occurred yet, or looked likely to occur to require interference." However, as the meeting was breaking up a column of 180 police arrived and ordered the meeting to end. At this moment a bomb was thrown into the police ranks, who opened fire on the crowd. How many civilians were wounded or killed by the police was never exactly ascertained, but 7 policemen eventually died (ironically, only one was the victim of the bomb, the rest were a result of the bullets fired by the police [Paul Avrich, The Haymarket Tragedy, p. 208]).
A "reign of terror" swept over Chicago, and the "organised banditti and conscienceless brigands of capital suspended the only papers which would give the side of those whom they crammed into prison cells. They have invaded the homes of everyone who has ever known to have raised a voice or sympathised with those who have aught to say against the present system of robbery and oppression . . . they have invaded their homes and subjected them and their families to indignities that must be seen to be believed." [Lucy Parsons, Liberty, Equality & Solidarity, p. 53] Meeting halls, union offices, printing shops and private homes were raided (usually without warrants). Such raids into working-class areas allowed the police to round up all known anarchists and other socialists. Many suspects were beaten up and some bribed. "Make the raids first and look up the law afterwards" was the public statement of J. Grinnell, the States Attorney, when a question was raised about search warrants. ["Editor's Introduction", The Autobiographies of the Haymarket Martyrs, p. 7]
Eight anarchists were put on trial for accessory to murder. No pretence was made that any of the accused had carried out or even planned the bomb. The judge ruled that it was not necessary for the state to identify the actual perpetrator or prove that he had acted under the influence of the accused. The state did not try to establish that the defendants had in any way approved or abetted the act. In fact, only three were present at the meeting when the bomb exploded and one of those, Albert Parsons, was accompanied by his wife and fellow anarchist Lucy and their two small children to the event.
The reason why these eight were picked was because of their anarchism and union organising, as made clear by that State's Attorney when he told the jury that "Law is on trial. Anarchy is on trial. These men have been selected, picked out by the Grand Jury, and indicted because they were leaders. They are no more guilty than the thousands who follow them. Gentlemen of the jury; convict these men, make examples of them, hang them and you save our institutions, our society." The jury was selected by a special bailiff, nominated by the State's Attorney and was explicitly chosen to compose of businessmen and a relative of one of the cops killed. The defence was not allowed to present evidence that the special bailiff had publicly claimed "I am managing this case and I know what I am about. These fellows are going to be hanged as certain as death." [Op. Cit., p. 8] Not surprisingly, the accused were convicted. Seven were sentenced to death, one to 15 years' imprisonment.
An international campaign resulted in two of the death sentences being commuted to life, but the world wide protest did not stop the US state. Of the remaining five, one (Louis Lingg) cheated the executioner and killed himself on the eve of the execution. The remaining four (Albert Parsons, August Spies, George Engel and Adolph Fischer) were hanged on November 11th 1887. They are known in Labour history as the Haymarket Martyrs. Between 150,000 and 500,000 lined the route taken by the funeral cortege and between 10,000 to 25,000 were estimated to have watched the burial.
In 1889, the American delegation attending the International Socialist congress in Paris proposed that May 1st be adopted as a workers' holiday. This was to commemorate working class struggle and the "Martyrdom of the Chicago Eight". Since then Mayday has became a day for international solidarity. In 1893, the new Governor of Illinois made official what the working class in Chicago and across the world knew all along and pardoned the Martyrs because of their obvious innocence and because "the trial was not fair." To this day, no one knows who threw the bomb -- the only definite fact is that it was not any of those who were tried for the act: "Our comrades were not murdered by the state because they had any connection with the bomb-throwing, but because they had been active in organising the wage-slaves of America." [Lucy Parsons, Op. Cit., p. 142]
The authorities had believed at the time of the trial that such persecution would break the back of the labour movement. As Lucy Parsons, a participant of the events, noted 20 years later, the Haymarket trial "was a class trial -- relentless, vindictive, savage and bloody. By that prosecution the capitalists sought to break the great strike for the eight-hour day which as being successfully inaugurated in Chicago, this city being the stormcentre of that great movement; and they also intended, by the savage manner in which they conducted the trial of these men, to frighten the working class back to their long hours of toil and low wages from which they were attempting to emerge. The capitalistic class imagined they could carry out their hellish plot by putting to an ignominious death the most progressive leaders among the working class of that day. In executing their bloody deed of judicial murder they succeeded, but in arresting the mighty onward movement of the class struggle they utterly failed." [Lucy Parsons, Op. Cit., p. 128] In the words of August Spies when he addressed the court after he had been sentenced to die:
"If you think that by hanging us you can stamp out the labour movement . . . the movement from which the downtrodden millions, the millions who toil in misery and want, expect salvation -- if this is your opinion, then hang us! Here you will tread on a spark, but there and there, behind you -- and in front of you, and everywhere, flames blaze up. It is a subterranean fire. You cannot put it out." [quoted by Paul Avrich, Op. Cit., p. 287]
At the time and in the years to come, this defiance of the state and capitalism was to win thousands to anarchism, particularly in the US itself. Since the Haymarket event, anarchists have celebrated May Day (on the 1st of May -- the reformist unions and labour parties moved its marches to the first Sunday of the month). We do so to show our solidarity with other working class people across the world, to celebrate past and present struggles, to show our power and remind the ruling class of their vulnerability. As Nestor Makhno put it:
"That day those American workers attempted, by organising themselves, to give expression to their protest against the iniquitous order of the State and Capital of the propertied . . .
"The workers of Chicago . . . had gathered to resolve, in common, the problems of their lives and their struggles. . .
"Today too . . . the toilers . . . regard the first of May as the occasion of a get-together when they will concern themselves with their own affairs and consider the matter of their emancipation." [The Struggle Against the State and Other Essays, pp. 59-60]
Anarchists stay true to the origins of May Day and celebrate its birth in the direct action of the oppressed. It is a classic example of anarchist principles of direct action and solidarity, "an historic event of great importance, inasmuch as it was, in the first place, the first time that workers themselves had attempted to get a shorter work day by united, simultaneous action . . . this strike was the first in the nature of Direct Action on a large scale, the first in America." [Lucy Parsons, Op. Cit., pp. 139-40] Oppression and exploitation breed resistance and, for anarchists, May Day is an international symbol of that resistance and power -- a power expressed in the last words of August Spies, chiselled in stone on the monument to the Haymarket martyrs in Waldheim Cemetery in Chicago:
"The day will come when our silence will be more powerful than the voices you are throttling today."
To understand why the state and business class were so determined to hang the Chicago Anarchists, it is necessary to realise they were considered the leaders of a massive radical union movement. In 1884, the Chicago Anarchists produced the world's first daily anarchist newspaper, the Chicagoer Arbeiter-Zeiting. This was written, read, owned and published by the German immigrant working class movement. The combined circulation of this daily plus a weekly (Vorbote) and a Sunday edition (Fackel) more than doubled, from 13,000 per issues in 1880 to 26,980 in 1886. Anarchist weekly papers existed for other ethnic groups as well (one English, one Bohemian and one Scandinavian).
Anarchists were very active in the Central Labour Union (which included the eleven largest unions in the city) and aimed to make it, in the words of Albert Parsons (one of the Martyrs), "the embryonic group of the future 'free society.'" The anarchists were also part of the International Working People's Association (also called the "Black International") which had representatives from 26 cities at its founding convention. The I.W.P.A. soon "made headway among trade unions, especially in the mid-west" and its ideas of "direct action of the rank and file" and of trade unions "serv[ing] as the instrument of the working class for the complete destruction of capitalism and the nucleus for the formation of a new society" became known as the "Chicago Idea" (an idea which later inspired the Industrial Workers of the World which was founded in Chicago in 1905). ["Editor's Introduction," The Autobiographies of the Haymarket Martyrs, p. 4]
This idea was expressed in the manifesto issued at the I.W.P.A.'s Pittsburgh Congress of 1883:
"First -- Destruction of the existing class rule, by all means, i.e. by energetic, relentless, revolutionary and international action.
"Second -- Establishment of a free society based upon co-operative organisation of production.
"Third -- Free exchange of equivalent products by and between the productive organisations without commerce and profit-mongery.
"Fourth -- Organisation of education on a secular, scientific and equal basis for both sexes.
"Fifth -- Equal rights for all without distinction to sex or race.
"Sixth -- Regulation of all public affairs by free contracts between autonomous (independent) communes and associations, resting on a federalistic basis." [Op. Cit., p. 42]
In addition to their union organising, the Chicago anarchist movement also organised social societies, picnics, lectures, dances, libraries and a host of other activities. These all helped to forge a distinctly working-class revolutionary culture in the heart of the "American Dream." The threat to the ruling class and their system was too great to allow it to continue (particularly with memories of the vast uprising of labour in 1877 still fresh. As in 1886, that revolt was also meet by state violence -- see Strike! by J. Brecher for details of this strike movement as well as the Haymarket events). Hence the repression, kangaroo court, and the state murder of those the state and capitalist class considered "leaders" of the movement.
For more on the Haymarket Martyrs, their lives and their ideas, The Autobiographies of the Haymarket Martyrs is essential reading. Albert Parsons, the only American born Martyr, produced a book which explained what they stood for called Anarchism: Its Philosophy and Scientific Basis. Historian Paul Avrich's The Haymarket Tragedy is a useful in depth account of the events.
