Twenty persons appeared to testify before the committee in favor of the bill, of whom all but two or three belonged to the Knights of Labor. The anti-contract labor law which was passed by Congress on February 2, 1885, therefore, was due almost entirely to the efforts of the Knights of Labor. The trade unions gave little active support, for to the skilled workingmen the importation of contract Italian and Hungarian laborers was a matter of small importance. On the other hand, to the Knights of Labor with their vast contingent of unskilled it was a strong menace. Although the law could not be enforced and had to be amended in 1887 in order to render it effective, its passage nevertheless attests the political influence already exercised by the Order in 1885.
The outcome of the Gould strike of 1885 and the dramatic exaggeration of the prowess of the Order by press and even by pulpit were largely responsible for the psychological setting that called forth and surrounded the great upheaval of 1886. This upheaval meant more than the mere quickening of the pace of the movement begun in preceding years and decades. It signalled the appearance on the scene of a new class which had not hitherto found a place in the labor movement, namely the unskilled. All the peculiar characteristics of the dramatic events in 1886 and 1887, the highly feverish pace at which organizations grew, the nation-wide wave of strikes, particularly sympathetic strikes, the wide use of the boycott, the obliteration, apparently complete, of all lines that divided the laboring class, whether geographic or trade, the violence and turbulence which accompanied the movement—all of these were the signs of a great movement by the class of the unskilled, which had finally risen in rebellion. This movement, rising as an elemental protest against oppression and degradation, could be but feebly restrained by any considerations of expediency and prudence; nor, of course, could it be restrained by any lessons from experience. But, if the origin and powerful sweep of this movement were largely spontaneous and elemental, the issues which it took up were supplied by the existing organizations, namely the trade unions and the Knights of Labor. These served also as the dykes between which the rapid streams were gathered and, if at times it seemed that they must burst under the pressure, still they gave form and direction to the movement and partly succeeded in introducing order where chaos had reigned. The issue which first brought unity in this great mass movement was a nation-wide strike for the eight-hour day declared for May 1, 1886.
The initiative in this strike was taken not by the Order but by the trade unionists and on the eve of the strike the general officers of the Knights adopted an attitude of hostility. But if the slogan failed to arouse the enthusiasm of the national leaders of the Knights, it nevertheless found ready response in the ranks of labor. The great class of the unskilled and unorganized, which had come to look upon the Knights of Labor as the all-powerful liberator of the laboring masses from oppression, now eagerly seized upon this demand as the issue upon which the first battle with capital should be fought.
The agitation assumed large proportions in March. The main argument for the shorter day was work for the unemployed. With the exception of the cigar makers, it was left wholly in the hands of local organizations. The Knights of Labor as an organization figured far less prominently than the trade unions, and among the latter the building trades and the German-speaking furniture workers and cigar makers stood in the front of the movement. Early in the strike the workingmen's cause was gravely injured by a bomb explosion on Haymarket Square in Chicago, attributed to anarchists, which killed and wounded a score of policemen.
The bomb explosion on Haymarket Square connected two movements which had heretofore marched separately, despite a certain mutual affinity. For what many of the Knights of Labor were practising during the upheaval in a less drastic manner and without stopping to look for a theoretical justification, the contemporary Chicago "anarchists,"[19] the largest branch of the "Black International," had elevated into a well rounded-out system of thought. Both syndicalism and the Knights of Labor upheaval were related chapters in the revolutionary movement of the eighties. Whether in its conscious or unconscious form, this syndicalism was characterized by an extreme combativeness, by the ease with which minor disputes grew into widespread strikes involving many trades and large territories, by a reluctance, if not an out and out refusal, to enter into agreements with employers however temporary, and lastly by a ready resort to violence. In 1886 the membership of the Black International probably was about 5000 or 6000 and of this number about 1000 were English speaking.
The circumstances of the bomb explosion were the following. A strikers' meeting was held near the McCormick Reaper Works in Chicago, late on the third of May. About this time strike-breakers employed in these works began to leave for home and were attacked by strikers. The police arrived in large numbers and upon being received with stones, fired and killed four and wounded many. The same evening the International issued a call in which appeared the word "Revenge" with the appeal: "Workingmen, arm yourselves and appear in full force." A protest mass meeting met the next day on Haymarket Square and was addressed by Internationalists. The police were present in numbers and, as they formed in line and advanced on the crowd, some unknown hand hurled a bomb into their midst killing and wounding many.
It is unnecessary to describe here the period of police terror in Chicago, the hysterical attitude of the press, or the state of panic that came over the inhabitants of the city. Nor is it necessary to deal in detail with the trial and sentence of the accused. Suffice it to say that the Haymarket bomb showed to the labor movement what it might expect from the public and the government if it combined violence with a revolutionary purpose.
Although the bomb outrage was attributed to the anarchists and not generally to the strikers for the eight-hour day, it did materially reduce the sympathy of the public as well as intimidate many strikers. Nevertheless, Bradstreet's estimated that no fewer than 340,000 men took part in the movement; 190,000 actually struck, only 42,000 of this number with success, and 150,000 secured shorter hours without a strike. Thus the total number of those who secured with or without strikes the eight-hour day was something less than 200,000. But even those who for the present succeeded, whether with or without striking, soon lost the concession, and Bradstreet's estimated in January, 1887, that, so far as the payment of former wages for a shorter day's work is concerned, the grand total of those retaining the concession did not exceed, if it equalled, 15,000.
American labor movements have never experienced such a rush to organize as the one in the latter part of 1885 and during 1886. During 1886 the combined membership of labor organizations was exceptionally large and for the first time came near the million mark. The Knights of Labor had a membership of 700,000 and the trade unions at least 250,000, the former composed largely of unskilled and the latter of skilled. The Knights of Labor gained in a remarkably short time—in a few months—over 600,000 new members and grew from 1610 local assemblies with 104,066 members in good standing in July 1885, to 5892 assemblies with 702,924 members in July 1886. The greatest portion of this growth occurred after January 1, 1886. In the state of New York there were in July 1886, about 110,000 members (60,809 in District Assembly 49 of New York City alone); in Pennsylvania, 95,000 (51,557 in District Assembly 1, Philadelphia, alone); in Massachusetts, 90,000 (81,191 in District Assembly 30 of Boston); and in Illinois, 32,000.
In the state of Illinois, for which detailed information for that year is available, there were 204 local assemblies with 34,974 members, of which 65 percent were found in Cook County (Chicago) alone. One hundred and forty-nine assemblies were mixed, that is comprised members of different trades including unskilled and only 55 were trade assemblies. Reckoned according to country of birth the membership was 45 percent American, 16 percent German, 13 percent Irish, 10 percent British, 5 percent Scandinavian, and the remaining 2 percent scattered. The trade unions also gained many members but in a considerably lesser proportion.
