Whatever may have been the conditions resulting from the influx of Negroes, they were undoubtedly actuated by a desire to improve their condition. Some 10,000 or 12,000 Negroes had come to St. Clair County from the South during the winter of 1916-17. During the year and a half preceding the riot, the number of such migrants was estimated at 18,000, although it was reported that many had returned during the winter of 1916-17, because of the unaccustomed cold climate. It is certain that this influx severely taxed the housing accommodations of East St. Louis, which were of the insanitary and inadequate nature that so often characterizes urban districts in which the Negroes find that they must live. The report of the Congressional Committee on this point says:
It is a lamentable fact that the employers of labor paid too little heed to the comfort or welfare of their men. They saw them crowded into wretched cabins without water or any of the conveniences of life, their wives and children condemned to live in the disreputable quarters of the town, and made no effort to lift them out of the mire. The Negroes gravitated to the insanitary sections, existed in the squalor of filthy cabins and made no complaint, but the white workmen had a higher outlook, and failure to provide them with better homes added to their bitter dissatisfaction with the burdens placed upon them by having to compete with black labor.
It is likewise in evidence that special inducements were offered to the southern Negroes to come to East St. Louis, as well as to other industrial centers in the North. Advertisements were placed in southern newspapers, offering employment at wages far in excess of those paid in the South. Low railroad rates were offered, and in some instances during this general migration the railroads are said to have transported Negroes free in order that they might be employed by the railroads. Failures of crops in the South, floods and ill treatment of Negroes there, coupled with the hope that they would find fairer treatment in the North, as well as better wages and living conditions, were the direct causes of migration. After this had become fairly general it was further stimulated by Negroes who had come North, and who wrote home painting northern conditions in glowing colors.
From the industrial point of view it should be noted that in the summer of 1916 there had been a strike of 4,000 white men in the packing-plants of East St. Louis. It was asserted that Negroes were used in these plants as strike breakers. A report on the Negro migration by the United States Department of Labor states that when the strike was ended Negroes were still employed, and some of the white men lost their positions. It says further: "The white leaders undoubtedly realized that the effectiveness of striking was materially lessened by this importation of black workers."
Furthermore, it is stated in the report of the Congressional Committee that the Aluminum Ore Company, during a strike, brought hundreds of Negroes to the city as strike breakers in order to defeat organized labor, "a precedent which aroused intense hatred and antagonism, and caused countless tragedies as its aftermath. The feeling of resentment grew with each succeeding day. White men walked the streets in idleness and their families suffered for food and warmth and clothes, while their places as laborers were taken by strange Negroes who were compelled to live in hovels and who were used to keep down wages."
In May, 1917, a strike followed demands which had been made upon the Aluminum Ore Company by the "Aluminum Ore Employees' Protective Association." These related to alleged injustices and discriminations said to have been practiced against the employees. The company failed to comply with these demands, and a thousand white workers struck.
Closely related to this situation was a notice sent to the delegates of the Central Trades Labor Union by the secretary of the Union, dated May 23, which declared that the immigration of the southern Negro had reached a point where "drastic action must be taken if we intend to work and to live peaceably in this community." This notice declared that these men were being used "to the detriment of our white citizens by some of the capitalists and a few real estate owners." It called a meeting to present to the mayor and city council a demand for action to "retard this growing menace, and also devise a way to get rid of a certain portion of those who are already here." The notice read further: "This is not a protest against the Negro who has long been a resident of East St. Louis, and is a law abiding citizen."
This meeting was held on May 28 in the auditorium of the city hall and was attended not only by the labor men but also by a large number of other persons. The Congressional Committee refers to one of the speakers at this meeting as "an attorney of some ability and no character." The report of the Committee says that he virtually advised the killing of Negroes and burning of their homes. The report says further:
He was not authorized to speak for those who went there to protest against the lawlessness which disgraced the city and the presence of thousands of Negroes who it is claimed were taking the places of the white workmen, but his inflammatory speech caused many of his hearers to rush into the street and to resort to acts of violence.... He was in full sympathy with the action of the mob. They followed his advice and the scenes of murder and arson that ensued were the logical result of his utterances.
That night, May 28, following the meeting, a crowd of white people assembled in front of the police station and clamored for Negro prisoners. A rumor circulated through the crowd that a white man had just been killed by Negroes, and parts of the crowd left, forming a mob which severely beat a number of Negroes whom it met. The situation was so serious that the mayor called for troops. The trouble subsided, however. It is important to note that from this time until the riot of July 1-2, no effort was made to strengthen the police force nor were any other steps taken to control the situation.
