Although the American Federation of Labor did not profess racial discrimination as a deliberate national policy, many of its individual trade unions did, and, because of its federated structure, the A. F. of L. had no power over local discriminatory practices. Whites in skilled trades used unions to maintain an exclusive control in those trades, and they deliberately strove to relegate blacks to the lower ranks of industrial labor. Barred from the road to advancement, black labor became a permanent industrial proletariat. The Freedmen's Bureau was the one federal attempt to raise the social and economic standing of the ex-slave. Along with the American Missionary Association, the Freedmen's Bureau did significant work in education. Hundreds of teachers staffed scores of schools and brought some degree of literacy and job skills to thousands of pupils. However, beyond the field of education, the bureau did little except to provide temporary help. Begun as a war measure, when the Radical Republicans came into control, they put it on a more permanent footing. Even liberals, however, were not prepared to support a long-term social experiment, and, after some half dozen years, the Bureau was terminated. This left the Afro-American community without the economic base necessary for competing in American society on an equal basis. The one achievement of Reconstruction had been to guarantee minimum of political and civil rights to the ex-slave, but white supremacy advocates were adamant in their intention to destroy this advance. Where terror and intimidation were not successful, relentless economic pressure by landowners, merchants, and industrialists brought most of the ex-slaves into line. Year by year they exerted less influence at the voting booths. Although the country was aware of this, Northern liberals were growing weary of the unending fight to protect the freedman. Furthermore, masses of Northern whites sympathized with Southern race prejudice. While they did approve of ending slavery, they were not willing to extend social and political equality. The North had begun to put a higher priority on peace than on justice. Industrialists were expanding their businesses rapidly, and they wanted the South to be pacified, so that it would be a safe area for investment and expansion. If this meant returning power to white conservatives, they were willing to pay the price. The presidential election of 1876 degenerated into chaos and confusion. Samuel J. Tilden, the Democratic candidate, and Rutherford B. Hayes, the Republican, disputed its results. Democrats and Republicans both claimed twenty electoral votes from Georgia, Louisiana, South Carolina, and Florida. The first returns had shown that Tilden was the victor, but Republicans, especially Army veterans, warned that they would not accept such a result. The Republicans represented themselves as the party of the Union, and they claimed that the Democrats were the party of secession. The
