Established in 1886, the American Federation of Labor is an umbrella organization for other unions.
In 1881, Samuel Gompers took the lead in organizing the Federation of Organized Trades and Labor Unions of the United States of America and Canada. This organization became the American Federation of Labor (AFL) in 1886, in Columbus, Ohio. Many members of these two groups were disgruntled members of the Knights of Labor, the most influential organization of unions in the United States during the 1870s. Gompers served as the AFL's first president. He remained the organization's president, other than for one year, until his death in 1924. Under Gompers's leadership, the AFL became the largest labor union organization in the United States. The AFL initially allowed only skilled workers to join the organization. Unskilled laborers initially did not have representation under the AFL. The group also originally prohibited women, African Americans, and other racial minorities from joining the organization. Gompers supported the use of strikes, but he preferred peaceful negotiations to attain fair contracts for workers from their employers. He also sought to keep the AFL out of the political arena, believing that political activity might offend some business owners and hinder the workers' ability to attain better conditions.
