American Federation of Labor and Congress of Industrial Organizations

History

The American Federation of Labor (AFL) was founded in 1886 as a national federation of labor unions in the United States. It was led by Samuel Gompers and primarily consisted of craft unions. Over time, the AFL became the largest federation of labor unions in the U.S., but it faced challenges in organizing industrial workers.

The Congress of Industrial Organizations (CIO) emerged in 1935 within the AFL, initially as the Committee for Industrial Organization, led by John L. Lewis. The CIO focused on organizing workers in mass production industries, unlike the AFL's focus on craft unions. After being expelled from the AFL, the CIO became an independent federation in 1938. The CIO played a significant role in organizing workers in industries such as steel, rubber, and automobiles during the Great Depression.

Merger and Legacy

In 1955, the AFL and CIO merged to form the AFL-CIO, which is still the largest labor federation in the United States today. This merger united the craft and industrial unions under a single banner, ending years of rivalry between the two organizations.
