The Brotherhood of Sleeping Car Porters holds a significant place in Black history as the first labor union led by African Americans to receive a charter from the American Federation of Labor. Formed in 1925 by A. Philip Randolph, the union sought to improve the working conditions and rights of Pullman Company porters, who were predominantly African American.

Porters faced long hours, low pay, and discrimination on the job, including being treated as subservient to white passengers. The Brotherhood of Sleeping Car Porters fought for fair wages, shorter working hours, and better treatment on the job.

One of the key achievements of the Brotherhood of Sleeping Car Porters was the signing of the first labor agreement between a Black labor union and a major U.S. corporation in 1937. This milestone marked a significant victory for the rights of Black workers and laid the groundwork for future labor movements.

The Brotherhood of Sleeping Car Porters played a crucial role in the civil rights movement, advocating for economic justice and equality for Black workers. The union's success paved the way for other Black-led labor organizations and contributed to the broader struggle for equality and justice in America.
