During the 20th century, civil rights organizers began to develop ideas for a march on Washington, DC to seek justice. Earlier efforts to organize such a demonstration included the March on Washington Movement of the 1940s. A. Philip Randolph—the president of the Brotherhood of Sleeping Car Porters, president of the Negro American Labor Council, and vice president of the AFL-CIO—was a key instigator in 1941. With Bayard Rustin, Randolph called for 100,000 black workers to march on Washington, in protest of discriminatory hiring during World War II by U.S. military contractors and demanding an Executive Order to correct that. Faced with a mass march scheduled for July 1, 1941, President Franklin D. Roosevelt issued Executive Order 8802 on June 25. The order established the Committee on Fair Employment Practice and banned discriminatory hiring in the defense industry, leading to improvements for many defense workers. Randolph called off the March.
