A. A March on Washington

Explanation:

Beginning in 1941, black activists A. Philip Randolph and Bayard Rustin planned a march by blacks on Washington that would be attended by thousands of people to protest against discrimination against black people in defence industries and in the American armed forces.  

The threat of this March persuaded President Roosevelt to sign Executive Order 8802 which mandated that all defence companies receiving Government contracts abstain from discriminatory practices and set up the Fair Employment Practices Committee (FEPC) to monitor this order.

The initial march was then cancelled after the signing of this Order.
