Concept note-1: -The service of African-Americans in the military had dramatic implications for African-Americans. Black soldiers faced systemic racial discrimination in the army and endured virulent hostility upon returning to their homes at the end of the war.
Concept note-2: -After the declaration of war, more than 20, 000 blacks enlisted in the military, and the numbers increased when the Selective Service Act was enacted in May 1917. It was documented on July 5, 1917 that over 700, 000 African Americans had registered for military service.
