EXPLANATIONS BELOW
Concept note-1: -Arguably the most profound effect of World War I on African Americans was the acceleration of the multi-decade mass movement of black, southern rural farm laborers northward and westward to cities in search of higher wages in industrial jobs and better social and political opportunities.
Concept note-2: -As a result of the Union victory in the Civil War and the ratification of the Thirteenth Amendment to the Constitution (1865), nearly four million slaves were freed. The Fourteenth Amendment (1868) granted African Americans citizenship, and the Fifteenth Amendment (1870) guaranteed their right to vote.
Concept note-3: -More than 350, 000 African Americans served in World War I. Among those sent overseas, the majority served in support battalions, reflecting the belief that Black men were suited more for manual labor than front-line combat.
Concept note-4: -Black draftees were treated with extreme hostility when they arrived for training. White men refused to salute black officers and black officers were often barred from the officer’s clubs and quarters. The War Department rarely interceded, and discrimination was usually overlooked or sometimes condoned.
