The writer, scholar and activist, W.E.B. Du Bois described blacks as living "behind the veil" during Jim Crow. The metaphor described a vibrant social and political system developed by African Americans to bear the hardships of segregation and prejudice, behind which they remained largely invisible and thereby unthreatening to whites. Exclusion from white society forced blacks to build their own social institutions churches, schools, social clubs which were vital to fighting segregation, improving black economic conditions and generally "uplifting" the race.
