This collection uses primary sources to explore the experiences of African American Soldiers in World War I. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

Students are asked to use the provided source material to answer the central historical question: Why did African Americans join the Union Army during the Civil War?
