The purpose of this study was to provide a comparative, historical, institutional analysis of the Tuskegee University Moveable School, founded in 1906, and the Atlanta University People's College, established in 1942. Both programs are early exemplars of social justice education as it was practiced at Historically Black Colleges and Universities (HBCUs) during the era of Jim Crow-- a time predating more recent developments in Community-Based Research (CBR) history, theory and practice. The CBR social justice education model has been endemic to the HBCU program since the mid-1800s, before its naming or professionalization in the fields of adult, higher and social justice education. This study also illuminated, in a broader context, issues regarding the following questions: 1) What were the social, historical and cultural contexts within which social justice education emerged at Atlanta and Tuskegee Universities?; How was social justice education actualized at Atlanta and Tuskegee Universities through the Moveable School and the People's College? and 3) How did social justice education history, theory and practice compare and vary institutionally and programmatically? Document analysis was the primary method of research utilized for this study. The exploration was conducted through an extensive review of the available primary and secondary resource information on the Moveable School and the People's College. The archival document holdings were accessed by visiting the National Center for Bioethics Research Archives located at Tuskegee University; the Robert W. Woodruff, Atlanta University Center Archives and the Atlanta-Fulton Public Library System, Auburn Avenue Research Library on African-American Culture Archives. The key findings resulting from the archival research reveal the Moveable School and the People's College as two early exemplars of an HBCU model of social justice education. This study, therefore, substantiates both programs as precursors to the more recent and widely propagated scholarly discourse around CBR. Social justice education, a phenomenon intrinsic to HBCUs since the early 19th century, was historically utilized as a tool for engaging the social, political and economic injustices threating the collective progression of Black communities.
