Efforts to write the history of the African American migrations of the Civil War era, the Gilded Age, and the Progressive Era began soon after the start of these historically significant movements. Early scholarship labored to surmount the same methodological obstacles faced by modern scholars, notably scarce documentation, but still produced pathbreaking studies such as W. E. B. Du Bois'sThe Philadelphia Negro, Carter Woodson'sA Century of Negro Migration, and Clyde Kiser'sSea Island to City. Modern scholarship since the 1950s falls into eight distinct genres. An assessment of representative works in each genre reveals a variety of configurations of strengths and weaknesses, while offering guidelines for future research.
