‘On the Edge of Freedom’ explores in captivating detail the fugitive slave issue through fifty years of sectional conflict, war, and reconstruction in south central Pennsylvania and provocatively questions what was gained by the activists’ pragmatic approach of emphasizing fugitive slaves over immediate abolition and full equality. Smith argues that after the war, social and demographic changes in southern Pennsylvania worked against African Americans’ achieving equal opportunity, and although local literature portrayed this area as a vanguard of the Underground Railroad, African Americans still lived “on the edge of freedom.” By the 1920s, the Ku Klux Klan was rallying near the Gettysburg battlefield, and south central Pennsylvania became, in some ways, as segregated as the Jim Crow South. The fugitive slave issue, by reinforcing images of dependency, may have actually worked against the achievement of lasting social change.
